The biodiversity of fishes at the Islas Marías Biosphere Reserve, Mexico, as determined by baited remote underwater video

The Islas Marías Biosphere Reserve, made up of 4 islands in Pacific waters off central Mexico, supports a large diversity of marine life. However, scientific research was restricted for decades by the occupation of Isla María Madre by the Federal Penitentiary Colony of Mexico from 1905 to 2019. Asid...

description The Islas Marías Biosphere Reserve, made up of 4 islands in Pacific waters off central Mexico, supports a large diversity of marine life. However, scientific research was restricted for decades by the occupation of Isla María Madre by the Federal Penitentiary Colony of Mexico from 1905 to 2019. Aside from a list of coastal fish species published in 2011, little has been published about the fish biodiversity in the area. While the limited access to the archipelago may have acted as a de-facto marine reserve, there is evidence that fishing continued both legally for the benefit of the colony and illegally by trespassing vessels. In order to establish baseline ecological data for future conservation planning, we used baited remote underwater video (BRUV) surveys at all 4 islands during 3 expeditions to the archipelago in 2018. A total of 131 BRUV surveys representing ~150 h of footage were analyzed to create the most current compilation of species and abundance data on coastal marine fishes at Islas Marías. Ninety-nine species were identified, 3 of which were additions to the previous assessment. We found strong separation of fish communities based on both habitat and depth, and an association between hard-bottom habitats and high biodiversity of reef fishes. With the declaration of Islas Marías as a natural reserve and relocation of the prison in 2019, there is an opportunity for the reserve to become a priority area for marine conservation on the Pacific coast of Mexico. Spatial analyses of fish biodiversity at Isla María Cleofas can help develop sustainable management strategies at a time when the governmental jurisdiction of the iconic archipelago is uncertain.

La Reserva de la Biosfera Islas Marías, compuesta por 4 islas en aguas del Pacífico frente a la costa central mexicana, sustenta una gran diversidad de vida marina. Sin embargo, la investigación científica ha sido restringida durante décadas por la presencia de la colonia penal federal en isla María Madre desde 1905 hasta 2019. Además de una lista de especies de peces costeros publicada en 2011, se ha publicado poco sobre la biodiversidad de peces en el área. Si bien el acceso limitado al archipiélago pudo haber creado una reserva marina de facto, hay evidencia de que la pesca continuó, tanto legalmente para el beneficio de la colonia, como ilegalmente por embarcaciones externas. Con el fin de establecer datos ecológicos de referencia para futuros planes de conservación, en 2018 realizamos monitoreos mediante el uso de video subacuático remoto con carnada (BRUV, por sus siglas en inglés) durante 3 expediciones a las 4 islas. Las imágenes resultantes de 131 monitoreos con el sistema BRUV (~150 h) se analizaron para compilar una lista actualizada de especies y datos de abundancia de peces marinos costeros en islas Marías. Se identificaron 99 especies, 3 de las cuales fueron complementarias a la evaluación previa. Los resultados mostraron una fuerte separación de la comunidad de peces con base en el tipo de hábitat y la profundidad, así como una asociación entre hábitats de fondo duro y la alta diversidad de peces arrecifales. Con el decreto de islas Marías como reserva natural y la reubicación de la prisión en 2019, existe la oportunidad de que la reserva se convierta en un área prioritaria para la conservación marina en la costa mexicana del Pacífico. Los análisis espaciales de la biodiversidad en isla María Cleofas pueden ayudar en el desarrollo de estrategias de manejo sustentable ante la presente incertidumbre de jurisdicción gubernamental en este icónico archipiélago.
