Factors affecting post-release survival of coded-wire tagged Lake Trout Salvelinus namaycush in Lake Michigan at four historical spawning locations

Since the 1950s, fishery agencies on Lake Michigan have pursued Lake Trout Salvelinus namaycush rehabilitation through Sea Lamprey Petromyzon marinus control, harvest regulations, and by stocking millions of fish annually. Stocking was prioritized at four historically important spawning locations beginning in 1985, and coded wire tags (CWTs) were...

Growth and energy budget of Northern Snakehead Channa argus in relation to ration

Northern Snakehead Channa argus weighing 188.54+13.80 g were fed live Oriental Weatherfish Misgurnus anguillicaudatus at five rations (starvation, 1, 2, 4% body weight per day and satiation) at 28 oC under laboratory conditions to determine its growth and energy budget in relation to ration. The specific growth rate increased linearly with...
