Description
Technical field
The present invention relates to a kind of trout production technology, belong to fishery cultivating field, specifically a kind of production method of trout seed.
Background technology
Roe has very high nutritive value, the nutritional labeling that contains the needed by human body such as ovalbumin, globulin, ovomucoid and ichthyn, delicious flavour.Trout spur is few, delicious meat, there is higher nutritive value, trout seed nutritive value is higher, its nutritional labeling comprises: moisture 59.96%, protein 31.74%, fat 4.34%, ash content 3.06%, and contain abundant vitamin and mineral matter also contains easily digested essential amino acid.Being subject to interests to order about people is all that the ripe trout that is about to lay eggs of fishing for natural water area produces trout seed, a large amount of catches and kills the trout also not laying eggs, and causes trout resource seriously to reduce, heavy damage trout natural resources, directly threaten the ecological balance.
Few to trout seed production technology research report both at home and abroad, Liu Xuexun, the Wang Xiulin that only has Beijing Fisheries Research Institute made simple Preliminary report " rainbow trout feminizes and the Primary Study of roe nutrition and processing ", by application female hormone induction rainbow trout, feminize, with a large amount of ripe raun obtaining, carry out the processing of caviar, and the trophic component of rainbow trout caviar has been carried out to simple analysis, then without other about trout seed production technology research report.
Summary of the invention
The present invention overcomes the deficiencies in the prior art; a kind of production method of trout seed is provided, and its object is to overcome the deficiency of the salmon trout production trout seed of catching and killing natural spawning, has effectively protected salmon trout natural resources; safeguarded the ecological balance, for the science production technology of trout provides a kind of new method.
The production method of a kind of trout seed of the present invention, is characterized in that: cultivation trout reaches sexal maturity, in mating period, selects the development of ovary to arrive the trout parent population of V phase, takes the method for extruding to extrude trout ovum; 4 ℃ following with 0.5～5% concentration without iodine common salt water logging, wash trout ovum, then use the pickled without iodine common salt water of suitable concentration, with gauze, drain away the water, after disinfection by ultraviolet light, pack.
The production method of a kind of trout seed of the present invention, specific implementation step is:
A. squeeze the selection of the female trout of ovum: female trout is adopted ovum first trimester and in feed, adds 40～60ppm astaxanthin, and the female trout that will produce roe stops eating three days, pulls the female trout that can extrude gently ovum grain out, wait for and squeeze ovum;
B. trout live body squeezes ovum technology: a people pinches the caudal peduncle of fish, and another people's both hands are caught fish head, and cleans dripping of fish body, then trout gonopore is aimed at and is connect egg apparatus ware, by rear, to front repeated multiple times light and slow extruding, guarantees to squeeze clean as far as possible;
C. clean trout ovum: by the trout ovum of extruding 4 ℃ of following washing without iodine common salt water logging by 0.5～5% concentration, stir gently, trout ovum proportion is greater than water, sink to container lower floor, the egg membrane and other organic organization that swim in upper strata are removed, so repeatedly clean 4～5 times, egg membrane and other foreign matter are all cleaned up; Use again the pickled without iodine common salt water of suitable concentration, with gauze, drain away the water, packing after disinfection by ultraviolet light, trout seed color and luster, the mouthfeel of production and to fish for the trout seed difference of natural salmon trout production little.
The selection of described trout takes to see, touches, crowded way, the mature condition of judgement raun, if can extrude gently ovum grain, stay and wait for crowded ovum, if can not extrude ovum grain, continue cultivation and reexamine to next time, from starting for the first time to check, every 7～10 days, reexamine once, until raun all can be extruded to ovum grain.
Described trout squeezes ovum technology, wherein the ovum in trout body must be extracted only as far as possible, otherwise be had a strong impact on the next year quality of ovum; Connect egg apparatus ware bottom and be furnished with aperture, allow ovary tissue liquid flow out.
The unnecessary fertilization of fish-egg of described production trout seed, but must the foreign substance cleaning such as tissue fluid such as ovary liquid in ovum grain is clean, cleaning can not make fish-egg imbibition, egg membrane thickening, hardening, can not produce harmful material, food security standard be must meet, natural form and the nutrition of trout seed also must be maintained.
A kind of method of producing trout seed of the present invention, its beneficial effect is: the trout seed of production reaches pollution-free food standard, and has natural form, and nutrition is of high nutritive value; Method of operating is simple, convenient, without complex device; By producing trout seed, extend the industrial chain of trout, improve culture benefit, more avoid fishing for the drawback that wild trout produces trout seed, protection trout resource, maintaining ecological balance.
