Odisha explores biofloc fish farming

Bhubaneswar , Aug 24:

To provide employment to people during the pandemic period, the Odisha government has launched a new scheme for promoting intensive aquaculture through Biofloc technology in fisheries, a minister said.

Biofloc based farming system is a new technology for the promotion of intensive fish/ shrimp production in a limited area without significantly increasing the usage of the basic natural resources of water and land.

A person having small landholding (as small as 150-200 square metre of land) and having either municipal piped water supply or bore well water supply can establish this business with a small investment. In Biofloc technology, the waste organic matter in the tank, such as feed waste, is digested using probiotics (helpful bacteria) and carbon source such as molasses and gets converted to fish feed.

This programme aims to support fish farmers and young entrepreneurs for generation of income and livelihood support, said Fisheries and Animal Resources Minister Arun Kumar Sahoo .In normal pond based farming system, one acre of an earthen tank (4000 square metre area) produces about 2,000 kg of fish in 6 months; while in biofloc fish farming system, the same 2000 kg fish can be produced only from 4 small tanks of each 4-metre diameter and 1.2-metre depth installed in a floor area of about 100-150 square metre, the minister said.
