Guide to Identifying Salmon and Char in the Arctic, Second Edition. By: P. Vecsei*, K. Dunmall, and J. Reist. 24 pages. * Under contract with DFO for First Edition. Contract #F2402-13 105A Above: Pink Salmon, female Mackenzie River, Spawning Phase Cover illustrations: Top: Arctic Char, Kugaaruk, Nunavut, Silver phase Bottom: Chum Salmon, Mackenzie River, Silver phase About this Guide There are many different kinds of salmon and char and many different local names for the same fish. Salmon and char species breed in fresh water but migrate to the sea to feed and grow. The external appearance of the same fish can look different depending on where and when they are harvested. In the sea, maturing salmon and char exhibit a ‘Silver Phase Colour Pattern’ but when in fresh water they can show a ‘Spawning Phase Colour Pattern’. Char can also show a “Silver Phase Colour Pattern” when in fresh water as they may not spawn each year. Salmon are being increasingly harvested in the Canadian Arctic. The numbers, kinds, and locations of salmon being harvested appear to be changing. Therefore, the presence of salmon may be indicating wider changes in the oceans or in the rivers. Monitoring variations in salmon harvest patterns in the Canadian Arctic will help us prepare for and adapt to a future, and perhaps different, Arctic environment. Increasing numbers of salmon may offer the possibility of new fisheries and may also interact with native fishes such as char. These increasing salmon harvests also indicate the need for outreach products to aid local fishers and community members for monitoring purposes. The purposes of this guide are to assist in: 1. Differentiating among Pacific salmon, Atlantic Salmon, and char; 2. Identifying among the different kinds of Pacific salmon; 3. Identifying among the different kinds of char. Printed on waterproof paper; use pencil to make notes. How to Use this Guide Identifying among different kinds of fish can be difficult. There is a great deal of variation in colour patterns, sizes, and shapes within the different species of salmon and char. Therefore, if something does not exactly fit these descriptions or illustrations, it may not be new or different. However, if the fish is unlike anything that is commonly known in that area, please bring it to a Fisheries and Oceans Office for identification. Providing the actual fish to Fisheries and Oceans Canada will: 1) greatly assist in species identification, especially if the fish is difficult to identify; and 2) provide tissue samples for genetic testing to identify species, if necessary. If you have harvested a salmon, please report it to your local Fisheries and Oceans Canada Office with the date and location of capture. This will help research on climate change in the Arctic by documenting changes where salmon are harvested, how many are captured each year, and what kinds of salmon are appearing.

Guidelines for Taking Photographs of Fish for Species Identification It is very difficult to identify a fish to species using a photograph. If you are uncertain about a species of fish, please provide the actual specimen to a DFO office so that the species can be identified and tissue is available for genetic testing to verify species identification, if necessary. If that is not possible, please follow these guidelines and provide the photographs to DFO to assist with species identification. Step 1: Lay the fish on a FLAT SURFACE - ideally the floor – with the left side facing up. If the fish is frozen, put a small amount of water on the side facing up to melt the frost. Step 2: Stand DIRECTLY ABOVE the fish and ZOOM IN so what you want to photograph (i.e., the whole fish, the tail or the head) fills the view from the camera. Step 3: Take a photograph of 1) the whole fish, 2) only the tail, and 3) only the head. Step 4: Please email or bring your 3 photos to your local DFO Office along with the date and location of capture.

