Model extensive shrimp farming high productivity improvement

Shrimp pattern in the form of extensive past tradition for high yield (about 200 - 300 kg / ha / year). Since farmers access shrimp culture techniques in the form of improved extensive shrimp high yield (QCCTNSC) So far, ponds of farmers achieved very positive results.

Shrimp production QCCTNSC affordable, close to the people, not technically demanding as industrial shrimp farming that economic efficiency, suitable for families. Initially, farmers need the right dress pond techniques. Ca Mau Extension Center recommends people draining ponds, lime CaCO3, dry cracked feet bird pond; then take water into the pond reaches 1.2m, after 3 days of trash fish kill and kill bacteria. National seed before stocking, stocking density 6 / m2. During the run, feeding in food industry, the dose of 1 kg / day and increased by 10% the next feeding. Every day, farmers need to check and deal with environmental factors such as pH, alkalinity, water color, clarity ...

The Extension Center of Ca Mau said, by this time, shrimp farming pilot QCCTNSC basic U Minh district has implemented successfully. Shrimp was 4 months old, the output is estimated at between 800 - 900 kg / ha (sizes 35-40 / kg), the survival rate is about 60%. Continue to feed for 01 months for harvest, production is estimated at over 1 ton / ha, the average income per household rate from 70-88 million / ha.

According Do Ming Chong, living in clusters 2, U Minh town, the first month, the shrimp will find natural food; through the second month, conducted feeding supplemented by food industries; regularly add vitamins and minerals to increase resistance to shrimp. In particular, it should be based on the environmental situation, weather and health food shrimp to adjust appropriately, check the status of swimming, liver, pancreas, parts of ... the shrimp to promptly handle if there is a problem occur. In addition, during feeding food supplement industry, he also used garlic, bitch tree, ripe banana, honey ... to mix in shrimp feed to help digestion. After 4 months of culture, his shrimp Chong weight gain around 40con / kg, estimated yield of 1.2 tonnes / ha, except for the household expenses he collected more than 70 million profit.

The success of the model of tiger prawns extensive improvements show that when farmers know technical applications in ponds will reduce a lot of risks, as well as protect the environment and create quality products high. The success of the model will be a prerequisite for replication of the black tiger shrimp farmers in Ca Mau province.
