Location: Tahiti, French Polynesia
Date of creation: launched in 2012
Analysis by the association: January 2018
Producer of aquaponics systems.
In 2012, Teanuanua Teriipaia-Rentier, a young Polynesian with a degree in aquaculture, created his company, Rima Ninamu, specialized in the construction of aquaponic systems mainly for individuals, but also for project promoters and schools.
The main activity of the company is custom construction and installation of aquaponic systems, but it also focused for 5 years on the development of natural inputs to develop low cost production systems. Since 2017, the company also gives trainings to learn all the aquaponics¹ techniques. Thereafter, we will analyze the functioning of the aquaponic systems sold as well as the techniques and natural inputs developed by the company to make these systems optimal, economic and environmentally friendly (we will not analyze the company itself).
Natural inputs to fill the mineral deficiencies of plants :
Inputs manufacturing process:
Raw material origin:
Algae: available all over the year for free on the beaches of Tahiti. Algae are invasive species, so their use in aquaponics is beneficial for the environment.
Lombrics: imported from New Zealand, but as it is a species that breeds quickly, just import a small amount once
The plants and fish produced:
These systems allow to produce rather green plants, such as salads, Chinese cabbage and herbs. The most common fish are tilapias sunfish, one of the best robust species that reproduces easily. The newborns first pass through the nursery to grow and join the aquaponic system.
Fish are fed commercially purchased fish feed. Aquaponic systems are equipped with automatic feeders allowing feeding in the morning and evening. The quantity of food distributed depends on the mass of the fish, but still corresponds to 5% of their biomass.
Inputs to fight against diseases:
Each technique or input is used only in the prevention of diseases and pests, and are administered by foliar sprays.
The company also trains each client on the basics of aquaponics and the basics of using aquaponic systems. Trainings over several weeks are also provided by the company and open to all.
Aquaponics in Tahiti is done in a covered structure or in a greenhouse with a lot of ventilation because of the high temperatures. The system is reproducible as is for countries with the same climatic conditions.
Moreover, aquaponics is spreading over the world and is easily replicable anywhere!
The food used to feed the fish is the most costly in the operation of an aquaponic system, which is why Rima Ninamu leads R & D to develop its fly production as an alternative feed for fish. In July 2018, the company will launch its production of black soldier fly (Hermetias illuans) (with valorization of copra cake) to feed the fish of the aquaponic systems. It will also launch its own aquaponic farm on 200 m² in Pirae (Tahiti island). Finally, the company is also in the acquisition phase to launch a hatchery of mangrove crabs.
