Synergistic Effects of Selenium and Magnesium Nanoparticles on Growth, Digestive Enzymes, Some Serum Biochemical Parameters and Immunity of Asian Sea Bass (Lates calcarifer).

This study aimed to investigate the effect of selenium and magnesium nanoparticles and their combination on growth, serum biochemical and immune parameters, serum hepatic enzymes, and digestive enzymes in Asian Sea bass (Lates calcarifer), with an average weight of 32.78 ± 1.16 g for 42 days.

Changes in serum biochemical parameters and digestive enzyme activity of juvenile sobaity sea bream (Sparidentex hasta) in response to partial replacement of dietary fish meal with poultry by-product meal.

A 60-day experiment was conducted to evaluate the effect of dietary fish meal (FM) replacement with poultry by-product meal (PBM) on digestive enzymes, non-specific serum enzyme activity, and serum biochemical parameters of juvenile sobaity sea bream, Sparidentex hasta, weighing 29.27 ± 0.06 g.

Use of Solen brevis as a biomonitor for Cd, Pb and Zn on the intertidal zones of Bushehr-Persian Gulf, Iran.

The concentrations of Zn, Cd and Pb were determined in tissues (shell and soft tissue) of 144 of bivalve mollusks (Solen brevis) and 15 samples of surface sediment collected from three locations in intertidal zones of Bushehr coast, Persian Gulf, Iran in May 2011. The mean concentrations of Zn, Cd and Pb in the sediment samples were 26.2, 1.

Application of biotic indices in assessing the ecological quality status of Bahrekan estuary (Persian Gulf).

The aim of present study was to examine the macro invertebrates as an assessment tool for characterization of the state of Bahrekan estuary in Persian Gulf, by using different biotic indices. An investigation on benthos was carried out during autumn 2008 to summer 2009 in the Bahrekan estuary (Persian Gulf). In order to identify and assess the benthic community structure, seasonal sampling was done from 21 stations with three replicates using van veen grab (.

Morphology of the zoeal stages of Hexapus sexpes fabricius, 1798 (decapoda, brachyura, hexapodidae) reared in the laboratory.

Abstract: The present information is based on the study of the zoeal stages of Hexapus sexpes. A single ovigerous female of Hexapus sexpes was collected from the North West Persian Gulf (29 degrees 56'14"S, 49 degrees 0288"W) in April 2009. Female was maintained in aquarium containing natural sea water at 25 degrees C until the eggs hatched.
