ABSTRACT

Individual acoustic tracking is a valuable tool to understand the behavioral ecology of aquatic species and to inform conservation actions. In this study, we examined the spatial behavior of single individuals of four common coastal fish species (striped red mullet, Mullus surmuletus;corkwing wrasse, Symphodus melops;pollack Pollachius pollachius;and white seabream, Diplodus sargus) in the National Park “Illas Atlánticas de Galicia” (NW Spain). The use of space of these species varied between 237,975 m2 and 48,725 m2, and the number of days that each fish was detected in the study area ranged between 35 and 110 days with weighted residence index ranged between 0.02 and 0.43. Pollackleft the array after 235 days, and was recaptured 342 days after tagging ~10 km south from the study area. The movement of the studied species followed contrasting diel patterns. While white seabream and striped red mullet moved over larger areas during the day, pollackranged over larger areas during the night. This single individual study (‘Solo datasets’) represents a useful baseline for future research projects by providing preliminary knowledge of these poorly known species in the study area.

摘要

个体声学跟踪是了解水生物种行为生态学和告知保护行动的宝贵工具。在这项研究中，我们考察了四种常见的沿海鱼类物种单一个体（条纹红鲻鱼的空间行为，Mullus surmuletus ;娇扁隆头鱼，Symphodus melops ;鳕鱼青鳕;而白鲷，Diplodus sargus）在国家公园“ IllasAtlánticasde Galicia”（西班牙西北）。这些物种的空间利用在237,975平方米和48,725平方米之间变化，研究区域中每条鱼被发现的天数介于35天和110天之间，加权居住指数介于0.02和0.43之间。235天后，Pollack离开了阵列，并在距研究区域以南约10公里处贴上标签后342天被重新捕获。被研究物种的运动遵循相反的迪尔模式。白天白鲷和条纹红鱼在较大区域活动，而夜间则在较大区域巡游。通过提供研究区域中这些鲜为人知的物种的初步知识，这项单独的单独研究（“ Solo数据集”）为将来的研究项目提供了有用的基线。
