What are the key points to note in turbot farming?
Turbot is an emerging farmed fish species. Turbot originated in the Atlantic region, has extremely high nutritional value, has excellent beauty and skin-nourishing effects, and its market price is also relatively high. However, after artificial farming, its growth cycle is shortened, but certain conditions are required, so what should be noted during artificial farming? Let's take a look with Qinnong.com.
1. Water quality regulation
Water quality is the key point in turbot farming. Turbot is a cold-water fish, with a suitable growth temperature between 10-23 degrees, and it grows fastest between 15-19 degrees. During the farming period, the water circulation volume should be appropriately increased to achieve a good waste discharge effect and promote clean and clear water quality. In addition, a high-dissolved-oxygen environment should be created. A high-dissolved-oxygen environment is beneficial to the growth of turbot, and can also improve its anti-stress response and reduce the probability of fish diseases.
2. Seedling selection and purchase
Seedlings are also a key point in turbot farming. Good seedlings determine the future economic returns of turbot. When purchasing, try to choose fry of more than 5 cm, and the place where the fry are purchased must be legitimate. The fry should have a smooth and streamlined appearance, with no damage or disability on the surface. Do not choose fry with a dull body and albinism, as such fry carry disease. Then look at the condition of the gills to see whether the gill filaments are neat, and check whether there are parasites on the back.
3. Farming density
The farming density of turbot should be judged according to the growth stage of the fish and the scale of farming. If the farming density is too high, it is not easy to manage and can easily cause diseases, resulting in mass death of fish; if the farming density is too low, it is not conducive to water quality management, wastes farming space, and leads to low yield and low returns. Therefore, during farming, attention must be paid to this farming density. Neither too dense nor too sparse, maintaining an appropriate farming density can minimize the risk of disease and maximize returns.
4. Feeding management
During artificial farming of turbot, the freshness of the bait must be ensured. Do not feed deteriorated or moldy bait. In addition, feeding must be done at fixed times and in fixed amounts. In summer and autumn when the temperature is relatively high, the water temperature begins to rise. At this time, the feeding and digestion ability of turbot improves, and it is in a period of rapid growth. At this time, the feeding of bait should be increased to make it grow quickly. Generally, feeding should be done 3-4 times a day. Because the temperature is too high at noon, its appetite will decline, so increase the feeding amount in the morning and evening, avoiding the high-temperature period.
5. Disease prevention and control
Although rising water temperature is a period of rapid growth for turbot, it is also a period of disease outbreaks. At this time, special attention should be paid to disease prevention and control work. The water body should be disinfected regularly, and careful observation should be made. After discovering disease, first isolate the diseased fish, then disinfect the water body, and after determining which disease it is, apply the appropriate treatment.
