研究了维生素C(AsA)改善幼鱼补种品质的几个参数。将添加不同水平的L抗坏血酸-2-磷酸-镁(APM)的干颗粒饲料(0、400、1000、2000 mg/kg饲料)分别饲喂给500尾幼鱼(平均全长3.6 cm)，每个处理组(500只L圆形)。试验日粮在25°C水温下每天饲喂3次，连续20天。在为期20天的试验后，每组随机抽取10到20名青少年进行空中跳水和学习行为测试。进行“空中潜水”，以确定暴露在空气中的幸存者人数，同时使用视频系统记录学校行为，如学校模式、游泳活动和个人距离，并通过计算机图形系统进行分析。存活率超过90%，在20天的试验中，任何一组都没有出现AsA缺乏的迹象。APM摄入量对仔猪生长无明显影响。肝脏ASA随着APM摄入量的增加而增加，而脑ASA在1000 mg APM时趋于平稳。饲喂不含APM饲料的鱼对空气暴露的耐受性似乎很差，尽管没有检测到统计学意义(P>；0.05)。摄食含有1000或2000毫克APM的饲料的鱼的成活率明显更高。推测以含APM 1000 mg以上的饲料饲养的黄鱼幼鱼在自然条件下放生后能表现出较好的生长和存活能力。
Several parameters were investigated to determine the effects of vitamin C (AsA) on improvement of juvenile yellowtail quality for restocking. The dry pellets with different levels of l-ascorbyl-2-phosphate-Mg (APM) (0, 400, 1000, and 2000 mg/kg diet) were formulated and fed to 500 juveniles (mean total length (TL): 3.6 cm) per treatment with duplicate tanks (500 l round type). Test diets were fed three times a day at 25°C water temperature for 20 days. After the 20-day trial, 10 to 20 juveniles from each treatment group were randomly sampled for a test of `air dive' and schooling behavior. The `air dive' was conducted to determine the number of survivors after exposure to air while the schooling behavior such as schooling pattern, swimming activity and individual distance were recorded using the video system and analyzed by the computer graphic system. Survival was over 90% and there was no sign of AsA deficiency in any group during the 20-day trial. There was no effect of APM intake on growth. Liver AsA increased with increasing APM intake whereas that of brain AsA levelled off at 1000 mg APM. The tolerance against air exposure seemed poor in fish fed on APM-free diet although statistical significance was not detected (P>0.05). The schooling rate was significantly higher in fish fed on diets containing 1000 or 2000 mg APM. It is speculated that juvenile yellowtail fed on diet containing more than 1000 mg APM would be able to show better growth and survival under natural conditions after release.
