Method and device for breeding rana nigromaculata in rice field in segmented purse seine manner

Abstract

The invention relates to the technical field of frog breeding, in particular to a method and device for breeding rana nigromaculata in a rice field in a segmented purse seine manner. Small breeding areas are formed by arranging segmented purse seines; when rana nigromaculata froglets are thrown, the rana nigromaculata froglets are thrown into the small breeding areas; the rana nigromaculata froglets have relatively small sizes, and on the basis of the same number of the put rana nigromaculata, the culture space required by the rana nigromaculata froglets is relatively small, so that the swimming space of the rana nigromaculata froglets is reduced, the swimming distance of the rana nigromaculata froglets can ensure the memory of the rana nigromaculata froglets on feeding tables; the froglets can return to the feeding tables in time to find food, so that the mortality rate of froglets of rana nigromaculata died due to hunger is greatly reduced; and the putting survival rate of the rana nigromaculata froglets is increased, the supplementing amount of the froglets is reduced, the breeding cost is reduced, and the economic benefits are improved.

Description

technical field [0001] The invention relates to the technical field of frog breeding, in particular to a method for cultivating black-spotted frogs with segmented nets in paddy fields and a device for cultivating black-spotted frogs. Background technique [0002] Black-spotted frogs are common frogs, belonging to Ranaidae, Anura, and amphibians. The black-spotted frog has tender meat, less fat, low sugar, and high protein content. It has the effects of clearing away heat and detoxification, reducing swelling and relieving pain. The artificial breeding of black-spotted frog not only has simple technical requirements, but also has fast economic results. Therefore, black-spotted frog breeding has become a focus of attention in aquaculture. [0003] At present, black-spotted frog breeding often uses natural ponds or artificially built ponds to raise them at high density to achieve intensive farming. However, this intensive breeding not only takes up a lot of land resources, bu...

AI Technical Summary

Problems solved by technology

[0004] It can be seen that in the prior art, the paddy field is enclosed in the center of the breeding pond, and a breeding ditch is opened in the paddy field to form a black-spotted frog breeding pond, and then the black-spotted frog tadpoles or black-spotted frog young frogs are put in the breeding pond Medium breeding, put food on the feeding platform for the black-spotted frog to forage, so as to realize the polyculture of rice and black-spotted frog, achieve the purpose of imitating wild black-spotted frog breeding, and improve the meat quality and taste of the black-spotted frog. Realize the green and pollution-free planting of rice; but in the prior art, when the black-spotted frog is put in the breeding pond, because the black-spotted frog seedlings or black-spotted frog tadpoles are constantly swimming in the breeding pond, they are gradually far away from the breeding pond. The food table, resulting in some black-spotted frog seedlings or black-spotted frog tadpoles swimming out, with a large area, making it impossible to swim back to the feeding table in time, causing the young black-spotted frog frogs to forget the location of the feeding table, resulting in long-term inaccessibility. The food supply caused the young black-spotted frogs to be starved to death in the early stage, so that it is necessary to continuously replenish the young black-spotted frogs to meet the needs of the breeding density in the breeding area, resulting in high breeding costs, otherwise it will lead to poor utilization of rice fields. Low, the output of the black-spotted frog per unit area of ​​the breeding pond is low, and the economic benefit is poor
