The Hunt
A Responsible Pursuit in the Wilds of South America
Fishing for Arapaima in their natural habitats of South America offers a unique and thrilling experience, demanding a strong commitment to responsible tourism, ethical practices, and conservation.
This prehistoric giant, a symbol of the Amazon, has faced significant overfishing, making sustainable approaches critical for its survival.
Ecology & Behavior:
Diet: The Arapaima is a carnivorous and opportunistic predator in its natural Amazonian habitat. Its diet varies somewhat with its life stage and the availability of prey in its environment. They primarily eat fish, crustaceans, and insects (aquatic and terrestrial).
Arapaima are known to capture small land animals that venture too close to the water’s edge or fall in. This can include: small mammals, birds, and reptiles.
While the male is actively guarding the fry, the female typically circles in the vicinity, acting as a defender against potential predators. She usually leaves the family unit after about a month and often reproduces with other males in the same reproductive season.
Life Cycle, Size, and Growth Rates: Once out of the larval stage, he young fish grow incredibly fast. After 6 months, they are already 50cm in length, and within their first year, they can already reach an average length of 1m or more!
At about 5 years old, they are sexually mature and typically about 1.5m long. After reaching maturity, they continue to grow and a common adult size would be 2m in length and can weigh between 220- 330 lbs.
The largest recorded specimens have been over 3m long and weighed as much as 450 pounds!
Arapaima can live for over 20 years in the wild, though their populations face overfishing and other ecological threats that reduce this considerably.

Responsible Tourism & Ethical Practices
Engaging in Arapaima sport fishing should always prioritize the well-being of the fish and the local ecosystems. This means:
Essential for navigating the complex river systems and ensuring compliance with local regulations. These guides often possess invaluable traditional knowledge about the fish and its habitat.
Many successful Arapaima conservation efforts are driven by local and indigenous communities. Choosing operators that directly benefit these communities and their sustainable management programs (like those in Brazil’s Mamirauá Reserve or Peru’s Pacaya Samiria) contributes to conservation.
Adhering to eco-tourism principles means minimizing disturbance to wildlife and their habitats, respecting local cultures, and leaving no trace behind. This includes proper waste disposal and avoiding sensitive breeding areas.
Conservation Focus: Catch and Release, Size/Catch Limits
Conservation is paramount for the Arapaima, which are listed as endangered due to past overexploitation. Sport fishing is almost exclusively catch and release, with strict guidelines:
Catch and Release (C&R):
This is the mandatory practice in virtually all legitimate Arapaima sport fisheries. The goal is to minimize stress and injury to the fish, ensuring their survival post-release.
Best Practices:
Use barbless hooks and rigs to reduce gut-hooking; keep the fish in the water as much as possible; use proper support (e.g., cradle the fish with two hands under the belly and don’t lift too high) if briefly lifted for a photo; ensure the fish is fully revived before release.
Size and Catch Limits
While exact regulations vary by country and even by specific managed areas, the general principles are:
Minimum Size Limits: Common for commercial harvests, but in sport fishing, the focus is on releasing all fish regardless of size. Some managed areas might have a minimum size (e.g., 5 feet or 150 cm in Brazil’s Mamirauá) for harvest if allowed, but sport fishing is typically 100% C&R.
Catch Limits: Often, sport fishing operations have “zero retention” policies, meaning no fish can be removed from the water for harvest. Daily catch numbers may be informally tracked by lodges, but are not usually formal limits in the sense of keeping fish. The emphasis is on the experience, not the harvest.
Prohibitions: In some regions, like much of Brazil, fishing for wild Arapaima has been prohibited except in areas with community management agreements where sustainable quotas are set for local consumption and sometimes limited commercial sales.
Prime Fishing Locations & Countries
Arapaima are native to the Amazon basin and its tributaries. Prime fishing locations are found in countries committed to their conservation:
Considered a premier destination. The Mamirauá Sustainable Development Reserve in the state of Amazonas is world-renowned for its successful community-managed Arapaima fisheries, offering strictly controlled catch-and-release fly fishing. Other areas in the central Amazon may also offer opportunities. Fishing seasons often coincide with the dry season (July-December) when water levels drop, concentrating the fish.
Peru:The Loreto region, particularly areas like the Pacaya Samiria National Reserve and the Nanay River near Iquitos, is prominent. Peru promotes catch and release, and the dry season (June-November) is also optimal.
Guyana:Lesser-known but with strong conservation efforts, the Essequibo River and its tributaries offer excellent Arapaima fishing. The prime season here runs from September to February.
Colombia:The Caquetá and Guainía rivers, particularly around the Amazonian region near Leticia and the Yahuarcaca Lakes, offer opportunities, often integrated with local community conservation initiatives. The best months are typically July to October.
Indigenous Partnership
Fishing operations for Arapaima in South America are increasingly adopting models that partner directly with local indigenous communities.. This approach is not only ethical but also proven to be highly effective for conservation. It involves the co-management of resources and territory rights, joint conservation planning, and the monitoring and enforcement of rules and regulations.
Economic benefits of these partnerships are more than just from employment and jobs, but revenue share and training programs that all help to support the local community.
The authentic experiences that tourists have give them a deeper understanding of local culture, traditions, and the daily lives of the Amazonian people, which is enriching for both parties.
There are good examples of lodges and reserves in both Guyana and Peru, but the most famous is Mamirauá Reserve in Brazil. The communities here have exclusive rights to manage Arapaima in their areas. Fishing lodges, like Pirarucú, operate under strict agreements where a substantial portion of the lodge fees goes directly to the community associations, and all guides and lodge staff are also from the local communities. This has led to a remarkable recovery of Arapaima populations and significant improvements in community well-being.
