    Feasibility on cage culture of the orange-spotted grouper (Epinephelus coioides ) (2018)
    Iranian Fisheries Science Research Institute | Tehran, Iran
    Details
    Publication Date: 2021-05-19
    Description: The present study was carried out to evaluate the possibility of rearing the orange-spotted grouper (E. coioides) juvenile to marketable size in buoyant cages in Khuzestan province coast waters. Juvenile fishes for the study prepared from Bandar-e-Imam Marine Fish Station and reared them in 5-ton fiber glass tank for one year period using common pellet feed and trash fish to reach 50 g mean weight. Young fishes were stocked in 6 rectangular cages (3×3×3 m) to assess their growth performance with two test feeds i.e. pellet feed and trash fish (3 cages for each treatment) with the density of 30 fish /m3 (810 fish/cage) for 143 days rearing period (started on July). Better growth with significant difference (p〈0.05) were observed for fishes fed trash fish (523.71±27.95 g) than those fed pellet feed (317.53±22.10 g). Although lower survival rate was recorded for fishes fed trash fish but difference with the pellet feed was not significant (p〉0.05). Results also showed that the FCR for the trash fish was acceptable, and hence it is recommended to consider the trash fish price and its labour cost befor using it as the main diet in cage culture activity.

    Possibility of intensive whiteleg shrimp (Litopenaeusvannamei) culture in outdoor pond in Choeibdeh Abadan (2018)
    Iranian Fisheries Science Research Institute | Tehran, Iran
    Details
    Publication Date: 2021-05-19
    Description: This investigation has been carried out to complement the previous related study, aiming the Possibility of culturing white leg shrimp (L.vannamei) at higher densities of 50, 70 and 90 indiviuals/m2. After 122 days rearing period, the highest mean weight of shrimp obtained at density of 50 indiviuals/m2 (16.91± 2.43 g) with no significant difference with that obtained at 90 indiviuals/m2 density (P≤ 0.05). Mean weight gain of the shrimp in the 70 indiviuals/m2 density (14.35 ± 2.17g) was significantly lower than that at other densities (P≤0.05). Results showed no significant (P〉 0.05) difference between survival rates , FCR and PER in the different treatments. The highest yield of 14008 kg/ha with the mean weight of 19.43 g/shrimp was obtained at the density of 90 indiviuals /m2. According to the results of the present study it could be concluded that 90 indiviuals /m2 could be adapted as suitable density for economically feasible culture of L.vannamei in earthen ponds in Chowibdeh site if the appropriate conditions are provided.
