and practice for climate change adaptation and mitigation, livelihood sustainability enhancement through provision of know- how and do –on alternative income generating activities are some of the other interventions carried out by CMFRI. Mobile app for online fish sale As an adaptation strategy to improve income of fishermen and to help them cope up with adverse climatic events, the ICAR-Central Marine Fisheries Research Institute(CMFRI) developed a multivendor E-commerce website and associated android app (marinefishsales) through the National Innovations on Climate Resilient Agriculture (NICRA) project. The website and mobile app is aimed at helping fish farmers and fishermen to sell their farmed fish and marine catch directly to the customers online and to fetch better income without depending middlemen. Various fishermen SHGs can register as vendors (fishers and farmers) based on their fish products and update their stock availability under pre-approved categories and products, which shall be displayed in the website and associated mobile app. Customers visiting the website or app could place the order and subsequently the registered fisher/farmer shall be notified through email and SMS, upon which the quality products within the pre-assigned time frame shall be delivered, enabling direct product sale between customers and SHGs. Fishery socioeconomics, marketing, trade and fisheries governance Studies on economics of fishery enterprises and socio-economic conditions of fisher folk come under the mandate of the ICAR-CMFRI. Valuation, estimation and analysis of marine fish landings and its economic performance, supply chain management, price behaviour of marine fish varieties, fish consumption patterns, impact of GST on fisheries sector and vulnerability of coastal villages are being estimated annually both at landing centre and retail market levels for different maritime states. An estimation of value of marine fish landings in India, during 2011–2017 indicated an increase of fish landings at landing centre level from ₹24,369 crores in 2011 to ₹52,431 crores in 2017, with an annual increase of 14.5%, while at retail centre level, increased from ₹38,147 crores to ₹78,404 crores with an annual increase of 15.08%. Economic performance of different fishing methods were assessed in different maritime states using the indicators like net operating income, capital productivity (operating ratio), labour productivity, input-output ratio and gross value added. Various communication tools are developed periodically for inculcating the concept of responsible fisheries management in the minds of the fishers.
