According to the results, 60 Genus and 6 phylum (11, 31, 10, 2, 1, 1, 1, 2 genus of phylum Protozoa, Rotatoria, Arthropoda, Gastrotricha, Mollusca, Tardigrada, Nematoda, Porifera, Annelida) respectively were identified. The results showed that the maximum annual average density of zooplankton was observed with 2497 ± 687number per litre in Karkan station and the population was more in the summer than in other seasons. Density of Rotatoria, protozoa and superclass Copepoda were 48%, 45% and 6% respectively. Results showed the population structure of zooplankton did not change much compared to past studies (due to improper environmental conditions), excluding Protozoa but the diversity of all zooplankton group is extremely declined. Kruskal Wallis test showed there was not significant difference between density of zooplankton in different stations, months and seasons (p>0.05), but significant differences were found between densities of different zooplankton phylum (p<0.05).}, Keywords = {Zooplankton, Anzali wetland, Density, Diversity }, volume = {24}, Number = {2}, pages = {29-41}, publisher = {IFSRI}, doi = {10.22092/ISFJ.2015.103127}, url = {http://isfj.ir/article-1-1396-en.html}, eprint = {http://isfj.ir/article-1-1396-en.pdf}, journal = {ISFJ}, issn = {1026-1354}, eissn = {2322-5998}, year = {2015} } @article{ author = {Dorafshan, S. and Shojaee, N. and Mirghaffari, N.}, title = {Heavy metals (Cd and Cr) concentration in different tissues (muscle, gill, kidney and intestine) of Zayandehrood chub, Petroleuciscus esfahani}, abstract ={The aim of this study was to evaluate two heavy metals (Cd and Cr) concentrations in different tissues including muscle, gill, kidney and intestine of Zayandehrood chub, Petroleuciscus esfahani in different stations along the Zayandehrood River.

Following measuring LC50-96h of cadmium (43.679 mg/l) for this species, 80 common carp were exposed to 10 different treatments, including control, acute (43.68 mg/l), sub-lethal (21.84 mg/l) and chronic (4.37 mg/l) cadmium as well as hypoxia for immediately (20% of saturation), 24h (40%) and 7 days (60%), and joint exposure of each similar treatment. By using of respirometer technique, we measured oxygen consumption rate in different time spans to calculate each individual standard metabolic rate (SMR), maximum metabolic rate (MMR), aerobic scope (AS), factorial aerobic scope (FAS) and critical oxygen tension (PCrit). Obtained data show that acute and sub-lethal cadmium treatments led to significant (P<0.05) increases in all metabolic indices in comparison with control group whilst the MMR and AS have been reduced (P<0.05) following hypoxia treatments. Combined treatments of hypoxia and cadmium led to reduce SMR and PCrit in all treatments and MMR, AS and FAS only in acute and sub-lethal treatments.

The products were packed under atmospheric and vacuum conditions. The results showed that there were no effects on sensory attributes, microbial load, pH and FFA.

Pearson analysis revealed direct correlation between abundance of Goniaulax polyedra, Goniaulax digitale and trophic index. In the other words, higher abundance of the two species decreased the water quality.
