Shrimp farming is very profitable and it is one of the important and valuable species of fish. It is a water animal without any backbone. The total fish and fish products produced and exported per year, 65 percent of those are shrimp or shrimp products. Millions of dollar comes to our country by exporting fish and fish products. A large portion of that income comes from shrimp. The ratio of total fish farming production and shrimp production is 41 : 25.
Probability of Shrimp Farming
There are about 0.22 million hectors of shrimp cultivable land in the tropical southern area of our country. This types of land is very suitable for shrimp farming. About 0.11 million hectors of those land are being used for shrimp farming using the traditional shrimp farming methods. Where the farmer can produce highest 180 to 200 kg of shrimp on an average per year. Which is comparatively very low than other countries. But by using modern shrimp farming methods, producing 5 to 6 tons of shrimps per hector is possible within 6 months. Only a few number of farmer in our country has started using this shrimp farming method, and they are getting the benefits of it. If this method can be spread through the whole country then we will be able to earn millions of dollar per year.
Species of Shrimp
There are about 60 species of shrimp available in our river and sea area. A few species of those species are very suitable for shrimp farming and those are very profitable. Among those, lobster and prawn are most profitable for farming. Lobster is cultivated in freshwater. They become big sized and weights between 250 to 400 grams. Among the saltwater shrimp, prawn is cultivated in a plenty. It is known as “black tiger” to the farmer. A little description about this two types of shrimp are described bellow.
