Marine Fisheries Policy Brief-1 Kerala

Kerala which has a coastline of 590 km ranks first in marine fish production of India, contributing nearly 25% (5.81 lakh tonnes on average) to the total annual production. The export of marine products from the State earns valuable foreign exchange besides affording innumerable job opportunities in the industry. The population depending on fisheries has steadily increased over the years and stood at 6,02,234 in 2005 (Anon., 2005). Kerala has been in the forefront of absorbing innovative and new technologies in fishing practices, which have led the marine fisheries sector to take a complex structure. The 1980s was an important period in the development of marine fisheries in Kerala. In the first half of the period the motorized sector grew rapidly and became the most important sector yielding the maximum catch in 1988. By that time, ringseine became very popular in exploiting the pelagic resources and replaced the boatseines to a very great extent. Huge size of the new net (450 to 1000 m long) and large number of crew (30 to 50) needed for its operation necessitated larger boats with high capacity outboard engines (3 outboard engines of 40 hp each). This facilitated extension of fishing grounds for the motorized sector. The fishing grounds covered by the mechanised sector also extended by increasing the boat size and fishing effort and efficiency through multi-day fishing during the late 90s

Marine pollution - its effects on living resources with special reference to aquaculture

Due to large scale industrialisation and indiscriminate discharge of effluents with high BOD, toxic chemicals and particulate matter reach the aquatic environment, either directly or indirectly. Enrichment of the coastal waters through nutrients and minerals lead to immediate and long term effects on the biota and fishery resources causing severe eutrophication or mass mortality. Among a large variety of pollutants which reach the aquatic environment, the domestic sewage, agricultural pesticides, industrial wastes, oil and oil dispersants, radioactive wastes and the polluted water from the coconut retting zones causes deleterious effects in the inshore and fish fanning areas

Environmental characteristics of the seasonal and perennial prawn culture fields in the estuarine system of Cochin

The paper embodies the results of investigations conducted to study the environmental characteristics of the prawn culture fields in the estuarine system of Cochin from Azhikode in the north to Kumarakam in the south including the Vembanad Lake

Brackishwater prawn farming in the Ashtamudi lake area(S.W.Coast of India)- Its prospects and problems

In the Ashtarnudi Lake area (Quilon Dist., Kerala) where scientific aquaculture practices of any kind were not in existence, CMFRI initiated a demonstration project for the culture of marine prawns in 1978. Fourteen ponds having a total extent of 2.06 ha, owned by M/s,Blackstone industries at Neendakara were selected for the above purpose

Trends in secondary production in the inshore waters of the seas around India

CMFRI has been monitoring the microscopic organisms which belong to the categories of phyto and zooplanktons, being a reliable tool for the identification of areas prone to industrial and natural pollution and for understanding its extent and intensity, especially in the inshore areas selected centres along the Indian coasts.These studies assist in foretelling any alarming situations developed in the living environment that may affect the commercially important resources adversely. The pattern of the occurrence and abundance of zooplankton along the Indian coasts from Bombay on the west coast upto Madras on the east coast were described.The samples were collected from Bombay, Karwar, Calicut, Vizhinjam, Tuticorin, Mandapam and Madras. In conclusion,the rate of secondary production on the west as well as on the east coasts during the 1981-82 period was comparatively lesser than during the previous year

Environmental features of the sea around Lakshadweep

The sea around Lakshadweep forms a part of the southeastern Arabian Sea, also known as the Lakshadweep Sea. The paper detailed about the environmental features of the sea such as wind system, sea surface circulation, hydrographic conditions etc. around Lakshadweep

Prawn fauna (Crustacea: Decapoda) of India - An annotated checklist of the Penaeoid, Sergestoid, Stenopodid and Caridean prawns

Twenty four species of Pandalid shrimps reported from the Indian waters, of which six genera (Chlorotocella, Chlorotocus, Chlorocurtis, Dorodotes, Heterocarpoides and Stylopandalus) are represented by single species each. The genera, Plesionika and Heterocarpus are represented by eleven and seven species respectively. Plesionika adensameri (Balss, 1914) a deep-sea shrimp hitherto unreported from Indian waters is recorded from west coast of India. Information on some biological aspects of few Pandalid shrimps from Indian waters is also reported in the present paper

Appraisal of Marine Fisheries of Kerala

Kerala ranks first in marine fish production of India forming nearly 25% (avg. 5.75 lakh tonnes) of the total annual production. The annual export of marine products from the state yields to the nation a foreign exchange of Rs. 1100 crores. There has been spectacular growth in the marine fisheries sector of the state due to fisheries friendly government policies, well developed harvest and post harvest infrastructure and increased demand for sea food both in the domestic and export markets. Kerala has been in the forefront in absorbing innovative and new technologies in fishing practices, which has led marine fisheries to take a complex structure
