Description

A kind of mixed feed that strengthens dace parent population fertility
Technical field
The present invention relates to a kind of mixed feed of dace parent population fertility, relate in particular to a kind of mixed feed that strengthens dace parent population fertility; Belong to fish meal technical field.
Background technology
Dace is under the jurisdiction of Cypriniformes, Cyprinidae, labeoninae, dace genus, is commonly called as native dace, snow dace, flower dace.Dace body is longer, and both sides are flat-sided, and swell slightly in dorsal fin the place ahead at back, and belly circle and slightly straight is short and small, and kiss circle is blunt.Young, the next, curved, upper lower jaw tool cutin sharp-edged, two pairs of palpuses, kiss must be more sturdy.Dace is the important economic freshwater fish in China South China, and inexpensive, the market demand is continuous.Its fine and tender taste, delicious flavour, output is large, per unit area yield is high, and feed resource is wide, can adapt to more fertile water body environment, the indispensable kind of resistance against diseases Qiang Shi South China pond culture.But the formula technique patent about dace parent population feed have not been reported at present, be therefore extremely necessary to develop a kind of dace parent population feed, to promote the sustainable development of China's dace aquaculture.
Although China's dace reproduction technique is more ripe, but main dependence reaches the object of hastening parturition with hormone or hormone analogs, these hormones and hormone analogs exhaust agent etc. and belong to chemicals as gonadotropin-releasing hormone (GRH), dopamine antagonist, dopamine disappear, the long-term use of these chemicals has not only caused the problems such as the decline of parent population fertility, seed degeneration, environmental pollution, and its residual and enrichment in seed also can affect human body health.When parent population is hastened parturition, use the ID of these hormones and hormone analogs excessive or not enough, easily cause the parent population death rate to increase, rate of fertilization and spawning rate reduce.And in use, all can cause hastening parturition unsuccessfully evening too early or excessively.In addition, in the process of hastening parturition careless manipulation can cause parent population damage and parent population scaring stress, cause parent population do not produce or have difficult labour, even cause parent population dead, to culturist, bring serious economic loss.
Therefore, for overcome troublesome poeration in current dace parent population breeding artificial induced spawning process, stress be greatly, damage the artificial induced spawning technology that risk is high and overcome the hormone of prior art and the caused seed degeneration of chemicals such as analog, environmental pollution, residual and natural conditions under the low inferior problem of dace fertility, and develop a kind of nutritious, environmental protection, can strengthen the feed of dace parent population fertility, for the reproductive capacity, the development of artificial induced spawning technology and the sustainable development of culture fishery that improve dace parent population, all there is important theoretical and practical significance.
Summary of the invention

In order better to illustrate, effect of the present invention provide the mixed feed of the strengthened dace parent population fertility providing in embodiment 3 below to dace parent population culture experiment.
For the impact on dace parent population sexual gland, growth etc. of mixed feed that the strengthened dace parent population fertility that contains medicinal herb components is described, the present invention's diameter is 2m, high 3m, and the cylindrical cement culturing pool that inner surface is smooth is cultivated dace parent population.4 of cement pits are side by side established in experiment altogether, are divided at random 2 groups, every group of two repetitions, i.e. and every group of two culturing pools, put in a suitable place to breed respectively with a collection of and have cultivated dace 200 tails that body weight reached the sex immature of the same age of 357.6g and carry out dace parent fish rearing cultivation.Wherein one group of mixed feed that strengthens dace parent population fertility of the present invention of throwing something and feeding, as experimental group, is designated as T; The commodity dace mixed feed that another group is thrown something and fed common, as a control group, is designated as C; The feeding volume of two groups is 3% ~ 5% of dace body weight, throws something and feeds every day 3 times (8:00,14:00,16:00), in cultivation time from January then, finishes 6 months by a definite date altogether to June in the same year.
Cultivation throw something and feed experiment finish after, the 24h that stops eating, each cement pit is got respectively female dace 30 tails, weighs.After dissecting on ice pan, take out ovary, weigh, and calculate ovary maturity coefficient.The ovary membrane that breaks in physiological saline, takes out egg mother cell, and under inverted microscope, the parameters such as diameter of Observe and measure egg mother cell, specifically see the following form.
The ovary contrast of table 1 feed of the present invention and commercial feed cultivation dace parent population
Figure BDA0000306317921
As can be seen from the above table, the culture experiment effect that feed of the present invention is cultivated dace parent population is remarkable, except dace parent population body weight is significantly higher than general goods feed culture efficiency, feed of the present invention promote dace parent population sexual gland grow aspect effect also significantly better than common commercial feed, wherein the weight of stages of gonad development, ovary is, the diameter of egg mother cell and mature coefficient are all better than control group.
Above-mentionedly experiment showed, that the mixed feed that strengthens dace parent population fertility of the present invention all has good effect at aspects such as promoting dace growth, sexual gland growth, maturity and egg mother cell diameter.Can well be applied.
