Global seafood consumption has significantly increased in the last couple of years, India is playing a major role in the production and supply of the world consumption and aims at increase its supply to $10billion USD by 2022. Odisha, having a large coastal area plays a major role to it and specifically Balasore district. The production in odisha has risen over 300% in last three years to 75000 mt, however the production capacity is only is of 60000 mt. Considering the current demand and supply gap, and seeing a viable business opportunity, Mr. Pratik Jena, an young entrepreneur , aged only about 19 years founded “Highland” group of entity comprising of
A dealer of Avanti feeds ltd, a premier feed supply company in India, highland marine aims just to double its sale volume to 14000 mt in the coming season and also to double its sale turnover.
Basically there are two methods of harvesting: culling (sometimes called cull-harvesting)
and draining (drain-harvesting). The time to harvest depends partly on growth rate and
the size of animals you want to sell. This, in turn, depends on your market requirements.
It also depends on the pond management technique chosen. Cull-harvesting is used to harvest
market-sized animals from the pond at intervals and removes the faster growing
prawns. Annex 8 gives further information on size management. The rest of the prawns are
caught when the ponds are drained at the end of the grow-out cycle.
In tropical ponds cull-harvesting usually starts 5-7 months after PL have been stocked, or sooner if juveniles have been stocked. After cull-harvesting commences, you should totally seine each pond once per month or partially seine it twice per month (i.e. seine half the pond twice per month or all of it once per month). Take out the market-sized animals and sell them. Keep the smaller ones and soft-shelled animals in the pond for further growth. After about 8-11 months, drain the pond and sell the whole harvest. In areas where water supply is short, some farmers utilize water drained during complete harvesting in other ponds to conserve water but, if you think of doing this, beware that you may be transferring a water quality or disease problem from one crop to the next. This practice is not recommended in this manual. After drain-harvesting, you can either prepare, refill and restock the pond immediately, or keep it empty until you have enough water available again and/or (in temperate zones) until water temperatures become suitable again for rearing.
