1st, be utilized respectively the fry that the eastern star spot of opening material cultivation of Examples 1 to 5 has just been hatched, using natural bait as pair According to progress culture experiment.
2nd, experiment packet
The eastern star spot fry that same batch has just been hatched is selected, is divided into six groups and is tested, every group of 3 repetitions, Mei Gechong Multiple 2000 tails or so fry.Data statistics is averaged.
Feeding management is operated according to conventional cultivation field.It is fed once every timing in 2-4 hours in daily.
3rd, result counts
Observation statistics initial feeding situation, record have fry to start the time ingested for the first time.In order to reduce mistake as far as possible Difference, three batch datas of three repetitions of each group are completed by three personal responsibilities, are as a result averaged respectively.
It counts each group and respectively repeats fry Initial total weight and the total weight after 30 days, calculate and increase weight in 30 days.
Rate of body weight gain (%)=100 × (last weight-initial weight)/initial weight
The survival rate of fry after statistics calculates 45.
Meanwhile it counts and calculates feed conversion rate and specific growth rate：
Feed conversion rate (%)=100 × (last weight-initial weight)/feed weight
Specific growth rate (%)=100 × (ln ends weight-ln initial weight)/t (cultivation number of days)
4th, the results are shown in Table 1.
Table 1
By experimental result it is found that in the eastern star spot dedicated openings material of the present invention, each component and its proportioning form coordination Unified organic whole shows apparent synergistic function, can improve opening effect, is obviously improved the food calling of feed Property, eastern star spot juvenile fish are liked ingesting, and contribute to the growth and development of fry.Moreover, feed conversion rate is high, it can significantly improve and survive Rate and growth rate.
Embodiment 7
Based on embodiment 1, the difference lies in be respectively all changed to bacillus subtilis and Rhodopseudomonas palustris Strain shown in table 2, is tested, and method is the same as embodiment 6.Every group sets 3 repetitions, and results are averaged.As a result such as 2 institute of table Show.
Table 2
The results show that for the juvenile fish seedling for the phase that is open, different microorganisms strain not only has an impact the opening effect of fry, And growth and development and the survival rate of eastern star spot fry are had an effect on, with being combined as bacillus subtilis and Rhodopseudomonas palustris Most preferably.
Embodiment 8
Method reference implementation example 6, the difference lies in：It is fry opening to be hatched to feed feeding time, and schistostoma broadens Afterwards, start to feed feed；Statistics has that fry starts to ingest the time and fry more than half ingests the time.The results are shown in Table 3.
Table 3
By experimental result it is found that the eastern star spot dedicated openings material of the present invention has significant attractant, eastern star spot juvenile fish happiness It vigorously ingests, contributes to the growth and development of fry.
Embodiment 9
1st, based on embodiment 1, the difference lies in the food calling combinations replaced in feed, prepare a series of opening materials, It is tested；Screen best food calling scheme.Every group sets 3 repetitions, and results are averaged.
Method reference implementation example 6, the difference lies in：It is fry opening to be hatched to feed feeding time, and schistostoma broadens Afterwards, start to feed feed.
2nd, the results are shown in Table 4
Table 4
Experimental result shows that eastern star spot fry has apparent feeding preference, for the juvenile fish seedling for the phase that is open, different food callings Combining the attractant effect to eastern star spot fry has significant difference.By data it is found that eastern star spot opening phase fry more preference Radix Astragali and the combination of Hericium erinaceus.
Embodiment 10
The state of feed in water mainly swims in the water surface, suspends in water, sinks under water three kinds.Various aquatic livestocks Due to life habit difference, the requirement to the sink-float of feed is also different.Usual aquatic seedling water feeding at the middle and upper levels, due to The prelarva travelling ability just hatched is weak, and prey ability is poor, in continual feeding state, to the rate of settling of open-mouthed bait with Water stability (dry matter retention rate) proposes higher requirement.
The feed that the present embodiment is prepared with embodiment 1 tests the property of opening material of the present invention, stablizes including suspension and water Property.
1st, test method
The detection of suspension：The suspension of feed is often weighed with suspensibility.100ml distilled water is added in 100ml beakers, Weigh certain mass m1(g) feed is uniformly spread on distillation water surface, after standing a period of time, is taken out and suspended along liquid level with pipette Suspended solid after filtering, is put into 80 DEG C of baking ovens that drying to constant weight, obtains solid, quality is respectively labeled as m by liquid2(g)。
Suspensibility (%)=m2/m1×100
The water stability of feed measures the method with reference to U.S. feed Industry Association, feed mg is taken, as the sieve of 200 mesh On uniformly spread out and be slowly put into 27 DEG C of glass containers for filling 40L deionized waters, impregnate respectively 10min, 30min and 1h, 2h, 4h, 6h, 12h take out sieve, dry, weigh, and calculate different soaking time feeds respectively to dry matter retention rate, every group If 3 repetitions, water stability is the percentage that final dry matter weight accounts for initial dry matter weight.
2nd, the results are shown in Table 5, and opening material of the invention has excellent suspension and water stability.
5 feed water dispersible of table and water stability (suspensibility, %)
Index 10min 30min 1h 2h 4h 8h 12h
Suspension 95.72% 70.73% 65.82% 61.95% 58.32% 46.39 39.45%
Water stability 96.83% 92.22% 88.83% 84.01% 79.12% 60.53% 53.13%
Above-described embodiment is the preferable embodiment of the present invention, but embodiments of the present invention are not by above-described embodiment Limitation, other any Spirit Essences without departing from the present invention with made under principle change, modification, replacement, combine, simplification, Equivalent substitute mode is should be, is included within protection scope of the present invention.
