Scope

Main technical content: Fish fry and seedlings of bluefish, grass carp, silver carp, and bighead carp used for stocking in fish-and-fruit-mode ring ditches. This involves artificially releasing or transferring a certain number of fish fry and parent fish into public waters to increase their population size. **Weight measurement method for fish fry**: - Large-sized fish weighing ≥25 g/tail are subject to the weight method. - Five batches of fish fry are randomly sampled from each group. Three kg of fish fry are randomly selected from each sample for tail count, and the average weight of each sample is estimated. - The average weight of the five samples should deviate by no more than 10% from the target value. - Fish fry are weighed using a water-leakage device, and the total weight of the released batch is calculated. - Transportation vehicles: Use fully sealed live fish trucks or plastic oxygen bags for transportation. - The fully sealed live fish trucks should be equipped with oxygenation devices to ensure sufficient oxygen supply during transportation. - The plastic oxygen bags used for transporting fish fry should be double-layered non-toxic bags, with sufficient oxygen added during use and temperature control maintained during transportation. - Transportation water: Before transportation, the inner and outer surfaces of the transport boxes and their lids should be thoroughly cleaned and drained. Saltwater should be added before refilling, and the entire transportation process should involve surface antiseptic and anti-inflammatory treatments using salt at a final concentration of 0.2%. The water temperature should be controlled according to the fish fry's adaptability. - The fish fry should be stocked between June and July, with large-sized fish fry stocked during the lunar twelfth month. - Stocking should be carried out on clear, cloudy, or overcast days with wind speeds below level 5. - Stocking should be conducted near the ring ditch
