Abstract

Fish diversity (77 species) in the Aghanashini River estuary of the Indian west coast is linked to variable salinity conditions and zones I, II and III for high, medium and low salinity respectively. Zone I, the junction between Arabian Sea and the estuary, had all species in yearly succession - due to freshwater conditions in monsoon to high salinity in pre-monsoon. The medium (zone II) and low (zone III) salinity mid and upstream portions had maximum of 67 and 39 fish species respectively. Maintenance of natural salinity regimes in estuary, among other ecological factors, is critical for its fish diversity.

Abstract

While conducting fishery resource surveys and efficiency studies on estuarine fishing gears of West Bengal during 2002-03 and 2003-04, an attempt was made to inventorise indigenous fishing gears of Hooghly-Matia estuarine ecosystems of West Bengal. This forms the basis of the present communication. In 1906, Sir K. G. Gupta (1908) undertook investigations on the fisheries of the province of Bengal. Since then, several workers have studied the fish and fisheries resources of Hooghly-Matla estuaries (Hora, 1949; Pillay and Ghosh, 1962; Saha, 1970; Mitra et al, 1997; Pramanik and Nandi, 2004). However, very little work is done on fishing gears of this region (Saha, 1970).

Abstract

Chilled seafood is preferred by consumers over frozen products as they are being the closest in freshness and quality to landed catch. Chilled pomfret is an important export product of 'chilled items', one of the 12 major export item groups of marine products exported from India. The export performance of chilled pomfret was analysed by studying the graphical trend, percentage contribution, compound growth rate analysis, instability index, and direction of trade. Singapore was the major buyer in terms of export quantity taking more than half the average production (57%), followed by Malaysia (21%) and Kuwait (11%). The growth rate of chilled pomfret in export quantity to Singapore was negative (-7.40%) and was significant. The instability index of export quantity and real value was moderate to high among the major countries. Direction of trade analysis revealed that only Kuwait had a high probability of retention of previous market share (0.7234). There appeared to be diversion of raw material to newer products. Measures must be taken to increase chilled pomfret exports by regaining Singapore market and exploring new markets.

Abstract

Chilled fish is one of the largest export products among chilled items, one of the 12 major export item groups of marine products from India. The export performance of chilled fish in the post liberalisation period 1995-2008 was analysed by studying the graphical trend, percentage contribution, compound growth rate analysis, instability index and direction of trade. The decline of Singapore as the bulk purchaser, the emergence of a number of smaller markets, and the increase in total export quantities were the dominant features of the trade in chilled fish. Growth rate of Singapore in export quantity and export real value was negative and was significant. Growth of Thailand in export quantity and value was moderate and significant. Stability in export quantity was lower for U.A.E., higher for Canada and moderate for Singapore, Thailand and Hong Kong. Considering direction of trade, Thailand showed only a moderate probability (0.3690) of market retention while Singapore had probability of becoming unstable.
