The estimated marine fish landings from all the maritime states and two union territories in the mainland of India for the year 2021 was 3.05 million tonnes. This may reflect more diversity of species in a certain year,” said Dr Ghosh. Some fishermen tend to conduct their operations in Odisha and Tamil Nadu, but the landings will be done in Andhra Pradesh. “The increase in species does not necessarily mean that some new species have entered the waters of Andhra Pradesh form other coasts. For example, if the fishing is conducted in a particular area where the fish are more, the operations will end up with more diversity of species,” said Dr Ghosh. “These include the extent of fishing operations, area of operations, fishing operations season, the efficiency of the gear used for fishing, etc. Head of the Visakhapatnam regional centre, CMFRI, Dr Shubhadeep Ghosh, said that the recording of the number of species in a particular year will depend on several factors.

The Central Marine Fisheries Research Institute (CMFRI) recorded 255 species in Andhra Pradesh in 2021 compared to 216 species in 2018. These factors have led to scaled down operations, forcing some of the dependents to migrate to other means of livelihood.

Increasing fuel prices coupled with limited availability of fish stocks made fishing a capital-intensive sector and financially unviable for some. Overexploitation of marine resources over the years - that may have made it difficult for sustaining viable populations – is said to be the prime reason for this dwindling trend. It decreased to 2.07 lakh tonnes in 2021, reflecting a 40% drop from its peak in 2014. Since then, it has never crossed 3-lakh tonne mark.

VISAKHAPATNAM: The estimated marine fish landings from Andhra Pradesh’s coast in 2014 stood at 3.42 lakh tonnes – the highest for any year in the history of Andhra Pradesh.
