Embodiment 1

[0026] In an artificial small-volume crucian carp breeding pond with 60 cages / group in a research and development base, the cages (cage size 1×1×1.5) were fed. 100 crucian carp with an average weight of 28.75 g were raised in each box, and the sinking pellet feed with a particle size of Ф2.0 was fed. The feeding rate was 3%, and the feeding was divided into 4 times a day. Such as figure 1 As shown, the feeding method takes 4 cages as a unit, and feeds 3 rotations in a clockwise (or counterclockwise) direction. After feeding a unit, continue to feed the next unit (the next group of 4 cages). Feed until the whole group of test cages are fed, such as figure 2 shown. A new round of feeding was started, and a total of 5 rounds were fed, that is, the feeding method of 3 turns × 5 rounds, and the feeding took 30 minutes. After continuous feeding for 56 days, crucian carp was caught and weighed. The weight gain rate of crucian carp was 102%, and the bait coefficient was 1.90.

Embodiment 2

[0031] In an artificial small-volume grass carp breeding pond with 40 cages / group in a research and development base, the cages (cage size 1×1×1.5) were fed. 70 grass carp with an average weight of 168.50 g were raised in each box, and the pellet feed with a particle size of Ф3.5 was fed. The feeding rate was 4%, and the feeding was divided into three times a day. The way of feeding is to use horizontally adjacent 4 cages as a unit, in order from left to right, feed 4 rounds, after feeding one unit, continue to feed the next unit (the next group of 4 cages), Until the whole group of test cages were fed. A new round of feeding was started, and a total of 6 rounds were fed, that is, the feeding mode of 4 turns × 6 rounds, and the feeding took 22 minutes. After 56 days of continuous feeding, the grass carp was caught and weighed. The weight gain rate of grass carp was 188%, and the bait coefficient was 1.37.

Embodiment 3

[0036] In an artificial small-volume carp breeding pond with 30 cages / group in a research and development base, the cages (cage size 1×1×1.5) were fed. 70 grass carp with an average weight of 38.00 g were raised in each box, and the pellet feed with a particle size of Ф2.0 was fed. The feeding rate was 5%, and the feeding was divided into three times a day. The way of feeding is to use horizontally adjacent 4 cages as a unit, in order from left to right, feed 4 rounds, after feeding one unit, continue to feed the next unit (the next group of 4 cages), Until the whole group of test cages were fed. Started a new round of feeding, a total of 4 rounds of feeding, that is, 4 turns × 3 rounds of feeding, and feeding took 22 minutes. After continuous feeding for 56 days, carp were caught and weighed. The weight gain rate of carp was 318%, and the feed coefficient was 1.20.

Abstract

The invention discloses a manual net cage precipitable feed feeding method. The manual net cage precipitable feed feeding method comprises the following steps that (1) every four adjacent net cages are used a unit, and feeding is conducted for N turns in the clockwise direction or anticlockwise direction, wherein N is a natural number; (2) after feeding is conducted on one unit, feeding is conducted on the next unit in the same way, feeding is conducted repeatedly in the same way until feeding is conducted on test net cages of a whole group, and in this way, a feeding round is completed; (3) the step (1) and the step (2) are executed again until m feeding rounds are completed, wherein M is a natural number. According to the manual net cage precipitable feed feeding method, the N turns*M rounds feeding mode is adopted, during the N feeding turns, a time interval exists between every two turns, so that fish can swallow feed after gathering the feed, and it is avoided that the feed is dissolved in water and wasted due to the fact that the feed is not eaten by the fish in time; the feed can be evenly fed in a distributed mode through the M feeding rounds, a fish school can easily eat the feed in batches, waste of the feed is avoided, and the difference among the fish school is reduced.

Description

technical field [0001] The invention relates to aquaculture, in particular to a method for feeding artificial cage sedimentary feed. Background technique [0002] China is a big aquaculture country. In recent years, the aquaculture industry has developed rapidly, and the scale of aquaculture has continued to expand. Different types of aquatic organisms show different habits in the process of artificial breeding, and have different requirements for feed ingredients. The various properties of the feed are related to the quality of the aquatic organisms’ feeding, the amount of residual bait, the growth rate and the utilization rate of the feed. For different aquatic organisms, different feeds need to be formulated, even for the same fish in different feeding stages. Feed different feed formulations. Pellet compound feed is the main feed, because of its convenient transportation and relatively stable storage, its market share is mainstream. However, pellet feed also has certa...
