Abstract

In Andhra Pradesh, India, the culture of marine finfishes such as Indian pompano and Asian seabass has been demonstrated in cages in Krishna and Godavari backwaters by the Regional Centre, ICAR-Central Marine Fisheries Research Institute (ICAR-CMFRI), Visakhapatnam, involving fishermen and marginal landless aqua farmers. Open sea cage culture of orange-spotted grouper and Indian pompano has also been demonstrated in Visakhapatnam, Srikakulam and East Godavari districts of Andhra Pradesh. From the 14 success stories documented, enhancement in net income in the range 50.32%–257.14% was evident by transforming people from different avocations such as agriculturists, wage earners in agriculture and allied sectors, business professionals, fish traders, traditional fish farmers and artisanal fishers to marine finfish farming. The benefit ratio of cage farming among the adopted farmers was found to be 1.33 and 1.31 for estuarine and marine cages respectively. The impact was realized on livelihood enhancement due to the technological interventions of cage culture under the technological, social and economic dimensions

Abstract

Globally, trawl is the major fishing gear used in marine fisheries and in India, it contributes to more than one-third of the marine fish production. Trawl fishing has been critically evaluated from a sustainability perspective, especially analysing its bycatch composition. Most of the bycatch from trawlers contains valuable edible species with high market demand. However, a portion of the bycatch which does not have such demand in the edible fish market, known as low-value bycatch (LVB), continues to be a matter of concern from an ecological and economic perspective. During 2017–19, 30–60% of trawl landing in India was constituted by LVB, which was mainly used for fishmeal preparation. To enhance the value and utility of LVB, this study explores the possibility of converting waste from LVB into edible resources using pufferfish and triggerfish. It also highlights the positive impact of efforts by different Government agencies for bycatch mitigation like the implementation of minimum legal size in reducing the juvenile component in bycatch, with a social survey-based account of fisher’s perceptions and suggestions on successful bycatch mitigation

Keywords

Ecological impacts, fishery economics, low-value bycach, minimum legal size, trawl.
