- Pisciculture (fishery) is the rearing and production of fish for food, while aquaculture includes other aquatic animals also.
- Fish are a rich source of protein and vitamins, and fish oils are widely used for nutritional and industrial purposes.
- Fish culture is of two types—freshwater fisheries (ponds, rivers, lakes) and marine fisheries (sea), with preservation by freezing, drying or canning.
Definitions [9]
Define Vermicompost
Vermicompost
Vermicompost is a kind of manure, rich in organic matter and nutrients, which is derived from organic wastes of plant and animal origin by the activity of earthworms. The latter promotes soil aeration, crush and mix soil particles and convert the nutrients into simpler forms.
The earthworms are popularly known as farmer’s friend or Nature’s ploughman. The most common species of earthworm used for decomposition are Dichogaster bolani.
Define Green manure
Green manure
Green manure is a kind of manure that is prepared in the field itself to enrich the soil in nitrogen and phosphorous. Green leguminous and non-leguminous plants are mulched by ploughing and then left in the field to decompose by the activity of natural decomposers such as bacteria and fungi. The most commonly used green manure in India is sun hemp, sweet clover, cow-pea, berseem, cluster bean etc.
Define Biofertilizer.
‘Biofertilizer’ contains living micro-organisms which, when applied to seed, plant surfaces, or soil, colonizes the rhizosphere or the interior of the plant and promotes growth by increasing the supply or availability of primary nutrients to the host plant. Thus, biofertilizers are organisms that enrich the nutrient quality of the soil.
Define Principal nutrients.
Nitrogen (N), Phosphorous (P), and Potassium (K) are the three important nutrients among the various nutrients needed for plant growth. These three are called Principal Nutrients.
Definition: Pisciculture
Pisciculture (fishery) is the practice of breeding, rearing and harvesting fish in natural or artificial water bodies for food and other economic uses.

Pisciculture
Pisciculture or Fish culture is the process of breeding and rearing fishes in ponds, reservoirs (dams), lakes, rivers, and paddy fields.
Definition: Apiculture
