无刺黑岩鱼是日本北海道南部至九州沿岸最重要的渔业物种之一，经常在岩石和Zostera地区发现。我们使用编码超声波发射器进行生物遥测，以澄清居住在关西国际机场海堤的黑岩鱼的运动。我们在两个地点放了25条黑岩鱼。一个是机场海堤，另一个是Sensyu区的侧浅滩。17条黑色岩鱼在释放后返回捕获地点。我们使用V检验来确定运动方向是随机的还是定向的。放流后的几个小时内，黑岩鱼沿海堤沿着随机游动（P > 0.05）。释放后4h，他们有意识地回到自己的家（P < 0.0025）。
The black rockfish Sebastes inermis is one of the most important fishery species along the coast from southern Hokkaido to Kyushu, Japan and is often found in rocks and Zostera areas. We conducted biotelemetry using coded ultrasonic transmitters to clarify the movement of the black rockfish that inhabited the seawall of the Kansai International Airport. We released 25 black rockfish at two points. One was the airport seawall and the other was side shallows off the Sensyu district. Seventeen black rockfish returned to their capture site after release. We used the V-test to deter- mine whether the direction of movement was random or orientated. The black rockfish moved at random along the seawall within some hours after release (P > 0.05). Four hours after release, they moved to their home site intentionally (P < 0.0025).
