Abstract

Results of our study show that juveniles of the mangrove red snapper are found all year round from the Cua Dai river mouth to Cam Kim upstream of the Thu Bon estuary, with no clear patterns of distribution between months. Variability in recruitment of juvenile fish of ≤50 mm TL was observed from June until February, and the youngest fish (≥18 mm TL) were found in mid-June. Adult mangrove red snapper TL ≥400 mm were only recorded from coral reef offshore islands. There is likely a connection between both fish habitats separated by a distance of approximately 18 km. The results of red snapper DNA analysis show homogeneity of juveniles and adult the population structures.

摘要

我们的研究结果表明，从库代河河口到星期四Bon河口上游的Cam Kim，全年都发现了红树林鲷鱼的幼体，并且在两个月之间没有明显的分布模式。从6月到2月观察到≤50毫米TL的幼鱼募集的变化，并且在6月中旬发现了最小的鱼类（≥18毫米TL）。TL≥400 mm的成年红树林红鲷鱼仅在珊瑚礁近海岛屿上记录到。两条鱼的栖息地之间可能存在联系，两者之间的距离大约为18 km。红鲷鱼DNA分析的结果表明，青少年和成年种群结构具有同质性。
