An Integrated Aquaculture Freshwater Prawns and Rice

Agriculture, Fisheries and Forestry decreases due to growing needs for industrial land and housing makes thinkers and engineers in the field of fisheries must think hard to optimize production. However all the people always need food, because it is in line with the growth of population, as well as the growing demand for food.
So that in our country, farmland must be enabled as well as fishing grounds. throwing one stone two birds falling, that's a term mentioned

one of which is an integrated aquaculture freshwater prawns and rice to increase land productivity.
This way mentioned will not reduce the productivity of rice and will get additional revenue from prawns.

feces produced freshwater prawns contain a variety of nutrients will become fertilizer, so fertilizer costs can be reduced.

Construction

Preparation is done in construction is to create a channel around the rice fields, raising dikes, and expansion of the inlet channel called kobakan. size is as follows:
