Pelagic bacteria / micro-organisms
Bacterioplankton samples were collected by Niskin bottles at standard depths, from the oxygenated layer. The bacteria were grown on an agar medium 2216E, at temperature equal to the temperature of the sea water at sampling. Cells in the early to middle growth phase were fixed with paraformaldehyde solution consisting of 15% paraformaldehyde (TAAB, Aldermaston, England) in phosphate-buffered saline (3? PBS [per liter]: 24 g of NaCl, 0.6 g of KCl, 4.32 g of Na2HPO4, 0.72 g of KH2PO4 [pH 7.4]). Aft no

Phytoplankton
Phytoplankton samples (standard depths: 0, 10, 15, 25, 50,75, 100,150 m) were preserved by formaldehyde (4%) or Lugol solution and concentrated by gravitational sinking. The indentification of species and cell counting was performed under light microscope (Nicon) in Sedgwick-Rafter counting chamber, by the protocol of Suornia (1978), vertical profiles, Samples-130. no

Zooplankton
\nZooplankton samples were collected with vertical closing plankton net ?Jeddy? - 36cm. diameter, and 150μm mesh size. The species abundance was accomplished according to Dimov's method (Dimov, I., 1959). Individual standard species weights were used for calculations of biomass in milligrams per cubic meter (Petipa, 1959), vertical profiles, Samples-80.\n no

Eggs/larvae
Ichthyoplankton samples were collected with ring net d= 38 cm. diameter, and 150μm mesh size. The fish larvae and eggs were identified in laboratory. Abundance expressed in ind.m-2 was calculated. Samples-20. no

Zoobenthos
\nVan Veen grab with sampling area 0.1m? was employed for collection of quantitative macrozoobententhic samples. The samples were checked for adequacy ? the grab should penetrate to a digging depth of at least 10 cm. (20 better) and contain about 4l of sediment (Gray et al 1992). Samples-27.\n no
