ICAR-CMFRI develops hatchery technology for picnic seabream
In a breakthrough in diversification of the country’s mariculture activities, the ICAR- Central Marine Fisheries Research Institute (ICAR-CMFRI) has developed hatchery technology for picnic seabream (Acanthopagrus berda), a commercially important marine food fish. Also known as black seabream and goldsilk seabream, the fish is known for its excellent meat quality and high economic value. It has high demand in domestic market with a price of around Rs. 450 to 500 per kg. Locally called as karutha yeri, the fish is an excellent species for mariculture owing to its faster growth rate, strong resistance to diseases and ability to cope up with wide variations in environmental parameters such as salinity and temperature. The breeding technology was developed by the Karwar Research Station of ICAR-CMFRI.
Fishes collected from Karwar region were reared in the marine cage farm of the Station providing maturation diets, and regular ovarian biopsy was carried out to select matured fishes for breeding. The fishes spawned after 36 hours of inducement and the pelagic eggs hatched after 22 to 24 hours at a temperature of 28 to 30 0C. Fecundity was 0.25 million per female (450 g) and 86% of the eggs hatched after 24 hrs. Experimental larval rearing was carried out in 100 litre tanks with various live feed organisms such as Copepods, Rotifers and Artemia; stocking 100 eggs per litre. Metamorphosis of the larvae initiated in 24th day post hatch (DPH) with 9 % survival in a tank.
The achievement is expected to open up enormous scope for the country’s mariculture ventures in near future through species diversification. With the development of hatchery technology for picnic seabream, Indian mariculture is poised for a new surge with exponential increase in marine finfish production.
This is the seventh marine food fish of which breeding
technology has been developed by the ICAR-CMFRI. It
took around three years for the CMFRI scientists to develop the seed production
technology for this fish. Earlier, the institute had succeeded in brood stock
development of fishes like cobia, silver pompano, Indian pompano,
orange-spotted grouper, pink ear emperor and John’s snapper.
CMFRI adjudged as best research institute under ICAR
CMFRI wins ICAR’s highest award
The Central Marine Fisheries Research Institute (CMFRI) has been adjudged as the best research institute of the Indian Council of Agricultural Research (ICAR). The CMFRI won the Sardar Patel Outstanding ICAR institutions award, the highest award of the ICAR in the category of the large institutions with a cash prize of Rs 10 Lakhs, a Silver Plaque, Certificate and Citation.This is in recognition of CMFRI’s excellent performance in marine fisheries research during the period from 2014 to 2019.
This is the second time CMFRI bagging this prestigious award. Various cutting edge research activities including development of mariculture technologies such as open sea cage fish farming, seaweed farming, integrated multi-trophic aquaculture (IMTA) and breeding and seed production technologies for marine food fish and ornamental fishes which were aimed to enhance the income of fishermen helped CMFRI achieving the highest ranking among more than 110 agricultural and allied research institutes in the country. CMFRI’s efforts on preparing a range of policy guidelines, including the works on minimum legal size (MLS), National Policy on Mariculture and ecosystem-based management towards the sustainable utilization of marine fisheries resources were well appreciated. Its research initiatives in developing nutraceutical products from marine organisms to treat type 2 diabetes, arthritis, obesity, thyroid and hypertension also played a major role in winning the award. In addition, the institute exhibited leadership in winning several externally funded research projects such as National Brood bank for Cobia and Silver pompano and a Centre of Excellence and Innovation funded by the DBT. The institute also obtained many patents during the period.
