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).

Lakes and ponds can develop dense stands of aquatic vegetation that interfere with intended uses and destroy the natural beauty of the water. Most aquatic weed problems result from poor planning and poor management. Manipulating factors such as water, light and nutrients can help prevent weed growth.

This report is a survey of Louisiana wild commercial crawfish license holders conducted in 2010 to determine their preferences and perspectivesof actual and hypothetical regulations and management practices of the wild commercial crawfish fishery in Louisiana.

The high fish densities demanded by the market effectively reduce the availability of natural foods for individual fish. Thus, intensively cultured fish are generally fed prepared feeds to support maximum growth.

The three main fish species raisedfor bait in the southern region are the golden shiner, the fathead minnow, and the goldfish. Together, these three species account for more than 90 percent of farm-raised bait and feeder fish sales in the United States.

Although other prawn species are indigenous to the southern United States, they do not reach the size of the Malaysian Prawn (Macrobrachium rosenbergii). This quality makes the Malaysian Prawn an attractive option for producers.

The final phase of freshwater prawn (shrimp) production is grow-out of juveniles to adults for market as a food product. This publication provides guidelines for stocking and managing a fresh water prawn production pond.

The largemouth bass (Micropterussalmoides) is one of several “basses” that are actually members of the sunfish family. There are two recognized subspecies, the Florida and the Northern, which will blend genetically.

A variety of factors can reduce populations in fish ponds during the spring.

Forage species are primarily stocked in private waters throughout the Southeast as a food source for largemouth bass and other predator species. Unfortunately, the ideal forage species for all management situations does not exist. Therefore, managers often attempt to maximize largemouth bass production by stocking a multi-forage base. In many southeastern states, private landowners must rely on private hatcheries as sources for appropriate forage species.

The crawfish aquaculture industry, located primarily in Louisiana, has remained viable and resilient despite some considerable constraints. Success can be attributed to several factors.

Throughout the world, pond production of freshwater shrimp is usually based on culture of Marobrachium rosenbergii, which is native to the Indo-Pacific region. The tropical nature of the species hinders production in cooler climates. In Louisiana, the major constraints to production include cost and availability of post-larvae for stocking and temperature intolerance.

Although many types of fish could be stocked into recreational ponds, few have the characteristics needed to provide quality fishing year after year.

Springtime diseases and oxygen losses in fish ponds are common throughout the Southeast.

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 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.

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.

This newsletter covers oxygen demand in crawfish ponds, dip-net sampling of crawfish populations, an introduction to crawfish population dynamics, and trap density and spacing recommendations.

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.

This article describes materials and techniques for the construction of pillow traps and pyramid traps used to harvest crawfish in Louisiana's commercial crawfish industry

Whether from aquaculture or the natural fishery, the supply of live crawfish is highly seasonal, with peak harvest occurring from March through June. Supply-and-demand relationships are reflected in price variations from year to year and from week to week during the crawfish harvest season. Because of restricted geographical areas of production, seasonal supply, unstable prices and limited consumer awareness, crawfish sales nationally have been limited but have increased in recent years.

Fingerling culture ponds are usually smaller than ponds used for grow out. The advantages to this practice, as well as food, water quality and harvesting requirements, are outlined in this publication.

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.

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.
