What RoffaReefs does
RoffaReefs is a Rotterdam-headquartered marine aquaculture startup founded in 2021 by Sander van Lopik, a former aquarist at Rotterdam Zoo. The company develops two complementary products aimed at reducing pressure on wild coral reefs and improving sustainability in the public and private aquarium sector. Its flagship hardware is a solar-powered floating breeding system designed to rear marine fish larvae both inside aquaria and in open water; the system floats on top of source tanks to eliminate temperature differential stress on larvae and avoid separate heating or cooling. Its flagship consumable is a 100% aquacultured vegan fish feed formulated solely from seaweed and other algae, bound with agar rather than animal-derived gelatine, and intended for herbivorous marine fish such as surgeonfish. The feed is paired with 3D-printed bioplastic feeding racks (made from corn starch and seaweed-based bioplastic) that allow grazing fish to feed in a naturalistic manner.
The business model is in pilot stage. RoffaReefs is funded primarily by a grant from WWF-NL's Innovation Fund (used to support the Bonaire field pilot as part of WWF-NL's Dutch Caribbean Marine Strategy), with no disclosed venture capital or revenue. Reported revenue streams in the source material describe hardware sales or leasing of the breeding system to public aquariums and zoos and one-time licence-style supply of vegan fish feed products, but pricing is not publicly disclosed and no paying enterprise customers are named. Go-to-market combines a sales-led motion targeting European public aquariums and zoos (with pilots at Rotterdam Zoo, and planned sites in the Netherlands and France) and a community-led motion engaging the hobbyist aquarist community through social channels and content. Operational footprint extends to a Bonaire pilot site at the Sand Dollar reef (Kralendijk) in collaboration with Dive Friends and STINAPA, while research collaboration with the University of Delft supports aquaculture system improvements.
The company's primary problem set addresses is the dependency of public and private aquariums on wild-caught reef fish, the lack of sustainable herbivorous fish feeds free of fish meal and agricultural inputs, and the absence of reproducible marine fish breeding protocols. Two named institutional counterparts are Rotterdam Zoo (founding host and feed development partner) and STINAPA (Bonaire pilot advisor); additional named partners include WWF-NL, Dive Friends Bonaire, University of Delft, Burgers' Zoo and BlueLinked. With a 5-person founder-led team, no disclosed revenue, and no patents or certifications on record, RoffaReefs is an early-stage, pre-commercial venture whose strategic positioning is anchored in conservation partnerships rather than scaled customer revenue.

RoffaReefs product offering
Product offeringCore offering
RoffaReefs designs and sells sustainable marine aquaculture equipment and feed, including a solar-powered floating breeding system for marine fish larvae, a 100% plant-based vegan fish feed, and 3D-printed bioplastic feeding racks. Offerings target public aquaria, zoos, coral reef restoration projects, and aquarium hobbyists seeking low-impact, vegan-input marine fish husbandry solutions.
Product overview
RoffaReefs offers a portfolio of products focused on marine fish breeding and sustainable feeding for coral reef conservation. The core offerings include the Floating Breeding System (a solar-powered device for breeding marine larvae in aquaria and open waters) and Vegan Fish Feed (a 100% aquacultured, plant-based feed for herbivorous fish). The 3D Feeding Racks serve as an accessory module for the fish feed system, enabling natural grazing behavior. The Bonaire Pilot Program represents field deployment of the breeding system technology, conducted in partnership with WWF-NL and local organizations to test and improve the system in real reef environments.

RoffaReefs competitors and assessment
Company assessmentBroad incumbents
- Cargill Aqua Nutrition: Cargill's animal nutrition business includes one of the largest aquaculture feed portfolios globally. It is a broad incumbent in the same category RoffaReefs competes in, with the scale to rapidly develop competing algae-based formulations if the vegan marine feed market expands.
- BioMar: BioMar is a major aquaculture feed manufacturer with product lines for salmon, trout, and increasingly marine species. It is a broad incumbent peer in the aquaculture feed space, with sustainability positioning that could overlap with RoffaReefs' vegan feed narrative.
- Skretting (Nutreco): Skretting is the global leader in aquaculture feed, producing feeds for salmon, shrimp, and marine fish across more than 40 countries. It is a broad incumbent in the same feed category RoffaReefs is entering, with vastly greater R&D and distribution capacity.
Direct peers
- Sustainable Aquatics: Sustainable Aquatics breeds a wide range of marine ornamentals including tangs and angelfish, with a focus on captive-bred, sustainably raised fish. Peer to RoffaReefs in the marine fish breeding category, although they operate commercial aquaculture facilities rather than floating wild systems.
- Bali Aquarich: Bali Aquarich is a leading captive breeder of marine ornamental fish including angelfish, tangs, and clownfish. Peer to RoffaReefs in marine fish breeding for the aquarium trade, but does not develop novel feeding or breeding hardware.
- Oceans, Reefs and Aquariums (ORA): ORA is one of the largest commercial marine fish breeding operations in the world, producing captive-bred clownfish, gobies, and other reef species for the aquarium trade. RoffaReefs competes on the same core capability — captive breeding of marine reef fish — but differentiates through an open-water/solar-powered system and a complementary feed product.
Emerging players
- Coral Vita: Coral Vita operates commercial coral reef restoration farms using land-based methodology. Peer to RoffaReefs in the reef restoration economy, although it focuses on coral propagation rather than reef fish breeding — the two halves of the integrated reef restoration stack both companies are pursuing.
- Veramaris: Veramaris produces algae-based omega-3 fatty acids for aquaculture feed, used to replace fish oil in salmon and shrimp diets. Comparable to RoffaReefs' vegan fish feed thesis (eliminating fish meal via algae-derived inputs), but focused on salmon and shrimp rather than marine ornamentals.
- SECORE International: SECORE develops coral restoration techniques including larval propagation and works on reef ecosystem recovery. Comparable to RoffaReefs as a reef restoration technology developer, with complementary expertise on the coral side rather than the fish side of recovery.
- Rising Tide Conservation: Rising Tide Conservation is a non-profit focused on advancing captive breeding of marine ornamentals to reduce wild collection. Operates in the same conservation-driven marine breeding mission as RoffaReefs, but without commercial hardware or feed products.
