CHENNAI: In a serious breakthrough, the Central Institute of Brackishwater Aquaculture (CIBA) has efficiently captive bred Grey Mullet (Madavai), a high-valued industrial brackishwater fish, for the primary time within the nation in sync with Government of India’s blue revolution mission. This had remained elusive for greater than three many years.
Due to their texture and style, grey mullets are the popular alternative of customers and fetches good market value within the vary of Rs 350 to Rs 500 per kg. “Fast growth rates and omnivorous feeding habit, acceptance of formulated pellet feed makes it an ideal fish candidate for brackishwater aqua farmers with potential output of 4 tonnes per hectare/crop,” CIBA director KK Vijayan informed The New Indian Express.
For the previous a number of many years, India has made a number of ‘failed’ makes an attempt to develop captive breeding technology for grey mullet. One of the first causes is grey mullets have a brief annual reproductive interval restricted to only a few weeks throughout monsoon and reproductive dysfunctions in captivity.
“One-time breeding character of the fish further contributed to failure in efforts to captive breed. But, grey mullets are high-value brackishwater finfish species exhibiting fast growth rates. The species is an ideal candidate for Polyculture and Integrated Multi-trophic Aquaculture systems. Also, grey mullet is the most widespread species of the family Mugilidae which comprises 20 genera and 70 species. Considering its significance in brackishwater aquaculture, CIBA has given greater impetus in the breeding of grey mullet since 2015, giving special focus on developing a captive broodstock and breeding. As a result of these efforts, successful breeding and larval production were achieved using pond reared broodstock in 2016-17. This season by December-January, CIBA has completed producing its third batch of hatchery-reared grey mullet fingerlings,” Vijayan mentioned.
Further, CIBA additionally formulated indigenous pellet feeds for the broodstock, larvae, nursery and grow-out feeds. So, a whole indigenous hatchery technology for grey mullets is prepared for large-scale aquafarming.
On Thursday afternoon, grey mullet seeds can be handed over to potential enterprising farmers, from Andhra Pradesh, Tamil Nadu and Kerala. The seeds can be raised of their respective farms and developed into F1 broodstock, which might be introduced again to CIBA hatchery for additional breeding and seed manufacturing.
“These initiatives towards species domestication may make a wider breeding window of grey mullet available and the process of induced maturation less challenging,” scientists mentioned.
Presently, CIBA has already standardised seed manufacturing of assorted brackishwater meals fish species like Asian seabass, milkfish, pearlspot, whiskered catfish and likewise decorative species equivalent to noticed scat, moon fish, orange chromide.
