Feeding- The nutrients needed for the growth, development and general maintenance of the
body.
Rearing- Looking after the health of the animals as well as production of clean milk.
Breading- Cross breeding of indigenous variety with exotic breed in order to produce good
quality, high yielding breeds.
17. Fertilizers provide various essential nutrients like nitrogen, phosphorus and potassium to
increase the crop productivity. But continuous use of fertilizers destroys soil fertility by
changing the soil chemistry, killing the microbes in the soil and dehydration and aeration of
the soil. So, a fertilizer in long term harms the soil.
18. Fishing can be done by two ways namely capture and culture in marine as well as fresh
water ecosystem.
Capture fishery_ The fish is caught from natural waters both marine and inland. Modern
technology is adopted in capturing the fish and its storage before marketing. It includes echo
sounders and satellite receptors.
Culture fishery_ It is cultivating, rearing and harvesting of fish. Culture fishery is also called
fish farming. Culture of marine fin fishes, shell fishes and sea weeds is called mariculture.
