The effect of automatic and manual feeding method on growth and survival indices of western white shrimp

60% of the cost of producing shrimp. Therefore, food type and feeding management are very important in shrimp growth and reduction of production costs. Feeding should be based on the nutritional needs of the shrimp. The number of feedings per day and the percentage of feeding depends on the breeding species, weight and amount of natural water production and climatic conditions of the region. In this study, shrimp growth and survival indices were compared in two methods manual and automatic feeder. The results of this study showed the specific growth indices, daily, final growth and survival of shrimp that were fed by automatic feeder method Showed a significant increase (P <0.05). The feed conversion ratio decreased (P <0.05). This study showed that automatic feeders are always available in the required amount of shrimp. Shrimp grow better and produce more economically than manual feeding.
