The video was filmed in a shrimp farm located in Hainan (China). The video shows the preparation of the ponds before stocking of the post larvae. There is a growing interest in organic food including organic shrimp. The driving forces behind the promotion of organic shrimp are mainly food safety and farm economics especially such farms rely on natural food in feeding.

Before stocking the shrimp post larvae, the management of shrimp grow-out farm targets the development of sufficient copepods bloom using a specific type of Probiotics as well as tea seed cake and rice bran. The use of tea seed cake targets the elimination of small unwanted fish if exist without the need to apply chemical disinfectants. It is believed that rice bran whether grinded or fermented rice bran would enhance more copepod development. The probiotic is applied based on the pH of the water.

According to published protocols, the water is pumped into shrimp ponds through 300-micron mesh for filtration. The aerators shown in the video operate for 7 to 10 days before the stocking of shrimp post larvae. The high aeration during the start-up is required to enhance the copepod bloom. The density of live food is checked to ensure a sufficient density before the stocking of shrimp post larvae.

This particular farm consists of four ponds of 2.5 mu each (one mu = 1666 m2) with a depth of 80 cm. The farm receives oceanic water from South China Sea. The water pH was 8 at noon.

Usually the PL15 of whiteleg shrimp, Litopenaeus vannamei are stocked at density which could range from 30-100 pcs/m2 depending on the intensity level.
