摘要:Abstract(#br)Nonlethal tools (plasma sex steroid concentrations and ultrasound) for assigning sex and reproductive condition in Burbot Lota lota from Lake Roosevelt, Washington, were assessed. Gonadal tissue, blood plasma, and gonadal sonograms were collected monthly from No...

摘要:Abstract(#br)Delineating population structure helps fishery managers to maintain a diverse “portfolio” of local spawning populations (stocks), as well as facilitate stock‐specific management. In Lake Erie, commercial and recreational fisheries for Walleye Sander vitreus...

摘要:Abstract(#br)Forage fishes have a cosmopolitan distribution and constitute key species in marine trophic webs throughout the world. We estimated the energy density of the Argentine Anchovy Engraulis anchoita , a key component of the base of the food web in a large fraction o...

摘要:Abstract(#br)The South Fork Snake River supports one of the few remaining robust populations of fluvial Yellowstone Cutthroat Trout Oncorhynchus clarkii bouvieri in Idaho. Since the early to mid‐2000s, salmonid populations on the South Fork Snake River have been intensively ...

摘要:Abstract(#br)Physiological condition (hereafter shortened to “condition”) influences survival, spawning schedules, and reproductive effort in salmonids. In iteroparous females, the effects of first spawning on condition could result in trade‐offs with future reproductio...

摘要:Abstract(#br)Despite the importance of straying in understanding the ecology of Pacific salmon Oncorhynchus spp. and steelhead O. mykiss , most of what is known about salmon and steelhead straying comes from tagged hatchery fish. We provide estimates of donor straying by nat...

摘要:Abstract(#br)Several species of ciscoes Coregonus , subgenus Leucichthys that are native to the Laurentian Great Lakes are rare or extirpated. The restoration of Coregonus fishes is being actively pursued through stocking, and success may depend on the availability of unoccu...

摘要:Abstract(#br)In recreational fisheries it is understood that individual fish that exhibit bolder personality traits have a tendency to be removed from the population (i.e., fishing mortality via harvest or catch‐and‐release mortality), while more timid individuals remain. Th...
