The New Caledonia blue shrimp Litopenaeus stylirostris is commercially produced under semiintensive rearing conditions. The size of the farming earthen ponds (5–10 ha) and the subsequent production constraints make it difficult to use them as experimental units for random experiments. Moreover, since every pond has its own characteristics, ponds' effects cannot be ruled out, thus making it hard...

The present study provides a characterization of water quality and plankton samples in earthen fish pond in Rajshahi, Bangladesh. Sampling was done over a period of six months, running from October, 2004 through March, 2005. All the water quality parameters were within the optimal ranges for plankton productivity. Temperatures varied from 19.75 to 27.25 degrees C; transparency, 24.75-29.50 cm; ...

The feasibility of totally replacing the fishmeal component of marine shrimp (Litopenaeus vannamei) diets was examined both in the laboratory setting and during a full–scale commercial trial. Animals were fed either a traditional fishmeal–based diet or one in which complete replacement of fishmeal, on a per protein basis, was manufactured using a yeast–based product, NuPro®. Laboratory studies ...

In the United States, bighead are polycultured with channel catfish in approximately 5,100 acres of earthen ponds, including an estimated 4,000 acres in Arkansas, 500 in Mississippi, and 600 in Alabama. Bighead are an important source of additional income that, at times of low catfish prices, has kept some fish farmers in business. The primary market is to live-haulers who sell to specialty mar...

An experiment was conducted in nine 200-m2 earthen ponds at the Asian Institute of Technology (AIT), Thailand from 17 July 2003 to 3 March 2004 (230 days). The objectives of the study were to assess the feasibility of co-culture of lotus and hybrid catfish in intensively fed ponds, to assess nutrient recovery from feed waste by lotus plants, to assess pond mud characteristics after lotus-fish c...

The study was conducted to evaluate the effect of artificial feed and adding organic manures to the earthen ponds on the growth and body composition of genetically improved farmed tilapia (GIFT). A total of 160 fish were stocked in each of the two ponds for 90 days. Fish in both ponds were fed with supplementary feed containing 30% crude protein at 4% body weight. Pond 1 was fertilized using co...

Animal protein, generally fish meal, has traditionally been used in the diet of channel catfish. However, our previous research indicates that animal protein is not needed for growing stockersize catfish to food fish when the fish are stocked at densities typical of those used in commercial catfish culture. Whether this holds when fish are stocked at high densities is not known; thus, we conduc...
