FISHERIES Alaska in 1924; to Arnie J. Suomela, warden, who handled the work in southeastern Alaska in 1925; and to L. O. Wingard, warden, who conducted the tagging opera­ tions at Port Moller in 192,5. HarLl.n B. Holmes, junior aquatic biologist, rendered material aid in tabulating the data. The methods employed were almost the same as those followed in the experi­ ments conducted in the Alaska Peninsula region. These were fully described by Gilbert fl.nd Rich • and need not be set forth here. Scales were taken from each fish tagged in southeastern Alaska, but it was not considered necessary to do so in the experiment at Port Moller, as none but red salmon were taken at that place, and confusion of the various species was therefore impossible. In the experiments conducted in southeastern Alaska the species of each fish tagged was recorded in the books in which the scales were preserved, and the identification of each fish returned was made by examining the scales taken at the time of tagging. .A. small proportion of the fish was found to have boen incor­ rectly rccorded as to species, but the number was so small that it has not seemed worth while to examine the scales of the fish that were not recaptured. The only reason for doing so would be to render more accurate the figUres representing the total number of nsh of each species tagged in each experiment, but we have satisfied ourselves that any error that may result from accepting the data as given by the records made at the time of tagging will in no way affect our conclusions. The accompanying map of southeastern Alaska will serve to show the larger geographical features of that district, while the numerous minor localities from which returns were reported are included in the following list:

In giving the localities where tagged fish were captured, local names, which we have been unable to identify, were used occasionally. .As these cases were com­ paratively few, they have been onlltted from detailed consideration and have been included among those records with which no data wer submitted. Tagging operations were conducted in localities at or near the main channels through which the fish must pass in entering southeastern Alaska from the Pacific Ocean. The primary object of the experiments was to discover the main routes of salmon migration through the maze of channels of the and the distribution of the fish following these routes to the various spawning grounds. It was expected, also, that the experiments would yield information relative to the rate of migration of various species in various localities at various times. In so far as the routes of migration are concerned the results obtained were fa.irly satisfactory; but in many cases so few returns were received from anyone locality that the data as to th time that elapsed between tagging and recapture are not reliable enough to warro.nt detailed analysis. Th time available for the preparation of this report was not sufficient to permit as complete o.nd careful an analysis as is desirable. For various reasons, however, it seemed importo.nt to present the available facts without delay, and as the experi­ ments will be continued in subsequent years 8. more detailed analysis can be deferred until more data are at hand. EXPERIMENTS IN SOUTHEASTERN ALASKA TAGGING RECORD The following table gives the data for the tags attached in southeastern Alaska in 1924 and 1925. In cases where the numbers of fish tagged do not agree with the figures in the column headed "Serial numbers," the discrepancy is due to the loss or breaking of some of the tags.

These data indicate two ma.in routes of migration for the fish entering south­ eastern ~iliska through Icy Strait. Some of the fish turn southward upon reaching Chatha.m Strait and traverse this channel to its junction with Fr derick Sound, where three of the tagged nsh were taken. It is conceivable, of course, tha.t the fish taken in Frederick Sound may have reached there by another route, passing around the north end of Admiralty Island and south through tephens Passa.ge, but the evidence certainly favors the other hypothesis. No doubt some of the fish tali! n along this route were destined to enter local spawning streams on Admiralty, Chi­ Chigol, or Baranof Islands. 120 BULLETIN OF THE BUllEAU OP :rI8BEBIES Other fish entering Icy Strait tum north on Teaching Chatham Strait, traverse Lynn Canal I and in all probability find their ·spawning grounds in the Chilkat and Chilkoot Rivers at the head of the Canal. These rivers are noted for their red-salmon runs and probably are the two most important salmon streams in the northern part of southeastern Alaska. It is not surprising, therefore, that a migration to this . region is indicated. Only one tagged fish was taken outside of Icy Strait or one or the other of these two main lines of migration. Tha.t wa.s reported from Ground Hog BaYI near Juneau. COHOES A total of 133 cohoes was tagged in Icy Strait during 1925. Only 15 (11.3 per cent), representing only four experiments, were returned.

