| Fingerling Production in Ponds Fingerling culture ponds are usually smaller than ponds used for grow out. The advantages to this practice, as well as food, water quality and harvesting requirements, are outlined in this publication. |
| Stocking Crawfish Ponds: 2005 Recommendations Existing ponds normally do not need to be restocked. New ponds require 50-60 pounds per acre of mature crawfish. Drain ponds 2-3 weeks after stocking to allow time for crawfish to burrow into the ground. |
| Cryopreservation: A New Industry for Aquatic Species The aquaculture industry is looking increasingly to genetic improvement for gains in production. But improving the genetics of aquatic species can take a long time. With catfish, for instance, a male typically spawns with only one female each season. Even if genetically superior males and females could be identified, the process of developing breeding stock and improved lines could take a decade or more. |
| Pet Turtle Production Turtle farming has been practiced for decades in Louisiana. The industry developed to produce baby turtles, specifically red-earsliders (Trachemys scripta elegans),for sale as pets. This publication reviews commonly used production and marketing techniques. |
| Crawfish News June 2010 (Vol 3, No 4) Topics covered include when to cease harvesting and when to drain ponds, planting crawfish forages, liming of crawfish ponds, the importance of record keeping and a brief review of crawfish burrow ecology. |