  • Do Some Atlantic Bluefin Tuna Skip Spawning?
    SCRS/2006/088 Col. Vol. Sci. Pap. ICCAT, 60(4): 1141-1153 (2007) DO SOME ATLANTIC BLUEFIN TUNA SKIP SPAWNING? David H. Secor1 SUMMARY During the spawning season for Atlantic bluefin tuna, some adults occur outside known spawning centers, suggesting either unknown spawning regions, or fundamental errors in our current understanding of bluefin tuna reproductive schedules. Based upon recent scientific perspectives, skipped spawning (delayed maturation and non-annual spawning) is possibly prevalent in moderately long-lived marine species like bluefin tuna. In principle, skipped spawning represents a trade-off between current and future reproduction. By foregoing reproduction, an individual can incur survival and growth benefits that accrue in deferred reproduction. Across a range of species, skipped reproduction was positively correlated with longevity, but for non-sturgeon species, adults spawned at intervals at least once every two years. A range of types of skipped spawning (constant, younger, older, event skipping; and delays in first maturation) was modeled for the western Atlantic bluefin tuna population to test for their effects on the egg-production-per-recruit biological reference point (stipulated at 20% and 40%). With the exception of extreme delays in maturation, skipped spawning had relatively small effect in depressing fishing mortality (F) threshold values. This was particularly true in comparison to scenarios of a juvenile fishery (ages 4-7), which substantially depressed threshold F values. Indeed, recent F estimates for 1990-2002 western Atlantic bluefin tuna stock assessments were in excess of threshold F values when juvenile size classes were exploited. If western bluefin tuna are currently maturing at an older age than is currently assessed (i.e., 10 v.

  • A Preliminary Study on the Stomach Content of Southern Bluefin Tuna Thunnus Maccoyii Caught by Taiwanese Longliner in the Central Indian Ocean
    CCSBT-ESC/0509/35 A preliminary study on the stomach content of southern bluefin tuna Thunnus maccoyii caught by Taiwanese longliner in the central Indian Ocean Kwang-Ming Liu1, Wei-Ke Chen2, Shoou-Jeng Joung2, and Sui-Kai Chang3 1. Institute of Marine Resource Management, National Taiwan Ocean University, Keelung, Taiwan. 2. Department of Environmental Biology and Fisheries Science, National Taiwan Ocean University, Keelung, Taiwan. 3. Fisheries Agency, Council of Agriculture, Taipei, Taiwan. Abstract The stomach contents of 63 southern bluefin tuna captured by Taiwanese longliners in central Indian Ocean in August 2004 were examined. The size of tunas ranged from 84-187 cm FL (12-115 kg GG). The length and weight frequency distributions indicated that most specimens were in the range of 100-130 cm FL with a body weight between 10 and 30 kg for both sexes. The sexes- combined relationship between dressed weight and fork length can be described by W = 6.975× 10-6× FL3.1765 (n=56, r2=0.967, p < 0.05). The subjective index of fullness of specimens was estimated as: 1 = empty (38.6%), 2 = <half full (47.37%), 3 = half full (3.51%), 4 = >half full (5.26%), and 5 = full (5.26%). For the stomachs with prey items, almost all the preys are pisces and the proportion of each prey groups are fishes (95.6%), cephalopods (2.05%), and crustaceans (0.02%). In total, 6 prey taxa were identified – 4 species of fish, 1 unidentified pisces, 1 unidentified crustacean, and 1 unidentified squid. The 4 fish species fall in the family of Carangidae, Clupeidae, Emmelichthyidae, and Hemiramphidae.

    DISEASES OF AQUATIC ORGANISMS Vol. 4: 165-168, 1988 Published July 27 Dis. aquat. Org. I Oral administration of Fumagillin DCH protects chinook salmon Oncorhynchus tsha wytscha from experimentally-induced proliferative kidney disease R. P. Hedrick*,J. M. Groff, P. Foley, T. McDowell Aquaculture and Fisheries Program, Department of Medicine, School of Veterinary Medicine, University of California, Davis, California 95616, USA ABSTRACT: The antibiotic Fumagillin DCH was found to be effective in controlling experimental infections with PKX, the myxosporean that causes proliferative kidney disease (PKD) in salmonid fish. Following 6 or 7 wk of treatment, experimentally infected chinook salmon Oncorhynchus tshawytscha showed no evidence of PKX cells, or of the renal inflammation characteristic of PKD, on withdrawal of the treatment and tor up to 7 wk afterwards. In contrast, 90 to 100 % of fish (in 2 experiments) that were injected with PKX, but not glven the antibiotic, had numerous PKX cells in the kidney and developed clinical PKD. This is the first report of an effective orally administered drug for the control of a myxozoan infection in salmonid fish.
