Problems solved by technology

[0004] How to make eels change their eating habits as soon as possible, from powder feeding to buoyant pellets is of great significance to eel farming. If the domestication effect is not good, the growth rate and economic benefits will be greatly affected if the domestication effect is not good.

Embodiment 1

[0019] Embodiment 1: Comparative experiment of juvenile eel domestication and feeding with floating pellets

[0020] Put 90,000 American eel juveniles with a size of 120 / kg into six intensive culture ponds with an area of ​​150 square meters, and put 15,000 in each pond. Randomly divide the six ponds into two groups, namely the powder group and the floating pellet group (feeding E00 series eel extruded compound feed), with three ponds in each group. After the eel seedlings entered the pond, they were fed powder and adapted to the routine for 14 days, and then the comparative test began. During the test period, the water quality and feeding management of the two groups were consistent. Among them, the powder group was still fed with the original powder, and the buoyant pellet group was tamed with the buoyant pellet feed according to the following steps.

[0021] Feed preparation: According to the nutritional requirements of 120 eels / kg, the floating pellet feed of American ee...

Embodiment 2

[0034] Embodiment 2: Comparative experiment of juvenile eel domestication and feeding with floating pellets

[0035] Put 60,000 tails of 30 juveniles / kg American eel juveniles into six intensive culture ponds with an area of ​​150 square meters, each with 10,000 tails. Randomly divide the six pools into two groups, namely the powder group and the buoyant granular material group, with three pools in each group. After the eel seedlings entered the pond, they were fed powder and adapted to the routine for 14 days, and then the comparative test began. The feeding and management of the two groups were the same during the experiment. Among them, the powder group was still fed with the original powder, and the buoyant pellet group was fed with buoyant pellets according to the following steps.

[0036] Feed preparation: According to the nutritional requirements of 30 eels / kg, the American eel floating pellet feed is made. The difference between the two is that the α-starch in the po...

Embodiment 3

[0048] Embodiment 3: Comparative experiment of adult eel taming and feeding with floating pellets

[0049] Put 60,000 tails of 12 / kg American eel adult eels into six earthen ponds with an area of ​​4 mu, each with 10,000 tails. Randomly divide the six pools into two groups, namely the powder group and the buoyant granular material group, with three pools in each group. After the eel seedlings entered the pond, they were fed powder and adapted to the routine for 14 days, and then the comparative test began. The feeding and management of the two groups were the same during the experiment. Among them, the powder group was still fed with the original powder, and the buoyant pellet group was fed with buoyant pellets according to the following steps.

[0050] Feed preparation: According to the nutritional requirements of 12 eels / kg, the American eel floating pellet feed is made. The difference between the two is that the α-starch in the powder is replaced by the same amount of ord...

Abstract

The invention discloses a domesticating method for feeding eels with floating pellet feed. The domesticating method comprises the following steps: stopping feeding at the first day; from the second tothe sixth day, performing feeding twice a day, according to the weight ratio of original powder feed to the floating pellet feed is (5-25):(75-95), taking the original powder feed, adding 3-5 times of water by weight and preparing suspension liquid, then putting the floating pellet feed into the suspension liquid and soaking the floating pellet feed for 1-3 minutes, then putting the feed into a feeding platform for eels to ingest, and gradually reducing the proportion of the original powder feed every day; and from the seventh day and after, performing feeding twice a day, soaking the floating pellet feed in clear water for 1-3 minutes, and after the feed absorbs some moisture and are softened and wetted, putting the feed into the feeding platform. The domesticating method can realize thorough domestication of the eels to ingest the floating pellet feed in 7-12 days, solves the problems of much remaining feed, unbalanced nutrients, high cost, easy deterioration of water quality, wasteof water sources, increase of labor and the like induced by ingestion of powder feed, is suitable for large-scale breeding of eels and is of great importance for intensive breeding and development ofthe eel industry.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to a method for taming eels by feeding buoyant pellets. Background technique [0002] Eel is a high-quality edible fish with high protein and high fat. It is delicious, nutritious, and has certain medicinal functions. It has been a precious nourishing food among Chinese people since ancient times. Efficacy, known as "water ginseng". Since my country fully introduced Japanese eel farming technology in 1979, eel farming has flourished; by the mid-1990s, the scale and output of eel farming in my country had surpassed that of Japan, ranking first in the world. , feed production, grilled eel and eel by-product processing, export trade and supporting services as one of the complete industrial chain. [0003] Traditional eel feeding uses powdered feed, that is, before each feeding, water needs to be added and a mixer is used to make dough, which is placed on the feeding table for eels...
