The influence of ambient salinity on routine metabolism in the teleost Cyprinodon variegatus Lacepède The influence of ambient salinity on routine metabolism in the teleost Cyprinodon variegatus Lacepède

Routine metabolism of the euryhaline cyprinodontid Cyprinodon variegatus Lacepede was measured at a series of ambient salinities ranging from fresh water through 100‰. Fish used had been sequentially acclimated to the test salinities (ambient temperature of 20±1° C and a 12: 12 L: D schedule). Routine metabolic rates were highest at ambient salinities from 15 to 50‰. Metabolism was...

Evaluation of a mark-recapture method for estimating mortality and migration rates of stratified populations Evaluation of a mark-recapture method for estimating mortality and migration rates of stratified populations

We simulated mark–recapture experiments to evaluate a method for estimating fishing mortality and migration rates of populations stratified at release and recovery. When fish released in two or more strata were recovered from different recapture strata in nearly the same proportions, conditional recapture probabilities were estimated outside the [0, 1] interval. The maximum likelihood...
