Three key points for raising fish fry in autumn

Adjust the density and grade the rearing. After the beginning of autumn, choose suitable weather when the temperature is relatively cool, pull a net through the pond to sort the uneven-sized fry, and classify them as large (about 20 cm), medium (about 15 cm), and small (below 15 cm). Large-sized fry can be transferred to larger adult fish ponds with better conditions for mixed culture, while medium and small-sized fry are raised intensively in separate ponds. For stocking density, generally a pond with a water depth of about 15 m is stocked with 3000-5000 fish per mu. Fertilize according to the water condition and feed reasonably. For nursery ponds mainly raising silver carp and bighead carp fry, in addition to

Fertilize according to the water condition and feed reasonably. For nursery ponds mainly raising silver carp and bighead carp fry, in addition to fertilizing according to the water condition and maintaining suitable water fertility, it is also necessary to properly feed concentrated feed, that is, feed bran, cake meal, or compound feed at 9 a.m. and 4 p.m. every day, with 0.5-1 kg per thousand fry.

Strengthen management and focus on disease prevention. Autumn is the season when fish diseases are most prevalent, especially for grass carp fry, autumn diseases are the most serious. If disease prevention work is not strengthened, once fish diseases spread, serious losses often result. Therefore, always maintain inspections of the pond in the morning, at noon, and in the evening, observe the feeding and activity of the fish in the pond, and adhere to the "three fixed" practices in feeding (that is, remove residual feed promptly, regularly disinfect the feeding area and feeding platform, and regularly feed medicated bait for disease prevention and spray disease-prevention drugs).
