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.
3. Strengthen broodstock breeding, appropriately increase feed with a higher protein content, and add nutritional immune enhancers such as vitamin C, so as to promote the normal development of broodstock as quickly as possible, improve maturity, and ensure that production capacity does not decline.
4. Strengthen the collection of large-sized fish as broodstock through multiple channels such as reservoirs or deep-water mountain ponds, strengthen breeding, and strive to enable fry farms and other fry and fingerling systems to resume production as soon as possible.
5. After the weather turns warmer, the aquaculture water level can be appropriately lowered so that the water temperature rises faster and the gonadal development of broodstock is promoted.
