Spawning Habitat Partitioning of Sympatric Salmonid Populations in the Upper Bois Brule River, Wisconsin

Fishes
Spawning habitat partitioning can be important for maintaining sympatric fish species. Likewise, critical spawning habitat loss may challenge the long-term persistence of sympatric fish species.

Salmonids in an Urban Stream: Movement, Habitat, and Potential Barriers

, 2017
Studies on the movement of salmonids in the Pacific Northwest have been vital to their management and recovery. Salmonids can move great distances in search of food, habitat and potential mates, requiring them to travel through a range of different ...

Transcriptomic profiling of gill biopsies to define predictive markers for seawater survival in farmed Atlantic salmon

Journal of Fish Biology, EarlyView.
Abstract Wild Atlantic salmon migrate to sea following completion of a developmental process known as parr‐smolt transformation (PST), which establishes a seawater (SW) tolerant phenotype. Effective imitation of this aspect of anadromous life history is a crucial aspect of commercial salmon production, with current industry practice being marred by ...

Is There Abundant Zooplankton Prey for Salmonids in the Subarctic North Pacific in Winter?

, 1999
Macrozooplankton was sampled using a North Pacific standard plankton net during two trans-Pacific cruises of the R/V Kaiyo maru at 27 and 23 stations in a wide area of the northern North Pacific Ocean in November-December 1992 and January 1996 ...

Upstream Transport of Mirex by Migrating Salmonids

, 1989
Mirex is a persistent chlorinated hydrocarbon found in appreciable concentrations in sediments and pelagic organisms of Lake Ontario. Concentrations are particularly high in introduced salmonids, which spawn in considerable numbers in tributaries of the

Do the biological characteristics of trout (Salmo trutta) smolts influence their spring migration timing and maiden marine sojourn duration?

Journal of Fish Biology, EarlyView.
Abstract Anadromous salmonids migrate seaward to exploit feeding and growth opportunities in marine habitats, yet how smolt biological characteristics influence their marine migratory behavior remains poorly understood. This study used 9 years of trout (Salmo trutta) population monitoring data from 15,595 tagged age‐0+ parr, 1033 smolts detected ...

Successive oral immunizations against Piscirickettsia salmonis and infectious salmon anemia virus are required to maintain a long-term protection in farmed salmonids

Frontiers in Immunology, 2015
Currently, there is a growing demand to determine the protective status of vaccinated fish in order to prevent diseases outbreaks. A set of different parameters that include the infectious and immunological status of vaccinated salmonids from 622 Chilean

Morphometric discrimination of Gyrodactylus salaris Malmberg (Monogenea) from species of Gyrodactylus parasitising British salmonids using novel parameters

, 2001
Morphometric data were collected from scanning electron micrographs of released hamuli and marginal hooks collected from five species and three morphotypes of Gyrodactylus parasitising salmonids in the UK and Canada.
