Problems solved by technology

However, there are few soft-shelled turtle eggs on the market because soft-shelled turtle meat is a tonic with good health effects. In recent years, the number of soft-shelled turtles has been increasing year by year. , the number of farmers raising soft-shelled turtles is increasing, and the breeding scale of the original farmers is getting bigger and bigger. Most of the domestic soft-shelled turtle eggs are reserved for breeding, which still cannot meet the needs of soft-shelled turtle fry. Thailand and Vietnam import a large amount of soft-shelled turtle eggs or soft-shelled turtle fry

Embodiment 1

[0020] At the end of April each year, 2-3 year old soft-shelled turtles are selected from the turtle breeding ponds for meat. The ratio of female to male soft-shelled turtles is 4:1, and they are put into ponds specially used for laying eggs; Add 20g of quicklime per cubic meter of water. The pond is designed as flowing water. The flow of water entering the pond is 0.5 cubic meters per hour, and the flow of water flowing out of the pond is also 0.5 cubic meters. 10g of quicklime is added per hour; from early May to At the end of August, feed soft-shelled turtles tenebrio molitor and apple snails on the first day, fly maggots and fish meal on the second day, tenebrio molitor and fish meal on the third day, and apple snails and fly maggots on the fourth day. This feeding method is a cycle. Repeat feeding in this way; there is a place for basking in the pond, and the soft-shelled turtles are allowed to bask in the sun for 30 minutes every day. If it is rainy, an incandescent lamp ...

Embodiment 2

[0022] At the end of April every year, 2-3 year old soft-shelled turtles are selected from the meat turtle breeding ponds. The ratio of female to male soft-shelled turtles is 5:1, and they are put into ponds specially used for laying eggs; Add 25g of quicklime per cubic meter of water. The pond is designed as flowing water. The flow of water entering the pond is 0.8 cubic meters per hour, and the flow of water flowing out of the pond is also 0.8 cubic meters. 20g of quicklime is added per hour; from early May to At the end of August, feed soft-shelled turtles tenebrio molitor and apple snails on the first day, fly maggots and fish meal on the second day, tenebrio molitor and fish meal on the third day, and apple snails and fly maggots on the fourth day. This feeding method is a cycle. Repeat feeding in this way; there is a place for basking in the pond, and the soft-shelled turtles are allowed to bask in the sun for 45 minutes every day. If it encounters rainy days, an incandes...

Embodiment 3

[0024] At the end of April every year, 2-3 year old soft-shelled turtles are selected from the meat turtle breeding ponds. The ratio of female to male soft-shelled turtles is 6:1, and they are put into ponds specially used for laying eggs; Add 30g of quicklime per cubic meter of water. The pond is designed as flowing water. The flow of water entering the pond is 1 cubic meter per hour, and the flow of water flowing out of the pond is also 1 cubic meter. 30g of quicklime is added per hour; from the beginning of May to At the end of August, feed soft-shelled turtles tenebrio molitor and apple snails on the first day, fly maggots and fish meal on the second day, tenebrio molitor and fish meal on the third day, and apple snails and fly maggots on the fourth day. This feeding method is a cycle. Repeat feeding in this way; there is a place for basking in the pond, and the soft-shelled turtles are allowed to bask in the sun for 60 minutes every day. If it encounters rainy days, use an...

Abstract

The invention provides a method for improving yellow sand trionyx sinensis egg production. The method for improving the yellow sand trionyx sinensis egg production is characterized in that parent trionyx sinensises at the age of 2-3 are selected according to a ratio of 4-6:1 of mother trionyx sinensises to father trionyx sinensises, and are placed into a pond special for being used for egg laying. 20-30g calcined lime is placed in each cube water in the pond, and the pond is designed to be filled with flowing water. From May to the end of August, a feeding method that a breeder feeds flour weevils and ampullaria gigas to soft-shelled trionyx sinensises in a first day, the breeder feeds fly maggots and fish meals to the soft-shelled trionyx sinensises in a second day, the breeder feeds the flour weevils and the fish meals to the soft-shelled trionyx sinensises in a third day, and the breeder feeds the ampullaria gigas and the fly maggots to the soft-shelled trionyx sinensises is regarded as a cycle to feed the soft-shelled trionyx sinensises repeatedly. A place for the soft-shelled trionyx sinensises to bask is arranged in the pond. The soft-shelled trionyx sinensises are enabled to bask for 30-60minutes per day, filament lamps are used as light sources in rainy days, and the filament lamps are turned on for 1-5h every night. The purpose of turning on the lamps is to attract insects at night, and if the soft-shelled trionyx sinensises see the insects, the soft-shelled trionyx sinensises can get out of water to prey on the insects naturally. Under the lamplight, the soft-shelled trionyx sinensises can absorb luminous energy to promote absorption of calcium. The egg production of the yellow sand trionyx sinensis is improved by 20-30% through the breeding method.

Description

technical field [0001] The invention relates to a method for increasing egg production of yellow sand soft-shelled turtle, which belongs to the technical field of freshwater culture. Background technique [0002] Soft-shelled turtle, Latin scientific name Trionyx sinensis, commonly known as soft-shelled turtle, water fish, turtle and tomba, etc., is an egg-laying reptile that lives amphibiously on land and water. The yellow sand soft-shelled soft-shelled soft-shelled soft-shelled soft-shelled soft-shelled soft-shelled soft-shelled soft-shelled soft-shelled soft-shelled soft-shelled soft-shelled soft-shelled soft-shelled soft-shelled soft-shelled soft-shelled soft-shelled soft-shelled soft-shelled soft-shelled soft-shelled soft-shelled soft-shelled soft-shelled soft-shelled soft-shelled soft-shelled soft-shelled soft-shelled soft-shell soft-shelled soft-shelled soft-shell soft-shelled soft-shell soft-shelled soft-shell soft-shelled soft-shell soft-shelled soft-shell soft-shell...
