The objective of this chapter is to describe some key linkages between the ecology of salmonid fish and the hydrologic and geomorphic features of their spawning streams in British Columbia. Salmonid refers to all species in the Salmonidae family of fishes, which includes Pacific salmon and trout (Oncorhynchus spp.), char (Salvelinus spp.), grayling (Thymallus spp.), whitefish and cisco (Coregon...

in the present study, we reported infection with eighteen species of the genus dactylogyrus, belong to thefamily dactylogyridae from five breeder fish species, including common carp (cyprinus carpio), grass carp(ctenopharyngodon idella), silver carp (hypophthalmichthys molitrix), big head carp (hypophthalmichthysnobilis) and black carp (myelopharyngodon piceus) which introduced and imported to ...

In 1991, the National Marine Fisheries Service, as mandated by the U.S. Driftnet Impact Monitoring,. Assessment, and Control Act of 1987 and U.S. Public Law 101-627, developed methods to estimate the incidental catches (bycatch) of salmonids in the North Pacific squid driftnet fisheries of Japan, the Republic of Korea (ROK), and Taiwan. Two analytical approaches were used for the Japanese fishe...

In the summer of 1998 and 1999, watersheds in western Oregon were randomly sampled for stream habitat conditions. Sites were selected using a random tessellation stratified design. Oregon Department of Fish and Wildlife Aquatic Inventories methods were used to quantify indicators of sediment supply and quality, riparian forest connectivity and health, habitat structure, in-stream complexity, an...

The recently designated cyprinid herpesvirus 3 (CyHV-3) is an emerging agent that causes fatal disease in common and koi carp. Since its emergence in the late 1990s, this highly contagious pathogen has caused severe financial losses in common and koi carp culture industries worldwide. In addition to its economic role, recent studies suggest that CyHV-3 may have a role in fundamental research. C...

Salmonid fishes, native to the northern hemisphere, have become naturalized in many austral countries and appear linked to the decline of native fishes, particularly galaxiids. However, a lack of baseline information and the potential for confounding anthropogenic stressors have led to uncertainty regarding the association between salmonid invasions and galaxiid declines, especially in lakes, a...

2 Assistant Professor of Aquatic Ecology, University of Maryland, Frostburg, Maryland. Abstract: This paper explores the tightness of the linkage between stream-dwelling salmonids and riparian vegetation. Comparison of original distributions of salmonid species with that of vegetation types shows that distribution within a given salmonid species is not limited to a specific vegetation type, and...

During the course of metabolic studies with salmonid fish cell lines, an investigation of the in vitro CO2 requirements of these cells was undertaken . Werkman (13) hypothesized that all forms of life assimilate CO2 and that this essential physiological function is required for the synthesis of indispensable metabolic intermediates. The CO 2 requirement of mammalian cell cultures has been well ...

Large portions of anadromous salmonid habitat in the western United States has been lost because of dams and other blockages. This loss has the potential to affect salmonid evolution through natural selection if the loss is biased, affecting certain types of habitat differentially, and if phenotypic traits correlated with those habitat types are heritable. Habitat loss can also affect salmonid ...
