Abstract

The organisms that live on, or in, the bottom of a water body with >1.0mm size are known as macrobenthic organisms which mainly consists of different invertebrates viz., molluscs, cnidarians, crustaceans, sponges, worms, etc. Benthic invertebrates play an important role in transitional ecosystems, by filtering phytoplankton and then acting as a food source for larger organisms such as fish, thereby linking primary production with higher trophic levels. They also structure and oxygenate the bottom by reworking sediments and play a fundamental role in breaking down organic material before bacterial remineralization.

They are occasional visitors of brackish waters, bays, coastal reefs, etc. They are one of the important food fishes. The family sparidae has about 129 species in 35 genera in Worldwide (Froese & Patily, 2010). The extensive literature stirvey on fish records of Indian coast shows records of 9 species from 7 genera in Indian waters (Talwar & Kacker, 1984; Froese & Pauly, 2010). During the surveys at Digha coast, authors have come across one specimen of the family Sparidae and after Close observation of distinguishing features, the specimen is identified as Argyrops bleekeri (Oshima, 1927), King Soldier Bream.

Abstract

Digha (Lat 21°36' Long 87°30') is one of the major marine fish landing stations of the east cost of hidia. Considering the importance of fish faunal resources, several efforts were made regarding incidences of ichthyofauna of region. The most recent compilation of ichthyofaima of the region contributes 212 species from 145 genera & 88 families (Chatterjee et al, 2000). There were also previous reports of 238 species from 72 families (Manna and Goswami, 1985; Goswami, 1992).
