As one of the activities of the UNDP/FAO 'Project for the Developn:ent of Fisheries in the Red Sea and Gulf of Aden' HAB/81/002 (previously HAB/77/008), a biological study of the Gulf of Suez and Egyptian Red Sea fisheries was corrmenced during late 1979. The study emphasis was directed towards the collection and analysis of data relevent to assessing the state of the stocks, and providing an irnproved basis upon v.hich to for- 1111late management advice. The data collection phase of the study was con tinued into 1982, at v.hich stage three years data were in hand.

This report is intended to be one of a series providing a collation of these data for each of the main fisheries types studied. It specifically deals with the purse seine fishery, which is operated principally on grounds within the Gulf of Suez; but also on grounds adjacent to the entrance of the Gulf, and in Egyptian and Sudanese waters adjacent to Foul Bay.

Included in the report, is a description of the IT.Dnthly catches landed during each season by in1portant species, the associated fishing efforts, catches per unit effort, and fishing locations. Data interpretation has been limited to general corrr:Bnts only, with the intention that the rrore detailed interpretation would be provided in subsequent reports dealing with stock assessn:ents and managenent.

2. BRIEF DESCRIPTION OF THE FISHERY

Sane 84 vessels are engaged in the fishery; eleven of v.hich are required to be exclusively operated outside the Gulf of Suez. 'The t\ro landing sites are Atal{a, v.hich is adjacent to Suez, and Sakkala within the township of Hurghada. The vessels based at Atalrn are operated within and outside the Gulf, while the vessels based at Sakkala are operated outside the Gulf.

'The fishery is seasonal, particularly that part within the Gulf of Suez, and generally canr.ences in October or NovenJber and concludes at the end of 1lay. All fishing ceases during an approximately ten-day period each rronth, when the IT.Don is full. 'Il1is is a consequence of the fishing rrethod in \vhich the purse seines are set at night around lighted dinghies. Each such dinghy is equipped with about nine kerosene larr;ps each of about 100 watt candle povvBr. This illumination acts to concentrate the fish prior to setting the net.

At the beginning of each season, in respect to the Gulf of Suez fishery, nnst fishing is undertalrnn relatively close to the landing site of Atalrn, and involves fishing trips of twJ to five d:.1.ys duration. Later in the season, trips of longer duration are n:ore conmon. When operating in Foul Bay, a single trip may take as long as twenty days, including SL'<: days travelling to and fran the fishing ground • Trips to Foul Bay may involve a vessel being used for trawling and other nethods, as vvBll as for purse seining. 2

The length of the vessels used range from 12.5 metre to 30 nietre. They are powered by engines of between 100 HP to 400 HP. 'lne nets, v.b.ich are generally 200 to 300 metre in length and 50 to 80 metre in depth, are hauled manually. As a consequence the crew nurrbers are generally high, usually some 25 to 30 persons. Typically two or three shots are undertaken from each vessel during each night of fishing; one shot around each independently placed 'lighted' dinghy.

A nDre detailed general description of the fishery is given in Awadallah (1982), v.b.ich also contains a detailed account of the incomes and costs associated with purse seining during 1980-81.

3 • S'IlJDY METHODS The data presented in this report derives fran two seperate activities. The first of these, the collection of catch statistics, ~as in operation prior to the conmencement of the study; and involves enunierators employed by tte Suez and Hurghada branches of the Department of Agriculture. In respect of each fishing day they record the number of boxes of fish loaded in each species group category, for each vessel. (These numbers of boxes were subsequently converted to catch weights, on the basis of 25 kg/box). Independent records on vessel .!nnvements' kept by the Coastguard were also used, when required, to determine v,hether the fishing had been undertaken within the Gulf of Suez, adjacent to the Gulf, or within or near Foul Bay. The second activity involved the study personnel interviewing a sample of skippers at the landing sites to determine fishing locations and fishing efforts. Interviews were conducted on several days each week. The numbers of samples taken during each nnnth is shown in Table 1 ;¥- The skippers chosen were from those landing catches on the day of interview, and the information collected was that relevent to the nnst recent fishing trip. The locations were provided with reference to place nanies, and aided by the availability of diagrams copied from Admiralty Charts. The inforrnation sought concerning fishing efforts were the number of fishing days, niean number of shots per fishing day,niean nunber of hours from th2 cormiencement of illumination to the tline of the first shot, mean number of lighted lamps used each fishing day, length of net and depth of net. 'Ihe associated information collected ~Bre the names of the skipper and vessel, the nurrber of crew, the nan-ie of the port of landing, and the date. The nwriber of boxes for each species group comprising the particular landings, were subsequently obtained from the previously mentioned catch statistics. Estimates of the total efforts expended during each nnnth \Vere detennined from these sample data. The estin:ation procedure firstly involved determining the fleet effort on each interview day. 'Ihis was estimated as the proc..1uct of the effort associated with the interview landing and the raising factor catch landed by fleet on interview day/catch landed from interview vessel(s)

