Answers
Answer:
Fish are aquatic, cold blooded and craniate vertebrates belonging to the super class Pisces under phylum Chordata.
Culture fisheries is the cultivation of selected fishes in confined areas with utmost care to get maximum yield. The seed is stocked, nursed and reared in confined waters, then the crop is harvested. Culture takes place in ponds, which are fertilized and supplementary feeds are provided to fish to get maximum
There are two main types of fisheries: Inland fisheries and marine fisheries.
- Inland or Fresh Water Fisheries:
Inland fishery deals with the fishery aspects of waters other than marine water. Potentially, the vast and varied inland fishery resources of India are one of the richest in the world. They pertain to two types of waters, namely, the fresh and the brackish. The former includes the country’s great river systems, an extensive network of irrigation canals, reservoirs, lakes, tanks, ponds, etc.
- Marine fishery
Marine fishery deals with the fishery aspects of the sea water or ocean.Marine fisheries provide food directly from ecosystems and are sensitive to climate change. Most human food production comes from heavily modified agricultural ecosystems. But fisheries are not generally manipulated and supplemented (e.g., with fertilizer) but rather produce food from ecosystems that are minimally managed. The direct link from ecosystem to human food is especially strong in marine fisheries and the impact of climate on that production is clear.
