Spread contraceptives and feed the rice field eel in Wuhan The expert spikes a rumour and claims not to have scientific basis at all
Do the rice field eels on the market all feed the great one with contraceptive? Yesterday, said to this market, the centre for spreading aquatic products science and technology of the city were refuted with the expert of Academy of Agricultural Sciences of city unanimously: Not having scientific basis to feed the rice field eel with contraceptive, have not found this kind of situation either in the rice field eel of our city cultivates. Yesterday, the municipal bureau of agriculture invited the aquatic products expert to attend the special examination aquatic products quality safety in Chinese south district. In rice field eel's cultivation base of 2333.333 hectares of Chinese south Hunan mouth street, the aquatic products centre for spreading senior engineer Tang DeWen of science and technology of the city introduce, the rumor among the workshops " Contraceptive is fed to the rice field eel " Sheerly incorrectly relay an erroneous message, there is not any scientific basis. DeWen Tang introduce, rice field eel special the intersection of one and aquatic products very, go through numerous, reverse in the all one's life, the rice field eel is female in the first year, male and female and body of the second year, by third year, basically all turn into male. Our city network case cultivates the rice field eel and generally selects to use the wild yellow eel seedling for more than 2 years, it is generally the male after listing, and contraceptive takes estrogen as the core, such as using at this stage, the rice field eel will maintain at female stage, only eating the feed will no one will grow, lose more than gain. Moreover, the bodily form of the usually male rice field eel is relatively big, the female rice field eel is relatively small, only the yellow eel becomes male, one grows more, profitable to the raiser. City the intersection of Academy of Agricultural Sciences and the intersection of aquatic products and the intersection of research institute and bright red think senior engineer Hua introduce, our city the intersection of network and case cultivate, throw in the intersection of yellow eel and time of Miao generally at the beginning of July at the end of June, at this moment, the water temperature is more steady, it is better to cultivate benefit. And rice field eel breeding period April - May, pass breeding period, have any function to introduce contraceptive on to, meanwhile, because the yellow eel grows seedlings and has not captured yet manually, uses the wild yellow eel seedling at present, it is difficult to throw in contraceptive. The people of Chinese Nanwang rice field eel cultivate ShaoHai Hu, person in charge of cooperative society, introduce, Chinese south the intersection of net and case cultivate rice field eel use water earthworm and small fish shrimp,etc. animal fodder the main fact, complement it with the regular artificial feed. Tang DeWen says, the artificial feed will contain certain growth hormone, contain certain growth hormone in the feed such as pig, ox, sheep, fish. But only the qualified feed of regular producer's production, this kind of use belongs to the safe controllable range. Zhu SiHua says, really looks more thick to propagate the rice field eel artificially, the main reason is, the existence condition raised manually is much better than that of the field, the food is sufficient, it is all male and go on the market, perhaps on the mouthfeel this kind of yellow eel can not compare with the wild yellow eel, but can never be harmful to human body.
