Technical field
The invention belongs to fish culture field, be specifically related to a kind of method being improved carp culture production efficiency by hunger-compensatory growth aquaculture model.
Background technology
In the fish culture of reality is produced, the ratio that reduction feed cost occupies, improvement feeding pattern are the important channels of improving carp culture efficiency.After compensatory growth refers to animal via growth inhibition after a while, there is the phenomenon of Acceleration of growth when recovering favourable growth conditions.Relevant fish compensatory growth experimental studies have found that, after refeeding, larva starvation group body weight can be increased to or partly be increased to the body weight even exceeding the fish of normally throwing something and feeding continuously.The compensatory growth of different fish shows different compensation features, even same also has the difference showing complementary characteristics at different vegetative stages.Up to now, the compensatory growth research of nearly 70 kinds of fish such as existing salmon section, Cyprinidae, gadidae, Pangasiidae, Callichthyidae, Channel-catfish section, Puffer section, Bothidae, Chang section, clupeidae, Acipenseridae, and achieve the achievement of many stages.Wherein carp is partial-compensation, and the application that the mode of its compensation experiment, growth compensate and mechanism etc. thereof are not made clear.Wherein, hungry growth compensation ability and starvation time, to reply arranging of growth time closely related, and the what is more important this compensatory growth cycle is the very key factor affecting compensatory growth effect.Therefore, herein by what utilize the hungry different mode that recovers again to feed, the method obtaining and effectively improve carp culture efficiency is set, thus take different strategies of throwing something and feeding, reduction production cost, saving labour according to actual needs, the economic benefit of carp culture is provided.
Summary of the invention
The object of the invention is the problem for aquaculture model in carp culture, Demonstration And Extension process, provide a kind of method being improved carp culture production efficiency by hunger-compensatory growth aquaculture model, is the cultural method of a kind of practicable, easy to learn, easy popularization.
Improved a method for carp culture production efficiency by hunger-compensatory growth aquaculture model, in carp culture, adopt hunger-compensatory growth cultivation, hungry 5 ~ 15 days, then throw something and feed 20 ~ 60 days, repeat 1 ~ 3 cycle.
Adopt hunger-compensatory growth cultivation, preferably hungry 5 days, compensatory growth in 20 days of then throwing something and feeding, repeated 3 cycles, amounted to 75 days.
Adopt hunger-compensatory growth cultivation, preferably hungry 7 days, compensatory growth in 28 days of then throwing something and feeding, more hungry 7 days, compensatory growth in 34 days of then throwing something and feeding, amounts to 76 days.
Adopt hunger-compensatory growth cultivation, preferably hungry 15 days, compensatory growth in 60 days of then throwing something and feeding, amounts to 75 days.
Throw something and feed the stage according to every day three times manually the mode of throwing something and feeding feed.

Beneficial effect:
Use this aquaculture model, can between this culture zone in 75 days, realize growth rate and routine every day and to feed the same feeding effect, and number of days of feeding can shorten 15 days, namely 20%, feed saving rate is 7.3%(3 the mean value processed).This kind of method also can be applicable to other cultured fishes, also can be used for supporting temporarily in market sale process.
Accompanying drawing explanation
Fig. 1 is that different hunger-compensatory growth pattern is on the impact of carp growth rate.
Embodiment
For the feature of fish culture pattern, in order to Control experiment error, require that the envirment factors such as feed ingredient are consistent as much as possible in whole breeding process, poultry feeders is not replaced.Concrete operation step is as follows:
(1) carp that this experiment is selected all cultivates in spring culture experiment base, China Aquatic Science Research Academy Fresh Water Fishery Research Center south, and the experimental population of random selecting is same generation carp colony of the Yellow River carp new lines breeding population.Be divided into 3 processed group and a control group, each group has 3 repetitions, each repetition 30 tail, and between each repetition, before experiment, body weight carries out Multiple range test without significant difference (body weight at this moment measured is original body mass), breeding cycle is the feature of 75 days, and 3 kinds of concrete aquaculture models are:
Note: S: represent hungry, F represents compensatory and feeds
Control group fed 75 days, uninterruptedly feeds everyday.
