Fish fry cultivation, also known as "Fat Pond", refers to the fish fry that grow to about 3 centimeters after 20-25 days, and are called "summer flowers". important. At this stage, perch seedlings are generally cultured in nursery boxes. Due to the high requirements for the growth environment required by perch seedlings, regular water changes and water temperature maintenance are required. There are two disadvantages in using nursery boxes for breeding. One is that it is inconvenient to change the water; the current water change methods generally include two types, one is to put water on one side of the nursery box and add water to the other side. This water change method ensures that the growth environment of the fry remains unchanged, but it takes a long time And waste water resource; Another kind is to directly change water body after fry is taken out, though this mode can change water fast, can cause damage to fry when picking and placing fry, is unfavorable for the growth of fry. The second is that the existing nursery box cannot conveniently adjust the temperature of the water body; perch fry need to grow normally in a suitable water temperature, and perch can normally forage and grow when the water temperature is above 14 degrees Celsius, and it is easy to die when it drops to a critical 7 degrees Celsius , The survival temperature of perch is between 2 and 20 degrees Celsius, so it is necessary to control the water temperature in the nursery box at 14-20 degrees Celsius to ensure the safe growth of fry.
