It is a misunderstanding to breed Penaeus vannamei with shrimp and shrimp

White shrimp culture has always been a phenomenon: in the early aquaculture shrimp is still small, do not feed white shrimp, but choose a slightly higher protein content of shrimp and shrimp feed.

In response, many people in the industry stated that it is not necessary for the raising of households to be misunderstood and disturbed by farming experience.

Dr. Xue Min from the Feed Institute of the Chinese Academy of Agricultural Sciences stated that the common white shrimp feed on the market today has a crude protein content of about 40%, which theoretically meets the nutritional needs of white shrimp growth in all stages. "The foreign white prawn feed protein content is even lower than in China, but it can still be improved."

Cheng Kaimin, the technical director of Guangdong Yuehai Feed Group Co., Ltd., also believes that raising households is not necessary. The use of 0# and 1# white shrimp feeds will not be bad if they are properly managed. Liang Chaochao, a farmer in Dagu Town, Jiangmen City, told reporters that he had never used grass and shrimp feed 0#, 1#, but instead used white shrimp feed. However, he still earned money in the past few years.

Mr. Su Shufeng of Guangzhou Chengyi Fish Technology Co., Ltd. stated that the nutritional requirements of white shrimp during seedling stage were indeed higher. However, feedstuffs in the water are eaten less by the white prawn. He laughed and said that there is an argument in the industry that small shrimp is mainly used in Feitang. He believes that raising households does not need to use higher-priced grass and shrimp feed, although the cost is not much difference, but after all, wasted. For the practice of cod liver oil in the middle and later stages of cultivation, Su Shufeng also disapproved. He believes that the added cod liver oil can not effectively adhere to the feed. Feed into the water, the oil density is lighter than water, floating up to form an oil film layer, hindering the exchange of oxygen in the water between the air, is not conducive to the growth of shrimp.

Most of the white shrimp were raised by the original grass and shrimp households. In the early stage of the promotion of white prawn, due to the lack of feed for white prawn, the raising household had to choose grass and shrimp feed. As a result, the white prawn had fast growth speed and high survival rate, and the cultivation was successful. "In fact, the breeding environment is good, and the disease is very good. Even if white shrimp is used, it can be cultured successfully." Su Shufeng said that the success at that time left a deep imprint on the experience of raising households. There are still many households affected by experience, and following the culture method of the year, they were fed with shrimp and shrimp feed in the early stage of white shrimp aquaculture.

With the expansion of white shrimp breeding, the environment has deteriorated, and diseases have increased. White shrimp are becoming more and more difficult to support. This also makes the farmers uncomfortable psychologically. “Shrimp farmers use grass and shrimp feeds that are uneasy.” Liang Zhuang, the feed distributor at Weizhou Island in Zhanjiang, said that many shrimp farmers believe that if they do not use higher protein feeds, shrimp will not be raised.
