In a feeding trial for 75-day, gammarus extracts were added to juvenile Acipenser percicus diets at different levels in order to evaluate its effects on growth and survival rate. In this study, three different dietary levels of extracts (1:25, 1:50 and 1:175) were added to feeding amount of juvenile A. persicus with three repetition. This experiment was carried out in 500 liters PVC tanks which were filled with about 200 liters of water. Thirty of Beluga juveniles with average weight of 5.98±0.2g) were stocked in tanks and then fed up four times a day. Growth and survival factors were analyzed at the end of experiment time. The results showed that the addition of extracts in diets led to more improvement of growth factor and increasing of FCR. Although, treatments compare to control had significant differences but the best values of improvement of growth index was achieved in gammarus extracts with average level of 1:50. There was no significant difference in survival rate between treatments (P> 0.05).

The wild goat (Capra aegagrus), belong to Artiodactyla order and Bovidae family, that is listed as vulnerable (A2cde) by IUCN Red list, and dispersal in the most mountainous areas which has adequate security. Unfortunately, during recent years, there was a decrease drastically in its population in the most habitats due to the illegal hunting. In this study, the factors that may affect the distribution of this species have been studied during 2010 to 2011 in the Lashgardar protected area. Different environmental variables such as topography, climate, vegetation cover, and geology along with the presence/absence data in 61 locations were recorded. The analysis was conducted using binary logistic regression. Results showed that slope, altitude, vegetation cover and average annual temperature were the most distressing environmental factors defining the presence of the species in this area. In this regard, the slope had the greatest impact among all other variables due to its relation to other parameters.

In this investigation rainbow trout growth rate, blood factors, food valuables were studied in fresh and brackish water. For this reason, some 180 young rainbow trout with weight of 47.10 0.1g were released in 6 polyethylen basins with capacity of 1.5m3 water. Two treatments with three repetitions were done. At the time of testing, feeding for each repetition was done with trend to water degree and fish biomass. The biometery from each fish was done and recorded every 15-day. After 126 days, the live fishes were transferred to libratory and after biometry, their weight and length; all blood desired factors were measured with taking blood from their hearth. Also chemical analyzed of their muscle was done. The results showed that fish growth in brackish water from after third biometry process showed significant increase. With due attention to other treatment amount of WBC, Hb, HCT, MCV, MCH, MCHC, Lymp Throm and K+ in brackish water showed significant increase compared to fresh water (P<0.05). Also chemical analyze test showed that the amount of fat, dry material in brackish water fishes had a significant difference (P<0.05). Wet amount of fish’s muscle in brackish water was higher compare to freshwater and had significant differences (P<0.05).

The experiment was done during 24 hours in laboratory conditions. Fifteen fishes with mean weight of 524g and total length of 213cm exposed to lethal concentration of total ammonia (N-NH4) under stable conditions. For zeolite enrichment, zeolites frequently were exposed to solution of 10% NaCl and temperature of 90ºC for 30 minute. In lethal concentration of ammonia (25mg/l), amount of 1, 3, 5, 7, 8g/l enriched–zeolite was used. The results showed, there was significant difference between treatments (P<0.05). Using 8g/l enriched–zeolite could prevent mortality of fishes. Behavioral symptoms were investigated during tests. Samples were taken from gill of fishes and histopathological sections were prepared. The major lesions in the gills were hemorrhage, hyperplasia, edema and epithelial cells necrosis.

For identify and study of coral reefs in Chabahar Bay, field study started after four coral stations were chosen in 2008 and was conducted in three stages by the end of the year. For investigating the status of coral cover; eight main factors were considered. LIT method elected in two depths of 2-3m, and 5-8m. Finally, 20 hard coral species of 14 geneses and 9 families and one soft coral species were identified. The most species were belonged to Faviidae families. Favia favus, F. mattahi, Platygyra daedalea and Siderastrea savignyana observed in all stations. Station (4) had lowest species. The highest percentage of live coral cover in 2-3m depth with 35% was observed in station 3 and the highest dead coral was seen in station 1. In 5-8m depth, stations 1 & 2 had the highest live corals and highest dead corals were observed in station 2. The DI and CI indexes in 2-3m depth the highest stress (- 0.28) was observed in station4 and development and growth status was very weak (- 0.75). Station 3 in term of DI and CI indexes had a good status. In 5-8m depth, station 4 has no corals ecosystem and also on index results this habitat is not suitable for corals development and growth. In this depth, stations 1 and 2 had good condition and stress rate.

Diazinon is an organophosphate pesticide that is widely used in agriculture and household for controlinf of soil insects, plants, fruits and vegetables. Toxics may create cytopathology and behavioral changes in fishes and other aquatic organisms. A further study on the effects of the pesticide diazinon has been focused more on physiological and biochemical changes and very rare on hematologic fluctuations. For this reason, 120 kutum with average weight of (11±1g) were selected in 4 treatments with 3 replicates. The LC50 concentration of the toxin was determined in previous experiments (25, 50 and 75%) of the lethal concentration of diazinon 60% were considered for this experiment. For adding the toxic, a standard solution with 6cc, 12cc and 18cc concentration used with 25, 50 and 75% of LC50 was calculated and with a pipet added to 100lit tub with fish. Stress factors, cortisol and glucose were statistically (P<0.05) increased in higher levels of diazonon. There was no significant difference in terms of lactate Dehydrogenase between experimental groups and control (P>0.05). Level of cholinesterase in experimental groups were significantly lower than the control (P <0.05).

The Syrphidae family, Diptera order with 6000 species, commonly named Hoverfly in USA and Flowerfly in Europe. The larvae of many species of Syrphidae are predators of aphids and play an important role in biological control. The Syrphidae included three subfamily, Eristalinae, Microdontinae and Syrphinae. Sub-family Milesiinae have 12 tribes and sub-family Syrphinae have 3 tribes which named Bacchini, Paragini and Syrphini. Genus Metasyrphus belong to tribe Syrphini and have two sub-genera, Lapposyrphus and Metasyrphus. Genus Merodon and Eumerus belong to tribe Merodontini. Genus Merodon is identify hairy bomble bee mimic with a great range of colourful forms. Genus Eumerus is very distinctive in having the combination of a flat hairy face and have small but robust species. Genus Chrysogaster belong to tribe Chrysogasterini. The investigation was carried out during May 2009 to August 2010 in eastern part of Tehran Province. Initially 12 stations in Damavand and Firoozkooh were chosen according to the vegetation and topographic maps were included: Damavand, Abesard, Rine, Gilavand, Sarbandan&Derakhtebid(Mazrae), Cheshme, Poloor, Firoozkooh, Shahrabad, Kaboodband, Dashtemorgh and Abeask &Haraz river. Species mentioned in this report were collected from four stations, Cheshmeh, Sarbandan & Derakhtebid (Mazrae), Dashtemorgh and Abesard. Then collecting was done by sweeping net in 6 mounths, subsequently specimens were killed, and taken to the systematic laboratory of Shahid Beheshti University, and identified by using keys such as Stubs & Falk,1996 , Bi-Bienko,1988 and Speigh & Sarthou, 2008. Four species namely Metasyrphus latilunulatus Collin,1931; Chrysogaster hirtella Loew,1843; Merodon elegans Hurkmans, 1993 and Eumerus ornatus Meigen, 1822 were identified. These four species are newly reported from Iran.
