Hiiiiii.....

Here Is Your Answer...

In composite fish culture more than one type of compatible fishes are cultured simultaneously in same pond. Example Catalas are surface feeders, Rohus are middle zone feeders, Mrigals and Common Carps are bottom feeders and Grass Carp feed on weeds, together these species can use all the food in the pond without competing with each other.In this system both local and imported fish species, a combination of five or six fish species is used in a single fish pond. These species are selected so that they do not compete for food among them having different types of food habitats.As a result the food available in all the parts of the pond is used. Fish used in this system include catla and silver carp which are surface feeders, rohu a column feeder and mrigal and common carp which are bottom feeders. Other fish will also feed on the excreta of the common carp and this helps contribute to the efficiency of the system which in optimal conditions will produce 3000-6000 kg of fish per hectare per year.

(a): one problem is that is one fish have some disease than it will spread in all the area this leads to disease in other fishes also..

we can control it by proper caring of fishes and by giving some useful medicines to them..

(b): Bee keeping is done to get wax and honey. Bee-keeping should be done in a good pasturage as the quality and quantity of honey depends on the flora of the pasturage available for nectar and pollen collection.

(c): Name of one local bee is "APIS INDICA" .it is also known as indian bee

(d): Quality of honey depends upon good pasturage..
