The Transformation

Batbitim 2005
Active shark finning camp on beach
Blast fishing: destroying reefs weekly
Cyanide fishing: poisoning coral
Industrial longliners: depleting stocks
Villages paid: $30/month by finners
Same Waters 2024
Sharks: counts up about 190% inside and 560% outside since 2012
Fish biomass: up 29% since 2007
Manta rays: about 1,730 recorded, doubled in 10 years
Patrols: 1,150 in 2023
Rangers: 18 full-time
Illegal boats intercepted: 73 in 2023

The Radical Solution

2005: Andrew and Marit Miners, diving in Raja Ampat's remote waters, discovered paradise underwater and horror on the beach - an active shark finning camp on Batbitim Island. The contrast was stark: the world's richest reefs below, a graveyard of shark carcasses above.

The Lease Agreement
The Miners approached local communities who held traditional rights to these waters. Their proposal: lease the island and surrounding seas to create a no-take zone. The villages had been receiving just $30 per month from shark finners who took everything they wanted. The lease would provide steady income, jobs, and protect their ancestral waters.

With meager funds - they began construction in 2005. No experience in conservation, architecture, or island politics. Just determination. They set up a sawmill, milled 600 cubic meters of reclaimed driftwood, and recruited workers from nearby villages.

The shark finners were given notice through the lease agreement. They left. No protest. The villages had spoken through their traditional rights.

Working With the Government
The reserve covers about 1,220 square kilometers (465 square miles) of no-take waters inside Raja Ampat's zoning system. The private lease with the villages, begun in 2005, works alongside government zoning and a ranger partnership with the Raja Ampat Marine Park Authority. It is a co-managed model: protection through economics, with enforcement as a partner.
Then: Shark finners paid villages $30/month for unlimited extraction
Now: local jobs, donor-funded patrols, and fish biomass up 29% since 2007

From Destroyers to Protectors

The Rangers
18 full-time rangers, many former shark finners, patrol 1,220 km². Operating from 3 ranger stations with 5 patrol boats, they conducted 1,150 patrols in 2023 and intercepted 73 illegal fishing boats. 24/7 surveillance using radar, drones, and satellite monitoring.
The Economics
The Misool Foundation's total expenses were about $464,000 in 2023 (all programs, with ranger patrols about $97,000), funded by donors, grants and resort funds. The Raja Ampat Marine Park Authority is among the donors, and the Marine Police support patrols. Funding is not guaranteed, so protection depends on continued support.
The Recovery
The Misool Foundation reports that fish biomass inside the reserve rose an average of 248% between 2007 and 2021, then fell 44% by 2023. It is still 29% above 2007 levels. Recovery is real, but it is not a straight line. Ahmadia et al. (2015) describe how reserve effects are monitored across Raja Ampat's protected areas.

A Shared Effort

Misool's rangers work in partnership with the Raja Ampat Marine Park Authority and the Marine Police, with funding from donors, grants and resort revenue.

Measured Impact

Fish biomass inside the Misool reserve rose an average of 248% between 2007 and 2021, then fell 44% between 2021 and 2023, leaving it 29% above 2007 levels. Baited video surveys show shark numbers up about 190% inside the reserve and about 560% outside since 2012, from a very low starting point outside. In 2012, sharks were roughly 20 to 28 times more abundant in the no-take zones than in nearby open waters.

They didn't fight the shark finners.
They made them irrelevant through economics.

A beach covered in shark carcasses is now home to baby sharks in the shallows. Former shark finners patrol waters they once plundered. Not through enforcement alone, but through agreements with communities who hold traditional rights to their ancestral seas.

The Misool model proves protection works: secure community rights, provide economic alternatives, hire local guardians, maintain absolute protection. No compromises, no partial measures, no fishing at all. Complete protection, backed by steady donor support.

Fish biomass up 29% since 2007, after a sharp dip. Sharks far more abundant inside the closed zones than outside, with survey counts up since 2012. Dozens of illegal boats turned back each year. All from a lease agreement and the courage to say: these waters are closed. When extraction ends, life returns - and economics follow.
