Abstract

Antipredator behavior was used as a parameter to detect effects caused by exposure to the organotin compound bis(tributyltin)oxide (TBTO). Three groups of threespine sticklebacks (Gasterosteus aculeatus L.) were exposed to 3, 9 and 27 ppb TBTO, respectively. A fourth control group was given the same treatment as the other three groups, but no TBTO. Antipredator behavior of the fish was evoked using a dummy heron (Ardea cinerea) bill. TBTO exposure caused significant changes in the spatial position of the fish in the aquarium (P(Loc)), their response to predator attack (P(Res)), recovery time (P(Rec)) and latency time (P(Lat)). Some of the effects were, however, reversible after the exposure was terminated. We suggest that behavior as an indicator of pollution may be used as an ecologically relevant integrative biomarker.

摘要

反捕食行为被用作一个参数，以检测暴露于有机锡化合物双（三丁基锡）氧化物（TBTO）所产生的影响。三组三刺鱼（Gasterosteus aculeatus L.）分别暴露于3、9和27 ppb的TBTO中。第四组作为对照组，给予与其他三组相同的处理，但不添加TBTO。使用假苍鹭（Ardea cinerea）喙诱发鱼的反捕食行为。暴露于TBTO导致鱼在水族箱中的空间位置（P(Loc)）、对捕食者攻击的反应（P(Res)）、恢复时间（P(Rec)）和潜伏期（P(Lat)）发生显著变化。然而，在暴露终止后，一些影响是可逆的。我们建议，行为作为污染的指标，可作为一种具有生态相关性的综合生物标志物。
