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.

Fertilization of Fish Ponds
Fertilization of Fish Ponds
When ponds are fertilized, nutrients stimulate the growth of microscopic plants in the water (phytoplankton). Phytoplankton is food for other organisms (zooplankton and larger animals) that are eaten by fish. Abundant growth of these microscopic plants gives water a turbid, greenish color (called a “bloom”) that can prevent light from reaching the pond bottom and reduce the growth of rooted aquatic weeds.
Crawfish News Summer 2010 (Vol 3, No 5)
Crawfish News Summer 2010 (Vol 3, No 5)
This newsletter discusses control of armyworms in late planted crawfish forages, managing wild trash fish in crawfish ponds, the benefits of crawfish ponds as wetland habitat for waterbirds, managing excess water associated with tropical storms and hurricanes, and crawfish legislation passed in the 2010 legislative session.
Production of Fingerlings and Stockers
Red Drum: Production of Fingerlings and Stockers
Production of fingerling and stocker red drum is normally practiced by hatchery producers. At the same time, these are completely different operations and require different areas, practices and expertise. Usually the larvae are secured at an age of about 3 days, and one of two methods of production is used. Only pond culture production methods are presented here.
LSU Pet Turtle Research and Extension Contacts
This list is comprised of contact information for pet turtle experts within the LSU Agricultural Center and the LSU - Baton Rouge campus.
Catfish Production Economics
Catfish Production Economics
The commercial production of catfish in the United States has increased at a phenomenal rate in the last three decades. By 1997, channel catfish culture was the largest aquaculture industry in the United States, with catfish production representing 72 percent (by weight) and 55 percent (by value) of the entire industry (U.S. Joint Subcommittee on Aquaculture 1999).

Aquatic Weed Control
Aquatic weeds are a common problem in recreational ponds. This document discusses aquatic weeds and ways of controling them.
Aquatic Weed Management: Herbicides
Herbicides are just one method of managing aquatic weeds. There are also: 1) preventive methods such as proper pond site selection and construction, fertilization andperiodic draw-downs; 2) biological methods such as grass carp (Ctenopharyngodon idella); and 3) mechanical methods such as cutting, seining and raking. Using a combination of methods is the most effective method of managing aquatic weeds.
Herbicide Safety, Technology and Application Techniques
Aquatic Weed Management: Herbicide Safety, Technology and Application Techniques
Aquatic herbicides are chemicals used to kill aquatic plants or severely interrupt their growth. About 200 herbicides are registered by the EPA for use in the United States, but only six are labeled for use in aquaculture sites. It is important that aquaculturists use these registered herbicides in a safe and effective manner.

Alternate Uses for Ponds
This document discusses uses for ponds other than fishing. These include livestock watering, fire control, wildlife habitat and swimming. Includes figures.
Crawfish Culture: A Louisiana Aquaculture Success Story
Crawfish Culture: A Louisiana Aquaculture Success Story
The crawfish aquaculture industry, located primarily in Louisiana, has remained viable and resilient despite some considerable constraints. Success can be attributed to several factors.
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.
