Great Salt Lake Artemia

What Great Salt Lake Artemia does

Great Salt Lake Artemia (GSLA) is a privately-held, cooperative-structured supplier of premium Artemia (brine shrimp) products headquartered in Ogden, Utah. The company harvests Artemia cysts exclusively from the Great Salt Lake, which accounts for more than 45% of global brine shrimp egg supply, and exports to aquaculture hatcheries across 55+ countries. GSLA operates through multiple sub-brands (Sanders, Mackay Marine, Golden West, Aquafauna Bio-Marine, Ocean Aquaculture) and complements its core cyst business with a full portfolio of formulated hatchery feeds (Mackay Marine PEM diets, Brine Shrimp Flake, Algamac enrichment) and broodstock diets (Madmac-MS, Fortuna Broodstock+, frozen Artemia biomass, frozen squid).

The company's product platform rests on two proprietary processing technologies: SEP-Art, a magnetic separation technology that delivers 100% nauplii separation without chemical additives, and Artemia Guard, a biosecurity treatment that reduces Vibrio contamination in cysts. In May 2023, GSLA's fishery became the first inland U.S. fishery to achieve Marine Stewardship Council sustainable fishery certification, and the brine shrimp was designated Utah's state crustacean in March 2023, reinforcing its sustainability positioning.

GSLA's commercial model is direct B2B sales to commercial shrimp and fish hatcheries worldwide, supplemented by regional distributor partnerships (notably Prilabsa in Brazil) and active participation in major aquaculture trade shows across the Americas, Europe, and Asia. Pricing is quote-based with multi-year contracts; revenue is not publicly disclosed. In July 2025, GSLA expanded its platform by acquiring Ocean Nutrition Europe (Belgium) and Marine Nutrition Thailand from Torqx Capital Partners, adding premium feed manufacturing capacity and entry into the ornamental fish segment.

Direct peers

• INVE Aquaculture: Benchmark Holdings-owned aquaculture hatchery nutrition specialist selling Artemia, enrichment diets, and health products to global shrimp and finfish hatcheries. INVE is GSLA's most direct global competitor in Artemia cysts and hatchery feeds, serving overlapping customers through similar distribution channels.
• Brine Shrimp Direct: US-based supplier of Artemia cysts, decapsulated eggs, and specialty feeds primarily to the aquarium, ornamental, and small-scale aquaculture markets. Brine Shrimp Direct is a smaller direct competitor to GSLA's Artemia cyst business with overlapping end-customers.
• Aquafauna Bio-Marine: Artemia cyst and hatchery feed brand historically positioned as a premium global supplier to aquaculture hatcheries. Aquafauna Bio-Marine is now listed as a GSLA sub-brand, but the historical identity and product overlap make it a directly comparable peer in the Artemia category.
• Zeigler Bros: US-based specialty aquaculture feed manufacturer producing hatchery, shrimp, and ornamental fish diets. Zeigler directly overlaps with GSLA's Mackay Marine hatchery diet and broodstock diet lines and serves similar North American and export hatchery customers.

Broad incumbents

• BioMar: Global aquaculture feed manufacturer with hatchery, grower, and functional diets for salmon, shrimp, and other species. BioMar competes with GSLA in formulated hatchery feeds and enrichment products and serves overlapping shrimp and finfish hatchery customers.
• Cargill Aqua Nutrition: Aquaculture division of Cargill offering feeds and nutrition solutions across shrimp and finfish globally. As a broad incumbent with scale advantages, it competes with GSLA's hatchery and broodstock diet lines for the same enterprise hatchery customers.
• Skretting: Nutreco subsidiary and one of the world's largest aquaculture feed producers, with a portfolio spanning hatchery, grower, and broodstock feeds for shrimp and multiple finfish species. Skretting competes with GSLA in hatchery and broodstock diets and serves the same global aquaculture customer base.
• Charoen Pokphand Foods (CPF): Thailand-based integrated aquaculture producer with its own feed manufacturing, hatchery, and farming operations across shrimp and finfish. CPF operates in adjacent layers of the aquaculture value chain and is a large customer and competitor for hatchery nutrition inputs in Southeast Asia.
• Alltech: Global animal nutrition company with an aquaculture portfolio covering feed additives, premixes, and specialty nutrition for shrimp and finfish. Alltech competes with GSLA in hatchery and broodstock nutrition and targets similar aquaculture producers worldwide.

Regional players

• Avanti Feeds: India's largest shrimp feed manufacturer, producing feeds for vannamei and monodon shrimp. While primarily regional to India and focused on grower feeds rather than hatchery Artemia, Avanti is a comparable aquaculture nutrition platform that competes for adjacent wallet share of GSLA's Indian and Asian customers.
