the objective of the present study was to determine chemical composition and fatty acid profile of common kilka ,clupeonella cultriventris caspia, in the caspian sea. the chemical analysis revealed that the protein and lipid content of common kilka were 15.05 and 6.5% of the fresh weight, and total mufa, pufa and sfa were found to be 37.00, 32.89 and 29.03% respectively. palmitic acid (16:0) am...

kilka fish are known as the main industrial and pelagic species of iran that are captured abundantly in the southern caspian sea. this study was conducted to survey the effectiveness of refinement steps on kilka (clupeonella delicatula) crude oil quality and fatty acid profiles. neutralization, bleaching, winterization and deodorization were performed on crude oil with deodorization done under ...

The Solnhofen Konservat-Lagerstätte yields a great number of remarkably preserved fossils eumalacostracan crustaceans that help us understand the early radiation several groups with modern representatives. One fossil from there, Francocaris grimmi Broili, 1917 is small shrimp-like crustacean originally described about 100 years ago as mysidacean (opossum shrimps and relatives) latest Kimmeridgi...

In the present study, some ecological factors were studied for Amphipoda at different depths. The Shannon, Margalef, and Hill indices were used to determine the  species diversity, richness and evenness, respectively. In addition, the association and niche overlap values were estimated. Indices of species richness and diversity were highest at 50 and 100m depths, respectively.  The ordination o...

In current study, protein hydrolysates were produced using microbial proteases of Alcalase, Protamex and Flavourzyme from by-products (head, skin and viscera) of Alosa (Alosa caspia), a major Clupeonella species in the Caspian Sea. The results indicated that the protein hydrolysate from Alcalase, had the highest protein content (78.91%), protein recovery (80.42%) and degree of hydrolysis (21.06...
