鱼类耳石研究和应用进展

Present status of studies and applications on otolith of fishes

鱼类耳石研究是鱼类生长和早期生活史研究的基础。文章阐述了鱼类耳石形态的研究方法及其在鱼类种类识别中的应用、耳石微结构在鱼类年龄鉴定、早期生长研究、产卵期、孵化期和产卵场的推算以及早期生活史中特殊事件的研究等方面的进展,探讨了耳石研究的存在问题并提出了进一步研究的建议。

Studies of otolith are the basic of research on growth and early life history of fishes.The present status on the methods of studying otolith morpha and its application on species discrimination are expatiated in this paper,as well as back-calculations on age determination,early development research,spawning period,hatchery phase,spawning area and special circumstance in early stage by otolith microstructure.The existent problems on research of otolith are discussed and proposals are suggested.
