Embodiment 1

[0043] A novel lean fish culture method is characterized in that it comprises the following steps:

[0044] S1. Select healthy mature fish that are suitable for slimming and breeding, and carry out disinfection treatment and pre-breeding before breeding;

[0045] S2. Temporary cultivation in the earth pond, put the pre-raised mature fish into the earth pond for temporary cultivation and purification;

[0046] S3. Purification of non-earth ponds, transfer the fish that have been temporarily raised and purified to the non-earth ponds for 15 days of running water exercise, during which no feeding is carried out;

[0047] S4. Fishing and listing;

[0048] In the step S2, during the temporary maintenance and purification process, food and water were stopped for 30 days, during which time the fish was stretched for 5 times with an interval of 6 days to make the fish lose weight.

[0049]In the present invention, the benign stress response of fish is used in the process of temporar...

Embodiment 2

[0068] The present embodiment adopts the same novel slimming fish breeding method as in Embodiment 1, the difference is that

[0069] S2. Temporary cultivation in the earth pond, put the pre-raised mature fish into the earth pond, and carry out temporary cultivation and purification; during the temporary cultivation and purification process, stop eating and hanging water for 35 days, and exercise by pulling the net 5 times during the period, with an interval of 7 days. Fish to lose weight.

[0070] S3. Purification of non-earth ponds. The fish that have been temporarily raised and purified are transferred to the non-earth ponds for 18 days of running water exercise, and no feeding is performed during this period.

[0071] Further, the slimming fish is grass carp.

[0072] Both the earth pond and the non-earth pond are equipped with aeration equipment to ensure that the dissolved oxygen content of the water quality during the cultivation process is 7 mg / L.

[0073] The net-dr...

Embodiment 3

[0076] The present embodiment adopts the same novel slimming fish breeding method as in Embodiment 1, the difference is that

[0077] S2. Temporary cultivation in the earth pond, put the pre-raised mature fish into the earth pond, and carry out temporary cultivation and purification; during the temporary cultivation and purification process, stop eating and hanging water for 15 days, and exercise by pulling the net 3 times during the period, with an interval of 5 days. Fish to lose weight.

[0078] S3. Purification of non-earth ponds, transfer the temporarily purified fish to non-earth ponds for 10 days of running water exercise, during which no feeding is performed.

[0079] Further, the slimming fish is grass carp.

[0080] Both the earth pond and the non-earth pond are equipped with aeration equipment to ensure that the dissolved oxygen content of the water quality during the cultivation process is 6 mg / L.

[0081] The net-drawing tool is a net-type net-drawing tool.

Abstract

The invention belongs to the technical field of fish farming, and provides a novel slimming fish farming method. The method includes the following steps: S1, selecting healthy mature fish suitable forslimming farming, and performing disinfection and pre-farming before raising; S2, performing temporary raising in a soil pond, putting the pre-farmed mature fish in the soil pond to perform temporaryraising and purification; S3, performing non soil pond purification, and transferring the fish through temporary raising and purification to a non-soil temporary raising pond to perform running waterexercise for 10-21 d without feeding the fish during this period; and S4, catching the fish to transport to markets, in the step S2, during temporary raising and purification, stopping giving food and water to the fish for 15-45 days, and performing fishing net pulling exercise for 3-9 times during this period so as to make the fish lose weight. Through the utilization of the benign stress response of fishes during soil pond temporary raising and non soil pond purification, the slimming speed of the fish can be accelerated, the slimming effects of the fish can be effectively improved, and thevisceral ratio of the fish can be effectively reduced.

Description

technical field [0001] The invention belongs to the technical field of fish farming, and in particular relates to a novel method for cultivating slimming fish. Background technique [0002] "Slimming fish" is the process of starving commercial fish with fat abdomen grown in conventional ponds in flowing clean water for several months to achieve rapid weight loss. The "slimming" commercial fish has the characteristics of bright body color, strong body, no muddy smell, less fat, less drug residue, good taste, and good quality. With the improvement of people's living standards, the pursuit of high-quality fish has also increased, and the demand for "slimming fish" in the catering industry has grown exponentially. However, in the existing technology, "slimming fish" usually needs to be cultivated for 4-6 months before it can be launched on the market. The slimming effect is uneven, and it is difficult to meet the needs of the industrial chain. [0003] The stress response of f...
