    Zanjani, Seyede Asal (Islamic Azad University, Science and Research Branch, Tehran, 2018)
    This study conducted to evaluate the toxic effects of a widely used oxadiazon herbicide,on common carp (Cyprinus carpio) fingerling (15 g). The 96-h LC_50 was determined, and the growth performance, serum biochemical and hematological parameters, DNA damage of erythrocytes cells, as well as histopathological changes were also determined in fish exposed to sublethal concentrations (1, 1.5 and 2 ppm) of the herbicide for 30 days. The 96-h LC_50 to C. carpio was found to be 3.9 ppm. Weight gain (WG), specific growth rate (SGR) and condition factor (CF) were decreased, while food conversion ratio (FCR) increased in the exposed fish groups (P< 0.05). Erythrocytes cells of fish exposed to 1, 1.5 and 2 ppm of oxadiazon showed DNA damage (21.3%, 22.9%, and 28.4%, respectively), significantly higher than control group (p < 0.05). Moreover, exposure to oxadiazon significantly decreased WBC, RBC, Hb, Hct as well as serum albumin, glucose, and total protein levels, while serum ALP was significantly increased in the exposed fish groups (

    Esmailzade, Nayersadat (Islamic Azad University, Science and Research Branch, Tehran, 2017)
    Ferrous Glycine Complex is a special form of chelated ferrous reported to be effective in anima improvement resulted from iron deficiency in adults, adolescents and children. To synthesize ferrous glycine complex, primarily glycine is solved in water and sodium hydroxide, then iron sulfate is added in it and the obtained solution shall be added to Ethanol to form ferrous glycine complex sediment. The resulted sediment is filtered and dried in drier. In the present study, iron cation is combined with glycine ligands and formed glycine-iron complex. Objective of the present research is to study changes in blood factors of 120 Cyprinus carpio were fed with average mass of 12 ± 1.16 gr. and average length of 7.17 ±0.29 cm for 14 days, and then influenced by sub-lethal dosage (4.5, 10, 12.5 mg/g) of edible glycine-iron complex in Cyprinus carpio food, and all were biometried after anesthesia, then they underwent depletion from their tail. The obtained results demonstrated that blood factors of H.C.T., Hb and R.B.C. in high dosage of complex in proportionate with blank and terms more than testing have had meaningful increase (P<0.05). White corpuscle, lymphocytes, monocytes and heterophile under influence of ferrous glycine complex had no significant difference statistically in proportionate with blank and terms more than test (p<0.05). M.C.V., M.C.H.C, M.C.H. and blood were completely different among testing and blank groups (P<0.05). Ferrous glycine complex were entered body of Cyprinus carpio and influenced on blood fish. Oxygen supply can improve tissues which led to increase of activity and hyperemia in fish and may act as a booster which affect immunity and defense system and cause reinforcement of this system, and resistance of Cyprinus carpio was increased against types of diseases.

    In this study, toxicity and probable effects of nanomaterial’s including titanium dioxide, copper oxide and zinc oxide in acute and chronic toxicity tests, separately and together has been studied on indicator species of water resources, including Daphnia magna, Amphibalanus amphitrit, Artemia fransiscan .Acute toxicity effects has been studid During the 96-hour and chronic toxicity test done in 14-day period (Artemia franciscana and Amphibalanus amphitrite) and 21 days (Daphnia magna), in exposure to Nano-materials separately, and the percentage of two nanomaterial’s and all three Nano-materials to study synergistic effects. Water quality parameters including DO, pH, EC, temperature, water hardness, SS and TDS in all treatments were measured, daily. The number and percentage of daily mortality recorded and by using Probite software LC50, LC10, LC90 were calculated. In chronic toxicity tests other parameters including larval development success, fertility, the percentage of adhesion to surfaces (barnacles) were recorded. Daphnia magna acute lethal toxicity LC50 96h for exposure to titanium dioxide, zinc oxide and copper oxide nanoparticles, were 123.796, 0.648 and 2.991 mg/ l respectively, and for barnacle were 25.434, 143.776 and 2.501 ml/l respectively, and for Artemia were 30.548, 173.209 and 4.328 mg/l, respectively. Statistical analysis and correlation coefficients in acute toxicity test showed a significant correlation between mortality and time. In Acute toxicity tests on Daphnia magna was found that titanium oxide and zinc oxide enhances the effects of mortality caused by copper. However, titanium dioxide and zinc has no effect on these at the same time not increasing. In the case of titanium dioxide and zinc oxide showed the synergistic effect on the toxicity of copper oxide, and copper oxide, titanium dioxide has a synergistic effect in toxicity. In Artemia titanium dioxide and zinc oxide, has the synergistic effect of copper oxide and copper oxide have the synergistic effect of titanium dioxide. In chronic toxicity studies in addition to mortality, the percentage of adhesion (Barnacles), success in the development of the larval stages, reproductive success, respond to light, were analyzed. These nanomaterials have an adverse effect on fertile time, delay and time spent in the larval stages of species, light respond and swimming in this species.