(2) feed is the carp commodity material (Wuxi branch company of Tongwei Co., Ltd.) bought, and each processed group and control group include 3 repetitions, and every day manually throws something and feeds for three times (early 9:00, middle 12:00, late 4:00); Throw something and feed after other group hunger, between feed period, every day manually throws something and feeds (early 9:00, middle 12:00, late 4:00) for three times to being satiated with food.
(3), on the basis of (2), at the end of waiting to test, measure the growth indexes such as the body weight of every bar fish, and carry out statistical analysis by software R3.0.14.Body weight during growth rate=when rear body weight-test initial (experiment terminate body weight)/test initial.Consume feed total amount in feed saving rate=(consume in the whole experimentation of control group in feed total amount-whole experimentation of each processed group and consume feed total amount) whole experimentation of/control group, experimental result is shown in Fig. 1.
Specific growth rate (specific growth rate, SGR):
In formula,
, W2, W1 are respectively corresponding date t2(d) and fish body weight t1(d).
Specific growth rate (specific growth rate of body length, SGRL) based on the long L of body:
In formula, the fish length of corresponding date t2 and t1 of L2, L1 difference.
Specific growth rate (specific growth rate of condition factor K, SGRK) based on coefficient of condition K:
In formula, the coefficient of condition of corresponding date t2 and t1 of K2, K1 difference,
.
In first hunger-compensatory growth stage, namely A group, B group, component C are after not hungry 5 days, 7 days, 15 days, then refeeding 20 days, 28 days and 60 days respectively, and control group Con group is is normally thrown something and fed 15 days, the specific growth rate of A group to be significantly higher than other three groups (
pand three processed group specific growth rates are higher than the specific growth rate of control group <0.05).
Three processed group the long specific growth rate of hungry stage body significantly lower than control group (
p<0.05).From three processed group, the long specific growth rate of body reduces with the increase of starvation time, and processed group C(starvation time is 15) the long growth rate of body to take remarkable be 5 days lower than processed group A(starvation time) and processed group B(starvation time be 7 days) (
p<0.05).That is, along with the increase of starvation time, the growth rate of fish body body length slows down gradually, and wants significantly lower than the fish length specific growth rate under state of normally throwing something and feeding.In the refeeding stage, the long growth rate of body of processed group A and processed group B will be significantly higher than processed group C and control group Con(
p<0.05).
Initial and terminate two each processed group of point with control group compare coefficient of condition difference remarkable (
p>0.05).Compared with initial coefficient of condition, each group of decline all occurring coefficient of condition.But after the hungry stage terminates, the coefficient of condition of processed group C is wanted significantly lower than other three groups; The coefficient of condition terminating post processing group B and processed group C in the refeeding stage still comparatively control group significantly reduce, and processed group A and control group difference not significantly (
p<0.05).This illustrates, reduces, and be not improved after refeeding time the hunger of long-time (15 days) can cause fish body coefficient of condition compared with normal to be thrown something and fed; Long period (7 days) although the hunger remarkable reduction that coefficient of condition compared with normal can not be caused to throw something and feed under state, Restoration stage but can not catch up with group of normally throwing something and feeding; Short-term starvation (5 days), although fish body can be made comparatively to become thin under original state, still can keep normal coefficient of condition after being through refeeding.
After experiment terminates, there is not significant difference in each processed group and control group, growth rate does not also exist significant difference between two, and find through numerical value tendency chart, experimental group A effect is better.When not having statistics growth differences, it is that 8.7%, processed group B to save feed rate be that 5.9%, processed group C to save feed rate be 7.4% that processed group A saves feed rate, is still processed group A best results.
Comprehensive above step, we can obtain a kind of method being improved carp culture production efficiency by hunger-compensatory growth aquaculture model, the method can make sample size be 360 carp colony relatively cultivate growth rate improve, feed saving rate is the mean value of 7.3%(3 process), this is the excitation accelerated carp growth of bright compensatory growth on the other hand also.
