Abstract
The invention belongs to the technical field of cultivation and particularly relates to a fry breeding method of sea eels. By the aid of the method, fry breeding of the sea eels is carried out, and oxygen partial pressure in a water body is improved to provide sufficient oxygen to sea eel fries; a micro-ecological preparation is added and foam of the water body is separated, so that the content of ammonia nitrogen, nitrite and organic matters in the water body is reduced; the water quality is controlled and a safe water body environment is provided for the fries; antibiotics are added periodically so that the occurrence rate of plant diseases and insect pests is obviously reduced and the survival rate of the fries is improved and is up to be more than 60%; the fry breeding method has a wide application prospect.
Description
Technical field
The invention belongs to cultivation seedling growing process field, specifically relate to the seedling-cultivating method of a kind of eel.
Background technology
Eel is rich in multiple nutritional components, and having the effects such as qi-restoratives nourishes blood, clearing damp, anti-consumptive disease, is the good nutrition product of the patients such as prolonged illness, weakness, anaemia, pulmonary tuberculosis.Its liver contains abundant vitamin A, is the excellent food of yctalopia people.It is also rich in vitamin A and vitamin E, and content is 60 times and 9 times of common fish respectively.Its vertebrae has almost possessed all needed for perfect calcium source, thus by domestic and international scientist is worshipped, is acknowledged as " desirable natural biological calcium source ", " the natural provider that the mankind are calcareous ".
But natural eel resource can not meet the consumption demand of the mankind far away, and therefore the aquaculture of eel also enters large-scale industrial production.The general hatchability of existing seedling-cultivating method is low, and easy infection enteron aisle disease.Therefore how improving breeding efficiency is technical barrier urgently to be resolved hurrily.
Summary of the invention
In order to overcome above-mentioned difficulties, the invention provides the seedling-cultivating method of a kind of eel, effectively improve the survival rate of nursery.
The invention design of this programme comprises the following steps:
1) water in nursery pond is in advance through foam separator process;
2) after nursery is hatched, about 25 DEG C cultivations;
3) cultivate feed of later throwing something and feeding for three days, throw something and feed every day 1 time, within every two days, change a water, after changing water, drop into probiotics particle at every turn;
4) cultivate feed of later throwing something and feeding for ten days, throw something and feed every day 2 times, within every two days, change a water, after changing water, drop into probiotics particle at every turn;
5) cultivate feed of later throwing something and feeding for 30 days to double, throw something and feed every day 2 times, within every two days, change a water, after changing water, drop into probiotics particle at every turn.
Oxygenous for ensureing nursery Shuifu County, foam fraction factor to be carried out through foam separator to water body in advance, be mainly used for separation of organic substances and colloid.During nursery, 12 hours nights threw in oxygenating rod at the bottom of pond.Thus provide sufficient oxygen for eel seedling.
In order to ensure the quality safety of water quality between nursery stage, effectively controlling the generation of ammonia nitrogen, nitrite etc., adding probiotics, described probiotics particle is based on bacillus subtilis, bacterial digestion.
Strict prophylactic infringement, added an antibiotic every 15 days between nursery stage in feed, described antibiotic is streptomycin or cephalo.
Beneficial effect of the present invention: carry out eel nursery by this method, improve partial pressure of oxygen in water body, for eel seedling provides sufficient oxygen, the interpolation of probiotics and the separation of water body foam, reduce the content of ammonia nitrogen and nitrite in water body, control water quality, for seedling provides safe water body environment, and by interim antibiotic interpolation, significantly reduce the incidence of damage by disease and insect, improve seedling percent, reach more than 60%, this seedling-cultivating method is with a wide range of applications.
Embodiment
Below in conjunction with the embodiment of the present invention, carry out clear and detailed description to the technical scheme in the embodiment of the present invention, obviously, described embodiment is only a part of embodiment of the present invention, instead of whole embodiment.Based on the embodiment in the present invention, those of ordinary skill in the art, not making other embodiments all obtained under creative work prerequisite, belong to the scope of protection of the invention.
A seedling-cultivating method for eel, comprises the following steps:
1) water in nursery pond is in advance through foam separator process;
2) after nursery is hatched, about 25 DEG C cultivations;
3) cultivate feed of later throwing something and feeding for three days, throw something and feed every day 1 time, within every two days, change a water, after changing water, drop into probiotics particle at every turn;
4) cultivate feed of later throwing something and feeding for ten days, throw something and feed every day 2 times, within every two days, change a water, after changing water, drop into probiotics particle at every turn;
5) cultivate feed of later throwing something and feeding for 30 days to double, throw something and feed every day 2 times, within every two days, change a water, after changing water, drop into probiotics particle at every turn.
Described foam separator is the device of a kind of effective separation of organic substances and colloid, prevent from again forming foam in seedling raising process, the accumulation of the formation of foam mainly organic substance, and the damage by disease and insect that exists for of organic substance provides hotbed, and the existence of foam also can have influence on the solvability of oxygen in water body.
Described probiotics particle, based on bacillus subtilis, bacterial digestion, is mainly used for the content reducing ammonia nitrogen and nitrite in water body, thus prevents amine substance to the murder by poisoning of seedling.
12 hours nights threw in oxygenating rod at the bottom of pond, and being of value at night is strengthen partial pressure of oxygen in breeding water body.
Every 15 days, add an antibiotic in feed, described antibiotic is streptomycin or cephalo, reduces harmful microbe breeding in water, the especially murder by poisoning of harmful microorganism many seedling intestinal tract.
In this specification, each embodiment adopts the mode of going forward one by one to describe, and what each embodiment stressed is the difference with other embodiments, between each embodiment identical similar portion mutually see.
To the above-mentioned explanation of the disclosed embodiments, professional and technical personnel in the field are realized or uses the present invention.Be apparent for those skilled in the art to the multiple amendment of these embodiments, General Principle as defined herein can without departing from the spirit or scope of the present invention, realize in other embodiments.Therefore, the present invention can not be restricted to these embodiments shown in this article, but will meet the widest scope consistent with principle disclosed herein and features of novelty.
