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 September/October 2012
Crawfish News September/October 2012 (Vol 5, No 5)
This newsletter discusses the management of water for fall flood-up, managing excess water from Hurricane Isaac, and understanding oxygen consumption in crawfish ponds.
Production of Food Fish
Red Drum: Production of Food Fish
There are two methods used in the production of food-sized red drum. The more conventional method is semi-intensive culture in ponds. The other method, intensive indoor raceway culture, is unproven from an economic standpoint. This publication focuses on pond production.
Crawfish Production: Pond Construction and Water Requirements
Crawfish Production: Pond Construction and Water Requirements
This Southern Regional Aquaculture Center fact sheet discusses pond design, layout and construction for crawfish monocropping and rotational production systems as well as water requirements for farming crawfish, including important water quality parameters, their desired levels and water consumption budgets.

Crawfish News September 2010 (Vol 3, No 6)
This newsletter discusses managing water for fall flood-up, the importance of BOD on water quality and oxygen management in crawfish ponds, and crawfish industry news.
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).

Cocahoe Minnow Production Manual
Cocahoe Minnow Production Manual
A comprehensive guide to culturing cocahoe minnows. This manual covers topics including spawning, feeding, disease, water quality, best handling practices, production economics, vendor contact information and more.
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.
