Fish, a natural resource, has received great attention from all over the world. since it provides a cheap protein, employment and income to the millions of people for centuries. So fishermen, industrialist and multinationals are trying to exploit the marine resources to their maximum benefit by using modern craft, advance fishing equipments and efficient gear. Fishery resources in the open system particularly in oceans, were considered to be unlimited. However, recent developments in the innovation of efficient craft and gear using well tested material fitted with modern equipments that have greatly enhanced the mobility of craft, agility of gear and the ability of equipments to locate fishery resources have proved otherwise. Hence as the exploitation increases with more effort entering the fishery, the catch per unit of fishing effort starts to decline due to the limitness of the resources. The heavy fishing pressure in the recent past led to commercial extinction of a number of stocks such as. the North Sea herring, California sardine, Japanese Sardine and Peruvian anchovy (FAO. 1968: Gulland, 1974). In India, seer fish from Palk-Bay declined due to uncontrolled fishing (Devaraj 1983).

The present study focuses on the biochemical aspects of six islands belonging to Lakshadweep Archipelago – namely Kavaratti, Kadamath, Kiltan, Androth, Agathy and Minicoy. Lakshadweep, which is an area biologically significant due to isolation from the major coastline, remains as one of the least studied areas in Indian Ocean. The work, processed out the distributional pattern of trace metals among the biotic (corols, sea weeds and sea grass) and abiotic component (sediments) of ecosystem. An effort is made to picturise the spatial distribution pattern of different forms of nitrogen and phosphorus in the various sedimentary environments of the study area. Studies on the biogeochemical and nutrient aspects of the concerned study area scanty. In Lakshadweep, the local life is very dependent on reefs and its resources. The important stress which produce a threatening effort on the existence for coral reefs are anthropogenic-namely-organic and inorganic pollution from sewage, agricultural and industrial waters, sediment damage from excessive land cleaning, and over exploitation particularly through destructive fishing methods. In addition these one other more localized or less service anthropogenic stress: pollution by oil and other hydrocarbons, complex organic molecular and heavy metal pollution, and destructive engineering practices.

The overall focus of the thesis involves Studies on the riverine fishing geara of central kerala.Rivers and reservoirs of India harbour a rich and varied spectrum of fishes exceeding 400 species, which include commercially important fishes.The fish and fisheries play a crucial role in kerala's economy,employment generation ,food security and well being of its people.In the present study ,results of investigations conducted during 2001-2002 on riverine fishing gears of central kerala are presented along with detailed description of fishing gears,their distribution and operation covering aspects of selectivity and operational economics.Chapter I gives an introduction to the topiC of the study highlighting the relevance of the study and reviews of the existing literature on fishing gears and practices in riverine sector and sets out objectives of the study.The chapter 11 deals with the Materials and Methods used for the conduct of the investigations. In this chapter the area and the rivers selected for the study. reasons for the selection process and methodologies used for survey of riverine fishing gaear and investigations on design, structure and operation of different gear systems are presented.The chapter III discusses gillnet and its operation. Gill netting is one of the simplest and oldest methods of fishing. They are the most widely operated fishing gear in the rivers of Central Kerala. Gill netting being a low cost fishing method is of special interest for artisanal fisheries. Twenty different types of gillnets are operated in this sector.Chapter IV deals with cast nets. The origin and evolution of cast net has been briefly described in the introductory part.The chapter V deals with fishing lines, traps and other miscellaneous gears.This findings will be useful for riverine fishermen for deployment of appropriate gear systems during different seasons to ensure profitability of fishing operations.

