Embodiment Construction

[0025] refer to Figure 1 ~ Figure 3 , the present invention is a kind of ovum retrieval device for hatching fish, comprising a fixing device 1 for fixing fish and an insertion tube 3 for ovum retrieval, a port of the insertion tube 3 is connected to an egg collection cup 6, and an egg collection cup 6 is connected to the insertion tube 3. A flushing pipe 4 is provided, and the flushing pipe 4 is connected with a water supply device, and the outlet end of the flushing pipe 4 faces the mouth of the fish.

[0026] The insertion tube 3 provided with the egg retrieval device for hatching fish is connected to the egg collection cup 6, the insertion tube 3 stretches the mouth of the fish, and the insertion tube 3 is provided with a flushing pipe 4 to flush water or sea water to the mouth of the fish to make the fertilized eggs It flows out smoothly and is collected by the egg collection cup 6, which ensures the simplicity and integrity of egg retrieval. The fixing device 1 is used t...

Abstract

The invention discloses an oral incubation fish ovum picking-up device and method. An insert tube arranged on the oral incubation fish ovum picking-up device is connected with an ovum collection cup. A fish mouth is opened by the insert tube, and water or seawater is flushed into the fish mouth through a flushing tube arranged on the insert tube, so that fertilized ova smoothly flow out and collected by the ovum collection cup, and a convenience and integrity of ovum picking-up are ensured; a fixing device is adopted for fixing parent fish, so that operation is easy, convenient and efficient, the phenomena that fish bodies are not fixed firmly when fixed directly by hands and follow-up ovum picking-up is affected are avoided, and the working efficiency and working quality are improved. The oral incubation fish ovum picking-up device is applicable to the field of aquaculture.

Description

technical field [0001] The invention relates to the field of breeding, in particular to an egg retrieval device and method for mouth hatching fish. Background technique [0002] At present, hatching with eggs in the oral cavity is a unique reproductive method for fish. There are many species of fish that are bred by oral hatching, including Osteoglossus and several genera of Cichlidae such as Peacock, Cichlid, and Tilapia. Among them, tilapia, as a cultured species highly recommended by the Food and Agriculture Organization of the United Nations, has become an important global cultured fish, and among tropical ornamental fish, about 1 / 4 species belong to the family Cichlidae. Oral hatching has two characteristics: one is that the incubation time is longer, at least one week; the other is that the number of eggs laid in each batch is small, generally less than 100. Because the broodstock cannot ingest food during the egg-bearing period, it causes malnutrition, decline in ph...
