Improved hatching procedures, better feed management, and water quality monitoring are examples of innovations that can increase yields and lower losses. These strategies bolster provincial food security and assist farmers.
Although aquaculture has achieved significant progress in terms of efficiency and scale, its further expansion is nevertheless dependent on inputs that are becoming more unpredictable, resource-constrained, and vulnerable to environmental hazards.
Over half of the fish consumed worldwide today comes from aquaculture, and this percentage keeps rising. This is important for nutrition, livelihoods, and food security. However, it also strains a feed system that is mostly dependent on fishmeal, fish oil, and soy—all of which are linked to limited resources, unstable climates, and geopolitical unrest. The health of forage fisheries and uncontrollable price cycles are strongly linked to farmed seafood, as around 16 million tons of wild fish are still reduced into feed annually.
It has become evident to me that developing a more resilient and diverse feed system is critical to aquaculture’s capacity to grow. We’re witnessing the emergence of a number of complimentary innovation pathways that each target a distinct systemic pressure point, even while there isn’t a single solution that will propel the sector ahead. When combined, they offer a structural improvement to the procurement, preparation, and distribution of aquaculture feed.
Alternative Proteins & Oils
The search for next-gen aquafeed ingredients has pushed innovation well beyond traditional fishmeal and fish oil. New protein and oil sources are emerging that bypass land, water, and ecological pressures associated with conventional agriculture and wild fisheries. Insects, algae, and microbial proteins deliver essential nutrients while reducing dependence on volatile commodity markets.
Without depending on wild fisheries, Mara Renewables CORP, for example has demonstrated how algae fermentation can yield dependable omega-3 oils. Mara’s manufacture eliminated 6.7 billion anchovies from the global supply chain in 2024 alone. Another illustration is Enthos Circular Feed Technologies, Inc. c., which is expanding the production of Black Soldier Fly (BSF), which transforms food waste into premium feed ingredients. Up to 1,500 times more protein may be produced per hectare using BSF systems than soy, and Enthos’ flagship plant in Colombia is intended to grow into one of the biggest hubs for insect protein in Latin America. These commercial platforms show how aquaculture growth can be separated from limited marine inputs.
Circular Economy Feeds
A defining feature of the global food system is inefficiency, with more than 1.3 billion tons of food wasted each year. Circular economy feed solutions address this imbalance by capturing nutrient streams that would otherwise be discarded and converting them into aquaculture inputs. Byproducts from food processing, invasive species removal, and bioconversion are emerging as viable sources of feed-grade protein and oils.
Precision Nutrition
Feed represents the largest share of aquaculture operating costs, yet a meaningful portion is still wasted. Precision nutrition tools are tackling this inefficiency by aligning feed delivery with real-time fish appetite and growth needs. AI-driven cameras and sensors now allow farmers to monitor behavior continuously and adjust feeding dynamically.

For example, ReelData AI , a S2G portfolio company, is advancing this shift through AI-enabled monitoring and predictive analytics in land-based systems. Its platform uses machine learning and imaging to interpret appetite signals, measure biomass, and automate feeding in real time. The result is up to 25% feed waste reduction and 10–15% faster growth rates, alongside more predictable harvest cycles and lower operating risk.
Functional Feeds
Disease remains one of aquaculture’s most costly constraints, and reliance on antibiotics is increasingly untenable. Functional feeds offer a new paradigm: using nutrition to strengthen immunity and resilience. By incorporating bioactive compounds, these feeds shift aquaculture from reactive treatment toward prevention.
Kuehnle AgroSystems Inc. . produces natural astaxanthin via fermentation. Astaxanthin is a critical carotenoid in aquaculture feed, widely used to support pigmentation, immune function, stress tolerance, and reproductive performance. It is both a health ingredient and a commercial necessity, influencing product quality, animal resilience, and market value. Kuehnle’s fermentation-based process delivers 75% lower GHG emissions, 85% lower water use, and 98% lower land use than other natural astaxanthin sources used in aquaculture. Additionally, ViAqua Therapeutics Ltd. is advancing RNA-based feed solutions, with its first product targeting White Spot Syndrome Virus (WSSV), one of the most damaging pathogens in shrimp farming, responsible for billions in annual losses worldwide.
A Reimagined Future of Aquafeed
As aquaculture continues to scale, the demand for feed will rise sharply. Whether that demand supports global food security or drives further ecological strain depends on feed innovation.
Importantly, the economics align with the impact. Diversifying feed ingredients reduces exposure to volatile commodity markets. Smarter feeding improves margins while also improving water quality. Healthier fish grow more consistently, survive at higher rates, and produce more predictable yields. These gains accrue not only to farmers, but to coastal and rural economies that depend on stable aquaculture production, and ultimately to consumers who rely on seafood as an affordable, nutrient-dense source of protein.
Realizing this future will require coordination. Ingredient innovators must scale with discipline and consistency. Farmers and feed manufacturers must validate performance and commit to adoption through long-term partnerships. Regulators must provide clear, science-based pathways that recognize both safety and urgency. And investors have a role to play in backing proven platforms through the hard work of disciplined scale-up.
