用3组100只大菱鲆幼鱼研究了大菱鲆利用自食器的能力。摄食活动在20天后达到平台期。几乎所有的摄食活动都发生在黎明期，而高峰期与黎明有关。在饲料效率最低的重复中，夜间需求的比例最高，表明饲料浪费主要发生在夜间摄食活动期间。在实验的最后30天里，要求只在两个2.5 h.day-1的时间段内得到奖励。饲料效率提高，并在三个坦克之间是均匀的，但自愿采食量减少。它的结论是，大菱鲆能够使用自我馈线，但他们不适应迅速，他们是无法补偿饲料访问的减少，增加需求活动期间访问。
The capability of turbots to use self-feeders was studied using 3 groups of 100 juveniles. Feeding activity reached a plateau after 20 days. Almost all feeding activity was observed during the photophase, and the acrophase was associated with dawn. The proportion of nocturnal demands was the highest in the replicate with the lowest feed efficiency, suggesting that feed waste was mainly occurring during nocturnal feeding activity. During the last 30 days of the experiment, demands were only rewarded during two periods of 2.5 h.day -1 . Feed efficiency was improved and was homogeneous between the three tanks, but the voluntary feed intake was reduced. It is concluded that turbots are able to use self-feeders but they do not adapt quickly, and they are not able to compensate a reduction of feed access by increasing demand activity during the access period.
