Learn About Pisciculture

Pisciculture or fish culture, included under the broad term 'Aquaculture', can be defined as the 'farming and husbandry of economically important fish, under controlled conditions. Pisciculture plays an important role in the economy of West Bengal. It helps in augmenting food supply, generating employment, raising nutritional level and earning revenue.

Characters of cultivable fish

The following criteria should be considered before selecting a fish for farming purpose.

  • Rate of growth: Fish which grow to a larger size in shorter period are suitable for culture. Examples Carps.
  • Adaptation to climate: The cultured species of fish should be able to adapt to the local climatic conditions of the farm.
  • Tolerance: The fish should have the capacity to tolerate wide fluctuations in the physico- chemical conditions such as oxygen, salinity, temperature of the water.
  • Acceptance of artificial feed: When more number of fish is to be accommodated in a limited space, there is the need for supplementary feeding on compounded diets. The fish should show ready preference for these feeds.
  • Resistance: It is desirable that the cultured fish is hardly enough to resist the common diseases and attack of parasites.
  • Amiability and compatibility: The fishes proposed to be cultured together ('poly culture') should be able to live together without interfering or attacking the other.
  • Conversion efficiency: The species of fish which give more edible flesh per unit of food consumed is preferred.
  • Consumer's preference: Food preference of people varies with the geographic regions. Hence, the species cultured should be easily marketable locally or to the targeted consumers.

Absolutely Necessary:

Fish farming may range from 'backyard' subsistence ponds to large scale industrial enterprises. Farming systems can be expressed in terms of input levels.

The following criteria should be considered before selecting a fish for farming purpose.

  • In extensive fish farming, economic and labour inputs are usually low. Natural food production plays a very important role, and the system's productivity is relatively low. Fertiliser may be used to increase fertility and thus fish production. We may use organic fertiliser also.
  • Semi-intensive fish farming requires a moderate level of inputs and fish production is increased by the use of fertiliser and/or supplementary feeding. This means the nutritional value of fish and the production of fish are increasing by proper
Advantage of Pisciculture:

The following criteria should be considered before selecting a fish for farming purpose.

  • 1) Supply necessary amount of protein in the form of fish meat.
  • 2) Protection of fishes from extinction.
  • 3) Maintenance of the balance of the ecosystem in the pond and lake.
  • 4) Upgrade the economic condition of the state as well as the country.
