The purpose of Eel Breeding

Eel seedling domestication refers to the first-level pool cultivation of eel seedlings. Eel seedlings lurk in the natural environment and come out day and night to forage. The food is mainly fresh baits such as small fish, small shrimps, larvae of some aquatic insects, silkworms, swaying larvae, etc., with slow growth and low survival rate. Generally, it takes 5 to 6 years to grow into a commodity specification. Therefore, if you want to sell commercial eels from eel seedlings within 1 to 2 years, you must manually feed it. In order to change the feeding mode and food variety of eel seedlings and accelerate their growth, eel seedlings must be domesticated.

Domestication is the key to the success or failure of cultivating good eel species. It generally takes 3 weeks to domesticate eel seedlings, reaching 3 changes: 1 Change the night feeding to daytime feeding (due to the low dissolved oxygen in the water at night, weak feeding and digestion ability of eel, low feed efficiency, and inconvenient management); 2 Change to disperse foraging to collect e food (so that eel grows evenly, reduces the dispersion of feed, and facilitates fishing); 3 Change to fresh bait to feed with feed (with comprehensive nutrition, the bait group made contains less water than fresh bait, and the growth rate of eel seedlings is high, which is fast, which is conducive to large-scale production).

The induction bait for domesticated eel seedlings has the best induction effect of silkworms, but there are also oysters, clam meat, earthworms, etc. after pounding, the induction bait, and the effect is slightly worse. In recent years, the basic mode of eel seedling bait transition in eel farms in various places is: silkworms - (silk earthworm ten compound feed) - compound feed. The advantages of silkworms as bait in the early stage of eel seedlings are: 1 the smell has a strong attraction; 2 the nutrition is good; 3 the individual slender activity is slow, which is convenient for eel seedlings to prey; 4 the life force is strong, and the residual silk earthworm will not pollute the water quality, etc. ( This article is selected from "Supporting Technology for Eel Breeding")
