    BIODIVERSITY CONSERVATION TECHNOLOGIES IN FISHERIES

    Description
    Overfishing and irresponsible fishing practices have long been recognized as leading causes that have reduced aquatic biodiversity, along with other causes such as pollution, habitat destruction and fragmentation, non-native species invasions and climate change. The FAO Code of Conduct for Responsible Fisheries and the international instruments pertaining to fisheries and biodiversity conservation stress the need for developing selective and eco-friendly fishing gears in order to conserve resources, protect non-targeted resources and endangered species like sea turtles and minimise environmental impacts of fishing. Various types of bycatch reduction technologies have been developed in the fishing industry around the world, in order to minimise the impact of fishing on non-target resources. These devices have been developed taking into consideration variation in the size, and differential behaviour pattern of shrimp and other animals inside the net. Semi-pelagic trawl system has been developed as an alternative to shrimp trawling in the small-scale mechanized trawlers operating in the tropical waters. Sources of pollution from fishing operations which affect fisheries environment include emissions of greenhouse gases (GHGs) and plastic debris originating from abandoned, lost and abandoned fishing gears. Enforcement of bycatch reduction technologies, promotion of low impact and fuel efficient fishing systems and smart trawling techniques, along with regulation on total fishing effort at sustainable levels and maintenance of Marine Protected Areas will facilitate protection and restoration of biodiversity and enhance the resilience of the fish stocks to fishing pressure. In this paper, various approaches to minimise the impact of fishing operations on biodiversity in fisheries environment are discussed.
