Seasonal and temporal trends in metrics of fish community for otter-trawl discards in a Mediterranean ecosystem.–ICES Journal of Marine Science, 65: 539–550. Trends in discard to marketed ratios, size spectra, diversities, and trophic levels of the demersal fish community were examined using data from a seasonally closed commercial trawl fishery in the eastern Mediterranean Sea (Ionian Sea), over a period of about 10 years.

Data from pelagic trawl hauls, multivariate methods, certain satellite environmental data and area topographic characteristics were used in order to identify the parameters that could discriminate the spatial distribution of the juveniles and the adults, of both species.

Spawning stock biomass (SSB) based on the DEPM was 40042 t in 2003 and 22799 t in 2004. Stock biomass based on acoustics was 47838 t in 2003 and 46508 t
