The mandarin fish farming cycle is divided into 3 stages: fry rearing, fingerling rearing and grow-out farming
Abstract The mandarin fish farming cycle is mainly divided into the fry rearing stage, the fingerling rearing stage and the grow-out farming stage. Fry rearing stage: artificial induced spawning and artificial incubation are carried out. Fingerling rearing stage: after the mandarin fish fry hatch out of the membrane, a sieve net should be used to screen out the egg membrane, dead eggs and other debris, and then

Daily Testing Methods and Key Points During the Shrimp Grow-Out Period
Shrimp farming technicians should patrol the pond once in the early morning and once in the evening each day, carefully observing changes in the pond environment, water color, and the safety of shrimp activity, and keep records. The main testing contents are as follows: 1. During the grow-out period, viral pathogen testing should be carried out frequently, using methods such as T-E staining, nucleic acid probes, and PCR. 2. Remove crabs and rodents around the shrimp pond. Strictly prevent the introduction of dead shrimp from other shrimp ponds and water discharged from diseased shrimp ponds. 3. Measure water quality factors such as water temperature and dissolved oxygen. Daily

How to raise red drum (Sciaenops ocellatus)? Detailed explanation of the key points of grow-out techniques
Pond culture (1) Conditions and requirements of the culture pond. The area of a grow-out pond is generally 5-10 mu, preferably 3-5 mu, and a water depth of 1.5-2.5 m is suitable. The soil is best as sandy loam, dissolved oxygen must not be lower than 6.5 mg/l, ammonia concentration ≤0.3 mg/l, and pH 7.5-8.5. (2) Preparation before stocking. Carry out repair and disinfection of the shrimp pond according to general marine culture specifications, fill with new water, and fertilize to cultivate water quality 7-10 days before releasing the fry.
