How sustainable insect protein feed is transforming global aquaculture, with 3x faster adoption in alternative feed solutions. When Norwegian salmon producers started making announcements that their goal would be cutting the use of fishmeal in half by 2030, it meant more than just another company taking on corporate sustainability. It signalled the point in time when the entire industry realised the need for re-evaluation of its very foundation. Insect protein is the unlikely solution in this process of re-evaluation.

Black soldier fly (BSF) larvae, mealworms, and even housefly maggots are not merely laboratory experiments anymore but commercially produced feed products. This transformation has happened quite rapidly. The Global Aquaculture Protein Market Research Report 2034 puts the current size of the worldwide aquaculture protein market at $12.4 billion, rising up to $22.8 billion within the decade at a CAGR of 7.0 percent. Among the rapidly growing segments, insect protein is making the biggest gains, with manufacturers using alternatives to fishmeal at three times the speed.

Why fish meal is becoming unpopular

The reason why fish meal is losing popularity is because it is an efficient feed with a high digestible protein content, contains all necessary amino acids, and has a natural attraction for carnivorous fish such as salmon and sea bass. The challenge with fish meal is its source, as it comes from fish caught from already stressed marine environments.

The global fish market saw global fish production reach up to 185 million metric tons with aquaculture responsible for producing 57% of the quantity and accounting for over 63% in the early 2030s. Production costs vary among farms with feed costs forming between 40% and 70% of the total cost incurred. With rising prices of fish meal following El Niño-related anchovy seasons in Peru, other options seem more economical.

The BSF larvae have crude protein levels ranging from 40% to 55%, with a good amino acid composition for the feeding of many kinds of farmed fish. The high level of lauric acid in these larvae gives them good antimicrobial characteristics; the chitin that they carry may improve gut functionality. Importantly, the BSF larvae are raised on organic waste products, such as those from food processing, brewing, and agriculture.

From pilot to commercial scale

Over most of the past decade, insect meal has been simply too costly to be competitive. High capital investments required to develop rearing facilities, along with complicated regulations, made investors wary. The situation is now different. The value of the black soldier fly market exceeded $1 billion in 2025 with an annual growth rate exceeding 17%. According to industry statistics of 2025, 47% of firms operating in the field have initiated BSF pilot programs, while 41% of those companies increased their farming capacity in that same year.

Investing in insects is no longer about hedging against an uncertain future. Insect protein has gone from being speculative to strategically sound investment in many parts of the world at once.

The investment follows the trend. Next Protein raised €18 million in its Series B round of financing to upscale BSF production for the purposes of aquaculture and livestock production. Nutrition Technologies received $28 million to develop insect protein farming capacity in Southeast Asia — namely in Thailand, Vietnam, and Indonesia right where aquaculture needs are the highest. Ultranutri has received strategic financing for scaling up BSF-based shrimp feed production.

Progress within regulations has further boosted confidence within the market. In September 2025, there was an influx of approval for insect-based feeds both in Europe and Asia Pacific which was considered by experts as a tipping point from a business perspective. In China’s 14th Five-Year Plan, more than RMB 50 billion has been invested in aquaculture infrastructure.

Market overview

Asia Pacific accounted for the largest share of the market with $5.1 billion or 41.3% of the worldwide sales, thanks mainly to the massive share of China in global farmed fish output as well as the quick expansion of the shrimp segment in India, Vietnam, and Bangladesh. APAC will prove to be the fastest growing regional segment with a CAGR of 7.6% until 2034.

As per the Dataintelo research, the larger trend has been identified in which conventional fishmeal, which used to contribute about 65% of the protein content in the feed for salmonids, now contributes to around 38%. Leading producers including Mowi ASA and SalMar ASA have committed to cutting inclusion rates further by 2030. Cargill, identified in the report as the leading company in the competitive landscape, has invested substantially in alternative protein capabilities to serve this transition.

High costs continue to hamper competitiveness in markets most sensitive to pricing. Consistency of the substrate the organic waste materials fed to insects necessitates infrastructure not available in all areas. Finally, growing the insect industry enough to supply sufficient quantities of insect protein for aqua feed remains a project requiring years rather than months to accomplish. Still, they are not insurmountable problems.

The protein revolution in aquaculture driven by insects is not something for the distant future. The mills in Norway, Vietnam, Chile, and India have already witnessed the revolution.

The aquaculture industry is witnessing an unprecedented transition when it comes to proteins. Insects offer a very efficient and circular solution, and the best part is that they are becoming more cost-effective every day. Their larvae might be small, but the industry they are transforming is far from being small.
