In this study, the length-weight relationships (LWRs) and condition factors were estimated for 445 specimens belonging to three gobiid species viz. Ponticola bathybius (Kessler, 1877), Neogobius caspius (Eichwald, 1831) pallasi (Berg, 1916) from Southern Caspian Sea basin. Total length total weight of examined ranged 4.9-28.3 cm 0.64-263.4 g, respectively. The parameter b studied found between ...

Planktonic foraminifer oxygen isotopes through MIS 12 were analysed from Ocean Drilling Program Site 977 in the Alboran Sea. After correction of sea surface temperature (SST) effect on δ18O composition foraminiferal calcite, resulting seawater (δ18Ow) was used to reconstruct variations δ18Ow Atlantic inflow into Mediterranean. A synchronous record KC01B core, Ionian Sea, evaluate changes isotop...

the systematics, morphology, distribution, biology, economic importance and conservation of the freshwater eel ( anguilla anguilla ) of iran are described, the species is illustrated, and a bibliography on this fish in iran is provided. the species is found in the caspian sea basin as an exotic.

the systematics, morphology, distribution, biology, economic importance and conservation of the perches of iran are described, the species are illustrated, and a bibliography on these fishes in iran is provided. there are three species, perca fluviatilis , sander lucioperca and s. marinus , found naturally in the caspian sea basin, with s. lucioperca translocated.

Understanding the population structure and level of genetic diversity wild populations is fundamental for appropriate stock management species conservation. The common carp ( Cyprinus carpio ) one most important bony fish throughout Southern coastline Caspian Sea, but captures this have seen a dramatic reduction during last decade. As consequence, restocking program has been put in place to mai...

abstract many people know the important effects of caspian sea winds and storms on the economy of three provinces of iran including gilan, mazandaran, and golestan that they form one exclusive and extent area which have moderate and humid climate. this paper used a synoptic climatologically approach, which combine a number of atmospheric factors. using daily and monthly winds data including the...
