Fishing days for bottom trawlers Mediterranean 2026: 1,815 days available and how they are distributed

Key data

Bottom trawlers in the western Mediterranean already know their operational ceiling for 2026: 1,815 fishing days in total, distributed among four length segments. The Resolution from the General Secretariat of Fisheries, published on October 20, 2026, activates the annual optimization mechanism that allows vessels that exhaust their individual quota to access unused days from other vessels in the same fleet, avoiding forced stoppages that directly impact the bottom line.

What does this regulation establish?

The resolution publishes the quantities of fishing days available for the annual optimization mechanism of the western Mediterranean bottom trawl fleet in 2026. This mechanism works like a pool of days: when a vessel exhausts its individual allocation, it can access days not consumed by other vessels in the same fleet, preventing it from having to moor early.

The 1,815 days are distributed across four length segments. The calculation was made using the most conservative scenario, considering three variables: fishing closures in force, actual vessel activity, and the fleet's census situation.

The key operational aspects established by the regulation are:

• Day redistribution: unused days by one vessel can be used by others in the same group, avoiding forced stoppages.
• Conversions between length segments: conversions of days between different segments are permitted by applying the ratios established in previous regulations.
• Conversions between fisheries: it is also possible to convert days between different fisheries, always with applicable regulatory ratios.
• Joint management: vessels integrated into a joint management entity can use days allocated to other vessels in their same entity, even if they belong to a different length segment.
• Biweekly update: available quantities are updated every two weeks through the Gestcuotas application, which is the official monitoring tool.

Economic and operational impact

For a shipowner or fishing company, each fishing day lost due to individual quota exhaustion represents a direct cost in crew, vessel depreciation, and loss of income. The optimization mechanism is, in practice, an operational safety net: it allows continued fishing when the individual quota has been exhausted, as long as days are available in the collective pool.

The points of greatest economic and operational impact are:

• Campaign planning: knowing the total of 1,815 days from the start allows shipowners to plan their departure schedules with greater precision and optimize fixed costs.
• Conversion flexibility: the possibility of converting days between length segments and between fisheries provides room to adapt activity to market conditions or fishing ground conditions at any given time.
• Advantage for joint management entities: companies or fishing associations that manage several vessels jointly have greater internal redistribution capacity, reducing the risk of unplanned stoppages.
• Risk of early exhaustion: if the collective pool is consumed before year-end, vessels that have not exhausted their individual quota will also not be able to transfer days. Biweekly monitoring in Gestcuotas is critical to anticipate this scenario.

Who does it affect?

• Shipowners of bottom trawl vessels operating in the western Mediterranean.
• Fishing companies with fleets in the four regulated length segments.
• Joint management entities that group several vessels under the same organization.
• Fishing associations and producer organizations in the western Mediterranean with trawl fleets.
• Managers and advisors of fishing companies that use the Gestcuotas application for quota monitoring.

Practical example

Imagine a fishing company with three bottom trawl vessels in the western Mediterranean, integrated into a joint management entity and belonging to two different length segments.

By mid-November, one of the vessels in the smaller segment exhausts its individual fishing days. Thanks to the optimization mechanism, the company can check in Gestcuotas (updated every two weeks) whether days are available in the collective pool. If another vessel in the entity—even if it belongs to a different length segment—has not consumed all its days, the company can transfer them by applying the conversion ratio established in previous regulations, allowing the first vessel to continue fishing without mooring.

Without this mechanism, that vessel would have had to stop, assuming fixed crew and depreciation costs without generating income. Biweekly monitoring in Gestcuotas is what allows detection in time if the collective pool is close to exhaustion and adjustment of the activity of all three vessels in a coordinated manner.

What should companies do now?

1. Access Gestcuotas and verify the allocation of days corresponding to each vessel and length segment for fiscal year 2026, confirming that census data is correct.
2. Review conversion ratios between length segments and between fisheries established in previous regulations, to know in advance what conversions are possible and under what conditions.
3. Plan the departure schedule taking into account the total of 1,815 days available for the fleet, fishing closures in force, and expected actual activity, to avoid premature exhaustion of the collective pool.
4. Coordinate joint management if the company operates several vessels under the same entity: identify which vessels have greater day margins and how to optimally redistribute them among segments.
5. Establish a biweekly review schedule in Gestcuotas, coinciding with each official update, to detect in advance if the collective pool is approaching exhaustion and adjust activity in time.
6. Check the census situation of each vessel, since the calculation of available days is based on the most conservative scenario also considering the census situation; any change in the fleet must be reported so that data is correct.
