Vannamei Shrimp Culture Harvesting Techniques Process. The vannamei shrimp. Vannamei is fed 4-5 times daily at 16% of the body weight initially and gradually reduced to 2% with a sinking pelleted feed having 25-40% protein, 6-8% lipid, 2% unsaturated fatty acids and 0.25-0.4% cholesterol. Other aspects of feeding are similar to that of the tiger shrimp.
Care and monitoring
The quality of pond water is monitored and maintained as in the case of the tiger shrimp. Aerators @ 1 hp per 500 kg of biomass are positioned in such a way that the sludge is accumulated at the centre of the pond bottom. It is removed during culture using bottom central drainage or sludge pump, which is essential for high density culture. In order to aid the process, sludge settled at other places should be disturbed regularly. This is achieved through dragging of chains at the bottom at regular intervals from all the sides of the pond. Weekly growth rate will be 1.5 g. Other aspects are same as that of the tiger shrimp.
The vannamei shrimp attain 20-25 g size within 90-120 days depending on the stocking density. As it lives in water column, majority of the stock is harvested by cast netting and drag netting which reduces overcrowding and stress. Production of 6-10 t/ha can be obtained with a survival rate of 80%. The FCR will be normally 1:1.25

In all cases, final harvest is by hand after all the water has been drained from the pond.
