Abstract

The paper presents an extensive fish sampling dataset spanning a long-term period (weekly) from 2010 to 2019. The data was collected in Lenta Marina, an upstream area in the Minho Estuary of the NW Iberian Peninsula. To capture fish, fyke nets were utilized as the sampling method. This dataset offers valuable insights into the abundance of each collected taxa, recorded per date.

The dataset reports a comprehensive compilation of fish abundance data, providing a detailed record of how the fish community has changed over time. The dataset clearly shows a trend where the amount of fish from invasive taxa exceeds the count of fish from native taxa.
