Abstract
We determined bioaccumulation of heavy metals (Cd, Pb, Ni and Hg) in the muscle, gill and liver organs of Barbus xanthopterus in summer 2009 in Karoon River, south west of Iran. Gill net was used to sample 48 random size fish specimens from Karoon River downward of Ahwaz city (Shekariyeh 3 village). The tissues were extracted and the elements were determined using atomic absorption spectrophotometer. Concentrations of heavy metals Cd, Pb, Ni , Hg in muscle tissue of Barbus xanthopterus were 1.679, 2.37, 1.16, 1.29mg/kg dry wt and in gill were 2.17, 2.92, 1.44, 1.34mg/kg dry wt and in liver were 1.92, 2.79, 1.31, 1.43mg/kg dry wt, respectively. All the results were statistically significant (P 0.05). The concentrations of heavy metals were higher than standards of the World Health Organization (WHO) in the muscle tissue of Barbus xanthopterus in Karoon River.

Abstract
A comparative study was conducted on concentration of heavy metals Hg, Cd and Pb in the muscle, liver and gill tissues of Liza abu in winter 2009, in Karoon and Bahmanshir Rivers of Khuzestan province. We used 216 specimens of Liza abu. Metals were extracted from the tissues using wet digestion method and concentration of the heavy metals was measured by Atomic Absorption Spectrophotometer. The highest concentration of Cd, Hg and Pb were measured at 0.540±0.264, 0.029±0.005 and 1.080±0.128mg/Kg dry weight respectively. The lowest concentration of Cd, Hg and Pb were found to be 0.434±0.035, 0.024±0.001 and 0.930±0.036mg/Kg dry weight, respectively. No significant differences in concentration of heavy metals Cd, Hg and Pb in the muscle, liver and gill of Liza abu from the Karoon and Bahmanshir Rivers were detected (P 0.05). Results showed accumulation of Hg and Cd was lower than the FDA standard but accumulation of Pb was higher than the WHO standard. *Corresponding author

Abstract
Effect of freezing on the chemical quality and fatty acid composition of cultured shrimp muscle, Litopenaus vannamei were investigated by measuring moisture content, ash, total protein content, total lipid content, fatty acid composition, and Thio barbituric Acid (TBA) during 6 month keeping in frozen storage at 18°C. According to the results, moisture content (75.93% to 73.10%), ash (1.5% to 2.07%), total protein content (25.3% to 20.87%) and total lipid content (0.83% to 0.23%) changed during six month of frozen storage. PUFA (45.21%) content was higher than the SFA (30.08%) and MUFA (19.32%) content. The poly chain unsaturated fatty acids, saturated fatty acids and mono chain unsaturated fatty acids in shrimp muscle were C18:2n6 (15.32%), C20:5n3 (9.68%), C22:6n3 (8.48%), C16:0(15.18%), C18:0 (13.04%) and C18:1n9 (15.32%), respectively. The thio barbituric acid values (TBA) ranged from 0.0065 to 0.35 mg malonaldehyde/kg during freezing storage. The lipid stability of shrimp muscle, were in acceptable limit during frozen storage for up to 6 month. *Corresponding author

Abstract
A comparative study was conducted on concentration of heavy metals including: Hg, Cd and Pb in the muscle of Otolithes ruber in Abadan and Bandar Abbas Ports in the Persian Gulf. In this study, a total of 42 specimens of Otolithes ruber were collected from coastal waters of Abadan and Bandar Abbas Ports in 2010. Heavy metals were extracted from the muscle tissues using wet digestion method and concentration of metals were measured by Atomic Absorption Spectrophotometer. The results showed that mean (±SD) accumulation of Hg, Cd and Pb in the muscles of Otolithes ruber in Bandar Abbas were 0.058±0.001, 0.279±0.056 and 0.668±0.077mgKg-1 wet weight, and in Abadan were 0.056±0.007, 0.25±0.038 and 0.638±0.087mgKg-1 wet weight respectively. No significant differences were found in concentrations of Hg, Cd and Pb in the muscle of Otolithes ruber between Abadan and Bandar Abbas ports. Accumulation of these metals were higher in the muscle of Otolithes ruber than that Bandar Abbas Port. Concentration of Hg in the muscle of Otolithes ruber was lower than acceptable limit suggested by WHO, MAFF, NHMRC. However concentrations of Pb and Cd were higher. *Corresponding author

Abstract
This study was evaluated the influence of different packaging: aerobic, vacuum and sil vacuum on shelf life grass carp (Ctenopharyngodon idella) in refrigerated temperature (4°C) by determine microbiological and chemical characteristics. Results showed that in all treatment PV values were did not increase of acceptability limit (10 meq/kg) during the storage and in aerobic packaging values of TVN (30.31±0.79 mg/100 g) that were above of acceptable limits. In sil vacuum and vacuum packaging, values of TBA were at acceptable limits during 15th and 9th days for aerobic packaging. In aerobic packaging, the value of TVC 7.80± 0.34 log cfu/ g in 12th and in all packaging in 15th were not at acceptable limits (9.06± 0.34 log cfu/ g in aerobic, 7.52± 0.26 log cfu/ g in vacuum and 7.04± 0.12 log cfu/ g in sil vacuum). Results indicated that the best shelf-life of grass carp fillets observed in sil vacuum and vacuum packaging in 12thduring, but sil vacuum than the better (p<0.05).

Abstract
The aim of this study was to determine the concentration of iron and Hazard quotient (HQ)in muscle of four marine fishes, orange - spotted grouper(Epinephelus coioides),yellow fin sea bream(Acanthopagrus latus), tongue fishes (Cynoglossus arel) ,silver pomfret(Pampus argenteus) and farmed carp fish, common carp(Cyprinus carpio), grass carp(Ctenopharyngodon idella), big head carp (Aristichthys nobilis) and silver carp(Hypophthalmichthys molitrix) from Khuzestan. Farmed fish sample was prepared from the Azadegan warm water fish culture center and marine fish was prepared from fishing ports Bahrkan, Abadan and Bandar Emam. Iron concentration measured by wet digestion and atomic absorption spectrometer Perkin Elmer 4100.The results showed the average of iron level in farmed fish was 17.08± 1.21 mg/kg dry weight and in marine fish was 10.68± 3.66 mg/kg dry weight (P <0.05).The results showed that the highest iron concentrations between farmed fish muscle was on big head carp equal to 18.16mg/kg dry weight and was significantly different(P <0.05) with grass carp and the highest iron concentrations between marine fish muscle was onTongue fishequal to15.50± 0.50mg/kg dry weight and was significantly different(P <0.05). Average hazard quotient in farmed fish was HQ=0.61and in marine fish was HQ =0.38. Hazard quotientin marine fish were in tongue fish HQ=0.55, yellow fin sea breamHQ =0. 3, Orange - spotted grouper HQ= 0.26 and silver pomfret HQ =0.41 and Hazard quotient in fish were in big head HQ=0.65, common carp HQ =0.63 grass carp HQ= 0.55and silver carp HQ =0.61. Hazard quotient in all samples was less than one and so fish nutrition no risk in terms of the amount of iron in the human body.