    In this study, the identification of the Acanthopagrus species Sparidae family by morphometric characters & meristic counts and the stock separation of Arabian yellowfin Seabream Acanthopagrus arabicus as the dominant species was determined through geometric morphometric and otolith shape in the west and east part of the Hormuz Strait. Samples were collected in five different areas including Khuzestan, Bushehr and Hormuzgan Waters as the west of Hormuz Strait, and Jask, Sirik and Sistan & Baluchistan Waters as the east of Hormuz Strait from June 2014 to May 2016. A. arabicus, A. berda and A.bifasciatus were identified in the northern part of the Persian Gulf & Oman Sea, the first one was identified as a dominant species of this genus. Evaluation of morphometric characters and meristic counts indicated that individuals of A. arabicus in west and east of Strait of Hormuz were significantly different from each other which showed high phenotype diversity of this species (p<0.05) and 85.3% of the individuals were categorized precisely in the correct classification which indicated as a key identification method in the region. From the meristic counts, the number of scales on the lateral line, on the chin and scales from the fifth and ninth spine of dorsal fin to the lateral line were the factors of separation in the west and east of the Strait of Hormuz. Body shape analysis was showed the most variations on the head and top of the body and significant differences of body shape was proved between west and east of Strait of Hormuz. Landmark positions in the samples of the west Strait of Hormuz were indicated the decrease of body depth, increase of head length, leaning of base and pectoral and ventral fin to upper part of the body, meanwhile it was contrary in the samples of the east. CVA correlation analysis showed a significant difference in body shape in the west and east of the Strait of Hormuz (P <0.0001). The otolith shape indices showed a significant difference in the west and east of the Strait of Hormuz and the results of the DFA analysis confirmed the accuracy of the classification of the species in the main region by 53.8 percent and the otolith shape in the west of the Hormuz Strait was more circular and had an equal growth in the length and width, while in the eastern part of the Strait of Hormuz they had more growth and aspect ratio, ellipticity and form factor of the area were approved. The results of the otolith Fourier Shape Analysis showed that six components out of the 77 main components were expressed 90 percent of the cumulative strength and difference, and the most changes were observed in the dorsal and ventral part of the otoliths of the Arabian yellowfin Seabream, and 70.4% of individuals of this species were correctly classified in the west and east of the Strait of Hormuz. The results of this survey confirmed two separate stocks in the west and east of Strait of Hormuz.

    Ketabi, Ramin; Jamili, Shahla (Kish International Campus, Tehran UniversityIran, 2017-06)
    Colletteichthys dussumieri or Batrachus dussumieri or Austrobatrachus dussumieri as flat toadfish is a sedentary and solitary species that lives partly buried in soft sand and mud or concealed in rock crevices, in coral reefs or in sea grass or weedy bottoms and in tidal pools, where they function as ambush predators feeding. They prefer high saline waters and also experts in camouflage therefore flat toadfish lives in the demersal, marine environment. Size of C. dussumieri is 14 cm in Iranian Waters of Persian Gulf (Kish Island). Their ability to change color to lighter or darker shades at will and their mottled pattern makes them difficult to see Toadfishes are said to be quiet vicious and will snap at almost anything upon the slightest provocation. Toadfishes do not school, but they are gregarious and tend to congregate together. They have limited dispersal ability because of their demersal eggs which lack pelagic larvae. Compared to other fishes, they are sluggish in nature. This species is dimorphism and spawning only once in a year. Toadfish are well known for their ability to "sing", males in particular using the swim bladder as a sound-production device used to attract mates. Food: Colletteichthys dussumieri is feeding fish, prow, crab, isopod, squilla and mullasca.

