Abstract
The demersal discard fauna of bottom trawl in the Strait of Sicily is varied and consisting of more than 221 species occupying different sub-strata at a depth ranging from 0 to 800 m (IRMA-CNR,1996). Although in the last decade the discard demersal community in this area was studied (Andaloro, 1985; Bono et al., 1992; Andreoli et al., 1995) the knowledge of the site assemblages is limited. During the Spring 2001, a statistical survey based on the method of "stratified sampling in space" was carried out. The most common diversity indices were used: Richness (S), Shannon-Wiener (H), Simpson (d) and Pielou (univariate methods).File in questo prodotto:
