Phytoplanktonic populations of water in shrimp pond of Hormozgan province

Shrimp is one of the fishery products that are being developed in the world. The expansion of this industry has created challenges. Shrimp production in earthen pools depends on a variety of factors, including pool preparation, provide nutrition with appropriate composition and quality, nutrition management and water management. Nutrition plays an important role in the management of production and water quality. Nutrition cause accumulates nutrients and organic matter in the pools and then leading to the growth of phytoplanktons. Phytoplanktons are appropriate life foods in bottom and column water to feed shrimp larvaes, produce oxygen and refinement water. Therefore, the composition of the plankton population in water of ponds culture is very important. Some species at high densities can cause inappropriate quality, toxicity, oxygen depletion or even mortality in water. Knowing the type and composition of the plankton population in addition to being aware of production levels, population dynamics and life cycle of organisms will provide growth control, production capacity, quality water management and create sustainable production conditions.
