Aggressive distance in juvenile coho salmon (Oncorhynchus kisutch)
DILL, L. M. 1978. Aggress~ve distance in juvenile coho salmon (Oncorhynchus kisutch). Can. J . Zool. 56: 14411446. The distances from which resident coho salmon approached, charged, or gave lateral displays to inhuders were recorded, as were rhe npproach and charge velocities. Ench of five residents was terted while under rhree Feeding t e ~ i m e ~ . and In response to three sizes of intnzder ...
متن کاملSexual difference in PCB concentrations of coho salmon (Oncorhynchus kisutch).
We determined polychlorinated biphenyl (PCB) concentrations in 35 female coho salmon (Oncorhynchus kisutch) and 60 male coho salmon caught in Lake Michigan (Michigan and Wisconsin, United States) during the fall of 1994 and 1995. In addition, we determined PCB concentrations in the skin-on fillets of 26 female and 19 male Lake Michigan coho salmon caught during the fall of 2004 and 2006. All co...
متن کاملCoho Salmon (Oncorhynchus kisutch) fry population dynamics in Carnation Creek
Salmon are keystone species to multiple environments and are heavily relied upon by many different organisms. This study compares the populations of rearing Coho salmon fry (Oncorhynchus kisutch) at pre-established sampling sections of Carnation Creek. This population data was collected during the summer as part of the more extensive Carnation Creek Watershed study, which is the longest continu...
متن کاملPresent State of Asian Coho Salmon (Oncorhynchus kisutch) Stocks
Data from pelagic trawl surveys by TINRO-center from 1987 to 1996 in the Okhotsk Sea indicate that coho abundance is underestimated by coastal observations. The approximate Asian coho spawning biomass is 7,300-16,000 tons for the 1990s. Ways of improving Asian coho salmon resource management are discussed. Collection of precise fishery and escapement statistics must be expanded in areas previou...
متن کاملOntogenetic changes in photoreceptor opsin gene expression in coho salmon (Oncorhynchus kisutch, Walbaum).
Pacific salmonids start life in fresh water then migrate to the sea, after a metamorphic event called smoltification, later returning to their natal freshwater streams to spawn and die. To accommodate changes in visual environments throughout life history, salmon may adjust their spectral sensitivity. We investigated this possibility by examining ontogenetic and thyroid hormone (TH)-induced cha...