, See (ootnote 1 (0. Tabln 2 (p. UQ). The returns are too meager to show details of the migration from Icy Strait, but they indicate, unmistakably, that the main route is south in Chatham Strait. Only one fish w nt north, and it was retaken near the. northern end of Stephens Passage. One returned to the open ocean and was retaken on the outside coast of Baranof Island at Crawfish Inlet, and one went to Sumner Strait. Except for the fish r captured in Icy Strait or the immediate vicinity, the time that elapsed b tween tagging and recapturing was noticeably longer than was the cas with the red almon. Most of the red salmon tagged in Icy Strait and retaken in Chatham Strait were captured less than 20 days after they were tagged, but most of the cohoes were free for a much longer time (30 to 57 days). The significance of this is not clear, but it seems probable that the cohoes were taken close to their spawning grounds, while the reds taken in Chatham Strait were destined for more distant streams. It has been shown conclusively (by the tagging experiments along the Alaska. Peninsula) that salmon bound for distant streams travel at a more rapid rate than those bound for near-by spawning grounds. In this case the fact that the red &lmon spa.wn somewhat earlier than the cohoes 1Jl&y also have inftueneed their JllOl'e rapid progress. S.u...:t.fON TAGGING t ALASKA., 192.... 1t215 121

C1IUlrI8 The returns from the tagging of chum salmon in Icy Strait are given in Table 5. This species is somewhat more widely scattered than any of the others, but the essential features of the distribution are the same, the main route of the migration being south in Chatham Strait and thence to Frederick Sound. The wider distri­ bution of this species is indicated by the records of tags ta.ken in Rodman Bay and Hooniah Sound, Peril Strait; in Keku Strait; in Chatham Strait, south of the western entrance to Frederick Sound; in Sumner Strait; and at Cape Lynch, on Heeets. Island. There is also evidence of a. relatively unimportant northerly migration from Icy Strait into the region of Stephens Passage.

RETURNS FROM EXPERIMENTS IN CHATHAM STRAIT Five tagging experiments were conducted in Chatham Strait at or near Kings­ mill Point, on the norillw('stern shor of Kuiu Island, one on August 7, 1921, lind four between .July 10 and 15, 1925.

RED SALMON The returns for the red salmon tagged at Kingsmill Point are given in Table 7. Th majority of the recaptm were made in Frederick Sound and Stephens Passage, as far north as Taku Inlet. Four fish were taken in the Stikine River; and this, tog ther with the tact that relatively numerous returns were received from Frederick Sound, indicates that the tikine River is the source of an important part of the red-salmon run entering southeastern Alaslpl through Chatham Strait and Frederick Sound. Other tagged reds were taken in the southern part of Chatham Strait along the west TO (',oast of Kuiu Island, and three were taken in the southern part of Clarence Strait near Dixon Entrance. The e returns indicate a southerly migration of minor importance, possibly to the Nass and Skeena Rivers.

FINK SALMON In the five experiments conducted at Kingsmill Point 892 pink salmon w r tagged and 185 (20.7 per cent) were recaptured. The data aT given in 'i'able 9. As has been stated, the experiment of 1924 was made about thr weeks lilt r in the season than those of 1925. In spite of this the percentag of return was almost identical, a.lthough the distribution was differ nt. In 1924 a very gr at majority of the recaptures were made close to the point of tagging and in nea.r-by loca.lities in Frederick Sound. In 1925 a distinct migration south in Chatham trait was shown, which was not indicated in the results for 1924, and compara.tively few fish were taken close to the point of liberation. In other fe peets the returns for the two years were practically the same. A light movement north in Cha.tham Stra.it from Frederick Sound occurred, but the main migration wa. through Frederick 126 BULLETIN OF THE BUREAU OF PISHEBIES Sound and north in Stephens Passage as far as Tam Inlet. South of Kingsmill Pow t the :fish were di tributed mainly along the hores of Chatham Strait and Sumner trait, with a scattering few along the mainland in Ernest Sound, Behm Canal, and at Cape Chacon. It is interesting to note that none were taken along the western shore of Prince of Wales Island or on the smaller islands of the Prince of Wales Island or on the smaller islands of the Prince of Wales Archipelago.

