Shoal bass life history and threats: a synthesis of current knowledge of a Micropterus species

Abstract

The shoal bass (Micropterus cataractae) is a black bass species native to the Apalachicola-Chattahoochee-Flint Basin of the southeastern U.S. Damming in the basin has created extensive habitat loss; consequently, shoal bass have been extirpated from several areas of their native range. Early shoal bass research focused on age and growth, spawning habits, and distribution. The formal recognition of the species in 1999 increased interest in research and restoration. Recent research has described critical habitat, movements, and systematic information about shoal bass. As researchers continue to investigate the life history of the species, several threats have become apparent including habitat modification, interactions with non-native black basses, and the effects of angling. Currently, management needs include basic population assessments and investigation of factors causing population declines. Despite increased interest in the species, the outlook for the long-term conservation of the shoal bass is uncertain.
