frameworks towards adoption of the stipulations in the Code of Conduct for
Responsible Fisheries (CCRF) and its effective implementation will help to conforming to the issues that needs to be addressed by fisheries in general and climate
related changes in particular.
Steps to reduce the quantity of GHG emissions
(a) Development of fishing vessels with energy saving features
Fuel use for navigation to and from the fishing grounds and also for scouting
operations by fishing vessels is the single most important component that contributes most to the GHG emissions by fishing vessels. The quantity used varies with
different fishing methods. Often the vessels using active gear like trawlers consume
more fuel. Right sizing of the engine and the length of the vessel (Baiju and
Boopendranath 2014) and use of bulbous bow and kurt nozzles are found to reduce
the fuel consumption in fishing vessels. An energy efficient, multi-purpose green
fishing vessel developed by ICAR-CIFT, christened FV Sagar Harita, for deep sea
fishing operations is shown is Fig. 4. The power for the navigational lights and other
related requirements are met by solar panels installed in FV Sagar Harita. This vessel has been recently adopted as a standard for deep sea fishing vessels in India.
(b) Energy efficient fishing gears
Resistance by the gear material forms about 60% of the total drag offered by
active fishing gears like trawls. Reduction in the total quantity, use of thinner twines
and use of larger meshes can significantly reduce the drag and hence the fuel
