Largemouth Bass in a Warming World
Rypel, A.L. 2009. Climate-growth relationships for largemouth bass (Micropterus salmoides) across three southeastern USA states. Ecology of Freshwater Fish 18: 620-628.
Rypel reports that "results from multiple regressions suggested that on average roughly 50% of the annual variability in largemouth bass growth was attributable to climatic variations," with annual growth indices typically being found to be "above-average during the warmest, driest years, and below-average during the coldest, wettest years," due to the facts that "annual bass growth was significantly negatively correlated with annual precipitation metrics, and significantly positively correlated with annual temperature metrics."
Considering the above findings, the warming and drying that is predicted by models to occur in many places would appear to be good news for largemouth bass, as well as for the people who love to fish for them and for many other types of fish, since an increase in temperature generally "stimulates metabolism, and enhances growth rates of fishes," according to Rypel, who cites in this regard the studies of Beitinger and Fitzpatrick (1979) and Brander (1995).
