Problems solved by technology

Excessive feeding will not only cause waste of feed and increase the cost of breeding, but also the residual bait will increase the load on the water body, deteriorate the bottom of the pond, and lead to the occurrence of giant river prawn diseases; rate drop
In short, too much or too little feed will seriously affect the breeding effect of Macrobrachium rosenbergii
[0003] However, at present, the methods for determining the suitable feeding amount in the culture process of Macrobrachium rosenbergii mainly include: 1. Place the feeding table, and regularly check the amount of feed in the feeding table to determine. The disadvantage is that the feeding table has a single location and cannot represent the entire pond. and if there are omnivorous fish in the water body, the feed in the feeding table will affect the judgment of the breeder; 2. Rely on rich experience to judge, experienced farmers will base The amount of feeding is determined by the size of the individual shrimp, and the effect is also good, but it is not easy for farmers who have entered the industry for a short time

Embodiment 1

[0031] A high-efficiency inspection process for Macrobrachium rosenbergii pond culture, including the production of a feeder and the steps of using the checker to check the material. The parameters of the search are set as follows:

[0032] The feeding time is 2 hours after each feeding, and 10 points are randomly selected along the four sides of the pond, and the four corners of the pond must be checked, and the interval between adjacent checking points is 20m; generally, the pond culture of giant giant rosenbergii is fed twice a day. Times, the morning feeding time is from 6:00 to 8:00, and the afternoon feeding time is from 17:00 to 18:00. The feeding amount in the morning is 30% to 40% of the feed amount for the whole day, and the feeding amount in the afternoon is 60% to 70% of the feed amount for the whole day.

[0033] When inspecting materials: the inspection hopper faces down into the water and touches the bottom of the pond, slowly drags the inspection hopper to the ...

Embodiment 2

[0042] A high-efficiency inspection process for Macrobrachium rosenbergii pond culture, including the production of a feeder and the steps of using the checker to check the material. The parameters of the search are set as follows:

[0043] The material checking time is 3 hours after each feeding. The material checking points are randomly selected from 20 points around the pond. The four corners of the pond must be checked, and the interval between adjacent material checking points is 5m.

[0044] When inspecting materials: the inspection hopper faces down into the water and touches the bottom of the pond, slowly drags the inspection hopper to the shore along the bottom of the pond at a uniform speed, cleans the mud in the inspection hopper, slowly moves the inspection hopper downward along the water surface, observes and records the collection The number of feed pellets received.

[0045]If it is found that the number of feed particles is greater than 30 grains / time, reduce t...

Embodiment 3

[0050] A high-efficiency inspection process for Macrobrachium rosenbergii pond culture, including the production of a feeder and the steps of using the checker to check the material. The parameters of the search are set as follows:

[0051] The material checking time is 3 hours after each feeding. The material checking points are randomly selected from 15 points around the pond. The four corners of the pond must be checked, and the interval between adjacent material checking points is 10m.

[0052] When inspecting materials: the inspection hopper faces down into the water and touches the bottom of the pond, slowly drags the inspection hopper to the shore along the bottom of the pond at a uniform speed, cleans the mud in the inspection hopper, slowly moves the inspection hopper downward along the water surface, observes and records the collection The number of feed pellets received.

Abstract

The invention discloses an efficient material checking technology for giant freshwater prawn pond culture. The technology comprises the steps of manufacturing a material checker and using the materialcheck for checking materials. The material checker is easy to manufacture, low in cost and capable of being manufactured by a farmer; the using method of the material checker is simple and convenientfor a pond opening to use; the material checking technology is simple and convenient to implement and high in practicability and universality; the material checking technology accurately judges the ingestion condition of giant freshwater prawn, the phenomena of insufficient feed and remaining feed are avoided, the feed utilization efficiency is improved, and therefore healthy and rapid growth ofgiant freshwater prawn is promoted, culture benefits of the farmer are increased, and ecological benefits of the culture environment are increased.

Description

technical field [0001] The invention relates to the technical field of Macrobrachium rosenbergii culture, in particular to a high-efficiency feed checking process for pond culture of Macrobrachium rosenbergii. Background technique [0002] Macrobrachium rosenbergii (Macrobrachium rosenbergii), also known as Malaysian prawn, is an omnivorous and bottom-foraging animal. It has the advantages of large size, rapid growth, and strong disease resistance. It has become an important economic shrimp in aquaculture in my country. one. The main breeding mode of Macrobrachium rosenbergii in China is pond culture, which has a large demand for feed and is not resistant to hunger, which puts forward strict requirements for the determination of the appropriate feeding amount. Excessive feeding will not only cause waste of feed and increase the cost of breeding, but also the residual bait will increase the load on the water body, deteriorate the bottom of the pond, and lead to the occurrence...
