摘要

The spatial distribution and abundance of fish larvae are useful indicators to better understand the reproductive strategies of the species and to identify the possible spawning areas. This study defines the major composition patterns and the community structure of the ichthyoplankton assemblage in the Southern Tyrrhenian Sea and analyse the influence of environmental factors that control these patterns. Samples were taken along a wide coastal area of Sicily extending for 2300 km2 during early spring 2007, in 24 stations across 11 shelf-slope transects with a Bongo net. The larval fish community consisted of 2073 individuals, further to 2750 fish eggs; 33 species belonging to 17 families were identified. Myctophum punctatum was the most abundant species followed by Cyclothone braueri, Lampanyctus pusillus, Lampanyctus crocodilus, Hygophum hygomii and Notoscopelus bolini. The family most represented was Myctophidae followed by Gonostomatidae, Paralepididae, Bothidae, Stomiidae, Callyonimidae and Gobiidae. Ichthyoplanktonic community abundance and composition in the Southern Tyrrhenian Sea were strongly correlated with the environmental factors, like bottom depth, salinity, temperature and fluorescence. Two different areas were highlighted as oceanographic constrains, grouping together the westernmost and the easternmost stations, that resulted influenced by different water masses. Different species assemblages between the two areas were also identified.
