    The study of adaptation, growth and survival of tilapia (Oreochromis.sp) in Bafgh brackish water (2018)

    Details
    Publication Date: 2021-05-19
    Description: An experiment was conducted to evaluate the possibility of adaptation, growth and survival of Red and Nile tilapia (Oreochromis niloticus) in underground brackish water. Fry with 0.3 and 0.7 g initial weight imported from Indonesia and after passing larviculture (20 g) were examined separately in fiber glass tank and earthen pond by two replicate. Fish were fed three times a day by using manual food (cp = 33.79) and carp food (cp = 25.05) at a restricted feeding program according to standard table during the 72 days rearing stage at light period. The results showed that some growth factors such as final weight, final length, daily growth rate, specific growth rate and weight gain in Nile tilapia were slightly higher than red tilapia but other factors such as survival and feed conversion rate in red tilapia were slightly higher than Nile tilapia. There were no significantly differences at 99% level among these factors. Length-weight relationship equation was w = 0.020 × TL3.012 in Nile tilapia and w = 0.015 × TL3.086 in red tilapia (r2 = 0.98), b value was 3.012 and 3.086 respectively in Nile and red tilapia representing isometric growth. So according to the results, good growth and high survival rate, it seems that both Nile and red tilapia could be good candidates for reproducing and rearing in brackish water condition.

    Raising economical efficiency of tilapia culture(Oreochromis sp.) by using the best stocking density in brackish water earthen pond (2018)
    Iranian Fisheries Science Research Institute | Tehran, Iran
    Details
    Publication Date: 2021-05-19
    Description: An experiment was conducted to evaluate the effect of stocking density on growth and survival of Nile tilapia (Oreochromis niloticus) in earthen pond. Fish with 13 g initial weight examined in three treatment 3, 6 and 9 fish/m2 in duplicates. Fish were fed on rainbow trout commercial food during the 105 days of culturing period at a restricted feeding program according to standard table during the light period. The results showed significant reduction in final weight, weight gain, daily growth rate, specific growth rate and survival by increasing stocking density while feed conversion rate increase by increasing stocking density( P 〈 0.05). The treatment 3 fish/m2 resulted the best growth rate (3.24 %/day) and survival (94.8 %), and the lowest feed conversion rate (0.51). So it seems that to achievement the highest profitability in earthen pond the 3 fish/m2 treatment is suitable.

    Adaptation, growth and survival of tilapia (Oreochromis niloticus) in Bafgh brackish water (2017)
    Details
    Publication Date: 2021-05-19
    Description: An experiment was conducted to evaluate the possibility of adaptation, growth and survival of Nile tilapia (Oreochromis niloticus) with 0.3g initial weight and red tilapia (Oreochromis sp.) with 0.7g initial weight in underground brackish water. Fry of Nile tilapia and red tilapia imported from Indonesia and after passing larviculture (25g) were examined separately in fiber glass tank by two replicate. Fish were fed at a restricted feeding program according to standard table during the light period. The results showed that some growth factors such as final weight, final length, daily growth rate, specific growth rate and weight gain in Nile tilapia were slightly higher than red tilapia but other factors such as survival and feed conversion rate in red tilapia were slightly higher than Nile tilapia. There were no significantly differences at 99% level among these factors. Length-weight relationship equation was w = 0.012×TL3.189 in Nile tilapia and w = 0.014×TL3.119 in red tilapia (r2 = 0.99), b value were 3.189 and 3.119 respectively in Nile and red tilapia representing isometric growth. According to the reliable growth and high survival rate (98%), it seems that both Nile and red tilapia could be good candidates for rearing in brackish water condition.

    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.
