What are the key technical points for autumn fingerling management?
Pond clearing. Transfer the fingerlings into a pond that has been cleared and disinfected for rearing. If water source and pond rotation are difficult, all fingerlings can be transferred out for temporary holding, then the original pond disinfected with 75 kg to 100 kg of quicklime per mu, and the water quality fertilized by conventional methods; once the lime's potency has dissipated, transfer the fingerlings back. Separate rearing. Adjust and separate the fingerlings according to different sizes so that the fingerlings stocked in the same pond are of uniform size. Large fingerlings have a big appetite and strong food-grabbing ability; if small fingerlings are stocked in the same pond, the small fish will decline in condition because they cannot get enough feed.

What measures are there to ensure the supply of fish fry and fingerlings?
Purpose and application: In response to problems such as severe damage to farmed fish fry and fingerlings in disaster areas and tight supply, countermeasures such as strengthening breeding and collecting broodstock are proposed to make every effort to ensure the supply of fry and fingerlings. Technical measures: 1. Gather statistics to understand the quantity of fry and fingerlings needed for restoring production in the region and the fry and fingerling production capacity, identify the shortfall in fry and fingerlings, and contact fry and fingerling production farms as early as possible to supplement high-quality healthy fry and fingerlings for restoring production. 2. Pay attention to understanding and grasping market information on broodstock and do a good job of collecting broodstock.

Autumn management of fingerlings takes know-how: these key technical points must be mastered
1. Clear the pond in good time. After 2 to 3 months of rearing fingerlings, pond water quality generally has deteriorated, natural food organisms have decreased, and harmful gases such as hydrogen sulfide and pathogenic bacteria have increased. After the beginning of autumn, the fingerlings should be transferred to a pond that has been cleared and disinfected for rearing. Where there are difficulties in water supply and pond rotation, all the fingerlings can be transferred out for temporary holding, then the original pond should be disinfected with quicklime at 75 kg to 100 kg per 667 sq m, and water quality should be fertilized by conventional methods; after the efficacy of the lime has dissipated, transfer the fingerlings back to ensure purification of their living environment.
