Contribution of Largemouth Bass Reared in Nursery Ponds to Year Classes in Two Texas Reservoirs

Genetically-marked Florida largemouth bass (Micropterus salmoides floridanus) fingerlings with rare or unique genotypes were stocked into nursery ponds at Lake Conroe (8,484 ha) and Lake Gladewater (323 ha). Following grow-out, advancedsize individuals were stocked into respective reservoirs. We measured the contribution of stocked individuals to corresponding year classes in receiving reservoirs. Largemouth bass survival in nursery ponds at the end of the grow-out period was 15.6% at Lake Conroe and 20.9% at Lake Gladewater. A total of 2.8 fish/ha (mean total length = 138 mm) were stocked...

Management Application of Angler Recognition Program Data

Infonnation from applications to 2 angler recognition programs administered by the Texas Parks and Wildlife Department were analyzed to determine changes in the number and weight of fish submitted each year. Frequent increases in largemouth bass (Micropterus salmoides) (5 in a 6-year time span), striped bass (Morone saxatilis) (9 in a 14-year time span), and hybrid striped bass (M. chrysops X M. saxatilis) (7 in 8-year time span) state records were documented. Significant annual increases in mean weight of largemouth bass (4.0 kg in 1974 to >5.0 kg in 1986 and 1987) and smallmouth bass...

Attended and Unattended Yo-yo Fishing Catch and Mortality

Yo-yo catch and mortality of caught fish were evaluated at Caddo Lake, Texas, using attended (checked at least once each hour) and unattended fishing techniques. A total of 400 yo-yos (200 attended and 200 unattended) were fished 3,991.75 hours during February and March. Ten species were caught; black crappie (Pomoxis nigromaculatus) and yellow bullhead (Ictalurus natalis) comprised 54% and 20% of the catch, respectively. Catch rates were significantly higher for attended sets (0.12 fish/yo-yo hour) than unattended sets (0.03 fish/yo-yo hour). Unattended sets resulted in high mortality (85...
