Cabo Verde

The status of sharks and rays in the Eastern Atlantic is poorly known, as is their connectivity with the Western Atlantic. Working with traditional fishers and institutional partners, we are conducting the first fisheries-dependent and independent assessments and long-term monitoring of sharks and rays in Cabo Verde, including critical nursery areas. This work gives us […]

Federated States of Micronesia

Sharks’ potential reliance on grouper spawning aggregations for sustenance and how this may impact fisheries and marine protected areas management form the focus of our first project in Pohnpei, the capital state of the FSM. We are also investigating the spatio-temporal behaviour of coastal manta rays around the islands and their capture vulnerabilities to the […]

USA

Manta rays are frequent visitors to the Gulf of Mexico’s Flower Garden Banks National Marine Sanctuary.

Panama

Panama is bounded by the Caribbean and the Pacific yet scarce information exists on the status of its sharks and rays. Panama is also host to one of the remnant populations of critically endangered largetooth sawfish. MarAlliance is conducting fisheries-dependent and independent monitoring of fish and working to protect sawfish throughout the country. We conduct […]

Mexico

The Caribbean facing state of Quintana Roo possesses over 500 km of the MesoAmerican Reef and hosts key aggregation sites for several megafauna including whale sharks, manta rays and reef sharks. We have established permanent sites where we conduct standardized long-term monitoring of coastal and reef-associated marine megafauna.

Honduras

A moratorium on fishing sharks declared in 2011 has left the country without much data on populations and distributions of sharks and rays (collectively known as elasmobranchs). Working locally with traditional fishers, coastal and indigenous communities, we focus on generating information necessary for management and decision-making through collaborative research and monitoring, capacity building, income diversification, […]

Belize

With 24 years of country-based experience working with large fish, turtles, fisheries, and the tourism sector in Belize, MarAlliance’s work with large iconic marine wildlife began here. Our multi-pronged approach to big fish conservation integrates fisheries-dependent and independent research, tourism, outreach and education, capacity building, and policy support.

Baseline BRUV Surveys, Eastern Cabo Verde

We have monitored marine megafauna in Eastern Cabo Verde around the islands of Boavista, Maio and Sal since 2015. Working with traditional fishers and students we use baited remote under video (BRUV) deployed systematically around the islands based on a spokes-on-a-wheel design, that generated a baseline of abundance and distribution of sharks, rays and large […]

Lighthouse Reef Atoll – Belize

MarAlliance has been conducting research at Lighthouse Reef Atoll on an annual basis since 2007. We use scientific longline, Baited Remote Underwater Video (BRUV), and snorkel underwater visual census (UVC) to analyze long-term trends in the abundance of sharks, rays, turtles, and large finfish. We work in partnership with local fishers, university students, and other […]
