Join our ‘REEF SUPPORT CREW’ — Dive with purpose to help monitor key reef fish and contribute to real marine conservation.
Help survey commercial fish species, record sightings in the Verde Island Passage. This Reef Support Crew dive experience supports local marine protection efforts by turning diver observations into data that helps fisheries management and protect reef ecosystems where it matters most.

Many reef fish populations in the Verde Island Passage are under pressure, but data remains limited — By helping collect credible scientific observations, your participation provides the evidence needed to guide sustainable fishing and protect vital reef species — FinVentory supports Blue Alliance Philippines, co-manager of Marine Protected Areas along North Mindoro’s coastline.

FinVentory is our Reef Support Crew version of a fish survey—designed for everyday divers who want to contribute to real marine conservation.
Based on a method used by scientists worldwide, it involves swimming along a set line on the reef (a transect) and recording the fish seen within a defined area. Each dive adds to a growing dataset used to monitor how fish communities change over time.
Our focus for FinVentory is commercial fish—species like snappers, parrotfish, grunts, wrasse, triggerfish and more, that are commonly caught by small-scale fishers and sold in local markets.
These fish are vital to food security and coastal livelihoods, and they also reflect the overall health of a reef. A healthy population means balanced fishing pressure; a decline can indicate overfishing or habitat stress.
By tracking these species, FinVentory helps marine managers make informed decisions to protect both reef ecosystems and the communities that depend on them.
Measuring out transects
Confirming fish ID with our Reef Support Crew
Each FinVentory dive follows a simple method called an underwater visual census.
Before diving, participants are briefed on how the survey works and introduced to the key commercial fish species they’ll be monitoring. Divers receive waterproof slates with ID photos to help with recognition underwater.
At the site, our Reef Support Crew lays transect line along the reef. Divers then swim slowly along this line, observing within a set field of view, and record on their slates, the species they see, how many of each, and a rough size estimate.
It’s not about identifying every fish or being perfect—just making careful, consistent observations. Our Reef Support Crew is always nearby in the water to help with species ID, sizing, support, and guidance.
The data collected goes into a long-term monitoring programme led by Blue Alliance Philippines, used to assess reef health, guide conservation efforts, and inform sustainable fishing policies.
It’s real science with impact—and 100% of Coral Reef Safari profits go back into marine protection.
As part of the Reef Support Crew, you’re more than just a diver—you’re a field assistant helping to gather real data that informs conservation decisions.
What to Expect:
Morning check-in, gear sizing, and FinVentory briefing
Land-based training in survey methods and fish ID
First dive: conduct a full survey along a set transect
Lunch break onboard or on a nearby beach
Second dive at a different reef site
Afternoon data review and interpretive debrief
Receive a certificate of contribution, and later, a post-trip report
Every fish you record helps build a clearer picture of reef health and supports long-term protection of the species—and the communities—that rely on it.
