the aim of this study was to determine the fatty acid and mineral composition in bone of 3 pelagic fish: gold stripe sardine (sardinella gibbosa), anchovy kilka (clupeonella engrauliformis) and indian anchovy (stolephorus indicus). fatty acid profiles showed that total saturated fatty acid have no significant differences in 3 species. the content of total mono saturated fatty acids in anchovy k...

the silversides or sand smelts are found in coastal areas of temperate to tropical seas and in fresh water. there are about 14 genera and 68 species with only one native species in the caspian sea basin, atherina caspia . in this review, the systematics, morphology, distribution, biology, economic importance and conservation of the caspian silverside of iran are described, the species is illust...

Seasonal and long-term variability of phytoplankton in the Middle Caspian was studied based on remote sensing data sea by SeaWiFS MODIS-Aqua scanners 1998–2021 results field observations 2004–2021. The seasonal chlorophyll “a” (CHL) calculated from satellite using a regional algorithm indicated that autumn winter seasons were main production periods year. In summer, period stagnation observed g...

Habitat preferences and foraging strategies affect population-level space use are therefore crucial to understanding population change implementing spatial conservation management actions. We investigated the breeding season habitat preference site fidelity of under-studied threatened, Baltic Sea Caspian Terns (Hydroprogne caspia). Using GPS devices, we tracked 20 adult individuals at two colon...
