A biomass of 1.5 g Gammarus with an average length of 7 ± 0.25 mm was transferred to the glass aquaria with volume 900 cm3 (volume 2.5 l). The Gammarus were fed with diets include baked potato (treatment 1), 30 percent yeast and 70 percent potato, (treatment 2), 50 yeast percent and 50 percent potato (treatment 3), no feeding (treatment 4) at rate of 6 to 7 percent of total biomass for 45 days. Results showed that the total production rate (adult and baby), specific growth rate and population doubling time were significantly high in treatments 2 and 3(P > 0.05). The biomass and daily growth rate were significantly higher than yeast fed Gammarus (P> 0.05). Additionally Gammarus in treatment 3 had the highest food conversion ratio. The results of the present study showed that the administration of yeast in diet can improve Gammarus growth rate under culture conditions.

In this study, the effects of mono and mixed algal diet (Chaetoceros calcitrans, C. muelleri, Isochrysis galbana, Tetraselmis suecica and Chlorella vulgaris) on the larval metamorphosis of the barnacle Amphibalanus amphitrite were evaluated. Larvae obtained from A. amphitrite were cultured in six-well plate on a daily algal food at cell concentration of 2 × 105 cell/L. One-Way ANOVA and Tukey’s test indicated significant differences among the metamorphose rates of the larvae reared at different algal diet (p<0/05). Larvae fed with mono (except T. suecica) and mixed algal diet developed into cyprids within five days while those fed with T. suecica developed into cyprids after 6 days. There was higher percentage of metamorphosis in larvae fed with the mixed diet of C. calcitrans and T. suecica. Our results showed that mixed algal diets especially when diatoms are present shorten naupliar duration and increase metamorphosis success to cypris stage.

Among animal species, fishes are the inhabitants that cannot escape from the harmful effects of these contaminants. In the present research, during spring 2014, twenty-nine specimens of Liza aurata were collected from Bandar Anzali coast in Gilan province. The aim of this study was to provide information on heavy metal (Cd and Pb) concentrations in the muscles of this fish species and to evaluate the possible risk associated with their consumption. The levels of heavy metals were measured by GFAAS after digestion of the samples using concentrated acids. The results of this study showed that the average concentrations of cadmium and lead in muscle were 0.67 and 0.072 µg/g, respectively. The concentration of two metals in the present research were lower than the limits permitted by FAO, WHO, MAFF and NHMRC. The estimated daily intakes (EDI) of two metals through consumption of the Liza aurata fish by native people in the Bandar Anzali coast were well below the permissible tolerable daily intake for 70 kg person (PTDI70) set by EPA. Therefore, it can be concluded that no problems on human health would be raised at present from the consumption of Liza aurata fish from the Bandar Anzali coasts.

Therefore, it is important to introduce and replace new sources of drug such as medicinal plants with antimicrobial properties. The aim of the present sturdy was to evaluate the antibacterial effects of areal parts extract of Epilobium species collected from Iran. The results revealed that extract of all species studied, except (E. roseum subsp. subsessile) could inhibit the growth of bacteria. Based on our results, gram positive test bacteria showed the most susceptibility to the extracts compared to gram negative ones. None of the extracts could affect the growth of Pseudomonas aeruginosa and Enterococcus faecalis. We found that the willow herb extract inhibited the growth of bacteria in culture more effectively than related common antibiotics. Given that aerial parts of plant extract was utilized for this study, further investigation is recommended to determine which specific part of the plant (i.e., leaves, stem, and flowers) possess the antibacterial properties.

Mean concentration of lead was estimated in sediment and also in three groups of macrobenthose in five areas in coast of Bandar Abbass. Results showed that the mean concentration of the Lead in sediments was from 0.359 ppm in Goorsozan estuary to 0.216 ppm in Posht-e-Shahr. Lead concentration in crab was maximum in Goorsoozan estuary with 0.470 ppm and minimum in Posht-e-shahr with 0.270 ppm. Bivalvia with 0.300 ppm in Bahonar Jetty and 0.250 ppm in Goorsoozan estuary obtained maximum and minimum concentration of Lead, respectively. Gastropoda obtained 0.150 ppm of Pb in Getty Bahonar and 0.039 ppm in Goorsoozan estuary. The results confirmed that Lead concentration was in order of Crabs > Gastropoda > Bivalvia. Spatial comparison of Lead concentration showed that sediment and crabs obtained high concentration of Lead in Goorsoozan estuary, while Gastropoda and Bivalvia obtained high concentration of Lead in Jetty Bahonar. The significant coefficient of Lead concentration between sediment and crab indicated that crabs bioaccumulate Lead from sediment directly but lack of significant coefficient between Gastropoda and Bivalvia with sediment showed these organisms bioaccumulate Lead from other sources of sediment for instance water.
