    Cage culture of tilapia in some water resources (farm and agriculture ponds) of Bafq, Iran (2018)
    Iranian Fisheries Science Research Institute | Tehran, Iran
    Details
    Publication Date: 2021-05-19
    Description: Tilapia is the second cultured fish in the world. Up to 135 countries produces tilapia. Intensive culture systems of tilapia such as cage culture are recently developed because of limitations of water resources. In Iran, studies about tilapia were started in National Research Center of Saline Water Aquatics from November 2008 and some aspects of tilapia aquaculture and culture systems are surveyed. Investigation about cage culture of Nile tilapia, Oreochromis niloticus was performed in two culture periods of 2012 and 2014 in fresh and brackish water conditions of Iran for the first time. Stocking densities of fish in the cages were 25, 50, 75, 100, 125 and 150 fish/m^3 . 100g fish stocked reached 272-331 g during 80 days in the first study. However, 50g fish stocked reached 329-450 g during 145 days in the second study. Results of cage culture of tilapia in fresh and brackish water conditions showed ranges of FCR: 1.56-3.72 and 1.08-1.87, DGR: 1.63-2.91 and 2.14-2.92 g/day, SGR: 0.63-1.12 and 1.29-1.54, production: 5.98-38 and 7.17-41.6 kg/m^3 , respectively. Stocking densities 75-125 fish/ m^3 were appropriate especially in fish reared in brackish water cages.

    Broodstock Management, Reproduction, Cryopreservation in salmoind, Genetic Management and Selective Breeding in Responsible Aquaculture (2018)
    Iranian Fisheries Science Research Institute | Tehran, Iran
    Details
    Publication Date: 2021-05-19
    Description: This study was conducted to codify the guideline and indexes of broodstock management in salmonid fish and cryopreservation, selective breeding and sex reversal in hatchery to attain responsible aquaculture development. Cryopreservation includes of sperm and egg in term of economic is important in aquaculture. In this report mentioned the type and name of material. All female and sex reversal fish are produced by steroid hormone which mentioned in this report. Selective breeding include individual selection and family selection which could be used for genetic improvement of fish.

    An investigation on Vibrionaceae family of bacteria as Probiotic factors in shrimp culture (2018)
    Details
    Publication Date: 2021-05-19
    Description: We investigated the effects of Vibrionaceae family of bacteria as probiotics in the process of growth and survival rate of shrimp during propagation stages. Bacterial flora were extracted from seawater, culture farms, shrimp culture farms and sludge of private propagation farms. Different bacteria such as Vibrio alginolyticus (serotype 1-4), Vibrio splendidus I, Vibrio fluvialis II, Vibrio anguillarum I, Vibrio costicul, Vibrio vulnificus, Vibrio nereis, Vibrio campbelli, Vibrio natriegens, Vibrio proteolyticus, Vibrio pelagius II Vibrio fischeri, Aeromonas hydrophila, Aeromonas schuberti, Aeromonas salmonicida, Aeromonas veronii were isolated, identified and lyophilized. These bacteria were used in different experiments on shrimp life cycle stages while the shrimps were being fed on live food such as Chaetoceros, Skeletonema and Tetraselmis algae. Vibrio alginolyticus (serotype 1) with 107 cells/ml increased proliferation of Tetraselmis sp to 71 % in 6 days compared to the control experiment. Also Vibrio alginolyticus (serotype 4) with 105 cells/ml increased Tetraselmis sp. production to 389% in 6 days compared to control. Vibrio splendidus I was also found to be able to increase shrimp fork length in postlarvae stage 3 up to 23% as compared to control. Vibrio alginolyticus and Vibrio fischeri increased survival, fork length and body weight of green tiger shrimp in postlarvae stage significantly (P 〈0.05).

    Iranian Fisheries Science Research Institute | Tehran, Iran
    Details
    Publication Date: 2021-05-19
    Description: This study was conducted to codify the guideline and indexes of optimal management in warm-water fish farms to attain sustainable aquaculture which they are population density, species diversity, brood stock'smanagements, , capacity determination,growth and harvesting managements in cultural ponds. As results, these guideline and indexes were codifies for these fish farms and propagation centers.It's obviously that these sustainable patterns can be used for improving of permanent development for this aquacultural industry.

    Some biological aspect of the smallest Goby Fish (Knipowitschia caucasica Berg , 1916) in Gorgan Bay, Caspian Sea (2018)
    Details
    Publication Date: 2021-05-19
    Description: This research was conducted in Gorgan Bay in 1994. The results showed that spawning of Goby fish, in southern part of Caspian Sea in the area of Gorgan Bay, from early winter to early spring had been gradually. The biggest nun fish in length which caught was 46 mm. There was positive correlation between length and body weight in males and females and this ratio was higher in females than males. Fishes had positive algometric growth over all male to female ratio was 1-1.1. The range of relative fecundity was 290 to 550 eggs and in average 395.5 which was depended on the length of fish.
