crawfish manual
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.

Species Profiles for Stocking
When considering what fish to stock, determine your objectives in terms of food production, recreation, aesthetics or trophy angling and how much time you have to devote to pond management. Although many types of fish could be stocked into recreational ponds, few have the characteristics needed to provide quality fishing year after year.
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.
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.
Herbicides
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.

Stocking Procedures
This article discusses the procedures that should be taken to maximize the health of fingerlings when stocking your recreational pond.
Turbidity - Muddy Water
This document discusses causes of muddy pond water and ways to prevent and control it.
Publication cover
Fertilization
Description:Proper use of fertilizer can increase fish yields two to five times. Fish are easier to catch in fertilized ponds because plankton turbidity limits their vision, causing them to be less wary. Plankton blooms also reduce light penetration to pond bottoms, preventing growth of troublesome aquatic weeds.
Using Grass Carp in Aquaculture
Using Grass Carp in Aquaculture and Private Impoundments
Grass carp can effectively control aquatic vegetation, particularly submerged vegetation. The key to using grass carp is to stock the proper number based on their vegetation preferences, the water temperature, and the biomass and pond coverage of the plants.
Liming Ponds
This document provides information about when liming might be necessary and lime application methods.
