鳗鲡仔鱼微型胶囊饵料的初步研究

Preliminary Study on Microencapsulation of Artificial Diets for Larvae of Japanese Eel ( Anguilla japonica )

制备了囊心物为液态的 ,含脂溶性营养物 (lipidicsolubilitynutriment,LSN)及水溶性营养物 (watersol ubilitynutriment,WSN)的明胶 (GT)—羧甲基纤维素 (CMC)微型胶囊饵料。制备方法为将WSN和LSN分别溶入适量水和鱼油中 ,再将水与鱼油制成W/O乳剂 ,最后以GT、CMC为囊材将乳滴包裹成微囊。平均囊径为41 2 μm。对鳗鲡 (Anguillajaponica)仔鳗的投喂实验表明 ,微囊饵料加上天然饵料可使仔鳗存活 15d ,而只投喂天然饵料的仔鳗只存活了 8d。

The Gelatin-Sodium Carboxymethyl Celluose-Microcapsule which contained water solubility nutriment(WSN) and lipidic solubility nutriment(LSN) was prepared.The average diameter of the microcapsule was 41 2μm.The eei larvae survived 15 days after fed with the microcapsule plus natural feed(such as rotifer),while the control group treated with natural feed survived only 8 days.