* The intensity of samples, as percentages of the estimated nurnbers of fishing trips were 3% for th Gulf of Suez, 33% for Foul Bay a..11d adjacent waters, and 2('f'h for adjacent to the Gulf of Suez. 3

1 on the same day • After surrming the fleet effort for all the interview days, the fleet effort for the rronth was determined as the product of this and the raising factor 'catch landed by fleet during ITDnth/catch landed by fleet on interview days'.

Efforts in units of numbers of fishing days, shots, illumination hours, and landings were determined in this way for each ITDnth, and then Sl.lIIm2d to obtain the annual totals. These values were in turn used for estimating the rrean number of shots per fishing day, the rrean number of illumination hours per fishing day and the mean number of fishing days per landing.

The other effort associated statistics such as the mean length of vessels, rrean main engine horse pov.er, rrean length of net , mean depth of net, mean number of lighted lamps used per fishing day, and the rrean number of crew per trip were determined for each month as the simple mean of data resulting directly fran the interviews. The annual means w::re estimated from the rronthly means after 'weighting' each of these by the number of interviews undertaken during the month. The estimation of catches per unit effort involved dividing the monthly and annual landings for each species group by the associated estimated efforts. In respect to the small number of vessels engaged in other types of fishing activity, such as trawling or lining, that part of the landings reslllting fran these other rrethods and the associated fishing efforts, have been excluded when making the above rrentioned calculations. Consequently, the data included in the tables within the report relate exclusively to the activity of purse seining.

4. RESULTS AND D~SCUSSION

Catches The landings in each rronth during the three years, by :important species group are shown in Tab1es 2, 3 . and 4 in respect to the Gulf of Suez; Tables 5, 6, 7 and 8 in respect to Foul Bay and adjacent waters; and Tables 9, 10, 11 and 12 for adjacent to the Gulf of Suez. The species groups considered to be of lesser importance, have been grouped in the 'others 1 category. The '~il:iscellaneous 1 category refers to the unsorted portion of the catches landed. The annual catches from the Gulf of Suez are shown as 14404 tonne(1979/ 80), 9652 tonne (1980/81) and 9290 tonne (1981/82). The ITDst productive ITDnths occured at the beginning of each season, when both the stock abundance and fishing effort are re1atively high. Approximately 65 percent of the annual landings were made during tte first three rronths of each season. The landings during the mid-season ITDnths were generally about a third of that prevailing at the beginning of the season; declining further to a quarter or less by the end of the season. 4

The daninant speciesf grouws ~were the horse macl-cerels and scads (around 50 to 60 percent; and principally Trachurus indicus and Decapterus maruadsi), the round herring (around 20 to 40 percent; and principally Etrwneus teres), and the sardinellas(around 5 to 10 percent; and principally Sardinella gibbosa). The proportion of round herring was substantially less for 1981/ 82, while the sardinellas became progressively rrore important during the three year period.

The annual landings from within and adjacent to Foul Bay were 2854 ton.ri.e (1980), 2815 tonne (1981) and 1953 tonne (1982); and hence contributed sonB 20 percent of the total purse seine catch from the three fishing grounds combined. In contrast to the Gulf of SUez, the quantity of catch landed in each m::mth generally remained constant throughout each season. This \vas in part a consequence of the fishing effort generally increasing at the end of each season.