This work is a study on ‘Legal Control of Fishing Industry in Kerala.Fishery and Fishery-related legislations are sought to be examined in the light of scientific opinion and judicial decisionsThis work is divided into five Part.The thrust of time Study is on the success of legislative measures in attempting to achieve socio-economic justice for the fishermen community.Fishing is more an avocation than an industry. It is basically the avocation of the artisanal or traditional fishermen who depend on it for their livelihood. As an ‘industry’, it is a generator of employment, income and wealth.The modern tendency in national legislations is to integrate legal proivisions relating to EEZ fisheries into the general fisheries legislation.Chartered fishing was introduced by the Central Government during 1977-78 to establish the abundance and distribution of fishery resources in Indian EEZ, for transfer of technology and for related purposes.Going by the provisions of Articles 61 and 62 of the U.N. Convention on the Law of the Sea, 1982, foreign fishing need be permitted in our EEZ area only if there is any surplus left after meeting our national requirements.Conservation of the renewable fishery resources should start with identification of the species, their habitats, feeding and breeding patterns, their classification and characteristics. Fishing patterns and their impact on different species and areas require to be examined and investigated.the Central Government, that the Kerala Marine Fishing Regulation Act, 1980 was passed.our traditional fishermen that our Governments in power in Kerala resorted to the appointment of Commissions after Commissions to enquire into the problems of resource management and conservation of the resources. The implementation of the recommendations of these Commissions is the need of the times.General infrastructure has increased to a certain extent in the fishery villages; but it is more the result of the development efforts of the State rather than due to increase in earnings from fishing. Fisherwomen ar e still unable to enjoy the status and role expected of them in the society and the family.Around 120 million people around the tuorld are economically dependent on fisheries. In developing countries like India, small-scale fishers are also the primary suppliers of fish, particularly for local consumption. A most important role of the fisheries sector is as a source of domestically produced food. Fish, as a food item, is a nutrient and it has great medicinal value.Consumers in our country face a dramatic rise in fish prices as our ‘fishing industry’ is linked with lucrative markets in industrial countries. Autonomy of States should be attempted to be maintained to the extent possible with the help and co-operation of the Centre. Regional co-operation of the coastal states interse and with the Centre should be attempted to be achieved under the leadership of the Centre in matters of regional concern. At time national level, a ifisheries management policy and plan should be framed in conformity with the national economic policies and plans as also keeping pace with the local and regional needs and priorities. Any such policy, plan and legislation should strive to achieve sustainability of the resources as well as support to the subsistence sector.

The present scenario of industrial fishing in India is that most of large trawlers are based at Visakhapatnam and congregate in the potential shrimp ground in the upper East coast of India commonly known as the Sandheads. These are outriggcr vessels operating two or four trawl nets along with a testing trawl called try net. In the early Seventies these vessels were operating on a very high economic return which was evident from the steady increase in number of outriggers over a period of twenty years. Since the total allowable catch has to be shared by all vessels including the increasing fleet, reduction per vessel output is bound to happen. Therefore some of them could not survive the competition and withdrew from the scene. The number of outriggers did not increase subsequently. However, there arose a doubt whether the existing fleet of about 180 vessels are fishing economically or whether there is any scope for further introduction of industrial vessels in the region. This study is focussing to the techno economic aspects of industrial fishing in the upper East coast of India

Reducing fishing pressure in coastal waters is the need of the day in the Indian marine fisheries sector of the country which is fast changing from a mere vocational activity to a capital intensive industry. It requires continuous monitoring of the resource exploitation through a scientifically acceptable methodology, data on production of each species stock, the number and characteristics of the fishing gears of the fleet, various biological characteristics of each stock, the impact of fishing on the environment and the role of fishery—independent on availability and abundance. Besides this, there are issues relating to capabilities in stock assessment, taxonomy research, biodiversity, conservation and fisheries management. Generation of reliable data base over a fixed time frame, their analysis and interpretation are necessary before drawing conclusions on the stock size, maximum sustainable yield, maximum economic yield and to further implement various fishing regulatory measures. India being a signatory to several treaties and conventions, is obliged to carry out assessments of the exploited stocks and manage them at sustainable levels. Besides, the nation is bound by its obligation of protein food security to people and livelihood security to those engaged in marine fishing related activities. Also, there are regional variabilities in fishing technology and fishery resources. All these make it mandatory for India to continue and strengthen its marine capture fisheries research in general and deep sea fisheries in particular. Against this background, an attempt is made to strengthen the deep sea fish biodiversity and also to generate data on the distribution, abundance, catch per unit effort of fishery resources available beyond 200 m in the EEZ of southwest coast ofIndia and also unravel some of the aspects of life history traits of potentially important non conventional fish species inhabiting in the depth beyond 200 m. This study was carried out as part of the Project on Stock Assessment and Biology of Deep Sea Fishes of Indian EEZ (MoES, Govt. of India).

Induction of growth in the primary marine fishing industry of Kerala is a sine gua Qgn for improving the economy of the fishermen, the state's domestic product as well as earning more foreign exchange for the country. The State Administration has been trying to instil growth into the industry eversince the output of the industry showed marked sign of decline (particularly after 1975). Significantly, it has attempted to strengthen the traditional sector, (which is considered to be the crucial sector of the primary marine fishing industry of the state) by introducing intermediate technology and by revamping the organisational structure of the industry. But it appears that the production system in the primary marine fishing industry of Kerala has been severely constrained by the existing technology, organisation of production and marketing institutions. Regeneration of growth in the industry calls forth an understanding of the 'process' of growth in the industry and the need to réorganise it with new technology, and new organisations. The present study is an attempt to unraval the process of growth in the primary marine fishing industry of Kerala since 1951
