    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.

    Comparative efficiency of two nursing systems 1 in sex reversed tilapia (black tilapia, Oreochromis niloticus and red hybrid tilapia, Oreochromis sp.) (2018)

    Publication Date: 2021-05-19
    Description: The production of tilapia fries is a basic requirement for the tilapia culture industry and it is necessary to optimize the production of fries to increase the profitability of the hatcheries. In the present study, the production fries of Nile tilapia, Oreochromis niloticus and hybrid red Oreochromis sp. using tank and hapa systems was investigated. The results showed higher significant difference in the length and weight of fish in the hapa-free tanks, by t-test (p 〈0.05) but much isometric fries and more survival in the hapa system. SRT were similarly 100% in both systems. Also, the means of total length, body weight and survival of hybrid red Tilapia were significantly higher than Nile tilapia fries, by t-test (p 〈0.05). Producing SRT fries in tank system with hapa tended to more isometric fries and appropriate survival, however fries produced in tanks without hapa had higher total length and body weight.

    Optimization of breeding (salinity, light regime, brood density and sex ratio) of cultured tilapia under brackish water of Bafgh, Iran (2018)
    Iranian Fisheries Science Research Institute | Tehran, Iran
    Details
    Publication Date: 2021-05-19
    Description: Tilapia is one of the most important cultured fish in the world. World production of tilapia is highly increased in recent decades. Tilapias can live in different aquatic ecosystems due to their reproductive strategies. On the other hand, the gap between seed supplies and farmers' demand is one of the most serious limitations for tilapia culturists. Notice about different effective agents on tilapia reproduction aspects might be useful for increasing of production and better management of tilapia hatcheries. Studies about tilapia were started in Iran from November 2008 for the first time. Some reproductive normative of cultured tilapia in brackishwater were defined. In the present study, sex ratio, stocking density, photoperiod, water salinty and replacement period of female brooders of the Nile tilapia, Oreochromis niloticus were investigated. Studied reproduction indices showed sex ratio 1:1 (F:M), stocking density 5/m3, photoperiod 12:12 (L:D), 8ppm water salinity and 10 days replacement of brooders were suitable.

    Pathogen monitoring in indoor systems of tilapia aquaculture in Bafq, Iran (2018)
    Iranian Fisheries Science Research Institute | Tehran, Iran
    Details
    Publication Date: 2021-05-19
    Description: In recent years, aquatic diseases have damaged aquaculture industry in different areas of the world. Although tilapias are known as resistant fish against different pathogens, but there are some reports about infectious diseases of tilapia. Tilapia aquaculture in Iran is in the beginning stage. So, planning for hygiene observations and preventing of disease prevalence must be considered. Tilapia hatchery and indoor systems of National Research Center of Saline water Aquatics were monitored for infectious disease from October 2012 to February 2014. Unusual locomotion/feeding or uncommon signs in the shape or body surface of cultured tilapias, fries and eggs or exceed mortalities were mentioned for bacterial, fungal, parasitic or viral pathogens. Infectious agents in this study were bacteria Streptococcus and Edwardsiella, the fungi Penicillium and Aspergillus and parasitic monogeneans Gyrodactylus and Dactylogyrus. No viral agent was diagnosed. Although recorded pathogens were rarely observed during the study but much attention must be paid for hygiene monitoring and instruction performance.
