Charting a Course for Greener Small-Scale Fisheries: New SEAGLOW Report Explores the Market Opportunities Ahead

Across Europe’s coasts, small-scale fishers have long adapted to changing seas. They have navigated shifting fish stocks, evolving regulations, rising fuel costs, and increasingly unpredictable weather. Today, another transformation is on the horizon: the transition towards low-emission fisheries.

But unlike replacing a net or upgrading a piece of equipment, this transition is not simply a matter of adopting a new technology. It raises deeper questions about infrastructure, investment, markets, and the future of coastal communities themselves.

A new report published by the SEAGLOW project, Deliverable 5.1 – Analysis of Exploitation Opportunities, offers a detailed look at these questions. The study explores the market landscape surrounding low-emission solutions for small-scale fisheries in the Baltic and North Sea basins, revealing both the promise of greener technologies and the obstacles that still stand in the way.

A Sector Ready for Change, Yet Facing Uncertainty

The report paints a nuanced picture. The transition towards cleaner fishing operations is both necessary and possible, but it is unlikely to happen quickly.

Unlike sectors where large-scale investments and standardised technologies can drive rapid change, small-scale fisheries operate under very different conditions. Many vessels are family-owned, margins are often tight, and investment decisions carry significant risk. For many fishers, choosing a new propulsion system or fuel source is not merely a technical decision, but rather one that may affect the viability of their livelihood for years to come.

The study identifies several barriers that continue to slow the adoption of low-emission solutions. Alternative fuels remain difficult to access in many regions. Retrofitting or replacing engines requires substantial upfront investment. Uncertainty persists over which technologies will ultimately prevail. And small-scale fishers, purchasing fuel in relatively modest quantities, often lack the bargaining power enjoyed by larger maritime industries.

In this context, caution is understandable.

Beyond Vessels: An Opportunity for the Entire Maritime Ecosystem

Yet the report is far from pessimistic. If anything, it highlights the considerable opportunities emerging around the green transition.

One of its central messages is that decarbonisation will not be achieved by fishers alone. Instead, it will depend on the development of an entire ecosystem capable of supporting change.

Ports, for example, are positioned to become much more than places where vessels land their catch. They could evolve into green maritime hubs, providing charging infrastructure, fuel distribution services, storage facilities, and technical support for new energy systems.

Likewise, suppliers, shipyards, and technology providers stand at the forefront of a growing market. Demand for engine conversions, hybrid propulsion systems, energy-efficiency solutions, and retrofit services is expected to increase steadily in the years ahead. Given the long lifespan of fishing vessels and the relatively low rate of new vessel construction, retrofit solutions are likely to become one of the most important segments of the emerging market.

In many ways, the transition represents not only an environmental challenge but also an opportunity for innovation, entrepreneurship, and regional economic development.

Strength in Cooperation

For fishers themselves, some of the most promising opportunities may lie in collaboration.

The report suggests that stronger cooperation across the value chain could help reduce costs, strengthen negotiating power, and create clearer market signals for suppliers and investors. By working together, fishers may be better positioned to access emerging technologies and influence the development of solutions tailored to their needs.

There is also an opportunity to build a stronger identity around climate-friendly fishing. As consumers become increasingly aware of the environmental impact of the food they purchase, low-emission seafood could emerge as a valuable differentiator in the marketplace.

The Likely Path Forward

While much attention is often given to breakthrough technologies such as hydrogen or methanol, the report suggests that the immediate future will be shaped by more practical and incremental solutions.

In the short term, biodiesel appears to be the most realistic option for many operators. It offers the possibility of reducing emissions without requiring extensive modifications to existing vessels.

Further ahead, hybrid systems combining conventional fuels, biodiesel, and electric propulsion are seen as a particularly promising pathway. These solutions offer flexibility while allowing operators to gradually reduce their dependence on fossil fuels.

More advanced technologies remain part of the long-term conversation, but for now they are often constrained by high costs, infrastructure requirements, and technological uncertainty.

The transition, therefore, is unlikely to be defined by a single breakthrough. Rather, it will be characterised by a series of gradual steps, each building upon the last.

More Than a Technological Transition

Perhaps the report’s most important conclusion is that technology alone will not be enough.

Even the most promising solutions will struggle to gain traction without supportive policies, targeted investment, and appropriate infrastructure. Public funding, regulatory clarity, and long-term political commitment will be essential if low-emission fisheries are to move from pilot projects to widespread reality.

At the same time, the market itself may become a powerful driver of change. As retailers, processors, and consumers increasingly seek products with a lower environmental footprint, demand for climate-friendly seafood could create new incentives for adoption.

The transition, in other words, will be shaped as much by people and institutions as by engines and fuels.

A Shared Journey Towards Sustainable Fisheries

The story emerging from Deliverable 5.1 is not one of technological inevitability, but rather one of coordination, adaptation, and collective effort.

The future of low-emission fisheries will depend on fishers willing to innovate, ports prepared to invest, suppliers ready to develop new solutions, policymakers capable of creating enabling conditions, and consumers willing to support sustainable products.

The green transition of small-scale fisheries will take time. It will require patience, investment, and collaboration. Yet the opportunities are real, and the foundations are already being laid.

As SEAGLOW continues its work across Europe’s coastal regions, this new report provides a compass, helping stakeholders understand not only where the challenges lie, but also where the greatest opportunities for transformation can be found.
