Major problem of fishery (or fish farming). It is procurement of pure seeds 9f high quality fish. This problem his been solved through hypophysation or hormonal treatment of selected fishes in breeding hapas.

The two ways of obtaining fish are (i) Capture fishery. Fish is caught from natural waters both marine as well as inland (freshwater bodies). (ii) Culture fishery. Fish is grown in water bodies through human efforts. The mature fish is harvested.

Larger sized birds require more feed. Summer adaptation is connected with egg laying. Little summer adaptation reduces egg laying. In order to get small-sized poultry birds having summer adaptability, it is desirable to (i) Either introduce the required exotic birds from outside and (ii) Cross breedRead more

In order to get small-sized poultry birds having summer adaptability, it is desirable to (i) Either introduce the required exotic birds from outside and (ii) Cross breed the local birds with exotic birds from outside. Small sized poultry birds are preferred for (a)’Lower requirement of feed (b) Higher egg laying capacity; (c) Lower requirement for space.