The dominant species groups were also quite different from the Gulf of SUez; being the spotted sardinella (around 45 to 50 percent; and prin cipally Sardinella sirm), the Indian mackerel (around 10 to 20 percent; and principally RastrelTiger kanagurta), the gold.stripe sardinella (around 10 to 20 percent, and principally Sardinella gibbosa), and the horse nia.ckerels and scads (around 10 percent; and principally D3capterus rnaruadsi). Trachurus indicus and Etrumeus teres, the rrost abundant species in the Gulf of SUez catches by purse seine, were an insignificant component of the landings.

The annual landings from adjacent to the G'ulf of SUez were 75 tonne (1980), 3·18 tonne (1981) and 286 tonne (1982). This 1-vas less than 2 percent of the total catch landed from the three fishing grounds combined. wring each of these seasons the ITDnthly landings varied erratically; with the highest recording being 171 tonne.

The dominant species groups were the horse mackerels and scads (around 30 percent; and principallyTrachurus indicus and Decapterus rnaruadsi), the Indian mackerel (around 20 percent; and principally P..astrelliger kanagurta), the round herring (around 5 to 20 percent; and principally Etrunieus teres), the spotted sardinella (around 5 to 10 percent; and principally Sardinella sirrJ), and the goldstrj pe sardinella (around 5 to 20 percent; and principally sarciinella gibbosa).

The fishing efforts and related statistics for each nnnth during the three years, are shmvn in Tables 13, 14 and 15 in respect to the Gulf of Ei'uez; Tables 16, 17, 18 and 19 in respect to the grounds within and adjacent to Foul Bay; and Tables 20, 21, 22, and 23 for the grounds adjacent to the Gulf of Suez.

In respect to the Gulf of SUez the annual numbers of fishing days were 7901 (1979/80), 8133 (1980/81) and 5790 (1981/82); \vhile the total number of net shots in each year were 22565 (1979/80), 23531 (1980/81), and 17181 (1981/ 82).

The lower effort in 1981/8 2 \vas associated with an administrative decision to delay the conrnencem=nt of the fishing season in that year. 5

1he effort expended in each nnnth can be seen to have declined alnnst progressively during each season. 1he effort during the end of season nnnths was typically sorne 25 percent or less of that at the beginning.

In respect to the effort related statistics, the nurrbers of shots per fishing day were typically close to 3 for all rronths; and the numbers of illumination hours per fishing day were typically close to 7. 1he nun:bers of fishing days associated with each landing generally increased during the fishing seasons, from around 2 to 3 at the beginning to around 4 to 6 at the end. This increase is presumed to have been associated with the desire of skippers to maintain the quantities of catch resulting from each trip, in spite of declining stock abundance occurring throughout each season. In a similar way, the lower nurrber of fishing days per landing during 1979/80, is presumed to have resulted from a generally higher stock abundance, \\hen compared with the other two years.

Vessel lengths and main engine horse powers \vere detenr.ined as cons tant during the period, at around 20 to 25 rretrc:: length and 200 HP. Net lengths and depths were also generally constant, being about 250 to 270 rretre and 65 to 80 metre respectively.

Coincidentally, the numbers of lights used per fishing day and the nurrbers of crew employed during each trip were each about 25. In respect to the fishing efforts for the grounds within and adjacent to Foul Bay, the annual nun:bers of fishing days were 1485 (1980), 1788 (1981) and 1405 (1982); \vhile the total nwrber of net shots in each year were 4077 (1980), 5111 (1981) and 3841 (1982). Efforts were generally higher for the end-of-season nDnths. 1his is believed to be the consequence of vessels being diverted from the Gulf of Suez grounds, in the expectation of greater catching success from the Foul Bay and adjacent grounds at that time of year.

