| Abstract |
|
The biodiversity is not an entity in itself, but it refers to the intrinsic property and universal attribute of all living forms that each individual is unique [Solbrig, 2000]. The concept encompasses the variety of the world’s organisms together with the interrelatedness of genes, species and ecosystems that create the great, interdependent system of the life on earth. Genes, species and ecosystems reflect the different levels of complexity in biological organisation at which it is possible to measure biodiversity. The coastal lagoons are environments subjected to remarkable fluctuations in many characteristics such as salinity, temperature, nutrient concentration, hydrodynamic conditions. The lagoonal species have evolved a very wide tolerance to the environmental variation while the habitat availability and resource partitioning mainly affect their distribution patterns. These ecosystems are important sites for fish, as nursery areas, overwintering sites and migration areas, which naturally support large numbers of fish [Elliot & Hemingway, 2002]. The lagoon of Venice supports high fish production. The environmental variability and unpredictability select for a low diversity of resident fish, highly specialized to cope with the environmental changes, and for an high abundance of transient species [Mann, 2000; Elliot & Hemingway, 2002]. The knowledge of fish diversity can be used to assess both the conservation options and resource exploitation. This study presents a preliminary report on the fish fauna diversity in the lagoon of Venice at the species and community levels. Community attributes such as species composition, in terms of abundance, diversity and functional groups, have been investigated, while cytogenetic technics have been used to determine differences at the species level in the two most representative families (Syngnathidae and Gobiidae) of the lagoonal fish fauna.
