Description

Technical Field

[0001] The invention belongs to the technical field of fish breeding, and in particular relates to a feeding training method for mandarin fish fry. Background Art

[0002] Mandarin fish is a freshwater fish with tender meat and delicious taste. It has certain medicinal and economic value, large market demand and broad breeding prospects.

[0003] At present, mandarin fish are generally fed with live bait fish during farming. This farming method not only requires the equipment of live bait fish breeding ponds, which is costly, but also the live bait fish are easy to bring in pathogens, resulting in a decrease in mandarin fish farming yields. In order to solve the above problems, mandarin fish farming is developing from feeding live bait fish to domesticating mandarin fish to eat artificial feed.

[0004] Chinese Patent No. 201711061587.7 discloses a method for feeding mandarin fish fry, and specifically discloses the following contents: selecting mandarin fish fry with the same body length and weight as the feeding objects; placing the selected mandarin fish fry into the training pond for adaptation and then conducting cluster training for three days, that is, at 6:00 in the morning and 18:00 in the evening every day, using lights and dripping water to lure the mandarin fish fry to the training area of ​​the training pond, each time for 4-6 minutes, and then starting to feed fresh live bait fish; after the cluster training is completed, the mandarin fish fry are trained to eat ice-fresh bait fish, and during the feed transfer process, 10-50% of the satiety amount of the mandarin fish fry is continued to be fed during each feeding of ice-fresh bait fish. fresh bait fish, and after the mandarin fish fry have adapted to the chilled bait fish, only chilled bait fish are fed; the mandarin fish fry that have been acclimated to the chilled bait fish are acclimated to the soft pellet feed, and during the feed change process, 10-73% of the mandarin fish fry's satiation amount of chilled bait fish continues to be fed during each soft pellet feed feeding, and after the mandarin fish fry have adapted to the soft pellet feed, only soft pellet feed is fed; the mandarin fish fry that have been acclimated to the soft pellet feed are acclimated to the hard pellet feed, and during the feed change process, 10-82% of the mandarin fish fry's satiation amount of soft pellet feed continues to be fed during each hard pellet feed feeding, and after the mandarin fish fry have adapted to the hard pellet feed, only hard pellet feed is fed.

[0005] The inventors of the present application discovered that the above-mentioned feeding training method for mandarin fish fry did not carry out feeding training in different areas for the mandarin fish fry, resulting in all the mandarin fish fry swimming to the feeding training area to feed during feeding training, which may cause some mandarin fish fry to eat too much and some mandarin fish fry to eat too little, thereby reducing the survival rate of the mandarin fish fry after feeding training. Summary of the invention

[0006] To solve the problems raised in the above background technology. The present invention provides a feeding training method for mandarin fish fry, which can train mandarin fish to feed in different areas, solve the problem in the prior art that the survival rate of mandarin fish fry is reduced due to some mandarin fish fry eating too much and some mandarin fish fry eating too little. At the same time, the artificial bait during feeding training still realizes the simulated activity function of live bait through the external structure, so that mandarin fish fry can accept artificial bait faster, thereby improving the feeding training effect of mandarin fish fry.

[0007] To achieve the above object, the present invention provides the following technical solution: a method for feeding mandarin fish fry, comprising the following steps:

[0008] S1: Construct a total cluster domestication pond for mandarin fish fry;

[0009] S2: Divide the area of ​​the total cluster training pond of mandarin fish fry into multiple cluster training feeding areas for mandarin fish fry;

[0010] S3: Calculate the number of mandarin fish fry that can be accommodated based on the divided areas of multiple mandarin fish fry grouping training feeding areas;

[0011] S4: Select the same number and area of ​​culture containers as those in the divided multiple feeding training areas for mandarin fish fry;

[0012] S5: flushing pipes are respectively arranged at the horizontal plane positions of the plurality of breeding containers, the water inlet ends of the flushing pipes are connected to a water pump, the water inlet ends of the water pumps are connected to the bottoms of the corresponding breeding containers, and then the plurality of breeding containers are respectively disinfected and filled with water;

[0013] S6: placing the same number of mandarin fish fry as the calculated number of mandarin fish fry that can be accommodated into a plurality of breeding containers respectively;

