Abstract

The collection of seeds from the wild is the main source to obtain the stocking material for the cage. This can be carried out when the seed production cost is very high or where the availability of seed from nature is in large quantity. It is important to know the biology of the fish species either to duplicate reproductive condition on the farm or to know when and where to collect the fish. The artificially produced seeds in the hatchery are used widely in cage culture practice all over the world to avoid depletion of stock in the wild. The transportation of the seeds to the culture site plays an important role as maximum mortality occurs during this process because of change in metabolic pattern of the fish due to stress. The appropriate quantity of seeds should be stocked in each cage for obtaining good production. This chapter mainly deals with all these aspects in detail
