Biofloc tilapia farming set to help India’s rural poor


CMFRI assisted members of five SC families in the region to launch a biofloc fish farming unit under the Scheduled Castes Sub-plan (SCSP). The group started by storing 1,800 genetically improved tilapia (GIFT) fry in a biofloc tank, set up next to their households.

CMFRI assistance includes setting up the 23,500-liter tank and providing fingerlings, feed and technical advice.

According to CMFRI, the self-help group will be able to earn an income of at least 135,000 rupees (approximately $ 1,800) over each 8-month cycle, and the fish will reach a minimum weight of 300g.

“Tilapia (GIFT) normally gains 300-500g of weight during this time as a result of this practice,” said Dr K Madhu, principal investigator of the project and principal scientist at CMFRI.

Biofloc enables high density fish farming in a controlled environment, in which fish waste is converted into useful nutrients.

The CMFRI will monitor the different phases of the practice continuously to allow maximum growth of the fish. A water quality kit was also provided to the group to maintain the required parameter, Dr Madhu said.

As part of CMFRI’s SCSP program, cage fish farming is undertaken by members of the SC community across the country, and biofloc farming aims to extend the benefits of this program to those without access to the plans. open water. The biofloc project is ongoing in the districts of Palakkad, Thrissur, Idukki, Kottayam and Kollam under the leadership of CMFRI. The tilapia fry were purchased from the MPEDA hatchery in Vellarpadam.
