Crawfish Production Manual
Commercial sales of crawfish in Louisiana date back to the late 1800s, and today's crawfish industry includes millions of pounds harvested from farms and natural habitats in the state. This publication covers a wide range of topics on crawfish production, including crawfish biology, pond design, forage management, stocking, water quality, harvesting, marketing and much more.

Crawfish News July 2008
Crawfish News, July 2008 (Vol 1, No 4)
July 2008. This newsletter has information on late-summer planting and management of crawfish forage crops, control measures for fall army worms, a brief overview on crawfish reproduction and an annoucement for an upcoming survey on crawfish production economics.
Responding to Fish Kills
During the summer and early fall, it is not unusual for fish kills to occur in commercial ponds under uncertain circumstances.
Cryopreservation
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.
Chapter 9. Other Management Considerations
Other Management Considerations
This chapter (Chapter 9) from the Louisiana Crawfish Production Manual discusses other management considerations in commercial crawfish farming, including pond flood-up, population management, supplemental feeding, managing ponds for larger crawfish, diseases, predators, nuisance wildlife, control methods and deveoping your business.
Aquaculture BMP
Aquaculture Environmental Best Management Practices
BMPs for aquaculture enterprises are a specific set of practices used by growers to reduce the amount of soil, nutrients, pesticides and microbial contaminants entering surface water and groundwater while maintaining or improving productivity. This BMP manual is a guide for the selection, implementation and management of practices that will help growers conserve soil and protect water and air resources. (PDF format only)

Crawfish News June 2012
Crawfish News June 2012 (Vol 5, No 3)
This newsletter contains information on draining ponds, pond renovation, selecting and planting forages for crawfish, liming crawfish ponds, and the potential effects of using slightly salty water on crawfish forage crops.
Purchasing Catfish Fingerlings
Purchasing Channel Catfish Fingerlings
It is important to purchase the best available catfish fingerlings when stocking commercial production ponds. Poor quality can result in delayed harvesting, underestimated stocking weights and disease transmission to fish already present in the pond. Fingerling quality is judged on grading, strain, health, and the supplier's reliability.

Pump Curve
Reducing Crawfish Pumping Costs
Farming crawfish requires pumping water. Pumping water costs money. Although there is really no way to get around these facts, we can take action to minimize pumping costs.
Crawifsh News April 2012
Crawifsh News April 2012 (Vol 5, No 2)
This newsletter covers stocking recommendations for crawfish, controlling white river crawfish in ponds, recommendations on when to stop trapping, and the estimated 2011 farm-raised and wild crawfish harvest in Louisiana.
A Review of Component Options
A Review of Component Options
Most fish grown in ponds, floating net pens or raceways can be reared in commercial-scale recirculating systems, but the economic feasibility of doing so is not certain. The challenge to designers of recirculating systems is to maximize production capacity per dollar of capital invested.
Crawfish. A Healthy Choice!
Crawfish A Healthy Choice!
This article provides basic nutritional information on crawfish and guidelines for handling and care of live crawfish and crawfish tail-meat products. Several crawfish recipes are included.
Biology and Life History
Red Drum: Biology and Life History
The red drum (Sciaenops ocellatus) is a marine fish that naturally ranges from Central Mexico on the coast of the Gulf of Mexico to Massachusetts on the Atlantic Ocean. Red drum have been taken in small numbers by commercial fishermen on the Atlantic Coast for many years, but the species is important only on the Gulf Coast.
FAQ's
How do I build a pond? Where can I get fish to stock my pond? What do I do about these aquatic weeds? These are all questions that are frequently asked in regards to recreational ponds. This document answers these questions and more.
