1, culture water quality
In the early stage of breeding yellow croaker, it is necessary to spray quicklime powder in the whole pond after cleaning the pond, and introduce tap water after disinfection and sterilization. It is necessary to pay attention to the cultivation of water quality under the premise of excessive care for wastewater and irrigation, and pour farmyard manure into the water surface to make zooplankton grow and develop.
Step 2 control density
Pseudosciaena crocea is a strong fish species with a strong eating rate. It likes to compete for ingredients, effectively control the relative density of large yellow croaker breeding, and the feed utilization rate can reach the maximum, 1 mu promotion 1 10,000 pieces, and the output is very shocking.
Step 3: Feed
Although yellow croaker can eat both meat and vegetables, it is recommended that you feed protein high-quality feed, such as fish, shrimp, loach, feed, vegetable cake, bean cake, cold skin bran and so on. Are fast fattening feeds for yellow croaker, which can greatly improve the quality and yield of yellow croaker.
Living habits of yellow croaker
Yellow croaker is a kind of warm water. The survival temperature is 0~38℃. The optimum growth temperature is 25~28℃, the pH value is 6.0~9.0, and the suitable pH value is 7.0~8.4. The level of hypoxia tolerance is average. Dissolved oxygen in water grows normally at 3mg/L, floats when it is less than 2mg/L, and suffocates when it is less than1mg/L. ..
Yellow croaker is a carnivorous omnivorous fish with carnivores as the main body. Foraging activities are usually carried out at night, and the food includes small fish, shrimp, various terrestrial and aquatic insects (especially chironomid larvae), small and medium-sized invertebrates and other aquatic arthropods, and sometimes small and medium-sized fish.
