Abstract

Analyses of trawl fisheries in Karnataka was done from 2008-2019 as part of a project on ‘Best practices in trawl fisheries’. The fishing days increased from 1 day trips to voyages of 14 days and depth of operation ranged from 11-200 m. Total area trawled ranged from 26324-45869 sq. km. Multiday trawl landings observed 269 taxa of which 224 species belonging to 111 families and 32 orders were identified. 68% were finfishes, followed by crustaceans (17%) and molluscs (14%) with major contribution from carangids (22 %), portunids (10%), \nclupeids (8 %), penaeids (7 %) and engraulids (6 %). Since 2017, percentage of pelagic fishes in trawl catch \nhas increased. Based on a survey, stakeholder attitudes were also assessed on various socio-economic aspects.
