A kind of bream artificial cultivating method
Technical field
The present invention relates to aquaculture field, particularly relate to a kind of bream artificial cultivating method.
Background technology
China is the first in the world aquaculture big country, is also that unique aquaculture production exceedes and fishes in the world
The country of yield, aquaculture product yield accounts for the world 70%, and aquaculture occupies quite in national economy
Consequence.In recent years, China's aquaculture cause fast development, the cultivation of fresh water industry is as yield
Big aquaculture model annual average rate of increase is stably held in the fair speed of about 10%.Within 2008, China is light
Aquatic products production reaches 2297.3 ten thousand tons, and wherein freshwater aquiculture yield is 2072.5 ten thousand tons, accounts for China
The 90% of freshwater product production, and natural fishery production is only 224.8 ten thousand tons, account for about 10% (in
State's statistical yearbook, 2009).Fish-water Fish Farming is as yield maximum in freshwater aquiculture or even aquaculture
Part has had the history of more than 3000 year in China.Pushing away along with fish mixed feed over nearly 30 years
Wide and use, Fish-water Fish Farming industry has obtained the development advanced by leaps and bounds, has thus driven feed manufacturing machine work
Industry, the rapid progress of a series of related industries such as feed process industry.But, some traditional cultivation fishes
Class (such as grass carp, carp, bream, bream, bream etc.) constantly increases due to cultured output and consumes
Universal, along with gliding occurs in its price of development of market economy, cause culturist's profit to decline, cultivation heat
Feelings baffle.And during Fish-water Fish Farming, feed cost accounts for the 60-70% of totle drilling cost, along with fish
The drop of valency, the price of feed also goes way down.In recent years, due to vegetable protein and some are low in feed
The use of value raw material, attractant and the growth of some cultured fishes are a greater impact, and cause food ration to subtract
Less, poor growth, the death rate is higher, does not reaches commercial specification, further shadow within the normal culture-cycle
Having rung cultivation profit, this kind of situation seriously hinders freshwater fish culturing industry and manufacturing further of feed
Exhibition.
Summary of the invention
The technical problem to be solved is to overcome the defect of prior art, it is further proposed that a kind of
Bream artificial cultivating method.
The technical problem to be solved realizes by the following technical solutions.
A kind of bream artificial cultivating method, it is characterised in that comprise the following steps:
A. before fry is put in a suitable place to breed, is cleaned up the pond in fishpond and disinfect;
B. to fishpond water filling;
C. water filling bred fish fry after one week, and bream is raised together with a small amount of crucian, grass carp, bream and crucian, grass
Fish raise together with mantissa than for 6:1:1;
D. shrimp and spiral shell are put in a suitable place to breed in fishpond;
E. fry is thrown something and fed the mixed fodder that protein content is 32%~34%;
F. water quality is regulated and controled according to fishpond water quality situation according to the amount quick lime of every mu 10~20kg;
G. in fishpond, fresh water is periodically supplemented, it is ensured that effective water level in fishpond;
In described mixed fodder, mixture has additive, and additive is prepared from by the raw material of following weight portion:
Amomum powder 4 parts, dried orange peel 3 parts, 5 parts of cassia bark, peach blossom essential oil 2 parts, polished rice ash 6 parts, ground coffee 7 parts, big
Allicin 5 parts, lysine 10 parts, glycine 3 parts, sodium glutamate 2 parts, glycine betaine 5 parts, lotus nut starch 10 parts,
6 parts of river snail powder;
The each raw material preparing additive adds in mixer one by one, often adds a kind of raw material and is all sufficiently stirred for,
Make material after mixing, add another kind of raw material, after all materials all add and stir, to obtain final product
Feed addictive;
Described peach blossom essential oil is with peach blossom as raw material, the essential oil produced;
Producing of polished rice ash: polished rice is cooked ripe rice, then rolls into a ball into rice dumpling, place in fire and burn, will
Rice dumpling incinerates completely, obtains polished rice ash.
Described peach blossom essential oil uses supercritical carbon dioxide extraction method to prepare.
The invention have the benefit that
The bream artificial cultivating method that the present invention provides, added with additive in mixed feed, has food calling and promotees
The effect of growth, additive raw material steady sources, bream can be met to the sense of smell of mixed feed and the sense of taste
Requirement, hence it is evident that accelerate Feeding Velocity and improve food ration;The active ingredient of this feed addictive and proportioning warp
Inventor reaches to optimize in long-term experiment, is remarkably improved the resisting stress of bream while strengthening attractant
Ability and the speed of growth, reduce feed coefficient simultaneously;This feed addictive Long-Time Service is safe and efficient, nothing
Toxic and side effect.
Detailed description of the invention
For the technological means making the present invention realize, creation characteristic, reach purpose and effect and be readily apparent from
Solve, below in conjunction with specific embodiment, the present invention is expanded on further.
Embodiment 1
A kind of bream artificial cultivating method, comprises the following steps:
A. before fry is put in a suitable place to breed, is cleaned up the pond in fishpond and disinfect;
B. to fishpond water filling;
C. water filling bred fish fry after one week, and bream is raised together with a small amount of crucian, grass carp, bream and crucian, grass
Fish raise together with mantissa than for 6:1:1;
D. shrimp and spiral shell are put in a suitable place to breed in fishpond;
E. fry is thrown something and fed the mixed fodder that protein content is 32%~34%;
F. water quality is regulated and controled according to fishpond water quality situation according to the amount quick lime of every mu 10~20kg;
G. in fishpond, fresh water is periodically supplemented, it is ensured that effective water level in fishpond;
In mixed fodder, mixture has additive, and additive is prepared from by the raw material of following weight portion: fructus amomi
4 parts of powder, dried orange peel 3 parts, 5 parts of cassia bark, peach blossom essential oil 2 parts, polished rice ash 6 parts, ground coffee 7 parts, allicin 5
Part, lysine 10 parts, glycine 3 parts, sodium glutamate 2 parts, glycine betaine 5 parts, lotus nut starch 10 parts, river snail
6 parts of powder;
