    Description: The swim bladder status of false trevally (Lactarius Lactarius) was studied from November 2007 to October 2008 in coastal waters of the Oman Sea. A number of 702 swim bladders of false trevally specimens were collected randomly from catch composition of gillnets and bottom trawler. False trevally has an unusual swim bladder, as the first and the second spines of its anal fin are joined that creates a single bone, which is called anchorage bone, and passes from the middle of the swim bladder and 2 lobes of the gonad and connects to the 10th vertebra of the spinal column. Another ending of this bone is wide and reaches anal fin base. This bone is like an anchorage for swim bladder of false trevally and it functions as a center of gravity of the fish in anal fin base. It firms the exterior part of the fish body, so the fish swims through rough waters easily.

    Description: In order to isolate bacterial strains resistant to iron and nickel, deposit samples were collected from five stations in Musa Bay and cultured on BHI agar medium containing 1000 ppm of iron and 50 ppm of nickel. Endurance threshold of strains isolated to different concentrations of iron (1000- 15000 ppm) and nickel (100- 25000 ppm) in BHI broth medium were evaluated, the most resistant strains were selected and MIC and MBC were determined. Results of the current study demonstrated that among 16 and 12 resistant strains to nickel and iron, two selected strains (Bacillus subtilis and Micrococcus sp. ) as the most resistant strains had MIC and MBC (29700 and 29800 ppm) and (26300 and 26500 ppm ), respectively, Iron’s MIC was not assessed. Results of atomic absorption analysis demonstrated that the highest amount of nickel reduction in a medium with concentration of 194 ppm and 71 ppm were 16.7% and 63% after 72 hours by selected strain of Bacillus subtilis respectively, and in a medium containing 158 ppm iron, after 50 hours 8.4% by selected strain 7, while dead biomass of strain 16 reduced nickel to the amount of 40.6% and it reduced 21% and 4% of iron in solutions with 46 ppm and 792 ppm of iron. Results of molecular analysis demonstrated that strain 16 was Bacillus subtilis. In addition, Bacillus subtilis being isolated in this study with ability of nickel and iron removal is an appropriate candidate to be used in aquatic environments.

    Description: Otolith shape analysis is one way to identify stocks of different fish species in the marine environment. Length, width, area, perimeter, form factor, aspect ratio, roundness, circularity, ellipticity and rectangularity analyses of otoliths were undertaken to assess patterns of spatial and temporal stock structure of a wide-ranging fish, the Arabian yellow fin sea bream Acanthopagrus arabicus. Fish were sampled from 125 stations across the distribution range of the species in the Northern Persian Gulf and Oman Sea from June 2014 to May 2016. Analysis of morphometric parameters of otolith showed the minimum size in Khuzestan waters and the West Strait of Hormuz and the maximum size in the East Strait of Hormuz. In Bushehr waters, form factor showed the lowest and circular factor showed the highest frequency. These findings are in agreement with the irregularity in otolith margin of this area. The highest aspect ratio of otolith indicated higher growth in Khuzestan Waters. The thinner and longer otoliths were identified in the East Strait of Hormuz region. Further, rectangularity ratio factor in the Bushehr and West Strait of Hormuz waters was higher in comparison with other regions and this finding confirmed the quadrilateral otolith shape of this region. There are significant differences among otolith morphometric variables of the A. arabicus (p〈0.05). The result of discriminant analysis on morphometric parameters indicated that 53/8 percent were in their geographic location accurately.

    Description: A survey on Biodiversity of Cyprinidae family in Iran Cyprinidae family is the biggest and most important fish families with 367 Genera and 3006 species in the world. Members of this family is the most important freshwater species are present in a variety of freshwater ecosystems. Some of them can also live in brackish waters. Iran has about 93 species in the family Cyprinidae and consist half of the fishes in inland waters. In the past two decades many changes occurred in aquatic ecosystems, Fish habitat conditions changed and a lot of them are affected and some species are endangered or put under pressure. Restricted fish migration, Some Exotic species and have been entered in water resources and have narrowed arena on continued existence of native species. On the other hand, climate change and drought on water resources aggravate existing conditions. It is necessary effects of these changes in the family Cyprinidae be reviewed and analyzed.

    Description: In order to determine the reproduction period, the peak time of spawning, length of maturity and mesh standard size for False Trevally (Lactarius lactarius), we conducted a study from November 2007 to October 2008 in coastal waters of the Oman Sea. A total of 702 False Trevally specimens were collected randomly from the catch composition of gillnets and Ferdows-3 stem trawler. Mean total length and total weight were estimated at 22.7 plus or minus 2.13cm and 142.2 plus or minus 41.64g for females and 20.4c 1.89cm and 103.14c 29.07g for males respectively. Male to female sex ratio was 0.37:1 and females were more abundant than males in all months except June and August. Males had smaller sizes than females and the females outnumbered the mails up to the total length 25.5cm. The maximum of GS delta was estimated at 3.69 for females in June and 0.89 for males in July. The trend of GS delta and the frequency of maturity stages showed that reproduction period was from February to September with a spawning peak in August. Absolute fecundity was calculated at 102032 ova and relative fecundity was estimated at 4491.9 ova and 780.7 ova to total length and total weight respectively. Lm sub(50%) (length of maturity) and standard mesh size was calculated at 24.4cm and 3.9cm, respectively.

    Description: The two species, Luciobarbus barbulus (Heckel, 1847) and Luciobarbus pectoralis (Heckel, 1843) are similar to each other and some researchers get confused and mistake one for the other. During a one year seasonal sampling, 79 specimens were collected from the main rivers of west and southwest of Iran in the Tigris River basin using electrofishing as the main method for sampling. Samples were fixed in 10% formalin and transferred to the laboratory, Then 24 morphometric and meristic parameters as well as 11 ratios of the major parameters between the two species were studied. According to the results of this study in addition to similarities there are ten differences between them, with the most important ones being the shape of the head and lips, number of gill rakers and number of pectoral fin branched rays.
