Guide to Freshwater Shrimp Culture

Posted by EPa in Fisheries

Shrimp is the most important commodity, by value, in the international seafood trade. The shrimp industry has grown exponentially in the last decades, and growth is expected to continue for years to come.

A new and better technology to culture shrimps is being used by many enterprising shrimp farmers nowadays. Green water technology is a technique that cultures shrimps in water that is abundant in phytoplankton i.e. Chlorella, turning the water green hence, its name.

Pond Preparation

To prepare the pond, it should be dried and drained of water for three weeks until the soil at the bottom is cracked. The muck or the black soil at the bottom of the pond should be scraped off. Then the ponds are flooded with water and dried for another week. Hydrated lime at a rate of 2 tons per hectare is applied before the final flushing and sun drying.

When the pond is clean and dry, double hapa nets (10×10×1.5 meters) should be installed at the center of the pond. Bamboo catwalks from the dikes to the pens should be installed to facilitate easy feeding and monitoring of fish.

Water Culture/ Fertilization

After installing the pens, the ponds should be filled with water to a maximum depth of 1.0-1.2
