Length‐Weight Relationships of Sixteen Fish Species From the Upper Tietê Basin, Southeaster Brazil
Journal of Applied Ichthyology, Volume 2025, Issue 1, 2025.This study investigated the length‐weight relationship (LWR) of 16 fish species from the Upper Tietê Basin under the influence of the Atlantic Forest biome, aiming to provide updated morphometric data and contribute to the knowledge of Neotropical ichthyofauna. 2811 specimens were collected and distributed across five orders and 10 families.
