Pond systems. It is the most common method of fish culture. Water is maintained in an enclosed area by artificially constructed ponds where the aquatic animals such the finfish and shellfish are reared. The ponds may be filled with canal water, rain water, bore well water or from other water sources.
The commonly used chemicals, used as disinfectants, are formalin, malachite green, potassium permanganate and methylene blue and antibiotics are oxytetracycline, erythromycin, chloramphenicol and nitrofurans. Most of the farms use chloramphenicol, followed by oxytetracycline and erythromycin.
Fish nutritional needs vary by species. Herbivorous fish eat a feed mixture that may contain plant proteins (e.g., soy, corn), vegetable oils, minerals, and vitamins. In the wild, carnivorous fish such as salmon eat other fish.
In fisheries, the seed refers to the hatchling stage, the spawn stage, the fry stage and the fingerling stage, often known as the juvenile stage. These are the four stages of baby fish utilised as seeds in new ponds and fisheries.
They comprise centrifugal pumps, deep-turbine pump, submersible pump, propeller pump, and air-lift pump.
Fish are stocked in cages, artificially fed, and harvested when they reach market size. A few advantages of fish farming with cages are that many types of waters can be used (rivers, lakes, filled quarries, etc.), many types of fish can be raised, and fish farming can co-exist with sport fishing and other water uses.
Helping to identify appropriate policies and management strategies and ensuring that management and policy-making are learning processes is a key role for researchers. These processes should, at the same time as generating benefits, increase knowledge about the nature and dynamics of the fishery.
aquaculture, also called fish farming, fish culture, or mariculture, the propagation and husbandry of aquatic plants, animals, and other organisms for commercial, recreational, and scientific purposes
With the vast and varied Inland and marine Fisheries resources, fisheries and aquaculture in India plays an important role in feeding the rising global demand for protein rich food, foreign exchange earnings, reducing hunger and malnutrition apart from providing employment generation, livelihood to millions of fish farmers, fishers, fish traders, fish workers especially the marginalized and vulnerable communities of the country. During year 2021-22, India has not only become the 2nd largest fish producer accounting to 7.56% of total global production through sustainable utilization of resources but also stood as 4th largest exporter of fish and fisheries products taking Brand India from Local to Global. It contributes to about 1.24% to the country’s GVA and over 7.28% to the Agricultural GVA.
