Characteristics of Fall Chum Salmon Spawning Habitat on a Mainstem River in Interior Alaska. By Sean E. Burril, Christian E. Zimmerman, and James E. Finn.

Collections. Collections consisted of summer chum salmon from HC and SJF subpopulations (Fig. 1; Table 1).Tissue samples for this study were collected from spawners in seven rivers and creeks in HC and two creeks in SJF from through (Table 1).Samples collected prior to initiating supplementation programs were termed ‘original’ and samples collected after supplementation fish. in and The migration of juvenile chum salmon peaked in mid-May and catch rates were greatest when water levels were rising. Movement of chum salmon was diurnal with highest catch rates occurring during the hours of low light (that is, to ). Trap efficiency ranged from to percent (overall efficiency = percent).
English: This movie shows the spawning behavior and gamete release of chum salmon. The female was attached with an electrocardiogram (ECG) data logger and injected with Salmon Ringer solution (QuickTime; MB). Date: Source: Movie S1 from Makiguchi Y, Nagata S, Kojima T, Ichimura M, Konno Y, Murata H, Ueda H (). Chum salmon in ocean coloration are metallic greenish-blue on the dorsal surface with fine black speckles making them difficult to distinguish from sockeye salmon. Chum salmon have fewer (), shorter and heavier gill rakers on the first arch, relatively large eyes, a very narrow caudal peduncle (base of the tail), and deeply forked caudal fin.

Adult pink salmon (Oncorhynchus gorbuscha) and coho salmon (Oncorhynchus kisutch) were held in freshwater, seawater (28–32%%.), and in an estuary (24–31‰ with a low-salinity surface lens) to determine the effects of salinity on survival to spawning and gamete viability.
Gamete viability was determined by individual by: Under conditions similar to those employed here, we conclude for chum salmon gametes that: (1) stored gametes should be cooled (3) to prolong viability (i.e., up to h before a significant loss in viability would be expected with stored eggs); (2) egg and milt storage should not exceed 12 h at storage temperatures of 15'C or greater, since the lower 95% confidence limit for time to 90% FS for SYY X Cited by: reduced returns of adult Chinook salmon in Big Creek (a tributary of the Middle Fork Salmon River).
In subsequent years, a more comprehensive gene banking effort was initiated (Faurot et al. ) including collections from additional Chinook salmon and steelhead populations in the Snake River basin (Armstrong and Kucera ).

Trout and Salmon of North America By Robert J. Behnke, George Scott (Editor), Joseph R. Tomelleri (Illustrator), and Thomas McGuane, Hardcover, pages. This new book is an authoritative, easy-to-use guide to all types of trout and salmon of North America. This pilot study examined five commercial salmon feeds, four farmed salmon (one Atlantic, three chinooks) and four wild salmon (one chinook, one chum, two sockeyes) from the Pacific Coast for PCBs ( congeners), polybrominated diphenylethers (PBDEs – 41 congeners), 25 organochlorine pesticides (OPs), 20 polycyclic aromatic hydrocarbons (PAHs), and methyl and inorganic mercury.

Under practical conditions it is unlikely that the rinsing procedure would last 30 min. While buffered NaC1 begins affecting fertility after 30 min it was previously found that ova from coho and chum salmon 81 TABLE I Fertility of coho salmon eggs with various ratios of broken ova per batch.

Chum salmon often spawn in small side channels and other areas of large rivers where upwelling springs provide excellent conditions for egg survival. They also spawn in many of the same places as do pink salmon, i.e., small streams and intertidal zones. Some chum in.
Some studies present DMSO as the best option for either zebrafish blastomere vitrification (Cardona-Costa and Garcia-Ximenez, ) or chum salmon blastomere cryopreservation (Kusuda et al., ). Interestingly, the addition of an antifreeze protein originating from fish, AFP type I, has significantly improved zebrafish blastomere survival.
Chum Salmon 1 Oncorhynchus keta s pawning chum salmon are dark olive on the back and dark maroon on the sides with irregular greenish vertical bars on the sides and no spots on the tail.

As the adults used in our study were reared in a common hatchery environment, and as salmon from the Namsen were the main ancestral population to the Aquagen strain (Gjedrem et al.
; Garant et al. ), we can reject the hypotheses that relaxed selection, directed domestication and/or reduced genetic variation have led to any changes in. In this study, we examined the causes of the observed growth difference of adult chum salmon using a bioenergetics model coupled with the output from the 3-D NEMURO model (NEMURO coupled with three dimensional physical global model, Aita et al., ).
We also discuss the effect of water temperature increase on chum. In the warming Arctic, aquatic habitats are in flux and salmon are exploring their options.
Adult Pacific salmon, including sockeye (Oncorhynchus nerka), coho (O. kisutch), Chinook (O. tshawytscha), pink (O. gorbuscha) and chum (O. keta) have been captured throughout the Arctic.
Pink and chum salmon are the most common species found in the Arctic today. Also, closely related species can express different stress levels at similar exposures, e.g., chum salmon (O.
keta) fry exposed to suspended sediment concentrations of 28 and 55 g/L resulted in 50 % mortality after 96 h (Smith ), whereas the same mortality rate was expressed at lower concentrations –35 g/L over the same duration for.Chum Salmon AKA: calico salmon, dog salmon, fall salmon, autumn salmon, chum, keta; French: saumon keta; Japanese: sake, shake.
