    Short communication: Determination of total mercury in common carp, Cyprinus carpio, large scaled barb, Barbus grypus, tiger tooth croaker, Otolithes ruber and from surface waters in Khuzestan, Iran (2018)

    Description: Fishes are a valuable source of dietary protein and minerals for seafood consumers and are also used in pharmaceutical products (Mozaffarian, 2009). Over the past several decades aquatic ecosystems have been extensively contaminated with pollutants released from domestic and industrial waste waters and other anthropogenic activities in Khuzestan, Iran. Heavy metals such as mercury are considered as one of the four most important pollutants of aquatic life because of their high toxicity and ability to bioaccumulate in tissue of aquatic organisms (Hajeb et al., 2009). The toxicity of Hg is highly dependent on its chemical form. Organic mercury compounds are more toxic than inorganic mercury salts which may bioaccumulate to levels that could increase health risks to seafood consumers (Syversen and Kaur, 2012). Since most mercury in fish tissue is present as methyl mercury (Me-Hg), it has been recommended that T-Hg in tissues can serve as a surrogate for MeHg (Kannan et al., 1998).

    Effects of water temperature and migration time on some fecundity indices and fertilization rate of female Kutum, Rutilus frisii kutum, migratory to Shiroud River in the southwest Caspian Sea (2017)
    Details
    Publication Date: 2021-05-19
    Description: Kutum, Rutilus frisii kutum, is an commercially important fish in the Caspian Sea. The fish enters the rivers leading to the Caspian Sea for spawning. One of these rivers is Shiroud River. In the artificial propagation process of Kutum, different factors are involved in quality and quantity of female broods eggs and also in the best temperature and migration time for spawning. The influence of temperature and migration time on some fecundity indices and fertilization rate of female kutum in Shiroud River was studied in the spawning season. In this study, 90 individual females were studied from February to May 2007. Averages of total length, weight and age were 43.26 cm, 832.08 g, and 4.41 respectively. Results showed that maximum egg diameter (1.86 mm), number of eggs per each gram of body weight (309.12), relative fecundity (56.21) and fertilization rate (95.82 %) were obtained from 5 to 20 April (15.95°C). Maximum ovary weight (201.00 g) and absolute fecundity of eggs (49987.18) were obtained from 6 to 20 March (17.74°C). Relationship between temperature and migration time and fecundity indices was linear and weak.
