This document is the Glossary in the Louisiana Crawfish Production Manual. Crawfish Biology [Image: This document is Chapter 2 in the Louisiana Crawfish Production Manual. ] Procambarus clarkii (red swamp crawfish) and P. zonangulus (white river crawfish) have similar ecological requirements associated with natural cycles of flooding and drying. Both construct burrows in which they survive and reproduce during temporary dry periods. The highest densities and most complex population structures usually occur where crawfish have been grown in the same location for several consecutive seasons.

Procambarid Crawfish: Life History and Biology [Image: Procambarid crawfish: Life History and Biology] This article discusses the life history and biology of the Procambarid crawfishes, the red swamp crawfish and white river crawfish. Color Variations in the Red Swamp Crawfish [Image: Blue/Red/White Crawfish] Captured "red swamp crawfish" vary widely in color because of their diet and environmental conditions, but the most exotic colors occur because of mutations in the genes that are responsible for pigment formation.  more articles... Effects of Food Limitations On Crawfish Reproduction [Image: Females with young] Limited food resources near the end of the crawfish production season resulted in lower reproduction. Moreover, short-term feeding with high protein/high energy feeds in forage depleted ponds before crawfish burrowing seemed to mitigate the food shortages and even increased the spawning rate over those crawfish from ponds rich in forage. 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.
