Juvenile Fish Diversity in Shankou Mangrove Reserve and Their Recruitment to the Fishery Resources
摘要
Abstract
The data were collected through juvenile fish surveys in Shankou Mangrove Reserve in April,October 2010 and January, May,July 2011 respectively,which covered 4 seasons year-round. 33 and 28 species were found at the mudflat and creek of Shankou mangrove area respectively,all the species were bony fish. The dominant species varied with seasons. The dominant species in the mudflat were Mugil ophuyseni and Lateolabrax japonicas in spring (April and May) ;Stolephorus indicus in autumn (October) ,M. ophuyseni in winter (January) ,Leiognathus brevirostris and Clupanodon punctatus in summer (July). The dominant species in the creek were Ambassis gymnocephalus and C. punctatus in spring;L. brevirostris in autumn;M. ophuyseni and Tridentiger trigono-cephalus in winter;and Acentrogobius caninus in summer. Species biodiversity indices of the juvenile fish were calculated. The species richness D,Shannon diversity index H' and evenness index / were 1. 83,1. 5 and 0. 53 at the mudflat and 1. 63,1. 46,0. 58 at the creek respectively. Compared with other mangrove areas, the biodiversity indices of juvenile fish were lower in Shankou mangrove are-a. By analyzing habitat shifting of Engraulidae.Clupeidae and Mugilidae.it could be concluded that Shankou mangrove provided nursery area and shelters for the juvenile fish, which played an important role of recruitment to local fishery resources.关键词
