“It isn’t about both/or, it’s all the above,” Kingfish Company CEO Ohad Maiman stated throughout a panel dialogue on scaling various aquafeed components on the current Animal AgTech Innovation Summit. The panel, which additionally featured trade leaders from Cargill, Aqua-Spark* and Deep Branch dived into the present manufacturing and funding panorama for sustainable aquafeed components.
Although the trade is coming nearer to producing a totally sustainable aquafeed, the panel agreed that eliminating typical marine components like fishmeal and fish oil is unlikely within the near-term. Sustainable aquafeed components will most likely complement typical feed components for the subsequent decade till they will scale manufacturing.
Aquafeed’s sustainability problem
The majority of aquaculture’s carbon footprint comes from aquafeed. Finfish and crustacean species have historically relied on protein-dense feed sources like fishmeal and soy to thrive – however aquafeeds can’t depend on these components for for much longer.
Aquaculture producers and feed corporations are at the moment on the lookout for new and sustainable components that would revolutionise the feed trade. The power to cut back and ultimately substitute marine components like fishmeal and fish oil with out sacrificing farm effectivity would make the sector extra sustainable. Some promising various feed components are getting into the market, however they will solely make a optimistic influence if they’re produced at scale.
The present panorama in sustainable aquafeed
Peter Rowe, CEO and co-founder of Deep Department defined that feed producers should front-load capital earlier than various aquafeeds might be commercialised. His startup produces proton, a single-cell protein (SCP) derived from CO2 that can be utilized as an aquafeed ingredient for Atlantic salmon.
Rowe stated that he needed to construct robust relationships on either side of the worth chain to validate Deep Department’s know-how and be sure that the bioprocesses have been properly executed. The CO2-based feed may very well be a sustainability game-changer – however scaling manufacturing to be value aggressive with typical feed components is the problem. In accordance with Aqua-Spark co-founder Mike Veilings, Rowe and different innovators in sustainable aquafeeds want traders with deep pockets and a long-term imaginative and prescient to make an influence.
Firms that produce and use sustainable feed components are additionally reliant on shoppers to take care of the sector’s momentum. For Ohad Maiman, shoppers who fall into the “early adopter” class are footing the invoice, as his yellowtail RAS firm progressively reduces marine components of their aquafeed in favour of extra sustainable choices. Rowe largely agrees – saying that courting early adopters is essential for an impactful product.
Maiman stated that his prospects are wanting past fish-in-fish-out (FIFO) measures in his feed technique. “We had inquiries on what it might take to supply yellowtail kingfish on one hundred pc various components,” he defined. However after operating the numbers, the corporate discovered that fully changing marine components could be prohibitively costly. “There have been no takers,” he advised the panel.
Nonetheless, Maiman and his colleagues discovered that they will considerably scale back marine components of their feed and complement it with sustainable alternate options with out impacting general productiveness. Although their yellowtail is offered at a premium, some shoppers weren’t discouraged. “[With] a mix of decreasing marine components, continually including sustainable ones and aspiring to that place the place it’s cost-effective to switch them is the most effective we will do at this level.”
Veilings thinks that sustainable aquafeeds might be used to complement typical protein components as a substitute of fully changing them. The supplementation technique will go a good distance in direction of enhancing aquaculture’s carbon footprint, however in his view, complete alternative of soy, fishmeal and fish oil will take a long time. A sustainable aquafeed revolution isn’t on the instant horizon.
The investor’s perspective
Talking as an investor, Veilings stated that sustainable feed corporations must concentrate on bringing prices down with the intention to scale up. They can not function at a premium value level eternally.
Many of those feed corporations produce protein sources from seaweeds, bugs and SCPs that need to be reduce with bulk components. This may work through the pilot stage, however startups must concentrate on being economically viable and creating standalone merchandise. If sustainable feed stays costly, then it also needs to supply aquaculture producers enhanced dietary options to justify the value premium.
Cecile Lassalle, formulation and price pricing director for Cargill Inc, advised delegates that sustainable aquafeed components have the potential to interrupt into different markets – serving to them scale and reduce prices.
She defined that most of the modern protein sources may very well be used to formulate livestock feed and pet meals. Each market segments are in a drive to cut back or substitute the quantity of soy, palm oil, fish oil and fish meal of their product portfolios. Improvements in sustainable aquafeed may very well be simply leveraged throughout three markets as a substitute of 1.
“Pet meals may very well be a better-paying market than aquafeed,” Lassalle stated.
Potential alternatives
When requested in regards to the trajectory of sustainable aquafeeds, Lasalle advised the panel that the trade should first determine what it needs to attain with various components. In her view, there are two main push elements that underpin the sustainable feed sector: the necessity to substitute marine components and the necessity to scale back carbon emissions general. Due to this, she is especially specializing in microalgae.
Lasalle says that the microalgae section is nearer to industrial scale than different various components. It will probably even have a optimistic local weather influence (seaweed naturally sequesters atmospheric carbon) and supply a supply of omega-3 fatty acids with out utilizing fish meal or fish oil. It is usually comparatively economical compared to different sustainable protein sources. Microalgae will kind a part of Cargill’s sustainability technique going ahead.

Lasalle additionally advised delegates that insect meal is on the cusp of scaling. Some insect-based aquafeeds are being produced, however the trade must construct capability earlier than taking off. She additionally spotlighted single-cell proteins and mycoproteins as promising feed components. Veilings agreed, telling delegates that Aqua-Spark expects so as to add mycoprotein fermentation to its funding portfolio within the close to future.
The long-term imaginative and prescient
Lasalle believes that aquafeed producers must conduct additional analysis on their merchandise. This can allow them to decide the optimum inclusion stage for sustainable feed components – and the quantity of marine components they will forgo with out sacrificing high quality metrics.
For Maiman, adopting sustainable aquafeed components received’t spell the tip of typical marine components. As an alternative, scaling sustainable feed sources will enhance aquaculture’s carbon footprint with out passing the bills to shoppers. “one hundred pc alternative isn’t the purpose,” he stated.
“If aquaculture goes to double, or probably triple by mid-century, we’re going to want over 200 million tonnes of additional components in comparison with the place we’re right this moment,” Veilings stated. It should take a long time of funding and a broad portfolio of components to construct that capability.
The Animal AgTech Innovation Summit was held between 19 and 20 October.
