Effects of Introduced Alabama Bass on an Existing Largemouth Bass Fishery in Moss Lake, North Carolina

SEAFWA Journal Volume 10, March 2023

Negative impacts from non-native congener introductions have emerged as an immediate threat to black bass conservation and management. Largemouth bass (Micropterus salmoides) historically comprised the sole black bass fishery in Moss Lake, North Carolina. Alabama bass (Micropterus henshalli) were illegally introduced into Moss Lake and were first detected during a 2008 electrofishing survey conducted by North Carolina Wildlife Resources Commission biologists. Since this detection, Alabama bass rapidly increased in abundance throughout the reservoir...

Sportfish Population Characteristics Following Mechanical Largemouth Bass Removal in Two Small Public Fishing Impoundments in South Carolina

SEAFWA Journal Volume 10, March 2023

Declining angler harvest rates of largemouth bass (Micropterus salmoides) have increasingly led to small impoundments containing over-crowded largemouth bass populations. Various methods to correct or prevent crowded largemouth bass populations have been used by fisheries man- agers, with mixed results. We removed largemouth bass from two small impoundments in South Carolina using boat electrofishing over two consecu- tive years, with targets of removing 40–50% of the largemouth bass populations each year. We used relative weight (Wr) as the removal criterion,...

Increasing Largemouth Bass Carrying Capacity Using Destratification: A Case Study

SEAFWA Journal Volume 6, March 2019

Aeration can circulate waters by disrupting thermal density differences associated with stratification, allowing homogenization of tempera- ture, oxygen, and other physicochemical characteristics within the water body. Use of lake and pond destratification as a management tool has been increasing in recent years, yet data are limited regarding its effects on fish communities. This case study examines the response of a largemouth bass (Micropterus salmoides) population to destratification in a 2.4-ha pond over nearly a decade. Biomass (35.8–42.8 kg ha–1) and density (51–93 fish ha–1) of...

Stocking Threadfin Shad to Enhance Largemouth Bass Populations in Two Alabama Ponds

SEAFWA Journal Volume 2, March 2015

Increasingly, new innovative management approaches are being used in small ponds that contain largemouth bass (Micropterus salmoides) and bluegill (Lepomis macrochirus) to increase the quality of largemouth bass fisheries. One approach is to stock additional forage fish. Threadfin shad (Dorosoma petenense) were stocked into two small Alabama ponds (1.9 and 5.3 ha) in 2007, 4 yrs after renovation and restocking with largemouth bass and bluegill (1:15 stocking ratio) to improve largemouth bass relative weight (Wr) and length distributions. Threadfin shad inhabited these two ponds for about 2...
