Turbo Ling comes from the United Kingdom, France and other European countries in the northern Atlantic Ocean and is a benthic fish. China introduced turbot in artificial breeding in 1992 and has now developed to a certain scale in Shandong and other places. Turbot meat is tender and has high nutritional value. It is popular with consumers and has a promising development prospect. This article gives a brief introduction to the basic techniques and conditions of turbot breeding. 1. Seed purchase: The body length of turbot seedlings should be more than 5 cm. The fish body should have normal color, vitality, and no disease or deformity. Second, the water temperature: turbot is a cold water fish, breeding suitable water temperature requirements between 10 °C ~ 20 °C, 14 °C ~ 17 °C water temperature for the rapid growth phase. 3. Salinity: The suitable salinity for turbot culture is between 20 ‰ and 32 ,, and 25 ‰ ‰ 30 ‰ is most suitable. Fourth, water quality: turbot breeding requirements of water quality without pollution, extraction of underground seawater can be directly used in aquaculture ponds, use of seawater to be filtered and sterilized. V. Water consumption: According to the culture experience of turbot, it is better to use water culture. The amount of water changed every day is at least 5 cycles. If the amount of water is sufficient, it can be doubled. Six, growth rate: turbot growth speed, according to farming experience, under normal circumstances from the body length of 5 cm seedlings into the tank calculation, 7 months that is more than 200 days can be grown to a weight of about 500 grams per tail, to achieve product specifications . Seven, bait: The main bait of turbot is to use soft fish as binder and fish meal, various vitamins and special powder feed to make soft pellets. The finer the bait, the better the growth effect. Eight, bait coefficient: turbot habits cluster undercover, usually rarely swimming, food intake is small, the bait coefficient is between 1:1 to 1:1.5. Feeding amount on day nine and daily: The body weight is 200 grams or less within 3 days or 4 times per day, and the body weight above 200 grams is 2 times or 3 times per day, and the body weight is between 300 grams and 400 grams per day and 2 times per day. It is 1.5% to 2% of fish weight. Ten, advocate shed raising. Building greenhouses to raise turbot, less investment, good results, winter can be insulated, shade in summer, so that the temperature inside the shed cool, suitable for turbot growth. Eleventh, clear pool: turbot culture requires clean and non-polluting water quality, the pool should be cleaned once in 2 days to prevent the bait and fecal material residues cause bacteria to multiply. 12. Medicinal bath: In order to prevent hidden diseases, it is required that the cultured fish should be given a medicinal bath every 10 days to 12 days. The formaldehyde concentration should be 1:6000 to 1:5000, and soaked for 1.5 to 2 hours. XIII. Inflation: The aquaculture tank should be continuously inflated. A gas stone can be used for every 3 to 4 square meters, especially during the medicine bath. XIV and treatment of major diseases: turbot farming is mainly found in the following diseases: 1. vibriosis: This is the turbot common bacterial disease, congestive symptoms in the fins, body surface ecchymosis, and skin Muscle tissue bleeding or intestinal inflammation, etc., can be fed antibiotic baits for treatment, generally the amount of medication per kilogram of body weight of 75 mg to 100 mg. 2. Trichodinosis: It is a common parasitic protozoan parasitized on the axilla and the body surface and can be killed by a formalin bath at a concentration of 1:6000. Turbot is a relatively high-quality fish that is suitable for breeding. It has developed rapidly in recent years, especially in greenhouses, and it is adapted to the culture of turbot. Due to the lack of understanding of the living habits of turbot in many farmers, some detours have been made in the breeding industry, causing some economic losses. If you can grasp these practical technologies, you will certainly gain something.
