Fish Species in Mexico's Lakes: Complete Guide

Main Species in Mexican Reservoirs

Mexican reservoirs harbor a variety of species offering excellent sport fishing opportunities. Here are the most important ones.

Largemouth Bass

The undisputed star of Mexican reservoirs. Micropterus salmoides was introduced to Mexico in the mid-20th century and found ideal conditions.

• Average weight in Mexican reservoirs: 3-8 lbs

Best Lakes

El Salto, Comedero, Baccarac, Vicente Guerrero, Huites

Primary Technique

Crankbaits mimicking juvenile tilapia. Natural color with white belly.

Tilapia

Tilapia isn't just a forage fish — it's the engine of the ecosystem in Mexican reservoirs. Without tilapia, there would be no trophy bass.

Importance
