Abstract
The invention relates to the technical field of aquaculture, and particularly relates to a method for measuring the required optimum temperature of fish. The method includes: averagely putting the same kind of fishes in B water tanks having the constant temperature T0 and enough and constant oxygen to breed till domestication; weighing each fish and the weight of food m0 eaten by the fishes in the condition of a suitable environment and enough oxygen; and setting different temperatures, and measuring the temperature corresponding to the maximum eaten food as the required optimum temperature of the fish. The method for measuring the required optimum temperature of the fish can accurately measure the optimum temperatures of all the kinds of fishes, can provide references to aquaculture aeration, and can reduce resource waste.
Description
Technical field
The present invention relates to cultural technique field, and in particular to a kind of method of optimum temperature needed for measurement fish.
Background technology
Most it is exactly directly regimen with fish relation except ground condition during day during aquaculture.Water it is cold
Warm, sound is pure and impure, and oxygen dissolved etc. all affects the growth of fish.Fish is emotionally stable under the environment that water temperature is adapted to, energetic,
Honey stomach, when water temperature exceedes preference temperature, fish is not in the mood for seeking food, and when water temperature is less than preference temperature, fish then becomes stiff slow
It is stagnant, have no appetite.Can actually temperature can be just how much fish preference temperature, any method measurement is not seen reported till now
The method of optimum temperature needed for fish.
The content of the invention
After the present invention considers to present aquaculture production present situation, it is proposed that optimum temperature needed for one kind measurement fish
Method.
Technical solution of the present invention：
