In Aquaculture, let us know in detail about the precautions to be taken by the farmers in the cultivation of Vannamei and the present Vannamei prawns farming.
Vannamei prawns are in good demand in the global market.
So a successful crop yields a good profit.However this species has many serious viral diseases.
So other scientific proprietary approaches along with virus management are needed to reap a profitable harvest.
Prawns mostly live at the bottom of the pond.Natural food produced there.So the bottom part quality of the pond is also very important in Prawns farming.Dry the pond soil until it is well cracked.Plow the pond twice.
Doing so will cause the organic matter accumulated at the bottom of the pond to decompose quickly.The production of harmful gases during harvest is reduced.
Soil pH The use of lime should be determined according to the value.Fill with water and apply 100 kg of bleaching powder per acre after one day.Sprinkle calcium oxide dolomite at the required level of full alkalinity less than about 100 ppm.These dosages vary.The pH of the water should also be checked when using these.Zinc should be sprinkled on the bottom of the pond to grow enough plankton to grow natural food.
Adequate amounts of minerals needed for plankton production in water can be used.The water should be filled to a depth of 5 feet.
Children Prawns should be abandoned in the morning or evening.Children Prawns should make sure that there is an adequate concentration of oxygen in the pond before leaving.
Oxygen concentration can be increased by placing it in pre-aerators if necessary.Leave the baby bags in the pond for up to half an hour before the children drop out and set the pond temperature to VH.Should be corrected.Then gently drop the child into the pond.
Seed survival percentage should be calculated 24 hours after leaving up to 100 offspring in one or two hapas kept in the pond.
