Mauritania Octopus Fishing Seasons: Winter, Summer, and Year-Round Supply

The two octopus fishing seasons in Mauritania

Octopus fishing off Nouadhibou runs in two distinct windows. The winter season opens December 1 and runs through April 30 — five months of active fishing. The summer season opens July 1 and runs through October 30 — four months. Together the two windows provide approximately nine months of fresh production per year, with May–June and November as transition periods between seasons.

Both seasons fish the same Atlantic grounds off Nouadhibou — the zone where the cold Canary Current upwelling meets the shallow West African continental shelf. Maurimar fishes both windows using its own artisanal fleet, with hand-line and traditional pot methods — no industrial trawling. Each vessel's ID and catch zone are logged at the point of capture. For the full production sequence from fishing to reefer container, see Maurimar's process page.

What characterizes the winter season?

The winter season runs from December 1 to April 30. The cold Canary Current upwelling intensifies during these months, driving higher biomass concentration in the fishing zones off Nouadhibou. Water temperature at depth is at its lowest of the year — conditions that produce firm, well-conditioned octopus with the tight muscle structure that sashimi and premium retail buyers require.

The winter window is the primary production period for Fresh Frozen Japan Quality octopus. Buyers supplying the Japanese sashimi market, premium European retail chains, and high-end food service typically orient their annual sourcing plan around the winter window. Each catch lands at Nouadhibou port, is hand-graded on the dock under ONISPA-certified procedures, and enters the IQF blast tunnel the same day — the sequence that defines the Japan Quality grade.

What characterizes the summer season?

The summer season runs from July 1 to October 30. Sea surface temperatures are higher than in winter, but the fishing grounds off Nouadhibou remain productive — the Atlantic shelf sustains strong octopus populations across both seasons. The summer window delivers consistent catch volumes with good product condition throughout the four-month period.

Food-service operators, processing buyers, and re-packers who work in batch production frequently source from the summer window. The Iced grade — export-quality product held on ice for one to three days before freezing — is well suited to these channels and is available year-round, including from summer-season production. Both IQF and block-frozen formats are available on every order, in all seven calibers T1 through T7.

What happens between seasons?

Between the winter and summer windows — May, June, and November — Maurimar ships from deep-frozen reserve. Product from peak-production lots is held at −18 °C or below in Maurimar's cold-storage facility at Nouadhibou. At this storage temperature, the product carries a 24-month shelf life from the freezing date, which means peak-season stock remains fully within specification well into the transition periods.

Between-season product ships under the same ONISPA sanitary certificate, the same specifications, and the same documentation set as in-season product. From the buyer's perspective, the supply chain is continuous — there is no gap month in which Maurimar cannot ship. For buyers with year-round procurement programs, the transition periods are operationally seamless. For traceability and certification details, see Maurimar's quality and traceability page.

Why place your order before the season opens?

The practical answer is access: price, product, and production slot. Buyers who commit at or just before season open secure all three; buyers who wait until the season is underway find all three tighter.

Price. Early-season commitments are confirmed against the production schedule before demand from multiple buyers accumulates. Maurimar's pricing is specification-driven, not auction-based — but buyers who engage early, with clear specifications and confirmed quantities, are in the strongest position to agree terms before the season's production is committed to others. Waiting until peak season, when multiple buyers are active, reduces negotiating leverage.

Product quality and availability. The first weeks of each season produce fresh-catch lots with the highest product condition of the year — this is when the catch is coming off the best-conditioned grounds and moving through the production process within hours of landing. Buyers who commit early get first access to these lots. As the season progresses and production fills existing orders, availability by specific format, format, or treatment narrows. The best product does not sit in cold storage waiting for late buyers.

Production slot. Maurimar's production schedule is built from confirmed orders. An early commitment reserves a production slot, locking the buyer's specification — grade, format, treatment, quantity — into the schedule before it is allocated elsewhere. Late orders in a busy season may face a longer queue.

Practically, buyers planning Q1–Q2 imports (January through June delivery) should engage Maurimar in October or November, before the winter season opens on December 1. Buyers planning Q3–Q4 imports (July through December delivery) should engage in May or June, before the summer season opens on July 1. Submitting a quote request during these windows — with grade, format, quantity, and destination port specified — is enough to initiate the conversation and reserve availability. Use Maurimar's quote request form to get started.

How does seasonality affect lead time and pricing?

Lead time stays within the typical two-to-four week window from confirmed order, regardless of the season. FOB Nouadhibou, the buyer takes responsibility at the ship's rail — the destination sailing schedule, not the production window, is the main variable in total transit time. Maurimar's account manager coordinates production and container loading to match the buyer's requested departure window.

Pricing at Maurimar is driven by specification — grade, caliber, treatment, format, and quantity — not by the calendar. What does shift seasonally is the tightness of availability for specific combinations. A buyer who specifies a high-demand format in peak season and has not pre-committed faces a narrower set of available lots. A buyer who has committed before season open is already in the schedule at agreed terms. The seasonal calendar is therefore most useful as a planning tool, not as a pricing clock — the signal to act is the approach of a season-open date, not a price movement.

Frequently asked questions

The best time to source from Mauritania is the weeks before a season opens — when Maurimar's production schedule is still open, availability is widest, and early buyers set the terms for the season ahead.
