Problems solved by technology

[0006] The purpose of the present invention is to solve the problems existing in the prior art in the process of weighing and transporting sea bass fry with water in the process of dividing them into ponds, resulting in large calculation errors in the number of sea bass fry, low survival rate and low work efficiency after the fish fry are divided into ponds, and provides A water-free pond-passing method for sea bass fry. After the sea bass fry are anesthetized, they are weighed and transported without water when they are divided into ponds and passed through ponds, which can effectively improve the accuracy of fry number calculation and reduce the number of fish fry in separate ponds. Stress response during the seedling process, improve the survival rate of fry after pond division; at the same time increase the number of fry weighed and transported in a single time, thereby effectively improving work efficiency

Embodiment 1

[0032] Sub-pond water treatment in front of sub-ponds: The depth of the sub-pond water body is 1.5 meters. Disinfect the water body of the sub-pond with bleaching powder, and then cultivate algae and bacteria. The kind of algae culture is chlorella, and the kind of culture bacteria are lactic acid bacteria and bacillus.

[0033] After the sub-pond water treatment is completed, anti-stress treatment is carried out on the fry of the mother pond before the sub-pond: Sprinkle vitamin C preparation and glucose in the water body of the mother pond, once a day, for 3 days, and at the same time, the mother pond before the sub-pond The fry stopped feeding for 2 days.

[0034] Fish fry water-free pond-passing pond: the fish fry in the mother pond after anti-stress treatment are collected in a small water body after pulling the net, and then the collected fry are sampled and weighed. The number of samples is 3 times, and each sample is sampled. 50, calculate the exact size of fry. Set ...

Embodiment 2

[0038] Sub-pond water treatment in front of sub-ponds: The depth of the sub-pond water body is 1.5 meters. Disinfect the water body of the sub-pond with bleaching powder, and then cultivate algae and bacteria. The types of algae culture are chlorella and Scenedesmus, and the types of culture bacteria are lactic acid bacteria, bacillus, saccharomyces and photosynthetic bacteria.

[0039] After the sub-pond water treatment is completed, anti-stress treatment is carried out on the fry of the mother pond before the sub-pond: Sprinkle vitamin C preparation and glucose in the water body of the mother pond once a day for 4 days. The fry stopped feeding for 1 day.

[0040] Fish fry water-free pond-passing pond: the fish fry in the mother pond after anti-stress treatment are collected in a small water body after pulling the net, and then the collected fry are sampled and weighed. The number of samples is 3 times, and each sample is sampled. 60 tails, calculate the exact size of fry. ...

Embodiment 3

[0044] Sub-pond water treatment in front of sub-ponds: The depth of the sub-pond water body is 1.5 meters. Disinfect the water body of the sub-pond with bleaching powder, and then cultivate algae and bacteria. The types of algae culture are chlorella and Scenedesmus, and the types of culture bacteria are lactic acid bacteria, bacillus, saccharomyces and photosynthetic bacteria.

[0045] After the sub-pond water treatment is completed, carry out anti-stress treatment on the fry of the mother pond before the sub-pond: Sprinkle vitamin C preparation and glucose in the water body of the mother pond once a day for 5 days. The fry stopped feeding for 2 days.

[0046] Fish fry water-free pond-passing pond: the fish fry in the mother pond after anti-stress treatment are collected in a small water body after pulling the net, and then the collected fry are sampled and weighed. The number of samples is 3 times, and each sample is sampled. 70 tails, calculate the exact size of fry. An a...

Abstract

The invention discloses a water-free pond separation and pond transfer method for lateolabrax japonicus fries. The method comprises the following steps that water of sub-ponds is treated before pond separation; anti-stress treatment is performed on the fries in a main pond before pond separation; the fries are subjected to water-free pond separation and pond transfer; and the fries in the sub-ponds are fed and managed after pond separation. According to the method, after the lateolabrax japonicus fries are anesthetized, water-free weighing and transportation are adopted during pond separation and pond transfer, so that the accuracy of fry quantity calculation can be effectively improved, the stress reaction of the fries in the fry separation process is reduced, and the survival rate of the fries after pond separation is improved; and meanwhile, the quantity of fish fries weighed and transported at a time is increased, so that the working efficiency is effectively improved.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to a water-free pond-passing method for sea bass fry. Background technique [0002] Lateolabrax japonicus, scientific name: Lateolabrax japonicus, is a fish of the family Perchidae and the genus Lateolabrax. Body length, lateral flattening, large mouth, oblique. Mandible longer than maxilla, maxilla long, ending at posterior inferior edge of eye. The two crowns, pear bone, and palatine bone have villiform teeth. The posterior edge of the preopercle has fine serrations, the rear corner has a large spine, the lower edge has 3 large spines backward and downward, and the opercle has a large spine. With two dorsal fins, the first dorsal fin with the longest spine on the fifth fin. At present, sea bass is cultivated in a wide range in my country, but mainly in Zhuhai, Guangdong. [0003] The cultivation of perch can be divided into two stages, namely, the initial stage of seedlin...
