    Insights from elasmobranch catch composition and historical records


    We assessed elasmobranch diversity, abundance, catch rates and fishery characteristics using landing surveys in from central west coast of India, a major multigear, multi-species fishing centre, over three sampling periods. We sampled 3145 fishing trips and recorded 27 elasmobranch species, of which nearly half are categorised as “Threatened” by the IUCN. The catch was dominated by small-sized coastal species like the spadenose shark and the scaly whipray . Trawlers accounted for 64.9% of the catch, and captured smaller-sized individuals. Nonetheless, artisanal and gillnet fisheries had higher catch per unit effort for rays (5.1 ± 1.0) and sharks (10 ± 1.0), respectively, and captured significantly larger-size individuals. Through GLMs, we found seasonal, gear and fishery effects on the abundance and size of commonly caught species. Historically, 141 species have been recorded in this region, and a comparison with current catch suggests a shift in elasmobranch community structure.
