What are the suitable seedling specifications and stocking density for cage culture of rice field eels?
Q: For cage culture of rice field eels, what size seedlings and what density should be stocked?
A: For rice field eel seedlings, choose wild-caught ones taken by cage trapping, with yellow body color, free of disease and injury, and strong movement; the general size requirement is 30-40 eels per kilogram. Before stocking, disinfect the eel seedlings by soaking them in 3% salt for 5-8 minutes, or in 20-30 mg/L povidone-iodine for 10-15 minutes. When the water temperature is 18-25 degrees, choose a sunny day to stock the eel seedlings. According to water temperature and weather conditions, stock before the end of April to July. The stocking density should be determined by the area of the floating rafts of aquatic plants in the cage. Generally, for each square meter of floating raft, 2-2.5 kg of eel seedlings can be stocked.
In addition, in the pond where the cages are placed, some bighead carp and silver carp can be stocked together, which can purify the water quality and increase production.
