Variety and frequency of Ascidians were studied seasonally (during four seasons through 2010-2011) in five different transects around the Khark Island. In each transect three stations were sampled in high-tide, mid-tide and low-tide, at each sampling period, environmental factors such as temperature, salinity and total organic maters (TOM) were measured. In this study only one species (Pyura vittata) was indentified in the area. This species was only observed in spring (2 in a square meter) and fall (1 in square meter) and in midtide level in the northern part of the Khark Island. Pyura vittata unlike other species of Ascidiacea has more strength and capability to environmental changes, physical conditions and pollution compare to other Ascidiacea species. The main reason for reducing the density and diversity of Ascidiacea is this region, probably is oil pollution.

To determine levels of some hematological and biochemical factors in cultured bighead carp 80 specimens of 9, 12, 24 and 36 months old were collected from aquaculture center in Rasht, Giulan Province and hematological sampling were done from their caudal fin and then were analyzed. In this study, statistical analyzes showed that by increasing of age, the level of cholesterol and neutrophile were increased and in each age groups has significant difference (P<0.05). The amount of glucose, hemoglobin (Hb) and hematocrit (HCT) in 12-month group were increased and compared to other age groups has significant statistical difference (P<0.05). Average amounts of hemoglobin concentration of globules (MCHC) and the numbers of red globules (RBC) in 24-month age group were increased and have significant difference (P< 0.05). The amount of triglyceride, protein, calcium, average amount of the weight of globular hemoglobin (MCH) in 36-month age group compared to other age groups were increased and have significant differences (P<0.05). The level of non-organic phosphorus in 9-month age group with other age groups was increased which has significant difference (P<0.05). But in other parameters including: The number of phagocytes, the number of lymphocytes (Lym) and monocytes (Mon), it has not significant difference (P>0.05).

Gastropods are one of the most important Benthos in the aquatic ecosystems and have major role in food chain. The gastropod samples were collected from 4 stations of Daier, Deylam, Bushehr and Kangan ports in the north-west of the Persian Gulf with three replicates in spring and summer. Sampling was carried out by using quadrate and then gastropods were identified. For assessing the species diversity and to determine the dominant species of gastropods, the Shannon and Simpson indices were estimated. In this study, 14 species belong to 12 genera were identified. The results indicated that the highest Shannon index was found in spring in Daier port with H=1.557 and the lowest value was in spring in Kangan port with H=0.615. The highest and the lowest Sympson index was estimated in summer in Kangan station with λ=0.621 and in spring in Daier station with λ=0.264, respectively. Also the highest and the lowest species diversity of gastropods were in Bushehr and Kagan stations, respectively. Results showed, in summer, by increasing temperature, the abundance of gastropods was decreased. Also it is noteworthy to mention that the Turritella fultoni species was found in all stations.

This study was conducted to evaluate the effects of feeding with spirulina on immunity system in catfish, Pangasius hypophtalamus. For this purpose, totally 112 fish were randomly distributed in to 5 glass aquaria (20 fish/tank). The experiment was conducted in 4 treatment and 1 control group. Five diets containing varying levels of spirulina (0,2.5, 5, 7.5, 10%) were prepared and fed to the fish five times a day to 3% of their body weight during 35 days. At the end of the experiment period, blood samples were taken by cutting the caudal peduncle of fish at the level of anus. Blood samples were analyzed with routine methods used in fish hematology and following parameters were measured: White blood cell count (WBC) and leucocyte differential count. According to the results, no significant difference was observed between white blood cells count (WBC), monocyte and neutrophil treatments. But significant differences were observed in lymphocyte between treatment compared to control group (P≤0.05), and the largest number was recorded in control group. The result showed that using different treatments of Spirulina platensis probably had no effect on the specific – immune system in Pangasius hypophtalamus but increased numbers of neutrophils. Increasing the numbers of neutrophil are showing effect of spirulina on phagocytosis and improvement of immune system in this species.

Effect of dietary mannan oligosaccharide (MOS; activeMOS® ) on growth, survival, body composition and some hematological parameters in carp juvenile (Cyprinus carpio) were investigated for 45 days. Basal diet were supplemented with 0 (control), 1.0, 2.0 and 3.0g kg-1 MOS in a totally randomized design trial in triplicate groups. The experiment carried out in 100 liters PVC tanks. 20 juvenile carp with initially average weight 1.3±0.17g were stocked in tanks and fed up. There were no significant differences in growth and feeding parameters between fish fed control and MOS supplementation diets (P>0.05).The highest and the lowest growth performance were observed in 1.0g kg-1 MOS and control treatment, respectively. There were no significant differences in survival rate among experimental groups (P>0.05). No significance difference was observed in body composition, but in group fed with 1.0g kg-1 MOS showed higher protein carcass (P>0.05) than other group. An elevation of haematocrit, lymphocyte (p<0.05), WBC, RBC, Hb, eosinophil and neutrophil (P>0.05) were found in the fish fed by 1.0g kg-1 MOS. The result indicated that 1.0g kg-1 MOS can improved growth performance, survival, final production and some blood parameters of carp juvenile and it is appropriate for supplementation in the diet of cultured juvenile carp.

Cyprinids (Cyprinidae) with more than 93 confirmed species is the most diverse family among Iranian freshwater ichthyofauna having several complex groups such as Alurnoides bipunctatus. Alburnoides bipunctatus (Bloch, 1782) was the name applied to most populations of riffle minnows across Europe and the Middle East from France north of the Alps eastwards to the Black, Caspian and Aral Sea basins but ongoing research is revealing a greater diversity and presence of at least 6 species in Iran including Alburnoides qanati. This fish was described from a qanat in Kor river basin of Iran and was supposed to be restricted to this basin. However our extensive field works confirmed presence of A. qanati in the neighboring Sirjan River basin for the first time.
