The life-history traits of a non-native population of Shimofuri goby (Tridentiger bifasciatus) were investigated in Nansi Lake, which is a storage lake on the East Route of the South-to-North Water Transfer Project, China. The results were analyzed in combination with data from other non-native populations of this species to reveal the life-history traits that caused its successful invasions. Mature gonads in April and May suggest that the species spawns in this period, and cohort tracking and age analysis revealed that individuals had a one-year lifespan. The relative fecundity was 2,825 ± 614 eggs/g. A short lifespan and high fecundity are …
