Single-barrel culture system for parent shrimps of penaeus monodon

Abstract

The invention discloses a single-barrel culture system for parent shrimps of penaeus monodon. The single-barrel culture system is implemented by the aid of a maturation promoting barrel, an inflation device, a water temperature regulating device and a water flow device. The inflation device, the water temperature regulating device and the water flow device are arranged in the maturation promoting barrel, a barrel bottom of the maturation promoting barrel is made of transparent materials, protruded convex lens structures are arranged on the outer surface of the barrel bottom, grooves are formed in the edge of the inner surface of the barrel bottom and are perforated through barrel walls of the maturation promoting barrel via at least one drain pipe, and a pipe orifice of a water inlet pipe of the water flow device is close to the inner surface of the barrel bottom. The single-barrel culture system has the advantages that the single-barrel culture system is convenient to implement, the parent shrimps can be conveniently managed, the water temperatures can be constant, disturbance and stimulation on the parent shrimps of the penaeus monodon due to frequent water change can be relieved, accordingly, the sex gland maturation time of the parent shrimps can be shortened, and the sex gland maturation rate of the parent shrimps can be increased; sex glands of each parent shrimp can be absolutely assuredly explored, illuminated and observed, and accordingly the single-barrel culture system is greatly beneficial to saving the labor cost and improving the work efficiency.

Description

technical field [0001] The invention relates to a single-tank cultivation technology of Penaeus monodon broodstock, specifically cultivating the broodstock of Penaeus monodon in a single bucket and hatching larvae in a single bucket, belonging to the technical field of aquaculture. Background technique [0002] In the prior art, when cultivating the broodstock of Penaeus monodon, the method of putting the whole batch of broodstock into the same cement pond for centralized management is usually adopted, that is, selecting healthy species of shrimp and using physical methods to cut off the unilateral eye stalk of the broodstock for the purpose of Remove the X organ in the eye stalk to accelerate the development of its gonads, and then put it into a special broodstock breeding pond for unified management. The operators control the water temperature of the broodstock pond every day, regularly cross-feed high-nutrient baits such as squid and clamworm, absorb sewage and change wat...

Problems solved by technology

[0003] This kind of group breeding uses boilers or solar energy to heat up, and the temperature needs to be monitored by humans from time to time, which not only causes a waste of manpower, but also easily causes excessive temperature due to human errors. High or too low will affect the maturation of broodstock gonads; if a large number of broodstock are kept in the same cement pond, a large amount of bait needs to be fed, which will bring a lot of residual bait and feces, so a large amount of broodstock ponds need to be cleaned every day. Changing the water, changing the water every day will stimulate the brood shrimp, and the brood shrimp will jump violently after being stimulated, which will affect the development of the gonads in light cases, and even lead to the death of the brood shrimp in severe cases; When the shrimp search device is used to search the gonads, it needs to walk back and forth in the brood shrimp pond, which is also easy to disturb the brood shrimp. And broodstock often swim back and forth, which requires the operator to repeatedly search for each shrimp, which not only increases the workload, but also very likely causes missed checks: that is, the broodstock with well-developed gonads has not been detected. According to the research, this will cause great economic losses to commercial seedling breeding, and cause a waste of family materials or group materials for scientific researchers