[0014] S7: When feeding, start the water pump, the water pump pumps the water in the breeding container to the flushing pipe, and the flushing pipe returns the water to the breeding container. In this process, the water flow impacts the horizontal surface of the breeding container to cause fluctuations, so as to train the feeding signal of the mandarin fish fry. Before adaptation, put live baits of suitable proportions, and after adaptation, put live baits of different colors of suitable proportions to train the feeding response of the mandarin fish fry to live baits of different colors;

[0015] S8: a partition with a through hole is respectively arranged near the wall side of the multiple mandarin fish fry sub-cluster training and feeding areas of the mandarin fish fry total cluster training and breeding pond, through which bait can pass but mandarin fish fry cannot pass; at the same time, a drum cart is rotatably arranged above the partition in the multiple mandarin fish fry sub-cluster training and feeding areas of the mandarin fish fry total cluster training and breeding pond, the feeding end of the drum cart is located on the side of the partition close to the wall, the discharging end of the drum cart is located on the side of the partition away from the wall, the driving end of the drum cart is connected to the motor, and a through hole is arranged on the drum cart plate, through which bait cannot pass; at the same time, a feeding pipe is respectively arranged at the feeding end of the drum cart in the multiple mandarin fish fry sub-cluster training and feeding areas of the mandarin fish fry total cluster training and breeding pond, the feeding end of the feeding pipe is connected to a feed pump, and the water inlet end of the feed pump is connected to the bottom of the corresponding mandarin fish fry sub-cluster training and feeding area, and at the same time, the mandarin fish fry total cluster training and breeding pond is disinfected and watered;

[0016] S9: releasing the mandarin fish fry that have been trained with feeding signals and live baits of different colors into the mandarin fish fry total cluster training pond;

[0017] S10: When feeding, start the feed pump, which pumps the water in the mandarin fish fry total cluster training pool to the feed pipe. The water in the feed pipe impacts the drum car plate of the drum car, and most of the water falls through the through holes of the drum car plate to the space between the partition and the side close to the zone wall, and then flows back through the through holes of the partition to the space between the partition and the side far from the zone wall. A small part of the water drops on the horizontal plane of the space between the partition and the side far from the zone wall as the drum car plate rotates, causing horizontal plane fluctuations. The mandarin fish fry trained with feeding signals swim to the water surface to feed. Before adaptation, live baits of different colors in suitable proportions are put in. After adaptation, live baits and artificial baits of different colors and different proportions are put in time periods until all artificial baits of different colors are put in and the training is stopped. The feeding reaction of mandarin fish fry to baits of different colors is completed.

[0022] Furthermore, in step S7, the method for preparing live bait specifically includes:

[0023] S71: Purchase healthy, disease-free crucian carp, whitebait and shrimp;

[0024] S72: Clean the purchased crucian carp, wheatear fish and shrimp;

[0029] S76: Soaking the live baits prepared in step S73 in solutions of different colors respectively;

[0030] S77: Take out the soaked live bait, rinse it gently with clean water to remove excess pigment on the surface, and press it gently with a sponge to remove excess water on the surface, which will be live bait of different colors.

[0031] Furthermore, in step S10, a small amount of water drips onto the horizontal plane of the partition and the space away from the side of the zone wall as the drum car plate rotates, causing the horizontal plane fluctuation to be the same as the horizontal plane fluctuation caused by the impact of the water flow flushed out of the flushing pipe in step S7.

[0032] Furthermore, in step S10, the adaptation ratio before adaptation is 1.5%-2%, and the adaptation ratio after adaptation is 0.5%-1.5%. At the same time, from the first to the fifth day after adaptation, the ratio of live bait and artificial bait is 4:1, from the sixth to the ninth day after adaptation, the ratio of live bait and artificial bait is 3:2, from the tenth to the twelfth day after adaptation, the ratio of live bait and artificial bait is 2:3, from the thirteenth to the fourteenth day after adaptation, the ratio of live bait and artificial bait is 1:4, and on the fifteenth day after adaptation, the ratio of live bait and artificial bait is 0:5.
