Abstract

ABSTRACT: The aim of this study was to understand the relationship between acoustic characteristics and body size of Korean rockfish Sebastes schlegelii in order to better estimate the body length of S. schlegelii by passive acoustic techniques. In this study, S. schlegelii, with a body length ranging from 21.7 to 24.8 cm (mean ± SD = 23.33 ± 0.93 cm) and a body weight of 144.2 to 250.3 g were selected as subjects. The aim was to explore the relationship between the acoustic characteristics of the fish and their standardized lengths through aquarium experiments. The vocalization frequency exhibited a main peak at around 150 Hz, a sub-peak at approximately 100 Hz, and the primary vocalization band extended from 100 to 350 Hz, with a pulse duration of 15.2 ± 2.4 ms. The results indicated that the peak frequency was negatively correlated with the standardized length, swim bladder length, width, and height (p <0.001). This research contributes to the understanding of the relationship between acoustic properties and body size and suggests the potential utility of passive acoustic monitoring techniques for estimating the body lengths of target species.

韩国石首鱼（Sebastes schlegelii）产生的声音特性与鱼体和鱼鳔大小的关系

摘要：本研究旨在了解韩国石首鱼（Sebastes schlegelii）的声学特征与体型之间的关系，以便通过被动声学技术更好地估计石首鱼的体长。本研究选择了体长为 21.7 至 24.8 厘米（平均值 ± SD = 23.33 ± 0.93 厘米）、体重为 144.2 至 250.3 克的石首鱼作为研究对象。目的是通过水族箱实验探索鱼类的声学特征与其标准化体长之间的关系。发声频率的主峰在 150 Hz 左右，次峰在 100 Hz 左右，主发声频带从 100 Hz 扩展到 350 Hz，脉冲持续时间为 15.2 ± 2.4 ms。结果表明，峰值频率与标准化长度、鳔长、鳔宽和鳔高呈负相关（p <0.001）。这项研究有助于理解声学特性与体型之间的关系，并表明被动声学监测技术在估计目标物种的体长方面具有潜在的实用性。

期刊介绍： AB publishes rigorously refereed and carefully selected Feature Articles, Research Articles, Reviews and Notes, as well as Comments/Reply Comments (for details see MEPS 228:1), Theme Sections, Opinion Pieces (previously called ''As I See It'') (for details consult the Guidelines for Authors) concerned with the biology, physiology, biochemistry and genetics (including the ’omics‘) of all aquatic organisms under laboratory and field conditions, and at all levels of organisation and investigation. Areas covered include: -Biological aspects of biota: Evolution and speciation; life histories; biodiversity, biogeography and phylogeography; population genetics; biological connectedness between marine and freshwater biota; paleobiology of aquatic environments; invasive species. -Biochemical and physiological aspects of aquatic life; synthesis and conversion of organic matter (mechanisms of auto- and heterotrophy, digestion, respiration, nutrition); thermo-, ion, osmo- and volume-regulation; stress and stress resistance; metabolism and energy budgets; non-genetic and genetic adaptation. -Species interactions: Environment–organism and organism–organism interrelationships; predation: defenses (physical and chemical); symbioses. -Molecular biology of aquatic life. -Behavior: Orientation in space and time; migrations; feeding and reproductive behavior; agonistic behavior. -Toxicology and water-quality effects on organisms; anthropogenic impacts on aquatic biota (e.g. pollution, fisheries); stream regulation and restoration. -Theoretical biology: mathematical modelling of biological processes and species interactions. -Methodology and equipment employed in aquatic biological research; underwater exploration and experimentation. -Exploitation of aquatic biota: Fisheries; cultivation of aquatic organisms: use, management, protection and conservation of living aquatic resources. -Reproduction and development in marine, brackish and freshwater organisms
