Enzymes are basically a type of protein in biological systems. They are generally used as catalysts in order to catalyse the rate of reaction. Feeding these enzymes in the aquaculture sector has some nutritional advances. Application of enzymes reducing the effects of antinutritional factors, improves the dietary energy resulting in better performance of fish/shrimps. Feed enzymes in the form of granules help enzymes to stay for longer time durations and are suitable for pelletisation process. Efficiency of feeds needs to be at maximum for economical operations.

In the present study was investigated that, the influence of different feed additives viz., fish meal, shrimp head meal and soy flour on the breeding performance of goldfish. These three major ingredients were mixed in the feed at three different concentrations at 20, 30 and 40%. Totally, 15 numbers of goldfishes were stocked in 50 L capacity FRP tank for breeding. Every day the fishes were fed with 5% of the body weight.

A 60 days feeding trial was performed to assess the potential use of shrimp head meal (SHM) as complete replacement of fish meal (FM) in commercial diets of Nile tilapia (Oreochromis niloticus) fry.Quadruple groups were fed each of five isonitrogenous (40%) diets were formulated to contain graded levels of SHM at 0% (control diet, T1), 25% (T2), 50% (T3), 75% (T4) and 100% (T5), respectively.

Infectious diseases are quiet common in shrimp culture operations. Apart from infectious diseases certain syndromes affecting the culture operations in the shrimp farms particularly from Andhra Pradesh and Tamil Nadu. Running mortality syndrome is such type syndrome associated with morbidity and mortality which leads to less productivity. In the present study we have examined the haemolymph and hepatopacreas of the infected shrimps. The results revealed that, the affected shrimp showed the higher percentage of Vibrio species such as Vibrio parahaemolyticus and Vibrio azureus.

The present study was carried out to understand the dietary ginger, garlic and fenugreek on growth performance on Litopenaeus vannamei L. Vannamei was fed with three different herbal powder of ginger, garlic and fenugreek of varying levels of 1%, 2.5%, 5%, 2%, 4%, 6%, 0.5%, 1% and 1.5% of concentrations respectively to assess the optimal growth promoting potential. The feeding trial was continued for 63 days with triplicates in each treatment. The growth parameters (ABW, weight gain, SGR), feed efficiency parameters (FCR) and survival rate were significantly (P ginger > fenugreek > control.

The increase in the human population in addition to the massive demand for protein of animal origin forced the authorities to seek for additional sources of feed supplies. Aquaculture is the world worth coming expansion to compensate the shortage in animal protein. Feed in aquaculture plays an important role in the production cycle and exert threshold on both practical and economic aspects. Feed additive sectors are expanding day after day to achieve better growth and health for fish and shrimp and to meet the potential requirements of the culturists.

This field study was performed to demonstrate that Bacillus aquimaris SH6 spores administered as a feed supplement in adequate amounts confer beneficial effects to the whiteleg shrimp. Shrimps were administered either B. aquimaris SH6 spores at 1×106 CFU g-1 pellet (SH6 group) or a mixture of SH6 and B. subtilis SH23 spores at 5×105 CFU g-1 pellet for each strain (SH6-SH23 group). After a 28-day feeding period, the number of SH6 spores in the gut of whiteleg shrimp in the SH6 group and the SH6-SH23 group were 5.7×103 CFU gut-1 and 7.7×103 CFU gut-1, respectively.

Chitosan with small content in the feed (0.48 - 0.75%) could be selected to prepare shrimp feed-pellet having so high water-stability that met the Standard of Vietnam Ministry of Fisheries 28-TCN 102/1997. The radiation treatment at sterilization doses (20 - 30 kGy) was evaluated as the most practical technology because irradiated chitosan with reduced content of 0.34% has capacity to be prepared feed-pellets as stable as comparable to imported products.

This Minor Field Study (MFS) was performed by Teresia Lindberg and Anna Nylander, who are both studying Eco-toxicology at Uppsala University in Sweden. The report is a Master´s thesis for Teresia Lindberg. The Swedish International Development Agency (Sida) finances a number of so-called Minor Field Studies for students or young people to carry out a research project in a developing country. The study usually takes place in one of Sida´s target countries and is part of a local Sida-sponsored aid programme.

The purpose of the study was to analyze the current practice of shrimp farming in the north central Vietnam, to evaluate the status of agricultural production and economic conditions - social and environment, and determine the limit application of better management practices. The report presents the results of a survey of 90 shrimp farmers in north-central provinces of Vietnam (Ha Tinh, Nghe An and Thua Thien-Hue). Shrimp production costs mainly by feeding (average 65% of total cost) for different varieties of food between provinces.

Tiger shrimp (P. monodon) and marine fishes are common fish cultured in coastal area of Vietnam. The study on nutrition for such species has not much when compared to freshwater fish species. Trash fish is the traditional feed for marine cultured fish and tiger shrimp in semi-intensive system. The supply is not stable in term of quality and quantity. Moreover, the price has increased. Therefore, finding alternative feed for trash fish is very important and crucial issues Using pellet feed in which fishmeal was replaced by plant protein that started in 90’s decade.

Shrimp farming is an evolving sector of agriculture that creates important economic opportunities in many rural communities plagued by under and unemployment. This water farming practice relies on the wise and responsible use of coastal natural resources and habitats. The long-term, local success of shrimp farming is also influenced by global market forces, consumer preferences and international food safety standards. Advances depend on accessibility of critical research, educational and laboratory services.
