CMFRI examine reveals constructive impression of monsoon trawl ban on Karikadi prawn assets

The monsoon trawl ban is just not detrimental to Kiddi (Karikadi) prawn assets, as an alternative it’s efficient in making certain the long-term viability of this specific commodity alongside Kerala coast, in accordance with a examine by the ICAR-Central Marine Fisheries Analysis Institute (CMFRI).

Kiddi prawn (Parapenaeopsis stylifera) is a considerable fishery alongside India’s southwest coast resulting from its excessive demand in home and worldwide markets. Fluctuations within the Karikadi catch following the implementation of mechanised fishing ban through the monsoon season had led fishermen to imagine that un-harvested prawns could be misplaced endlessly as these assets transfer away from the near-shore to deeper waters.

Nevertheless, CMFRI’s examine discovered that whilst these species do migrate to deeper areas, they continue to be accessible to present fishing strategies from areas at a depth of fifty to 100 metre instantly after the trawl ban interval.

Monsoon rainfall drives Karikadi prawns to deeper waters resulting from their desire for top salinity and low temperatures, the examine stated.

Furthermore, the Karikadi inhabitants in near-shore waters through the monsoon season is completely made up of juveniles, in accordance with this examine. Limiting fishing throughout this era facilitates continued recruitment of prawns, enabling the assets to develop in dimension and numbers. In consequence, the southwest monsoon trawl ban is advantageous to this species, the examine noticed.

Trawling exercise will be centered in direction of 50 to 100 metre depth between August – September (instantly following the ban interval) to gather the useful resource that migrates to deeper waters through the monsoon, the examine urged.

Additional, it additionally discovered that one a part of un-harvested large-sized Karikadi prawns are getting resettled alongside the Indian coast, as soon as the salinity is at their preferable vary within the coastal waters. The examine was printed within the newest subject of Regional Research in Marine Science.

This examine was carried out to deal with the socio financial points raised by the trawl fishermen of Kerala throughout a stakeholder assembly held at CMFRI, stated A P Dineshbabu, Head of the Shellfish Fisheries Division of CMFRI and the lead writer of the examine.

The examine supplied scientific proof for a way this species is distributed uniquely, utilizing GIS-based spatial distribution monitoring to discover how the motion and maturity of Kiddi prawns correlate with environmental elements, he added.
