Embodiment 6
1st, the fry that the European hyoid tooth perch of opening material cultivation of Examples 1 to 5 has just hatched is utilized respectively, with the natural of routine
Bait is control, carries out culture experiment.
2nd, experiment packet
The European hyoid tooth perch seedling that same batch has just been hatched is selected, is divided into six groups and is tested, every group of 3 repetitions, often
A 2000 tail of repetition or so fry.Data statistics is averaged.
Feeding management is operated according to conventional cultivation field.It is fed every timing in 2-4 hours primary.
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.By experimental result it is found that in the European hyoid tooth perch dedicated openings material of the present invention, each group
Divide and its match the organic whole for foring the coordinating and unifying, show apparent synergistic function, opening effect can be improved,
The attractant of feed is obviously improved, European hyoid tooth perch juvenile fish is liked ingesting, and contributes to the growth and development of fry.Moreover, feed turns
Rate is high, can significantly improve survival rate and growth rate.
Table 1
Embodiment 7
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 2.
Table 2
By experimental result it is found that the European hyoid tooth perch dedicated openings material of the present invention has significant attractant, European hyoid tooth
Perch juvenile fish is liked ingesting, and contributes to the growth and development of fry.
Embodiment 8
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 3
Table 3
Experimental result shows that European hyoid tooth perch seedling has apparent feeding preference, different for the juvenile fish seedling for the phase that is open
The attractant effect that food calling combines to European hyoid tooth perch seedling has significant difference.By data it is found that the European hyoid tooth perch opening phase
The combination of fry more preference Rhizoma Gastrodiae and straw mushroom.
Embodiment 9
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 4, and opening material of the invention has excellent suspension and water stability.
