    Study on Macrobenthic communities in the range of fish cage-culture area (before breeding) in the southern Caspian Sea (Mazandaran coast-Kelarabad) (2018)
    Iranian Fisheries Science Research Institute | Tehran, Iran
    Details
    Publication Date: 2021-05-19
    Description: The abundance and biomass of benthic macroinvertebrates were studied in the place of fish cage culture in southern coasts of Caspian sea (Mazandaran waters- kelarabad). The goal of this study was to consider of fish cage culture effects on the abundance and biomass of benthic macroinvertebrates. The sampling was carried out in 3 stations in depth of 20 meter of Kelarabad waters monthly. In this study 7 species were identified belonged to 5 genus of 4 family. Totally 23442 sample of benthic invertebrates were counted that the lowest and highest abundance were in station 1(23.4%) and station 2(46.8%) respectively. The results of stations study showed that the highest abundance and biomass were in stations 2 and 3 with the average of 646 ± 1230.4 n/m2 and 0.526 ± 1.001 gr/m2 respectively. This coulld be respectively dependant to not settling of cage (witness station) and appearance of Cerastoderma glaucum because of its large body in station 1. The difference of abundance and biomass between different stations was not significant (p ›0.05). The study on abundance and biomass in different seasons showed that the highest abundance in autumn with the avarage of 888.13 ± 1371.58 n/m2 belonged to Strblospio gynobranchiata and the highest biomass belonged to C. glaucum which was because of appearance of not native species of polychaeta and also the species with shell covering from bivalvia. The results showed that the specie of S. gynobranchiata from polychaeta including 93.3% of abundance was the dominant specie that could be related to appropriate ecological conditions for living and high adaptability.It was concluded that the abundance and biomass of benthic macroinvertebrates in station 1 was lower than other stations which was related to fish cage culture activity and its effects on benthic macroinvertebrates. So it is suggested that each mariculture activity in southern coasts of Caspian sea should be carried out with regarding to environmental considerations and performance of comparative evaluation project of environmental effects.

    Evaluate The Impact of Dietary Herbal Appetizer on the Growth Performance of Growth out shrimps (Liptopenaeus vannamei) (2018)
    Iranian Fisheries Science Research Institute | Tehran, Iran
    Details
    Publication Date: 2021-05-19
    Description: The main goal of the current study is to evaluate the impact of dietary herbal appetizer on the growth performance of growth out shrimp. This project was conducted at Caspian sea research institute of ecology from 2014 to 2016. Totally 180shrimps with an average weight of 2 g were randomly distributed to 9 fiberglass tanks with area and depth of 1m2 and of 0.6 m. The experiment lasted for eight weeks and the shrimp were fed by three different diets as follows: 1. Commercial pellet contained no herbal additive (control diet) 2. Commercial pellet contained 1% herbal appetizer and 3. Commercial pellet contained 2% herbal appetizer. The results showed that prawn weight gains for diet 1 , 2 and 3 were 6.28, 5.68 and 6.07 respectively. The estimated growth rate was 2.34g for control diet, 2.22g for 1% inclusion of the additive and 2.28g for 2% inclusion of the additive. Results also showed that inclusion of the additive did not change statistically average final weight (p〉0.05). A larger weight gain was observed at 0% additive inclusion although this was not statistically different with other treatments. In conclusion, with regard to the observed results, herbal appetizer administration cannot improve growth, feed conversion rate and weight gain in common carps.

    A comparative survey of abundance and biomass of Caspian Sea macrobenthos in coastal waters of Mazandaran Province (2018)
    Details
    Publication Date: 2021-05-19
    Description: Caspian Sea macrobenthos was surveyed every two months from December 2007 to October 2008, in the west, east and central parts of Mazandaran province waters. Each area was sampled with 3 replicates at 2 depths of 5 and 10m by Van Veen grab. Five different classes were recognized, including Polychaeta (52.7%), Oligochaeta (27.8%), Bivalvia (12%), Cnistacea (7.5%) and Insects (0.07%). Total mean (LSD) abundance and biomass were 2727± 1303 individual/m2 and 88.9±22.93, respectively. The Polychaeta demonstrated the highest abundance and Bivalvia had the highest biomass. The highest abundance of macrobenthos was found in eastern and the highest biomass in western coasts of Mazandaran. In August 2008, macrobenthos abundance showed higher values. In October, remarkable difference was observed between the abundance of Polychaeta and other macrobenthos organisms. According to Kniskal-Wallis test, abundance and biomass of the entire macrobenthos classes except Insects, showed a significant difference between sampling months (P〈0.05). Macrobenthos biomass had no significant difference among the three areas whereas abundance demonstrated a significant difference within these areas (P〈 0.05).

    Details
    Publication Date: 2021-05-19
    Description: The main goal of the current study is to evaluate the impact of dietary herbal appetizer on the growth performance of growth out common carp. This project was conducted at Caspian sea research institute of ecology from 2013 to 2014. Totally 186 common carps with an average weight of 126.3 g were randomly distributed to 9 fiberglass tanks with area and depth of 16m2 and of 0.6 m. The experiment lasted for eight weeks and the fish were fed by three different diets as follows: 1. Commercial pellet contained no herbal additive (control diet) 2. Commercial pellet contained 1% herbal appetizer and 3. Commercial pellet contained 2% herbal appetizer. The results showed that common carp weight gains for diet 1 , 2 and 3 were 51.6, 49.3 and 57.6g respectively. The estimated growth rate was 39.03g for control diet, 40.03g for 1% inclusion of the additive and 48.65g for 2% inclusion of the additive. Results also showed that inclusion of the additive did not change statistically average final weight (p〉0.05). A larger weight gain was observed at 2% additive inclusion although this was not statistically different with other treatments. In conclusion, with regard to the observed results, herbal appetizer administration cannot improve growth, feed conversion rate and weight gain in common carps.
