To estimate the density of fish farming, you first need to estimate the volume of the water body. The estimate of the water body volume is length × width × height. The final ÷1000 estimates the initial lift. According to the density of raising 1 cm fish in 1 liter of water, the total length of the fish cannot exceed the height of the water in the fish tank, and the number of some fish needs to be determined according to the species.
Estimation of fish density
To estimate the density of fish farming, you first need to estimate the water volume of the fish tank. Taking a 60×45×45 fish tank as an example, the water volume of the fish tank The volume is milliliters ÷ 1000, and the final number of liters obtained is 108 liters. Secondly, the fish tank must not be too full of water, as it can only hold about 95 liters of water at most.
According to the density of raising 1 cm fish in one liter of water, generally about 8 to 10 small and medium-sized fish are raised, and the length of each fish cannot exceed ten centimeters. By analogy, you can consider reducing the number of small fish and keep about 14 fish.
For giant fish, the stocking density needs to be determined based on the species of fish. Taking the above-mentioned fish tank as an example, only 15 3 cm seawater fish can be raised. However, if seawater fish grow faster , then the above-mentioned fish tank can support up to 8 fish.
