On the occurrence of ichthyoplankton in the Saronikos Gulf, Aegean Sea, 1. Anchovy and sardines in 1969-1970-1971. ArchiMer
Yannopoulos, A; Yannopoulosa, C; Soteriades-vlahos, C.
The spawning and nursery grounds of 3 spp of commercial importance, Engraulis encrasicholus, Sardinella aurita and S. pilchardus were studied in the Saronikos Gulf during 1969, 1970 and 1971. The waters of the gulf are very rich due to turbulence caused by currents penetrating the gulf from the Aegean Sea. This turbulence causes bottom upwelling especially in the northern region which is shallower. At the height of their reproduction these fish represent 90-95 per cent of the entire ichthyoplankton, especially in the northern region. E. encrasicholus appears to be the most abundant sp with a maximum of 1099/m super(2) of surface waters (where the density of eggs = 536 and of larvae = 563). 232/m super(2) of surface water represents the maximum for S....
