Abstract

Vembanad lake is the second largest brackish water lake in India and is known for its rich biodiversity. The study investigates the fish diversity, stake net fishing and seasonal variation in species distribution along the Puthenvelikkara backwaters of Vembanad Lake. A total of 30 sampling events using different gears were made during the period from January 2020 to February 2021. Total 2301 individuals were encountered, comprising 54 finfish species and 7 shellfish species from 34 families, 13 orders and 50 genera. Fish abundance peaked during pre-monsoon season, and the lowest were recorded in post monsoon season. Mugil cephalus, Penaeus indicus, Etroplus maculatus, Etroplus suratensis, Stolephorus indicus, and Ambassis ambassis were found to be the dominant species in the catch. Stake nets are predominantly utilized to target prawns, which waft with the tides. The Gross Energy Requirement (GER) was calculated to be 5.19 GJ.t fish-1, which is surprisingly excessive for a stationary passively operated gear. The obtained energy efficiency ratio was 0.65, while the energy intensity value was 1.54. The high value of GER of this passively operated, non-motorized gear system is due to the low magnitude of landing by the gears.
