Am thinking on investigating adaptability of bagrus bayad for aquaculture
Hello Hassan,
Whenever anyone thinks of a wild fish species to cultivate because of its utility then the first step is to start with the transfer of the broods and then breeding propagation for about three years. Only then other things in the form of research can be done.
It imposes:
- control of the various stages of the development cycle from egg stage to commercial size,
- knowledge and control of food and feeding conditions of the various stages,
- control of environment conditions of the breeding: choice of basins, quality of breeding water, etc ..
In my view the following points have to be taken into consideration.
the availability of natural seed, growth rate under controlled condition, feeding nature, easy manipulation of reproduction and less complicated life stages.
Another interesting area of research is genetic improvement of cold-water fish species.
This article looks like a good place to start: http://www.fao.org/3/a-ak505e.pdf. You already have a family of fish with a history of being amenable to spawning and rearing in captivity. Of course each species is different. Once past captive spawning, the big questions are resistance to disease, cost of feed, food conversion ratios, growth rate, yield per fish, production cost, cost of bringing to market, market price etc. In my opinion you have several things on your side, but the research and capital necessary to bring this species up to a commercial scale operation could cost millions of dollars (US).
Natural habitat study. Possibilities of captive maturation and breeding.
Food and feeding habits of various life stages. Growth parameters. Consumer acceptability.