Fairly good series of each species were tagged, especially in 1925, and the results are of correspondingly increa ed value and interest. As comparatively few retums were obtained in 1924, it has not seemed worth while to show in detail the data for each experiment of that year; therefore those referring to the reds, cohoes, and pinks have been combined in the tables. There appear to be significant differences in the results obtained from the experiments with chum salmon during July as compared with those for August, 1924, and in the table (Table 14) the data for the two months have been kept separate. The returns for each experiment of 1924 were studied separately, and it is believed that no information of importance is obscured by com­ bining the records. One striking feature of the returns is the great number of localities from which tagged fish were recorded. This is doubtless due to the intensity of the fishing in this region as well as to the character of the gear used, a great many small purse seines having been operated in the numerous small bays as well as traps in the main channels. RED SALMON The data relative to the red salmon tagged at Ruins Point are given in Table 11. The main route of migration clearly is through Sumner Strait and south in Clarence trait. b fish were recorded as taken north of Ruins Point in the region of Chatham Strait and Frederick ound, and 5 were taken along the west coast of Prince of Wales Island. 'The rest (with the exception of five doubtIul records), 169 in all, were taken along this one main migration route, in the adjacent waters, and in British Columbia. Seven were taken in the Stikine River and 5 at the hatchery of the Bureau of Fisheries on Lako McDonaldt tributary to Yes Bay. Two were taken in the Nass and 13 in the Skeena River. Othor local ·treams also doubtless contributed to the run of reds in the region of Ruins Point.

\ 130 BULLETIN OF THE BUREAU OF FISHERIES

COHOES The distribution of the cohoes tagged at Ruins Point was very much the same as that of the reds, except that a. much larger percentage was taken along the west shore of Prince of Wales Island and in the adjacent islands. Twenty-four (nearly 11 per c nt) of the recapture were reported from this loeality. Eight fi h were taken in Chatham Strait and one on the west COllst of Baranof Island, in Whale Bay. With the exception of these two localities, all of the other returns came from Sumner and Clarence Straits and the adjaant waters, with a few from British Co­ lumbia.. Table 12 shows the results of this experiment.

PINK SALMON The importance of local spawning runs of pink nlmon i w II iUtllltrated by the results of the tagging at Ruins Point, Ii shown in 'I'ablo 13. Out of a total of 555 returns, 352 fish (63.4 per cent) were taken in umner trait and adjac nt waters, A great many of these, as shown in the table, were taken in th imm diate vicinity of Ruins Point witrun a few days of the tagging. It WIlB reported that th fish were taken chiefly in purse seines operating just below Ruin Point in Sumner Strait, and it seems probable that some, at least, were bound for the small streams along the western shore of Prince of Wales Island and the hores of the small r islands of the Prince of Wales Archipelago. Thirty-four tagg d pink salmon wer actually reported from this region, and it seems probable that the number would 132 BULLETU OF THB BUREAU OP :rI8HDTES have been larger had it not been for the intensive fishery in Sumner Strait near the point of tagging. This region is therefore an important source of the pink salmon found in Sumner Strait. A few of the pinks went north and were taken in Chatham Strait, at Whale Ba.y on the western coast of Baranof Island, in Frederick Sound, and as far north as Seymour Canal in Stephen Passage. This northerly migration is of little prac­ tical importance, however, as only 10 tagged fish were reported from these regions. The r maining fish were taken in the waters of Clearance Strait, Ernest Sound, and Ravillagigedo Channel. None was taken in British Columbia. The local nature of the pink-salmon runs is further evidenced by the fact that a large per­ centage of the fish taken in Clarence Strait came from t.he northern part above Tolstoi Point and from Ernest Sound, just 100 fish being reported from these localities. Only 40 came from the southern part of Clarence Strait and 15 from Revillagigedo Channel. In the case of the reds and cohoes, the :fish were distributed about equally between the northern and the southern parts of Clarence Strait.

RETURNS FROM EXPERIMENTS AT CAPE MUZON AND KAICANI POINT Six tagging experiments were conducted here from August 15 to 22, 1925, inclusive. Out of a. total of 3,117 fish tagged, 3,049 were pink salmon, 7 were r d , 16 cohoes, and 45 chums. Very few returns were obtain d from sp cies other than the pink. One red salmon, tagged on August 15 at Cape Muzon, was taken at Kasook Inlet, Su'kkwan Island, on August 22. One coho, tagged on August 16 at Kaigani Point. was taken at Kassan Inlet, Cordova Bay, on August 22; and another, tagg d at Cape Muzon on August 22, was taken September 18 in Coco Bay, Dall Island. Of the chum salmon, one tagged a.t Ka.iga.ni Point on August 17 was ta.ken in Coco Bay on September 15. One of two fish tagged at Cape Muzon on August 22 was retaken at Hydaberg Creek on August 29 and the other in Coco nay on eptember 18. The scattering returns from these three species do not indicate any extensive or definite migration.

