1. Oyster is the fattest in the Qingming period of the following year in June 5438+February, but its market time is165438+1October to May of the following year. Since oysters are generally stocked in May and can be caught in about six months, they can be eaten in June from 5438+065438+ 10. However, after entering June 5438+February, the weather began to get cold, the consumption of oysters was low, and the energy accumulation was high, so the meat quality of oysters was relatively fat until next year in Tomb-Sweeping Day.

2. Oysters are oysters, and their seedlings come from semi-artificial seedling collection. Oysters can mature and reproduce after one year of gonad development. The gonad of oyster is mature, and the peak spawning time is at 24 ~ 25℃. The breeding peak of oysters in Xinghua Bay, Putian is from May to June, and most of them lay eggs in flood season. The temperature in the sea area is suitable. The fertilized eggs of oyster develop into D-shaped larvae within 20 ~ 22 hours, and the average shell length of the larvae is more than 280μ m. When the larvae have 40% ~ 50% eye spots, they can be put in to make the larvae attach abnormally. Based on many years' experience, aquatic technicians in Xiuyu District have tested oyster seedlings in this sea area. Once the oyster seedlings are mature, they will be sent through the platform to guide farmers to put the attachment base in time.

3. Generally, its seedlings can be picked from local materials, and oyster shells are used as seedling pickers, with low cost. According to years of experience in seedling collection, oyster seedlings grow vigorously and in large numbers from May to mid-June every year. Inspection of seedling picking effect: when picking seedlings, we often go out to sea for inspection, and we can see oyster seedlings with pinhole size 3 ~ 5 days after sticking seedlings. If barnacle seedlings are attached, they should be cleaned in time and picked again. Don't miss the seedling picking season.
