News Excerpt
Recently, the Indian National Centre for Ocean Information Services (INCOIS), Ministry of Earth Sciences has reported the Oceans at Satellite data from ISRO that used to prepare the Potential Fishing Zone (PFZ) advisories.

●    About 7 million people living along the Indian coastline, spanning over 8100 km, are depending on fishing for their livelihood and India’s coastline has a rich diversity of marine life.
●    There are nearly 1570 species of finfishes and around 1000 species of shellfishes known from the seas.
●    Oceansat-2 is an Indian satellite mounted with a Colour Monitor instrument on Oceansat-1 able to monitor sea surface.
●    Indirect method of monitoring fishing zone through sea surface temperature and phytoplankton pigments (chlorophyll a) at sea surface from satellites is found very ideal as it provides high receptivity and large spatial coverage making available a real-time picture of any one of these parameters or a combination of more than one parameter.

Potential Fishing Zone
    Potential Fishing Zone (PFZ) is a reliable and short-term forecast on the fish aggregation zones in the open sea.
    The Potential Fishing Zone (PFZ) is a proxy to potential shoals of fish aggregation will benefit the fishing community to reduce the time and effort spent in searching the shoals of fish, thus improving the profitability and hence, the socio-economic status.

Advantages of PFZ
1.    PFZ helps to locate the fish in the areas where fish congregate.
2.    Saving on valuable fuel and human drudgery.
3.    Reduction in search time by 30 to 70 %.
4.    Fishing period reduced from 3-5 days to 1-2 days.
5.    The PFZ forecast is more useful to pelagic gears like Purse seine, gill nets and long line, because the PFZ is derived from surface parameters like chlorophyll and sea

surface temperature.
6.    It may also be useful to mid water trawls and near shore and shore operated gears irrespective of depth.
7.    Traditional fishermen can benefit by the use of PFZ forecast when available near shore.

Fishing & Aquaculture in India
    The fisheries and aquaculture production contributes nearly 1% to India’s Gross Domestic Product (GDP) and more than 5% to the net agricultural GDP.
    The total fish production during 2017-18 is estimated to be more than 12 million metric tonnes, of which nearly 65% comes from the inland sector and about 50% of the total production is achieved through culture fisheries that constitutes about 6.3% of the global fish production.
    Fisheries in India is a very important economic activity and a flourishing sector with varied resources and potentials. India ranks second in the world in inland fish

production, next to China.
    Fish contributes substantially to the domestic food security of India which has a per capita consumption of more than 6.00 kg per annum

Challenges faced by fishery sector in India
    As per estimates, the majority of fish is wasted by being discarded at sea after the catch.
    In addition to the economic loss the issue of conservation is attracting increased attention.
    Fisheries suffer from insufficient institutional support, also lack of legal and political support especially for Fisheries.
    Aquatic pollution, destruction of fish habitats, loss in aquatic biodiversity due to a variety of anthropogenic activities. For Instance- Climate change, Global Warming.
    Unorganized market system, Non availability of skilled manpower, and Lack of value addition technology poses greater challenges in terms of resources.
    Decline in fish catch and depletion of natural resources due to over exploitation of coastal fisheries.
    Frequent confrontation of Indian Fishermen with Sri Lankan Navy

Way Forward
§    Integration of the blue revolution with MGNERGA would address the twin issue of employment and food. For Instance- Pond made under MGNERGA can be used for aquaculture promotion.
§    The government in association with regional academic institutions must impart skill and training to the fishermen in order to achieve sustainable fish practices.
§    Infrastructure bottlenecks need to be addressed for optimum economic returns. Affordable Cold Storage facilities, landing centers can help fishermen to fetch a good price.