    Plectorhinchus gaterinus or Blackspotted rubberlip known as Grunts, Black-spotted Grunt, Blackspotted wweetlips, Spotted grunt, Spotted sweetlips. P. gaterinus is reef-associated and may also occur in sand banks and near estuaries. The Blackspotted rubberlip occurs in coral and rocky areas, inhabiting depths between 3 m and 55 m. It found singly or in large groups in coastal waters and reef flats often sheltering during the day under ledges. In some areas sweetlips are known as "Grunts" because they "grunt", the grunting sound is produced by their flat teeth plates rubbing together and this is amplified by their air bladders. Sweetlips can be distinguished from other species by their very large rubbery lips. P. gaterinus commonly reaches a length of 30 cm, with a maximum size of 50 cm in males. Body of the adults is silvery with black spots and yellow lips and fins. The forehead of the head is gray. This species is oviparous with distinct pairing during breeding. Small juveniles show longitudinal black stripes.

    Ketabi, Ramin; Jamili, Shahla (Kish International Campus, Tehran UniversityIran, 2017-05)
    Lutjanus ehrenbergii is known as Blackspot snapper and Black-spot snapper. L. ehrenbergii is widely distributed in the Indo-West Pacific at depths ranging from 5 to 20 m. This reef-associated species inhabits very shallow coastal habitats, often in large schools near freshwater run-offs. Adults inhabit coral reefs, while juveniles frequent inshore areas over sand, silt or coral rubble bottoms, occasionally in mangrove-lined streams and estuaries. This species may enter freshwater areas to consume small fish and invertebrates. This species reaches sexual maturity at approximately 2 years of age and reaches a maximum age of at least 11 years. Growth trajectories are significantly different between sexes for L. ehrenbergii with females achieving a larger asymptotic size than males. This species is a component of fisheries to varying degrees throughout its range. It is highly sought after in some areas, such as the Persian Gulf, and is commonly seen in subsistence fisheries and markets through other parts of its range.

    Culcita novaeguineae or cushion star is a species of starfish. It has short arms and an inflated appearance and resembles a pentagonal pincushion. It is variable in colour and can be found in tropical warm waters in the Indo-Pacific. C. novaeguineae is living coral reefs at reef edge and slope at depths of 1 to 20 m. We report for the first time from Bali Waters (Indonesia). This species has exhibited a slight preference for the coral Acropora spp. over Poccilopora spp. and Porities spp. A mature C. novaeguineae is pentagonal in shape with an inflated appearance and much-abbreviated arms. It can grow to a diameter of 30 cm. Rows of tube feet are on the underside, and it has a central mouth. The color is very variable and includes a mottling with darker and lighter shades of fawn, brown, orange, yellow and green. The armored body wall is made of calcareous ossicles which are supported internally by pillars which buttress the ambulacra. The armouring contains pits into which the tube feet can be retracted. The body cavity is filled with water. Small cushion stars are very different in appearance. They are star-shaped, with five short, broad arms and a low profile. As they grow, the inter-arm areas fill in and expand relative to the tube-feet areas, and the arms get shorter relative to the disc which becomes inflated and more massive.

    Ketabi, Ramin; Jamili, Shahla (Kish International Campus, Tehran UniversityIran, 2017-06)
    Ostracion cyanurus is known as bluetail trunkfish, bluetail boxfish, Arabian Boxfish and Arabian Trunkfish. The family that this fish belongs to is called the boxfish family. Origin of this fish is Western Indian Ocean and Persian Gulf. O. cyanurus Inhabits areas of moderate coral growth, it’s Solitary and found close to shelter. O. cyanurus has a unique square shape and a particular way of swimming. They have a rather special personality, which one quickly comes to love. We report from Iranian Waters (Persian Gulf, Kish Island). Maximum length is 15 cm in Kish Island. They found at depths of from 2 to 8 m (in Kish Island, Iran). They live typically off a mixture of algae, coral polyps, zooplankton, and in some cases crustaceans. They are not normally reef safe and when small will require gentle water circulation. This species has a toxin in its skin, which it releases when highly stressed or dying. This poison can kill all the aquatic life in the aquarium, if unlucky. Bluetail trunkfish can grow up to 15 cm.

