Life-history traits of Lateolabrax latus, one of the popular piscivore species for commercial and recreational fishing along the coasts of western Pacific, were investigated based on 373 specimens collected over a period of 8 years (2011–2018) in a coastal area of southwestern Japan. Histological observation of gonads indicated that the species’ main spawning period is from January to March in this region. Annual periodicity of the otolith opaque zones formed in spring after spawning was validated by the edge-type analysis. The examination of the sectioned sagittal otoliths indicated the maximum age of L. latus as 11 years in both sexes. The species showed early maturation at 2 years of age with body size (standard length) of 379 mm in females and 362 mm in males. Both sexes of L. latus grew rapidly with females attaining larger body size than males of the same age class. The basic life-history information in a wild populations as presented here is considered essential for a better ecological understanding and management of this important predatory fish species.

根据在八年间（2011-2018年）收集的西南沿海地区的373个标本，调查了Laterolabrax latus的生活历史特征，Laterolabrax latus是西太平洋沿岸商业和休闲捕鱼的常见食肉动物物种之一。日本。对性腺的组织学观察表明，该区域的主要产卵期是一月至三月。通过边缘类型分析验证了产卵后春季形成的耳石不透明带的年度周期性。矢状耳石的切面检查显示了L的最大年龄。tus男女均为11岁。该物种显示出在2岁时的早期成熟，雌性为379毫米，雄性为362毫米。劳氏乳杆菌的性别迅速增长，雌性的体形比同年龄段的男性大。这里提出的野生种群的基本生活史信息被认为对更好地了解和管理这种重要的掠食性鱼类至关重要。
