Productivity of functional guilds of fishes in managed wetlands in coastal South Carolina
Kelly F. Robinson, Cecil A. Jennings
2014, Journal of Fish and Wildlife Management (5) 70-86
In coastal South Carolina, many wetlands are impounded and managed as migratory waterfowl habitat. Impoundment effects on fish production and habitat quality largely are unknown. We used the size-frequency method to estimate summer production of fish guilds in three impoundments along the Combahee River, South Carolina. We predicted that guild-specific...