In respect to the effort related statistics, the results are generally very similar -to those for the Gulf of Suez. 1he nun:bers of shots per fishing day were typically close to 3 for all nDnths, and the numbers of illumination hours per fishing day were generally around 6 or 7. '111e numbers of fishing days per landing were substantially greater, hrnvever, at around 11. This preSlllrrlbly relates to the large distance from the fishing grounds to the landing sites, and the desire of skippers to mini!!lise travelling time. Vessel lengths and main engine horse powers were generally constant throughout the period, at around 25 rretre length and 200 to 250 HP respec tively. Net lengths and depths were about 250 metre. and 65 mett".e ; while the nwrbers of lights used per fishing day and the murbers of crew employed during each trip were around 25. 6

In respect to the fishing efforts for the grounds adjacent to the Gulf of Suez, the annual m.mbers of fishing days were 70 · (1980), ~14 (1981) and 400 (1982); vvhile the total nurrber of net shots were 187 (1980),725 (1981) and 1026 (1982). Asnuch of tlie landings from this ground are fran vessels also able to be used within the Gulf of Suez, this increase during the period is preSWJEd to be linked with the lower production fran the Gulf during the latter two years.

Monthly fishing efforts varied erratically throughout each season, although the efforts for the end-of-season rronths were generally higher than for the earlier nxmths. As co1m.ented earlier with respect to the grounds within and adjacent to Foul Bay, this is believed to result from the vessels being diverted out of the Gulf of Suez as a consequence of lov.er stock abundances within the Gulf at these tinl3s.

The effort related statistics are generally similar to those for the other two grounds. The nunbers of shots per fishing day were behveen 2 and 3, and the nurrbers of illurnination hours per fishing day around 6 and 7. The nunbers of fishing days per landing were usually less than 5. Vessel lengths and main engine horse powers were around 20 net re and between 150 and 200 HP respectively. Net lengths and depths were around 200 to 250 nEtr.e and around 65 rretce..; While the nunbers of lights used per fishing day and the nunbers of crew employed during each trip were each around 20 to 30.

'lne catch weights per unit fishing effort, by important species groups, are shown in Tables 24, 25 and 26 in respect to the Gulf of Suez; Tables 27, 28, 29 and 30 in respect to the grounds within and adjacent to Foul Bay; and Tables 31, 32, 33 and 34 for the grounds adjacent to the Gulf of Suez.

The catch weights per unit effort v.hich most clearly reflect the abundance of stock are 'catch/fishini:!; day' and 'catch/shot'. The annual means for these in respect to the Gulf of Suez grounds and all species groups conbined are 1823 kg ( 1979/80), 1187 kg (1980/81) and 1605 kg (1981/82) for the fonner, and 638 kg (1979/80) 410 kg (1980/81) and 541 kg (1981/82) for the latter. Presumably the stock was rrost abundant during the first year and least abundant during the second. The 'catch/landing' Which remained at around 5 tonne for each year \vas judged as more closely reflecting the 'storage' capacity of the vessels, rather than stock abundance.

'Il1e nnnthly catch weights per unit effort can be generally seen to decline during the course of each fishing season; presumably reflecting a decline in the abundance of fish stock. This trend is rrost noticeable in respect to the round herring, for Which the rronthly catch weight per unit 1 effort (in units of'catch j fishing day and'catch/shot) at mid-season is typically around 25 percent of that at the beginning of the season. The trend is least noticeable in respect to the horse mackerels and scads. 7

'Ihe catch weights per unit effort for the grounds within and adjacent to Foul Bay are sanewha t similar to those for the Gulf of Suez. This may reflect similar productivities. The annual means in respect to the species groups canbined for the 'catch /fishing day' and the 'catch j · shot', are 1922 kg (1980), 1Q74 kg (1981) and 1390 kg (1982) in respect to the former, and 700 kg (1980), 551 kg (1981) and 508 kg (1982) for the latter. It appears that stock abundance declined slightly during the three year period. The 'catch/landing' ranged between 15 and 25 tonne ; which is some three to five tin~s greater than for the vessels operated in the Gulf of Suez.

The m::mthly catch weights per unit effort were reasonably constant during each season, which is in substantial contrast to the situation in the Gulf of Suez. It is unclear whether this is because the catches are a negligible portion of the stock, or is due to the within season recruitment of new stock crnlpensating for the rennvals from fishing etc; possibly both factors are involved. Slightly higher catch weights per unit effort can be noted at mid-season for sorre of the species grcups; particularly during 1981/82.

