Abstract

Ultrasound waves have been employed to control marine biofouling but their effects on fouling organisms remain poorly understood. This study investigated the influence of ultrasound waves on barnacle (Tetraclita stalactifera cyprid larvae) pre-settlement behavior. Substrate inspection constituted most of the larval time budget, with a focus on the bottom surface rather than lateral or air–water interfaces. The frequency of substrate inspection decreased at 10 kPa when compared to higher acoustic pressures, while the time spent in the water column had an opposite trend. Various larval swimming modes were observed, including rotating, sinking, walking, and cruising, with rotating being dominant. Barnacle larvae exhibited higher speeds and less complex trajectories when subjected to ultrasound in comparison to controls. The impact of ultrasound waves on barnacle cyprid larvae behavior had a non-linear pattern, with lower acoustic pressure (10 kPa) inducing more effective substrate rejection than higher (15 and 20 kPa) intensities.

超声波对藤壶鲤幼体定居前行为的影响
超声波已被用于控制海洋生物污损,但人们对其对污损生物的影响仍知之甚少。本研究调查了超声波对藤壶(Tetraclita stalactifera cyprid larvae)沉积前行为的影响。底质检查占了幼虫的大部分时间,重点是底面而不是侧面或空气-水界面。与较高声压相比,在 10 kPa 时底质检查频率降低,而在水体中停留的时间则呈相反趋势。观察到幼虫的各种游动模式,包括旋转、下沉、行走和巡游,其中旋转模式占主导地位。与对照组相比,藤壶幼虫在超声波作用下表现出较高的速度和较不复杂的轨迹。超声波对藤壶幼体行为的影响是非线性的,较低的声压(10 kPa)比较高的声压(15 和 20 kPa)能更有效地抑制底质。

期刊介绍: Journal of Marine Science and Engineering (JMSE; ISSN 2077-1312) is an international, peer-reviewed open access journal which provides an advanced forum for studies related to marine science and engineering. It publishes reviews, research papers and communications. Our aim is to encourage scientists to publish their experimental and theoretical results in as much detail as possible. There is no restriction on the length of the papers. The full experimental details must be provided so that the results can be reproduced. Electronic files and software regarding the full details of the calculation or experimental procedure, if unable to be published in a normal way, can be deposited as supplementary electronic material.
