Description
Technical Field
The invention relates to a breeding technology, in particular to a high-efficiency artificial spawning device for snout breams in the transverse bands.
Background
Lutjanus latus (Hort.) Merr (Lutjanus latus (Merr.))Hapaloyenys mucronatus) Commonly called copper basin fish, sixteen fish, etc. Is an economic fish of islands and reefs, is deeply favored by consumers and aquarium enthusiasts due to the advantages of high meat yield, compact meat quality, delicious taste, rich nutrition, beautiful stripes and the like, and is a marine economic fish with great edible value and ornamental value. However, the wild resources are less, the fish-bearing period is not obvious, the fish catch amount is lower, and the market supply is short. At present, the market price of the rhabdosarus punctatus is about 200 yuan/kg, the rhabdosarus punctatus is mainly derived from wild fish caught by sea or wild fish fries cultured in a net cage, and no reports of artificial breeding fries cultivated and sold by units or individuals exist. A large gap meeting market demands is bound to be taken on an artificial breeding road, and a large amount of high-quality oosperms are obtained firstly when an artificial breeding technology is realized. Therefore, the artificial spawning induction technology for the snout bream is the first problem of realizing artificial breeding and increasing cultivation.
At present, researches on artificial breeding of the rhabdosarus transversely are mainly performed by natural spawning of parents, but the male proportion of the rhabdosarus transversely parent population is low, and the maturity of male and female parent fishes is different, so that the asynchronization of ovulation and semen excretion is caused. Generally, the male matures earlier than the female, which results in a low fertilization rate and a large number of unfertilized ova in the later stage of natural spawning due to the shortage of mature male fish. Meanwhile, the rhabdosargus sargassum belongs to a small number of spawning types which spawn repeatedly in batches, and excessive spawning batches bring much trouble to fry cultivation management. Meanwhile, after spawning is finished for the first time, because the management of the postpartum parent fish is not in place, if the parent fish does not obtain sufficient nutrition and proper environmental conditions, the subsequent spawning amount is obviously reduced, the quality of ova is reduced, and further the fertilization rate is reduced. The technical means of artificial induced spawning can well solve the problems of asynchronous maturation of male and female in the parent group of the porgy fasciatus, low male proportion and the like. There are reports on the research of "preliminary experiments of breeding, spawning and hatching of parent fish of snout bream": the parent fish cultured conventionally can naturally lay eggs by induced spawning; the egg laying amount and the hatching rate of the parent fish intensively cultured in the indoor cement pond are not as good as those of the parent fish intensively cultured by the net cage, but the parent fish cultured in the shrimp pond has low survival rate and bad gonad development and can not lay eggs by induced spawning. However, the document does not describe a method for distinguishing male and female parents, an optimal induction date, the type and dosage of an induction agent and induction effect time, and a method for nursing and managing after first spawning according to the characteristics of multiple spawning in batches. At present, no stable and efficient artificial spawning induction method for the bream with snout bream exists.

The horizontal snout porgy is cultured in a fish catching frame in the transfer device, the fish catching frame comprises a bottom plate, a top frame, a baffle plate and a blocking net, and the baffle plate and the blocking net are enclosed into a frame-shaped structure and are surrounded between the bottom plate and the top frame. When the water needs to be changed for the culture pond, the lifting device drives one side of the bottom plate, which is far away from the baffle, to move upwards, and as the bottom plate is hinged with the baffle, one side of the bottom plate gradually draws close towards the top frame and forms a triangular structure with the top frame and the baffle, and the horizontal porgy is concentrated at an included angle between the bottom plate and the baffle. And in the ascending process of the bottom plate, the bottom plate pushes the cam deflector rod upwards, and the cam deflector rod rotates to drive the flip cover to rotate and cover the fish pond. The cam deflector rod is in interference fit, and can also be turned over manually. The drive motor is started, the drive motor drives the rotating shaft to rotate, then the top frame is driven to rotate, one end, close to the baffle, of the bottom plate is upwards overturned to the bottom plate to be separated from the culture pond, the horizontal mustache is lifted and kept away from the culture pond, along with the continuous overturning of the bottom plate, one side, close to the baffle, of the bottom plate is higher than one side, far away from the baffle, the horizontal mustache slides into a new water pond along the bottom plate, and at the moment, sewage suction and water replacement can be carried out on the vacant culture pond. The new water pool is provided with a transfer device with the same structure, and after the water in the culture pool is changed, the snout breams in the new water pool can be transferred to the culture pool. When artificial hastening of the horizontal snout bream is needed, the horizontal snout bream is transferred from the culture pond to a new water pond, a bottom plate in the culture pond moves downwards to reset, the cam shifting lever is driven to rotate in the downward movement process, and then the flip is driven to rotate in the vertical direction and open the fish taking pond. When the horizontal snout bream is transferred by the transferring device in the new water pool, the horizontal snout bream can enter the fish taking pool one by one from the new water pool due to the opening of the fish taking pool, the horizontal snout bream in the fish taking pool is fished out one by one to carry out artificial induced spawning, and the culture pool can be simultaneously disinfected by changing water in the induced spawning process. When the horizontal snout breams slide along the bottom plate toward the new fish pool, the fish guiding grooves formed between the ribs on the bottom plate can guide the horizontal snout breams to sequence so that the horizontal snout breams enter the fish taking pool in order. The whole device is convenient for transferring the rhabdosarus punctatus, improves the transfer efficiency of the rhabdosarus punctatus, further improves the efficiency of water changing and sterilization, reduces the outbreak rate of the amylooococcosis, improves the survival rate, avoids the risk of cultivation, and most importantly, can transfer the rhabdosarus punctatus needing manual induced spawning one by one in the idle period of water changing to implement manual induced spawning.
