Marine fishery resources of Orissa-An overview

Orissa has a coastline of 480 Km which constitutes about 6% of the coast of India. According to an estimate by CMFRI (2007), Orissa has a total of 57 marinefish landing centres, 641 fishing villages and about 1.21 lakh active fisherfolk who operate mechanised (3577 numbers), motorized (4719 numbers) and non-motorized (15444 numbers) fishing crafts. Exploratory surveys carried out along the northeast coast of India indicated that Orissa (Lat. 17.75°N to 22.5°N; Long. 81.5° to 87.6°E) is the most productive State in terms of bottom trawl fishery resources followed by Andhra Pradesh and WestBengal. This paper focuses on the catch trend of marine fisheries of Orissa with special emphasis on the gear-wise and resource-wise landings during 2005 and 2006 based on the data collected by Fishery Resources Assessment Division of CMFRI, Kochi and analysed through an Inhouse Research Project entitled ‘‘Appraisal of Marine Fisheries of Orissa’’

സമുദ്രത്തിനടിത്തട്ടിലെ മത്സ്യങ്ങള്‍ (Demersal finfish resources)

Fish based on their depthwise distribution may be grouped mainly as pelagic and demersal, the former occupying surface waters and the latter the neretic areas in the continental shelf. Demersal fish though generally occupy the sea floor, feeding on the benthic organisms and detritus, perform vertical and horizontal migration in search of their feeding and breeding grounds. Most of them lay their eggs in the surface waters or in the intermediate depths. The eggs after their larval phase return to the bottom to lead a demersal life

Demersal fishery resources of India - Winter School on Impact of Climate Change on Indian Marine Fisheries held at CMFRI, Cochin 18.1.2008 to 7.2.2008

The neritic waters along the continental shelf of the Indian EEZ is endowed with a rich abode of demersal finfish resources contributing to about 27.5 % of the total marine landings of the country. The demersal finfishes represented by a total of 23 groups and 71 commercially important species by virtue of their multifarious uses contribute substantially both as a protein supplement and to the revenue generation of the nation. Besides, the island ecosystems of Lakshadweep and Andaman & Nicobar have rich potential of marine ornamental fish resources, which by their aesthetic value are very much in demand for aqariculture both in India and abroad. Nevertheless, these invaluable fishery resources are subjected to wider fluctuations and/or depletion because of the adversities caused both by fishery related and non-fishery related factors. The prospects and problems of demersal finfish fishery in India are examined here with possible managerial measures so as to sustain the fishery

Demersal fishery resources of India – an update- Winter School on Towards Ecosystem Based Management of Marine Fisheries – Building Mass Balance Trophic and Simulation Models

The continental shelf of Indian EEZ extending upto 200 m depth is a rich abode of a variety of demersal finfish resources contributing substantially to the total marine fish production in the country. The major demersal fin fish resources are the elasmobranchs, major perches, catfishes, threadfin breams, silverbellies, sciaenids, lizardfishes, pomfrets ,bulls eye, flatfishes, goatfish and white fish. A review of the literature shows that the demersal fisheries in India had been growing in a phased manner during the past 5 decades thanks to the development envisaged through different 5 year plans since the country`s attaining independence. On the flip side we have several issues adversely affecting the increase in production of the resources such as growth overfishing, recruitment overfishing,increased operation of units through multiday fishing, scraping the benthic biota etc.In this chapter, an attempt is made to examine the present status and future needs of the demersal fisheries sector of India

On the occurrence of Decapterus macrosoma in trawl catches at fisheries harbour, Cochin

The scads (Decapterus spp.) locally known as 'Thiriyan' forms an important carangid fishery in 'trawls' at Fisheries Harbour, Cochin contributing about 45.09 and 60.67 % of the carangids caught in trawls during 1987 and 1988 respectively. D. macrosoma contributed upto 50% of the catches with the maximum catch per effort of 44.50 kg. This species represented by an abundant catch of juveniles and sub adults also contributing upto an estimated catch of 2,941 kg (catch/effort: 17 kg)
