Investigating the link between stress, temperature, and metabolic inertia in largemouth bass

Postby WB Staff » Fri Feb 02, 2018 12:08 am

Temperature is an important factor in fish survival. Temperature can affect where a fish lives,
how quickly it responds to physiological factors, and the rate of metabolic processes. Stress is a
common physiological response when fish are exposed to handling practices in hatcheries and
angling by the public and by professionals in tournaments. Temperature and stress response
research is vital in order to support fish survival, especially in hatcheries and tournaments where
fish survival is of the utmost importance

This study looks at the relationship between handling
stress typical of hatcheries or anglers and a temperature drop similar to what could occur in
livewells or acclimation tanks on the metabolic inertia of largemouth bass Micropterus
salmoides. Largemouth bass are often raised in hatcheries or caught by anglers and so were ideal
for this study. We will look at the effect of handling stress and a 4°C drop in temperature on
largemouth bass metabolic rate in order to determine how long it takes the fish to recover.