PINK SALMON Most of the salmon tagged at Cape Chacon were pinks. In five experiments conducted between August 8 and 13, 1925, inclusive, 2,341 fish of this species were tagg d. Of these 983 were recovered from a great many minor localities, mainly along the shores of Clarence Strait and the west coast of Prince of Wales Island. The locality of recapture was not recorded for 11 of the returns; 87 fish (8_8 per cent of the total number returned) were taken along the west coast of Prince of Wales Island; 1 was captured on the west shore of Kuiu Island in the southern part of Chatham Strait; 71 (7.2 per cent) were from Clarence Strait above 'l'olstoi Po.int;· and the remaining 813 (82.7 per cent) were taken in the southern part of Clarence Strait and adjacent waters.

CHUMS Two hundred and forty chum salmon were tagged, chiefly in the experiments of August 8 and 9, and of these 54 were returned. The distribution was much the same as in the case of the pink salmon, although a somewhat greater percentage of chums went to the west coast of Prince of Wales Island. Of the 54 returns 10 (18.5 per cent) Were from this region, and the remaining 44 (81.5 per cent) were taken in the general region including the southern part of Clarence Strait, Revillagigedo Channel, and adjacent water. None was taken north of Tolstoi Point in the Clarence Strait region. The data Ilre given in Table 19.

It is not possible, from the information at present available, to det nnine the causes for these wide fluctuations, or even to know whether the data. repres nt un­ usual or normal conditions. For instance, why were there appro:xitnately two and one-half times as many chums returned from the experim nts at Kingsmill Point, in Chatham Strait, as were returned from any other experiment i and why were so many more chums than sa.lmon of other species returned from these experim nts' These are questions that can be answered only when more data are availabl ,but it is quite apparent now tha.t the fishing for some species and in somo localities, at least, is so intensive as to require careful attention. It was pointed out in earlier tagging experiments j that these percentages of returns are always a minimum, and that

