Queen Scallop in Ferrol: what could change for the shellfish sector

Key data

Fishing cooperatives and shellfish operators in the Ferrol estuary have reason to monitor the Zamfer project closely. The agreement between the CSIC and the Xunta de Galicia, published in the BOE on April 9, 2026, does not impose immediate restrictions, but activates a scientific process whose conclusions could lead to concrete regulatory changes regarding the exploitation of queen scallop (Mimachlamys varia) in this environment.

This is not a minor administrative procedure. The collaboration between a top-tier scientific organization like the CSIC and the Galician regional administration strengthens the technical basis for future regulatory decisions. When studies of this type conclude, their recommendations are typically translated into sector-specific regulations.

What does this regulation establish?

The agreement formalizes the Zamfer project (Evaluation of the status of queen scallop populations in the Ferrol estuary: an integrated approach to their conservation and sustainable management). The study will adopt an approach combining three types of analysis:

• Biological analysis: evaluation of the status of the Mimachlamys varia species in the Ferrol estuary.
• Ecological analysis: study of the environment and factors conditioning population viability.
• Management analysis: evaluation of current exploitation practices and their sustainability.

The stated objective is twofold: to design conservation strategies and establish criteria for sustainable exploitation of the resource. Both objectives have direct implications for regulating shellfish activity in the area.

The agreement does not specify duration, budget, or results delivery dates in the published information.

Economic and operational impact

The direct economic impact of this agreement is not immediate, but the regulatory risk it generates is real and must be managed proactively. Possible scenarios once the study concludes include:

• Quota restrictions: limitation of queen scallop extraction volumes permitted in the Ferrol estuary.
• Changes in extraction methods: possible prohibitions or conditions on currently used techniques and gear.
• New monitoring obligations: operators could be required to report catch data in greater detail to feed sustainable management systems.
• Closure periods or exclusion zones: depending on the actual status of populations, the study could recommend temporary or spatial protection measures.

The institutional collaboration between the CSIC and the Xunta strengthens the technical weight of the conclusions, increasing the likelihood that the project's recommendations will translate into effective regulation.

Who does it affect?

• Fishing cooperatives in the Ferrol estuary: they are the operators directly exposed to possible changes in quotas and extraction methods.
• Shellfish harvesters and companies in the shellfish sector in the Ferrol estuary: any operator extracting queen scallop (Mimachlamys varia) in this geographic area.
• Galician administration (Xunta de Galicia): as a signatory to the agreement, it will be responsible for translating the study's conclusions into regulatory decisions.
• Queen scallop traders and distributors: a reduction in quotas or extraction restrictions would affect available volume and therefore prices and supply chain.

Practical example

A fishing cooperative in the Ferrol estuary currently extracting queen scallop under current regulatory conditions should consider the following scenario:

The Zamfer project concludes that Mimachlamys varia populations in the estuary are below the sustainability threshold. The Xunta de Galicia, backed by CSIC scientific data, decides to reduce annual extraction quotas or establish a temporary closure in certain estuary zones.

For that cooperative, this translates to: lower permitted catch volume, possible need to redirect fishing effort toward other species or areas, and adaptation of fishing gear if current methods are identified as incompatible with species conservation.

The time to prepare is not when the restriction is published, but now: while the study is underway and there is still room to participate in consultation or objection processes that may open.

What should companies do now?

1. Identify if you operate in the Ferrol estuary with queen scallop: if your shellfish activity includes extraction of Mimachlamys varia in this area, this agreement directly affects you.
2. Document your current activity: record extraction volumes, methods used and operation zones. Having your own data will allow you to respond with solid arguments in future regulatory consultation processes.
3. Monitor the progress of the Zamfer project: track publications from the CSIC and the Xunta de Galicia related to this project to anticipate conclusions before they translate into regulation.
4. Contact your cooperative: fishing cooperatives are the natural channel for representation before the Galician administration. Ensure your voice is present in any participation processes that open.
5. Evaluate alternative business scenarios: if a quota restriction or change in extraction methods affected your activity, do you have the capacity to redirect effort toward other species or areas? Planning this now reduces future impact.
