MAR Fish Project: Knowledge, Monitoring and Protection of Mesoamerican Reef’s Fish Spawning Aggregations

Introduction

The MAR Fish initiative is the latest and largest coordinated monitoring network of fish spawning aggregation sites (FSA) in the Mesoamerican Reef region (MAR). This project is possible thanks to the generous funding from the French Global Environment Facility (FFEM in French), also by the Summit Foundation, Marisla Foundation and Oceans 5. The activities of the project are implemented thanks to the collective effort of partner organizations in the four MAR countries.

Participating organizations

The MAR Fish Project is coordinated by MAR Fund, a private regional environmental fund. The implementation of the project is carried out with the participation of the following eight core partners:

  • Comunidad y Biodiversidad, COBI
  • Coral Reef Alliance, CORAL
  • Healthy Reefs for Healthy People Initiative, HRI
  • Fundación para el Ecodesarrollo y la Conservación, FUNDAECO
  • Southern Environmental Association, SEA
  • Toledo Institute for Development and Environment, TIDE
  • Rotary International
  • Environmental Defense Fund, EDF

What are fish spawning aggregations?

Fish spawning aggregations are temporary gatherings of fish that come together for reproduction purposes, these aggregations are critical for the survival of the species and extremely vulnerable to fishing. FSA generally represent the near total annual reproductive output of the species that spawn there. Periodic information on FSA health, critical for their protection, is missing and there is no cohesive, multinational plan to monitor and manage them, nor widespread understanding of their importance.

Seven sentinel sites were defined for the network of FSAs of the MAR Fish Project. Two additional sites, one in Belize and one in Honduras, were selected by each country to be included in the monitoring FSA network. The FSA monitoring will contribute to the understanding of the connectivity and the health of the MAR ecosystem for the restoration of fish stocks; and provide information on the impact of climate change on the spawning aggregation sites, to the benefit of fisheries and the communities that depend on them.

Fish spawning aggregations of the network of sentinel sites

A total of nine sites were selected for monitoring, five of which are sponsored by FFEM, two by the Summit Foundation, and two by COBI.

FSA Sentinel Site Country
Niche Habin (Punta Allen) Mexico
El Faro (Punta Herrero) Mexico
Gladden Spit Belize
Emily (Caye Glory) Belize
Cayman Crown Belize
Cayman Crown Guatemala
Western Bank (Texas – West End) Honduras
Cordelia Banks Honduras
Power Point (Lawson Rock-Sandy Bay) Honduras

Objectives

General Objective
The overall objective of this three-year project is to promote the recovery of fisheries by strengthening the protection of the FSAs of commercial fish, as critical areas in the life cycle of the species, through better knowledge and understanding of the aggregations in the region.

Specific Objectives
The project will achieve two specific objectives:

  1. Obtain legal recognition and adequately manage Cayman Crown in Guatemala and Belize.
  2. Promote participatory monitoring of a network of sentinel spawning aggregation sites in the four Mesoamerican Reef countries.

Project structure

The Project has four components with specific activities that are being developed by the partner members through signed agreements with MAR Fund.

  • COMPONENT 1: The Cayman Crown Reef is legally recognized and managed in Belize and Guatemala
  • COMPONENT 2: Sentinel Site Observation Network
  • COMPONENT 3: Fostering the social acceptability and support for protecting spawning aggregations
  • COMPONENT 4: Project Management.
