Embodiment Construction

[0015] The method for keeping marine fish without water of the present invention will be described in detail below by taking flounder fish as one of the specific embodiments.

[0016] (1) Selection: pick out the fish with scars and poor vitality, and select the healthy and vigorous flounder fish with good physique.

[0017] (2) Domestication: domesticate the selected flounder in seawater for more than 48 hours without feeding, so that the food in the digestive tract can be basically digested and discharged, and its oxygen consumption and stress response can be reduced. At the same time of domestication, gradually start to lower the water temperature in the way of gradient cooling. The cooling rate is less than or equal to 2 °C per hour above 10 °C; below 10 °C, the cooling rate is less than or equal to 0.5 °C per hour. Let the flounder gradually adapt to the low temperature environment, so as to keep alive at low temperature in the later stage.

[0018] (3) Oxygenation withou...

Abstract

A waterless activation method of the see fishes. Keep the sea fishes in the pure oxygen condition on the waterless state by domesticating without food and episodic gradiently cooling process, the sea fishes can be alive for a long time and reactivated in the fresh seawater. The invention can make some sea fishes be alive for about 60 hours, and the weight of the fish is only lost of 2.4 percent, so the active effect is good, it improves the fresh activity and accumulating of the sea fishes oberviously, and has the great acceleration significance to the development of mariculture.

Description

technical field [0001] The invention relates to a method for keeping marine fish alive, in particular to a method for keeping alive and transporting marine fish under low temperature conditions without water. Background technique [0002] With the continuous development of the aquatic product breeding industry, the requirements for the preservation technology during the transportation of aquatic products are also getting higher and higher. Fishery developed countries such as Japan have successively applied the ecological ice temperature technology to the research of long-distance anhydrous transportation of some marine animals. Our country has also begun to carry out some researches in this respect. In the "Qilu Fishery" magazine, it has been reported that the low temperature preservation technology was used to preserve Philippine clams and Japanese prawns, etc., and the survival rate was relatively high. [0003] As for marine fish, the research in this area is still blank...
