OUR SERVICES

Scientific expertise and skills for diverse projects

  • Specialized diving services to support advanced marine research including deep decompression dives, logistically challenging field locations, low visibility, task-oriented and specific scientific data collection dives. Team includes AAUS scientific divers and IANTD closed circuit rebreather diver, with over 40 years combined diving experience.

  • Planning and implementation of fish community and benthic composition surveys to monitor long-term and short-term biodiversity in marine habitats. 

  • Deployment of specialized equipment in marine habitats such as hydrophones and ADCPs, including site selection and logistics of long-term data collection needs for specific project objectives.

  • Handling planning, logistics, dive team management, implementation of a diverse array of marine research projects including hydroacoustics, fish tagging, biodiversity assessments and more. 

  • Knowledgable and experienced team to assist field implementation of coral reef restoration methods, including fragment collection, transport and outplanting.

  • Over 10 years of experience in training field techniques such as fish identification and community surveys, benthic characterization and analysis, coral reef restoration monitoring and specific scientific diving skills including AAUS-specific needs.

  • Non-field projects such as meta-analyses and reviews requiring extensive literature research and evaluation, generally management and policy focused.

Nassau Grouper Recovery

Monitoring the only known spawning aggregations of Nassau grouper and identifying critical habitat used by the species throughout ontogeny.

Coral Reef Restoration

We collaborate with HJR Reefscaping to actively outplant corals on multiple reefs along the west and south coasts.

Marine Debris

Isla Mar is actively involved in significant environmental initiatives aimed at reducing marine debris around Puerto Rico.

Fisheries Monitoring

We have dedicated ourselves to monitoring commercially significant groupers and snappers through innovative and consistent fisheries research.

Feeding Ecology

We use advanced next-generation sequencing to analyze fish gut contents, providing insights into their feeding ecology.

Marine Protected Areas

We are dedicated to helping marine protected areas achieve their goals through effectiveness assessments, site evaluations, and standardized biological data to inform management.

Mesophotic Coral Ecosystems

We explore deep coral reef ecosystems (> 30m) to characterize fish communities and document differences in this ecosystem compared to shallow water coral reefs.

Island Sciences

We are seeking new collaborations to advance our Ridges to Reefs initiative, aimed at exploring and understanding the complexities of science.

Finding Fish: the Search for Fish Spawning Aggregations (español)

Finding Fish: the Search for Fish Spawning Aggregations (español)
(subtítulos en español) As we fly over the beautiful coast of Puerto Rico, we are immersed in the views of fishing boats and fishers before plunging underwater and being surrounded by a very special fish, the Nassau grouper. This species, along with some other groupers and snappers, forms large aggregations during specific times of the year for the purpose of reproduction. Since these fish spawning aggregations (FSAs) occur annually at the same place and same time, they become easy targets for fishing which has driven some of these aggregations to extinction. Thus, regulations have been created to reduce fishing pressure during this critical life history stage, but finding these aggregations is not always an easy task. This video highlights the three-year project led by the scientific team of Isla Mar Research Expeditions and the University of Puerto Rico, Mayaguez as they search for FSAs using environmental DNA sampling and traditional ecological knowledge with the help from local fishers. Dive in alongside the team as they show us the intensity of searching for these ephemeral fish aggregations and learn something new about this incredible technique known as environmental DNA sampling. Funding for this video was provided through the NOAA Saltonstall-Kennedy Grant Program.

Artedi : For the Modern Ichthyologist
This documentary highlights our web app, Artedi, and the experiment we conducted in collaboration with the University of Puerto Rico, Mayaguez Dept. of Marine Sciences to test the efficacy of the application at teaching fish identification. Check out the app at www.artediapp.com . The project was funded by an Applied Research grant from Puerto Rico Sea Grant.

Ciencia Ciudadana | Para la Naturaleza
In this video, we describe our Citizen Science project that we established with colleagues at HJR Reefscaping for Para la Naturaleza's Hacienda la Esperanza in Manati. We discuss the project and how we involved citizens in this coral reef fish monitoring program.
