[2] The native range of the Tridentiger bifasciatus is fresh and brackish water habitats in Asia.

[2] The Shimofuri goby is still distributed in its native Asian estuaries which include China, South Korea, Japan, and Russia.

This marsh is the largest brackish, mixture of salt and fresh body of water on the west coast.

This bay is known for its international cargo ship ports, which is thought to be the reason for the high level of non-native species throughout the connecting bodies of water.

The gobies spread from the Suisun Marsh into the connecting Sacramento-San Joaquin Delta which then provided the path into the aqueducts of the California State Water Project in 1993.

[4] The CSWP accesses multiple lakes and reservoirs where the Shimofuri goby has been detected until the present day.

[2] This large range of temperature and salinity resilience allows the Shimofuri goby to compete with native species in the San Francisco Estuary.

However, there has not been continued monitoring to further comprehend the ecological role that the introduction of shimofuri goby has on their new environment.

This native goby is a main food source of shorebirds, the southern steelhead trout, and the California habitat.
