DESCRIPTION
The book finds its detailed treatment about the fish genetics and aquiculture and their correlation. The lan-' age of the book and the way of expression of the facts really deserve to be admired. The genetic improvement of fish for aquiculture and related fisheries is a field of research that has been immense advances in recent years. Yet there has been no book which provides an accessible overview of the subject until now. The present study investigates the seasonal variation in fish abundance, fish biomass, reproductive status and population sructure of four domain benthic fish species, Salaria pavo, Poniatoschistus marmoratus, Gobius cobitis and Gobius niger, in the shallow and littorl areas of the Mar Menor coastal lagoon. In addition, the seasonal habitat associations of each species were studied by assessing environmental variables related to the habitat structure: submerged vegetation cover, submerged vegetation density, water depth and substrate composition. The temporal variations in fish density, standing stock and size frequency distributions, of these species can largely be attributed to the seasonally of their breeding and juvenile recruitment periods. Moreover, habitat associations for these species were similar to those obtained in other Mediterranean and Atlantic coastal lagoons.
