Improvement in food resources
1) Poultry need to be protected from various diseases caused by bacteria, fungi, viruses, parasites and nutritional deficiencies, through proper treatment, sanitation and vaccination.
2) In fish production, both the finned true fish as well as shellfish are obtained from marine or fresh water through capture fishing or culture fishery.
3) India’s marine fishery resources are the vast coastlines and extensive seas; the freshwater resources are canals, ponds, reservoirs and rivers whereas the brackish water fishery resources are estuaries and lagoons.
4) In India, marine fishes such as pomphret, tuna, mackerel and sardines are located through satellites and echo sounders and captured using fishing nets.
5) Marine fish farming of high economic value fishes like mullets, oysters and prawns are done in sea water.
6) Fresh water fish production is mainly carried out through aquaculture.
7) Composite fish culture system is used commonly for fresh water fish farming. In this system, five or six fish species with different food habits are farmed together in a single pond, so as to increase the yield of fish.
8) Since high quality fish seed is not always available, fish are nowadays bred using hormonal stimulation, thus ensuring continuous supply of the seed.
9) Bee-keeping is a low investment activity carried out by farmers to obtain honey and wax.
10) Apis cerana indica, Apis dorsata and Apis florae are the Indian bee varieties whereas Apis mellifera is an Italian variety used for commercially producing honey.
11) The availability of sufficient amount of pasturage as well as the type of flowers decides the quality of honey.
