INTEGRATED LIVESTOCK-FISH FARMING:-2

Integrated layer chicken-cum-fish farming
The integrated layer chicken-fish farming operation is undertaken with the commercial strain of layers where the birds are kept at the floor over the pond. Though this integrated system of farming requires skilled management for both layer chicken and fish but it proves economically and technically viable at farmers condition. The economic analysis of this system revealed a net profit of Tk. 219.836.00/ha/year where the fish production cage rearing was 4.89 tons/ha/year (Nuruzzaman, 1991). Recently cage rearing of layers over the fish pond has been introduced. In this case droppings drop directly to the pond without any wastage.
Integrated broiler-fish farming
Integrated broiler-fish farming is a successful system practiced in the country in a small number. The economics analysis of this integrated system showed that this is economically and technically highly viable. But this system has got some limitation in rural areas of

WASTE UTILIZATION
The high cost of feed is the major constraint to intensive fish production. The raising cost of fish feed has brought interest in the utilization of animal waste in pond culture. The cowdung and poultry dried droppings as a direct fish feed showed that manure are poor substitutes for the components normally included in fish feed pellets. The maximum 30 percents dried manure may be included in the fish be feed to obtain equal growth with conventional fish feed pellets (Schroeder, 1980). The quality value of manure as a substrate for microbial growth is directly related to the feed the animal received. The concentrated feed gives the high value than the fibrous feed. Generally, the value of the manure, in increasing order is: cattle, sheep and goat, followed by pig, chicken and ducks.
POTENTIAL FOR FURTHER DEVELOPMENT
The importance of integrated livestock/poultryfish production system has began to be more appreciated. The package technology of this integrated production system has may minimize the animal protein gap at low cost. This increase fish production potential means of waste utilization which increase fish production potential without the use of supplemented feed normally used for fish production. Here is much potentiality for the introduction of the cultural system of fish where only the captural system is practiced. The exploitation of the potential of large number of fish pond through animal rearing make an important contribution to increase farm income and nutrition gap of small-scale farmers.
The Fisheries Research Institute has developed a simple and an economically viable production system of integrating fish culture and chicken/duck rearing. The pilot experiments of on-farm study for this technology has been completed with very promising results. This packaged technology has been taken to rural farmers in a large-scale as multi-location trials.
Bangladesh Livestock Research Institute has started an experiment to select the type/breed of duck with different level of duck nutrition for making this duck/fish technology more economic and productive to fit in integrated duck-fish production system in the country. This integrated system has a great production potential to decrease the malnutrition of the country by increasing animal protein production.
CONCLUSION
Two or three fold integrated production system like animal-fish-vegetable, or rice-fish are unique technology of diversifying food production and increasing the income of small scale farmers. There is a need for critical studies on animal/fish/vegetable integrated production system. Effort is required to standardize the fish size, stocking rate, feeding, species combination and feeding, type of animal, number of animal and their size; age and diet, quality of seasonal factors will also have to be considered. As the success of integrated system depends on low production cost and high returns, the management techniques for animals will have to be improved. Feeding technology for reducing feed cost, faster growth and higher yield of animals should be adopted. The standard methodology for this region matched with available resources need to be developed. Extensive efforts for transferring this production technology to the farmers through direct linkage need to be organized through structural support and marketing system for upliftment of rural poor. Liquid manure of effluent from bio-gas digester can be matched with this production technology, if possible human excreta can be added in this technique.
