Abstract

ABSTRACT The determination of ovarian stages is essential for an understanding of reproductive biology and informing sustainable management of commercially caught marine organisms. This research developed improved microscopic assessment criteria for the prawn, Penaeus (Melicertus) latisulcatus, by reviewing microscopic criteria used in the literature and assessing cell composition of ovary tissue from 97 females. Whilst histological staging is not a new technique, this research outlines new development criteria for assessing ovary development stages in P. latisulcatus. A principal component analysis (PCA) was used with the microscopic classification system and showed distinct groups for each stage. Based on the proportion of cell types, distinct groupings were apparent, which corresponded to the main microscopic stages, in particular for stage 3 ovaries. This revised classification will improve the accuracy of ovarian staging techniques for P. latisulcatus and can be used as a guide for the interpretation and analysis of macroscopic stages during seasonal spawning events for the purpose of better informing fisheries management.

西方对虾(Penaeus) (Melicertus) latisulcatus Kishinouye 1896)卵巢阶段的显微分析

卵巢分期的确定对于理解生殖生物学和为商业捕捞海洋生物的可持续管理提供信息至关重要。本研究通过对文献中常用的对虾(Penaeus (Melicertus) latisulcatus)的显微评价标准进行综述，并对97只雌性对虾卵巢组织的细胞组成进行了评价。虽然组织学分期不是一项新技术，但本研究概述了新的发展标准来评估P. latisulcatus卵巢发育阶段。主成分分析(PCA)与显微分类系统相结合，显示出不同阶段的不同类群。根据细胞类型的比例，不同的细胞类型有明显的分组，这些分组与主要的显微阶段相对应，特别是第三阶段的卵巢。修订后的分类将提高大斑鲟卵巢分期技术的准确性，并可作为解释和分析季节性产卵过程中宏观分期的指南，以便更好地为渔业管理提供信息。

期刊介绍： Published since 1880, the Transactions of the Royal Society of South Australia is a multidisciplinary journal that aims to publish high quality, peer-reviewed papers of particular relevance to Australasia. There is a particular focus on natural history topics such as: botany, zoology, geology, geomorphology, palaeontology, meteorology, geophysics, biophysics, soil science and environmental science, and environmental health. However, the journal is not restricted to these fields, with papers concerning epidemiology, ethnology, anthropology, linguistics, and the history of science and exploration also welcomed. Submissions are welcome from all authors, and membership of the Royal Society of South Australia is not required. The following types of manuscripts are welcome: Reviews, Original Research Papers, History of Science and Exploration, Brief Communications, Obituaries.