    Ketabi, Ramin; Jamili, Shahla (Kish International Campus, Tehran University, 2017-04)
    Chromis viridis (green chromis) is a species of damselfish. It is found in tropical and subtropical waters. C. viridis is encountered in wild specimens prefer to school in large shoals amongst branching corals like Acropora in sheltered areas such as subtidal reef flats and lagoons. We report for the first time from Iranian Waters) Persian Gulf, Kish Island), we found it at depth of 2-8 m, and Maximum length is 7 cm in Kish Island (Iranian Waters). Adults of this species can grow up to 10 cm at maximum length. When they are breeding, males turn more yellowish. The marriages are a pair matter, but they take place grouped. The males chose for the nest, a small dimple dug in the sand, the dead branch of madrepora or simply, one hospitable seaweed. Then they dance, moving up and down, like if they were jumping inside a virtual column of water, for attracting the attention of the females and show the competitors that is their place. Oviparous, distinct pairing during breeding. Eggs are demersal and adhere to the substrate. Males guard and aerate the eggs. Juveniles closely tied to individual coral heads.

    Ketabi, Ramin; Jamili, Shahla (Kish International Campus, Tehran University, 2017-04)
    Tetrosomus gibbosus, commonly called humpback turretfish, helmet cowfish, camel cowfish and thornbacked boxfish, is a species of boxfish native to the Indo-West Pacific. T. gibbosus is mainly found at depths of 37–110 m on slopes or over muddy bottoms, but can sometimes be seen near hallow seagrass beds also off the coral reef and in the contiguous submarine prairies, on the sandy and detrital. We report for the first time from Iranian Waters ) Persian Gulf, Kish Island), we found it at depth of 3m, and Maximum length is 30 cm in Kish Island (Iranian Waters). It reaches up to 30 cm in length, but is more common at around 20 cm. Like other boxfish, its flesh is poisonous and defending with the spines and poison. T. gibbosus is not a very good swimmer. The coloration varies from the sandy yellow to the blue, in the adult individuals. As for the Ostracion the skin emits defensive poisonous mucus, and in the small pools these toxins may aver fatal for the other fishes if it is repeatedly disturbed or if it passes away. T. gibbosus is a hermaphrodite protogynous species: which means that at the beginning all the animals are females and then, while growing, may transform into males. The humpback turretfish nourishes of sea-weeds, sponges, molluscs, worms and crustaceans it ferrets out on the bottom. The juveniles live in small schools, but the adults, apart the reproductive period, are usually solitary.
  • Chaetodon nigropunctatus (Sauvage, 1880)

    Ketabi, Ramin; Jamili, Shahla (Kish International Campus, Tehran University, 2017-03)
    Chaetodon nigropunctatus or Black-spotted Butterflyfish inhabits shallow coral reefs and sandy lagoons rich in stony coral growth at depths between 3 - 15 m and feeds mainly on stony coral polyps. We report for the first time from Persian Gulf (Kish Island, Iran). Maximum length is 15 cm in Persian Gulf (Kish Island, Iran). C. nigropunctatus is indicator species for specific coral-feeding. The butterfly fish are found to be living both in groups and as an individual. They are found swimming in groups and sometimes they swim alone until they get a partner. C. nigropunctatus is oviparous breeders and monogamous, they form pairs during breeding. Spawning usually occurs at dusk. Females are often visibly distended with eggs when they are ready to spawn. The male swims behind and below the female, and here he uses his snout to nudge her abdomen. A common element among species seems to be an ascent into the water column to release gametes (eggs and sperm). After a few “false starts” the pair rises up into the water, the male’s snout against the female’s abdomen. They release a white cloud of gametes and rush back toward the bottom.
