“…The neighbouring countries of the Maldives and the Chagos Archipelago both prohibit fishing of mobulid rays and could provide some protection if mobulid population distributions extend across the northern Indian Ocean. However, with far-ranging Sri Lankan fisheries that access the High Seas and at times even illegally fish within the sovereign waters of neighbouring nations or MPAs ( DFAR, 2013 ; BIOT, 2020 ; Kilgour, 2020 ), along with intensive and expanding fishing pressure from other Indian Ocean countries such as India ( Parappurathu et al, 2020 ), it is unlikely that regional spatial protections implemented by other countries will provide sufficient refuge from fishing pressure to prevent population declines. The mobulid conservation and management measure (Resolution 19/03) introduced by the IOTC in 2019 ( IOTC, 2019 ) provides a regional framework for reducing mobulid fisheries captures.…”

Background Expanding fisheries in developing nations like Sri Lanka have a significant impact on threatened marine species such as elasmobranchs. Manta and devil (mobulid) rays have some of the most conservative life history strategies of any elasmobranch, and even low to moderate levels of bycatch from gillnet fisheries may lead to significant population declines. A lack of information on life history, demographics, population trends, and fisheries impacts hinders effective management measures for these species. Method We report on mobulid fishery landings over nine years between 2011 and 2020 across 38 landing sites in Sri Lanka. We collected data on catch numbers, body sizes, sex, and maturity status for five mobulid species. We used a Bayesian state-space model to estimate monthly country-wide catch rates and total annual landings of mobulid rays. We used catch curve analyses to estimate total mortality for Mobula mobular, and evaluated trends in recorded body sizes across the study period for M. mobular, M. birostris, M. tarapacana and M. thurstoni. Results We find that catch rates have declined an order of magnitude for all species across the study period, and that total annual captures of mobulid rays by the Sri Lankan artisanal fishing fleet exceed the estimated annual captures of mobulids in all global, industrial purse seine fisheries combined. Catch curve analyses suggest that M. mobular is being fished at rates far above the species’ intrinsic population growth rate, and the average sizes of all mobulids in the fishery except for M. birostris are declining. Collectively, these findings suggest overfishing of mobulid ray populations in the northern Indian Ocean by Sri Lankan artisanal fisheries. We recommend strengthening the management of these species through improved implementation of CITES, CMS, and regional fisheries management actions. In addition, we report on the demographic characteristics of mobulids landed in Sri Lanka and provide the first record of M. eregoodoo in the country.

Indian fisheries sector is receiving increasing attention and policy support owing to the livelihood and foreign exchange potential of the sector apart from its nutritional significance. The Government of India has initiated â€˜Blue Revolutionâ€™ to augment the fish production and to strengthen the fish based value chain. But, unequipped manpower is often highlighted as one of the major deterrents for leveraging the full potential in harvest and post-harvest fisheries sector, which is highly skill intensive in nature. The issue would emerge more serious in case of marine fisheries. In this paper, we attempted to deliberate on the issue of skill-deficit that would emerge in harvest and post-harvest sectors of marine fisheries sector in India, and suggest measures to address them.
