Despite high profits, why do shrimp farmers in Nghe An still leave their ponds empty in the winter crop?

Market demand is high, shrimp prices are high, profits are good but very few shrimp farmers in Nghe An are bold enough to plant shrimp in this winter crop...
Up to this point, many shrimp farming households in Hoang Mai, Quynh Luu and Dien Chau towns have completed winter shrimp farming.

Mr. Nguyen Van Su in Quynh Loc commune (Hoang Mai town) has 11 ponds with an area of 2,500m2greenhouses, net houses. However, up to this point, he has only raised 5 ponds. Expected harvest on Tet holiday.

The pond temperature always ensures good growth and development for shrimp.

Accordingly, biological products are mixed with standard industrial feed, and waste is treated to meet standards before being discharged into the environment.

In addition, shrimp diseases are complicated, so in many places, shrimp are infected and dead. In the photo: Mr. Van Duc Duong's household in Quynh Dy ward (Hoang Mai town) said that he has released shrimp seeds in 3 ponds, but so far there have been dead shrimp, and they have to be scooped up regularly.

(Dien Chau), many shrimp farming ponds are being renovated and treated by people, waiting for Tet to release the seeds. Photo: Thanh Phuc
For winter shrimp, farmers often have to face many unfavorable factors, high risks due to complex changes in weather, unusual rain and floods. For shrimp to grow safely and achieve high productivity, farmers apply biosafety technology, raise shrimp in floating tanks, raise shrimp in greenhouses, and release them into the environment after reaching a good size, and carry out multi-stage farming. The farming process requires care techniques. When the temperature drops, it is necessary to reduce both the quantity and number of feedings; periodically check environmental factors every day in the morning and afternoon. If the environmental factor index is outside the appropriate threshold, immediate measures must be taken.
