Embodiment

[0007] A total of 9 cages are used, the size of the cages is 6m×6m×6m, and each cage contains 800 fish. Control group S0 (normally fed every day), S1F6 (starved for 1 day, resumed feeding for 6 days), S2F5 (starved for 2 days, resumed feeding for 5 days), three net cages in each group; the breeding time was four months, Feed twice a day during the feeding period. The selected red-finned puffer had an initial weight of 400 grams, and each group of red-finned puffer was denoted by S0, S1F6, and S2F5 respectively.

[0008] Result shows, with the puffer puffer that the method for embodiment of the present invention cultures, the average body weight of S1F6 (1 day of starvation, resumes throwing something and feeding 6 days) group is greater than normal body weight; The average body weight of the group was smaller than that of the normal feeding group (see Table 1).

Abstract

The invention discloses a cage culture method of takifugu rubripes. In the cage culture process of the takifugu rubripes, fasting of one day and feeding of continuous six days is a cycle and feeding two times per day to satiation during the feeding period, so that the labor is saved, thereby reducing the investment of labor cost. The food conversion ratio of the takifugu rubripes is high with refeeding after starvation. Compared with the fish pond with regular feed, the bait investment is reduced, and the growth speed is faster than that of the single body with continuous feed per day.

Description

Technical field: [0001] The invention relates to a net cage culture method for red-finned puffer, in particular to a net-cage culture for red-finned puffer which can not only promote the rapid growth of red-finned puffer, reduce the amount of bait fed, but also save labor and reduce breeding costs method. Background technique: [0002] Redfin puffer is one of the puffer fish with the least toxicity and the best meat quality and quality. At present, the original species has been introduced for breeding and self-propagation. The preserved species has been produced stably and in large quantities in my country for a long time, meeting the needs of the international market. Create more breeding varieties and farming opportunities for the majority of farmers. However, the traditional redfin puffer is cultured in cages, and it is fed with bait twice a day until it is full. There are disadvantages such as high labor intensity and high breeding costs in the culture. Invention conte...