The catch weights per fishing effort for the grounds adjacent to the Gulf of Suez can be seen to be generally lo\ver than for the Gulf. In res pect to the species groups coflbined, the'catch/fishing day' and the 'catch/ shot' are 1n73 kg ( 198 0), 1108 kg (1981), and 71f) kg (198 2) for the fonner, and 401 kg (1980), 480 kg (1981) and 279 kg (1982) for the latter. The 'catch/landing' ranged fairly widely around 4 tonne . There appears to be no trend in the rr.onthly catch weights per unit effort within each season.

The fishing locations identified in relation to the interview landings are shown in Figures 1, 2 and 3 in respect to the Gulf of Suez; Figures 4, 5 and 6 in respect to the grounds within and adjacent to Foul Bay; and Figures 7, 8 and 9 for the grcunds adjacent to the Gulf.

In the Gulf of Suez, the nnst frequented areas appear to have been in the northern half, particularly during the early rronths of each season. Fishing within or adjacent to the shipping channel \\Ould presurr.ably be judged as dangerous. wring the latter part of each season, trips were undertaken to the nnre southern areas, particularly along the eastern shore line. This would contribute to the observed increase in the number of days per fishing trip towards the end of each season.

In respect to the fishing locations within and adjacent to Foul R:'ly, it can be seen that trips into Sudanese v.1aters were frequent. Occasional trips to nnre southern locations are believed to take place. The generally very narrow continental shelf is presuirnd to be in part responsible for the general absence of purse seining between the Gulf of Suez and Fcul Bay. 8

The fishing locations im:rediately adjacent to the Gulf of Suez were in the relatively shallow vvaters on the \vestern side of the entrance; and in the bay adjacent to Safaga. Catches from this ground were generally unloaded at Hurghada.

5. CONCLUDING C0.\1MENTS

On the basis of the inforrr:ation given earlier, it is possible to rmke SOITB very tentative corrments relevent to n:anagement. It seerrs likely, for example, that the pelagic stocks supporting the purse seine fishery within the Gulf of Suez are fully exploited. Accepting that this is so, and assuming the productivities per unit area of the Gulf of Suez ground and the ground within and adjacent to Foul Bay are the san:ie, an estimate of the potential annual catch from the latter ground is given by the product of the mean annual Gulf of Suez catch and the 'area of the ground within and adjacent to Foul Bay/area of the Gulf of Suez ground'.

Revised estirnates of the areas of the two grounds are 4460 km2 for the Gulf of Suez, an~ 1839 km 2 for Foul Bay and adjacent waters (including Sudanese vvaters) • As the mean annual Gulf of Suez catch during the three years was 11115 tonne ; the estinate of the potential annual catch from Foul Bay and adjacent ·waters is 4583 tonne •

The mean annual catch during the three years from the latter ground was 2541 tonne , hence, an estimate of the additional catch likely to result fron.1 'full' exploitation of this ground is 2042 tonne. • Roughly half this potential catch \vould seem to lie in Sudanese vvaters, on the basis that the area of the ground appears to be approximately equally divided between the t\.vo countries.

A similar estimation relevent to the ground irm:iediately adjacent to the Gulf of Suez was undertaken, this time on the basis that the proouctivity per unit area of this ground is son:ie 63 **percent of that for the Gulf of Suez; and the revised estimate for the area of the fonner ground is 652 kn12 * • 'The estimate for the potential annual catch so obtained is 1024 tonne • As the mean annual catch during the three study years was 236 tonne , an esti111ate of the additional catch lil(ely from 'full' exploitation is 788 tonne • This is believed likely to be a considerable over-esU1mtej however, in view of the observation that skippers prefer to a~ploit the ground \vithin anci ci.djacent to Foul Bay, rather than the much closer ground adjacent to the Gulf.

* 'l11ese est:irnates are smie\vhat less than the 6500 km2 for within and inTaedia.tely adjacent to the Gulf of Suez, and the 2000 km 2 for Foul Bay and adjacent waters, given in Sanders and Kedidi ( 1981).