• Bee footlioU 2, p. 1011. 144 BULLETIN OF THE BUREAU OF nsmmus every factor that would modify the returns as we have them would increase the per­ centage of fish captur d and would indicate a greater intensity of fislllng than appears from the figure as given. Bearing this in mind, it is quite clear from the figures given above that the drain on some of the salmon runs in southeastern .Alaska must far exceed the limit set in certain other localities. In some ofthe streams of Alaska, notably the Karluk and Chignik: Rivers, where weirs are maintained in order that an accurate census of the spawning escapement may be taken, a 50 per cent escapement is required. Of course it is not possible to determine, in as complex a situation as that which exists in southeastern Alaska, just what th percentage of escapement to the various spawning areas is, but when 50 per cent of the released fish are again taken there can be no doubt that the actual drain on the resource is considerably gr ater than 50 per cent- so much greater as to menace the perpetuation of the upply. CONCLUSIONS It should be clearly understood that any general conclusions based on the data at present available are only tentative and must be considered as applying solely to those seasons of the year during which the tagging was done. It may very well be that the distribution at other times is quite different. Additional experiments have been planned and will be carried out in the future, which it is hoped will provide informa­ tion on this subject. Based on the data presented above, the following tentative conclusions seem warranted: 1. The main route of migration of the salmon entering southeastern Alaska. through Icy Strait is south in Chatham Strait and into Frederick Sound. In I\ddition a distinct migration of red salmon of relative importance takes place northward into Lynn Canal, where important spawning areas are located in the Chilka.t and Chilkoot Rivers. The experiments conducted farther south indicate that some of the red salmon there come from the rivers of northern British Columbia. There is no evidence to show that the reds of Icy Strait do so, for apparently their spawning grounds are confined to the region north of Frederick Sound. 2. Some of the fish found in Frederick Sound and Chatham Strait a.djacent to Frederick ound (Kingsmill Point) come from the north through Chatham Strait from Icy Strait, but it seems more than probable that many of them also enter through the south rn entrance to Chatham Strait. These fish are distributed throuO'hout Frede.rick Sound and Stephens Passage, and there is no evidence to show that the fish found in Frederick ound and tephens Passage enter these regions in any numbers xcept through Chatham trait and the western entrance to Frederick Sound. In addition to the distribution through Frederick Sound and Stephens Pas­ sage, there is a di tinct movement south through Chatham Strait and Kekn Strait, especially on the part of the chum salmon. As to the other species, this southerly migration seems to be of much less importance than that to the region of Frederick Sound and Stephens Passage. The tikine River apparently is an important spawning ground for reds a.nd cohoes. 3. The distribution of the fish tagged near the western entrance to Sumner Strait (Ruins Point) varies with the species, 'but it is almost entirely to the south, either along the western shore of Prince of Wales Island or in Clarence Strait. The red salmon were taken chiefly along Clarence Strait and in streams running from the SALMON TAGGING IN AI..ASlU., lOM-l9t3 145 Stikine River south into British Columbia. The coho were distributed ov thi same region and also along the western shore of Prin of Wal I land. Th pinks and chums were taken chiefly along the Wi rn hor of Prin f e.1 I and, in Sumner Strait and Clarence trait. Very few w r taken far from th waters, only one pink being r ported from the tikine River and non of eith r p' from British Columbia. 4. The sa.lmon taken at Dixon Entrance (Cap Muzon and ap Chacon) r predominantly of local races and wer distributed along th w tern shor of Prine of Wa.les Island and in Clarenc trait (mainly along th outh rn half), R ,,;n i do Channel, and adjacent waters. igni1icant numbers of both r ds and coho cam from th Nass and Skeena Riv rs in Northern British lumbia, but v f w of any of the other species were taken in Canadian waters. 5. The fish tagged in the region of Cape Fo ', Foggy Bay, and Duk I land (Dixon Entrance near the mainland) w r chiefly di tribut d locally alon the mainland shores, both in Ala. ka. and uth into Briti h lumbia. R ds, pink. , and chums were taken in the rivers of northern Briti h Columbia, p ially;n th and the Skeena. EXPERIMENTS AT PORT MOLLER, 1925 The purpose of the e:'Cperim nt conduct d at Port M 11 r w to the theory that almon taken off the mouths of th B ar and andy ivors r of local origin and are not bound for Bri tol Bay, are many of th· fish Lll.k n in tbe Ikatan-Shumagin Islands district. The tagging exp riment of 1922 how d clearly that in that year the fish taken in Bering a n ar til B ar and and Riv rs were local residents. Out of 639 tagged, not a single sp itn n w taken in Bristol Bay.e However, some of the cannery men inter t d in the fish ry at tbi point felt that the experiment of 1922 was not sufficiently conclusive, as it w po ible that 1922 was an unusual year. At their requ t th experim nt was r p at d during the summer of 1925, and 2,000 tags were attach d to salmon ta.k n with purse seines near the bea.ch between the Bear and andy Rivers. The methods followed were practically the sam as tho e in use eince 1922. slight modification was introduced, however, and the salmon, instead of being tagged and liberated directly from the gear in which they were aught, were first placed in alive car and towed 0. short distance fa.rther offshore. This was done to avoid interference with purse seines fishing close to shore, and a.lso b caus it was thought that the fish might have a better chance to esca.pe imm diaLe r captur . The tagging operations were planned by Dr. C. H. Gilbert, who visited H r n­ deen Bay late in June with the intention of immedia.t ly supervising Lh work. For various reasons this proved to be impossible, and the operations were actually carried out by L. G. Wingard, warden. The following numbers of ihe 1925 s ri of salmon tags were attached: 18001 to 18857 on July 1, 1885 to 19162 on July 4, and 19163 to 20000 on July 5. The results completely confirmed those or 1922. Out of the 2,000 fish tagged, 949, or 47.5 per cent, were recaptured and the tags returned to us. Of these only 1

'.All but two wero recorded 81 ~&li:en either luly 16 or 17. • All but tour or tbese were reeelved trom ODe company. which bad DOt submitted complete records at the tIme this paper was proparad. . The one fish ta.ken in Bristol Bay was No. 19337, tagged on July 5 and recap­ tured at Naknek on July 13. There is very little of interest in the results of this experiment other than the support it lends to the theory of the local origin of the fish taken in this region. The fact that a single individual was taken in Bristol Bay is entirely without practical signilicance. It may indicate tha.t an occasional Bristol Bay fish is to be found 8Jllong the schools of Bear and Sa.ndy River fish, or it may mean that an occasional Bear or Sa.ndy River :fish strays into Bristol Bay. We know that the homing instinct in salmon is not absolutely unerring, although we are equa.lly certain tha.t an over­ whelming percentage does return to the parent streams. It would not be surprising, therefore, if a few Bear or Sandy River fish did reach Bristol Ba.y, and the finding of one or even of several such cases would in no way affect the general conclusions. These may be summed up in the statement that in 1925, as in 1922, the fish found in Bering Sea in the vicinity of the Bear and Sandy Rivers were predominantly fish of local origin and were not natives of the important sa.lmon streams of Bristol Bay.
