Abstract

Internationally, marine spatial planning (MSP) is an integral part of the decision-making protocol for setting up activities in the marine zone, be it the establishment of industries, exploration and mining for oil and minerals, deciding of surface transport, ensuring national security, exploitation of living and non-living resources, or conservation and management of resources and ecosystems. Satellite-based technologies like remote sensing and geographic information system are two powerful tools that provide a common platform to present information on different activities from the marine zone. This would enable the planners and policymakers to interpret the interaction between various factors and derive judicious decisions on the allocation of space and resources to different segments or activities in marine zone. This article reviews how MSP is being used as a decisionsupport tool in various countries for the peaceful coexistence of different stakeholders in the marine zone. It also discusses initiatives in India along with a reminder on the responsibility of the country as a signatory of international organizations to give importance on developing MSP for the conservation of resources as well as marine ecosystems.

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
