于1999年分4个季度采用拦网的方法对广西英罗港红树林潮沟潮水中鱼类的多样性进行了研究，共发现鱼类 54种，隶属于 29科 44属。季度出现频数F= 1－4的鱼类种数分别为 27、8、11和 8种。各季的优势种明显，但不同季节最大优势种不同，分别为：春季，斑■（Clupanodon punctatus）；夏季，前鳞骨鲻（Osteomugil ophuyseni）；秋季，眶棘双边鱼（Ambassis gymnocephalus）；冬季，鹿斑■（Leiognathus ruconius）。这些鱼类以暖水性种占绝对优势，在生态类型上以底层种类较多。各季节出现鱼类种数分别为：春季30种、夏季30种、秋季26种、冬季22种。夏季与秋季共有种最多，有20个种，这两季节间的相似性指数也最大，达55．6％。多样性指数D、H’、J值均以秋季最高。相对于林外水域，红树林潮沟鱼类群落的鱼类种数及3个指数均较高。跟热带红树林区相比，广西英罗港红树林潮沟鱼类群落的多样性低。
In 1999, 4 species of fish were collected from tidal flats of the mangrove tideway at Yingluo Harbor, Guangxi. Four fish species were found, belonging to 29 families and 44 genera. Quarterly occurrences of F = 1-4 fish species were 27,8,11 and 8 species. The dominant species in each season were obvious, but the biggest dominant species in different seasons were: spring, Clupanodon punctatus, Osteomugil ophuyseni in summer, Ambassis gymnocephalus in autumn, , Deer spot ■ (Leiognathus ruconius). These species of fish are dominated by warm water species, with more types of bottom on the ecological type. The species of fish appeared in each season were: 30 species in spring, 30 species in summer, 26 species in autumn and 22 species in winter. There are 20 species in summer and autumn, and the similarity index between these two seasons is also the largest, reaching 55.6%. Diversity index D, H ’, J values are the highest in autumn. Compared with the waters outside the forest, mangroves tidal flats fish community species and three species were higher. Compared with the tropical mangrove area, the diversity of the mangrove tide-gap fish community in Yingluo Bay in Guangxi is low.
