Penaeus vannamei raises fears for this year's breeding situation

On the afternoon of April 25th, Bayer's South American white shrimp aquaculture technology patrol will be conducted again. One of Thailand's designated experts in shrimp culture. Danny (Soraphat Panakorn), at the invitation of Bayer (Sichuan) Animal Health Co., Ltd., exchanged experiences on breeding techniques, management, and diseases with farmers at the White Dolphin Hotel in Qinzhou, Guangxi.

“Shrimp is desperate, not starving.” Danny's analysis of the key to feeding in culture was conducted at the symposium. He believes that overfeeding not only increases production costs, but also that algae overproduce, circulation and algae, water quality instability, fluctuations. Big, because 70% of the farmers feed according to the feeding table provided by the feed company, he suggested that in the aquaculture process, the first month of feeding should be done without feeding the aerator, and the small amount of meals in the first month is better. The first meal of the day is fed after the sun rises for an hour.

In addition, for conventional feeding techniques, he suggested that: First, only feed 80% satiety; Second, adjust the feeding time flexibly according to environmental conditions; Third, multiple meals during the day, "half meal" at night; Fourth, low temperature Stop at 20 degrees or above 34 degrees.

It is reported that most of the participants in the symposium were the South American white prawn farmers in the Qinzhou region, with about 250 people, of whom the majority were Zhejiang. Some white penaeid shrimp farmers have learned that the current release of seedlings is still relatively small, and many South American white shrimp farmers are concerned about this year's South American shrimp culture. They hope to re-emergence at the end of April or at the beginning of May. “Now the salinity is relatively high, if more rainwater may be better for the seedlings.” Since the success rate of general breeding in the freshwater areas was higher than that in saltwater areas last year, Jinzhou’s gold boss is also worried about this, “because we are all raising Large-size white shrimp."
