Abstract
The present study recorded the population of the goby fish (Perciformes: Gobiidae), Eutaeniichthys cf. gilli Jordan & Snyder, 1901, from the tunnel burrowed by the mud shrimp Austinogebia edulis Ngo-Ho and Chan, 1992 in a mudflat in Shengang and Wangong of Changhua County, western Taiwan. This finding is not only a new record of the genus in Taiwan, it is also the first record of this species in a mudflat near an industrial park. In total, 56 individuals of E. cf. gilli were collected from June 2016 to September 2018. Morphological traits of males and females were measured. The resin casting method trapped bodies of E. cf. gilli that were present in the tunnel burrow and proved that the fish inhabits burrows of the mud shrimp A. edulis. In addition, a species of snapping shrimp was also found in the same tunnel. Symbiotic interaction may occur between E. cf. gilli, A. eduli and the snapping shrimp. The China Coastal Current (CCC) runs along the coastlines of Japan, Korea, China, and reaches western Taiwan during the northeast monsoon period. The CCC, therefore, might play an important role in the biogeographic distribution of E. cf. gilli in the western Pacific Ocean. Since E. cf. gilli is listed in the Red List as an endangered species of Japan for many years, Taiwan waters may provide a refuge for this fish species warranting a broader investigation. Since Taiwan is some distance away from the previously recorded locations in Japan, Korea, the Yellow Sea, and the Bohai Sea, a phylogenic analysis is warranted for population and species differentiation in the future.
Highlights
In order to develop the industry and extend land use towards the ocean, the use of limited land, large-scale land reclamation was carried out in wetlands along the western coast of Taiwan [1]
The present study identified E. cf. gilli inhabiting a wetland near the industrial park and hiding in mud shrimp burrows
The present results suggest that the dispersal and biogeographical distribution of E. cf. gilli are caused by the water mass transport of the China Coastal Current (CCC), which continues towards Hong Kong and Vietnam
Summary
In order to develop the industry and extend land use towards the ocean, the use of limited land, large-scale land reclamation was carried out in wetlands along the western coast of Taiwan [1]. The funders had no role in study design, data collection and analysis, decision to publish, or preparation of the manuscript
