作为巴利阿里群岛（W。地中海）标本圈养和实验，以确定最佳的批标记程序之前，释放进行。在盐度为37（每毫升）时，用土霉素标记未成熟鱼耳石失败，而浓度为60 mgL − 1的茜素红浴22 h被证明在>90%的耳石中成功，死亡率低（<8%）。无论鱼的年龄或标记后经过的时间如何，标记都存在。对53-305日龄的鱼进行了耳石生长增量的每日性质的验证。耳石和鱼类的生长表现出变异性，这取决于年类和水温，与增长率低于那些经历了在野外。
As part of meagre (Argyrosomus regius) restocking programme in the Balearic Islands (W. Mediterranean) specimens were reared in captivity and experiments to determine the best batch marking procedure prior to release were carried out. Immature fish otolith marking with oxytetracycline failed to mark the otoliths at 37 (per mil) salinity, while alizarine red bath at a concentration of 60mgL−1for 22h proved to be successful in >90% of the otoliths, with low mortality rates (<8%). The mark was present irrespective of fish age or of time elapsed since marking. The daily nature of the otolith growth increment was validated for fishes 53–305 days of age. Otolith and fish growth showed variability depending on year class and water temperature, with growth rates lower than those experienced in the wild.
