Kochi: The Central Marine Fisheries Research Institute (CMFRI) has issued a strict advisory to fishermen along the Kerala coast to refrain from catching juvenile sardines smaller than the legal minimum landing size (MLS) of 10 cm. This directive comes as a large number of young sardines have been observed in coastal waters.
A recent study conducted by CMFRI revealed that favorable rainfall conditions led to increased productivity of the sea surface, contributing to the abundant availability of sardines on the Kerala coast. However, the study also identified that an increase in sardine population has gradually led to a decrease in food availability, subsequently impacting their growth.
Dr. Grinson George, Director of CMFRI, addressed concerns regarding misinterpretations of the institute’s study on sardine growth. He clarified that any interpretations suggesting that sardines would no longer grow are entirely inaccurate and misleading.
Dr. George emphasized that juvenile fishing should not be encouraged under any circumstances. He stated that coastal waters continue to be highly productive, supporting a large population of small sardines. To ensure the sustainable utilization of this resource, regulated fishing in accordance with the MLS is imperative. This approach is crucial for maintaining the sustainability of sardine stocks and safeguarding the livelihoods of fishermen.
CMFRI researchers further highlighted that the availability and growth of sardines are primarily influenced by environmental changes. They underscored the necessity of adopting sustainable fishing practices to prevent any decline in sardine populations, asserting that such measures are vital for the breeding and development of juvenile sardines. Principal Scientist Dr. U. Ganga reiterated that catching very small sardines could have a detrimental impact on overall sardine availability in the long term.
