List one problem associated with composite fish culture

Posted by Anuj Sood 7 years, 4 months ago

1 answers

Yogita Ingle 7 years, 4 months ago

one problem with composite fish culture is that many of these fishes breed only during monsoon . The fish seed collected can be mixed with that of other species . Thus ,a major problem in fish farming is the lack of availability of good quality seeds . This problem can be overcome by breeding fish in ponds using hormonal stimulation. This ensures the supply of pure fish seed in desired quantities.
