Angler Awareness and Acceptance of a Mandatory Crappie Harvest Regulation at Lake Fork Reservoir, Texas

To reduce mortality of crappie Pomoxis spp. caught from deep water in winter, beginning in 1991 the Texas Parks and Wildlife Department (TPWD) replaced the statewide 254-mm minimum length limit for crappie with a mandatory harvest regulation during December through February on Lake Fork Reservoir. The special regulation required anglers to harvest the first 25 crappie, regardless of size, with no catch-and-release or culling. Anglers (364 parties, 750 anglers) seeking crappie were asked questions regarding their awareness, their acceptance and how they learned of the regulation during...

Effects Of Temperature On Survival Of Peacock Bass Fingerlings

Effects of temperature on survival of peacock bass ( Cichla ocellaris) fingerlings were examined in the laboratory. Fish were acclimated to 25, 30 or 35 C prior to testing. The ultimate lower and upper lethal temperatures in freshwater were 15.6 and 37.9 C when the temperature change from acclimation was I C/ day. Salinity (10% 0) significantly reduced (P<0.05) the ultimate lower lethal temperature to 14.4 C. Acclimation temperature significantly affected the temperature at which peacock bass began losing equilibrium (LEso) and dying (CTMin) when fish were exposed to a I Cf h decrease....
