Buying at the fish auction (criée) means bidding yourself on whole lots, as a buyer declared to the auction hall; buying from a fish merchant (mareyeur) means entrusting them with that purchase, the sorting and the shipping; buying from a wholesaler means paying for one more link for local delivery, with little or no minimum, on a wide range. The right channel depends first on your weekly volume, then on your trade and your distance from the port.

The "Find a fish merchant" hub describes who does what. This guide goes further: what each channel requires of you, what it costs you, and from what volume it becomes worthwhile.

Can you buy at the fish auction yourself?

Yes, under conditions designed for wholesale buying: the French rural code speaks of a first placing on the market "en vue de leur vente en gros" (with a view to selling them wholesale) (Art. D. 932-8).

  • Declare yourself to the auction hall operator. The buyer provides proof of registration in the trade and companies register or the national business register (food trades or seafood processing), their VAT number and the details of their guarantee. The hall keeps the list of declared buyers (French Rural and Maritime Fishing Code, Art. D. 932-8 and D. 932-9).
  • Lodge a guarantee. It secures payment for the lots bought, which the hall passes on to the vessel owners. Its amount corresponds to the financial cover of your purchases (rural code, Art. D. 932-9). A national fund managed by FranceAgriMer, the FNCA, can supplement this guarantee for declared buyers who belong to an approved mutual guarantee company.
  • Comply with the operating rules of each hall, set by the prefect: conduct of sales, payment terms, penalties (rural code, Art. D. 932-11 and D. 932-12). The fees charged by the hall are added to the hammer price: ask for the port's fee schedule.
  • Be present or connected. Depending on the auction, you bid in the room, remotely, or both: at Boulogne-sur-Mer, the sale is open to fishmongers and restaurant owners, in the room or remotely, after registering with the auction's guarantee body (see the port page).
  • Take the whole lot. A lot generally groups one or more boxes of the same species, the same size grade and the same freshness category. You do not pick 4 kg from the box.

Once the lot is knocked down to you, it is yours: preparation, icing, transport and unsold stock are at your expense.

Fish merchant or wholesaler: what changes for you?

CriterionDirect at the fish auctionFish merchantLocal wholesaler (MIN wholesale market, Rungis, delivery firm)
AccessDeclaration, guaranteeAccount opening, sometimes a first payment in cashBuyer's card at the wholesale market, or a simple customer account
Purchase unitThe whole lot (one or more boxes)The parcel, at the weight set by the fish merchantThe kilo, sometimes the piece
Free delivery and minimumNot applicable, you collectMinimum per parcel; free delivery above a weight or an amountLittle or no minimum on a delivery round
Lead timeThe day of the sale, if you are on siteGenerally delivered the next day, depending on the fish merchant and the carrierThe same day or the next day
RangeThat of the port, that dayThat of their port and neighbouring auctionsSeveral ports and imports
PreparationAt your expenseSorting, gutting, filleting on requestDepending on the wholesaler
Freshness riskYours from the moment of the hammerShared: the fish merchant on preparation, you or them on transport depending on whether the sale is ex-works or deliveredThe wholesaler's until delivery

Units, minimums and lead times vary from one supplier to another: these are orders of magnitude.

Who bears the freshness risk during transport?

It is the question people forget to ask. Under French law, unless otherwise agreed, goods that have left the seller's premises travel at the risk of whoever owns them (Commercial Code, Art. L. 132-7). In practice:

  • Ex-works sale (vente départ): the price is understood at the fish merchant's dock. Transport is invoiced on top, and a parcel that warms up on the way is first your problem, with recourse against the carrier.
  • Delivered sale (vente rendue): transport is included and, if agreed, the fish merchant takes responsibility for arrival in good condition. A free delivery threshold (franco de port) says who pays for transport, not necessarily who bears its risk: have it specified in writing.

Which channel for which profile? The decision table

ProfileSeafood volume per weekMain channelAs a complementWhy
Restaurant, short menuLess than 20 kgLocal wholesaler or fishmonger who deliversA fish merchant for a signature species, in a grouped parcelThe minimum parcel and per-parcel transport weigh too much per kilo
Restaurant, seafood menu20 to 80 kgOne or two fish merchants directLocal wholesaler for top-upsFree delivery becomes reachable by grouping orders over two or three days
Fishmonger, fine-dining restaurant or small group80 to 300 kgTwo to four fish merchants from different portsWholesaler for imports and shortfallsSeveral ports for regularity; enough volume to negotiate delivered prices
Wholesale fishmonger, regional wholesaler300 kg to 1 tFish merchants, several coastsBuying at auction if a port is nearbyThe volume justifies declaring at auction for key species
Exporter, national wholesalerMore than 1 tFish auctions direct (often remotely) and fish merchantsFish merchants for preparation and export packingThe cost of the guarantee and staff is spread over tonnes

Editorial benchmarks, neither a standard nor a statistic: the right thresholds depend on the distance from the port, the number of species and the delivery day.

Two rules emerge. First, the more species you buy, the more you need several suppliers, because no port has everything. Second, buying direct at auction is only worth it if you know how to handle the whole lot, from gutting to reselling the fish you do not need.

What does the channel change on the delivered price? An illustrative example

Item, in € per kgDirect at the fish auction (buyer close to the port)Fish merchant, 10 kg parcel, ex-works saleFish merchant, 40 kg, free deliveryLocal wholesaler, 3 kg on a delivery round
Hammer price at auction10.0010.0010.0010.00
Buyer's auction fees (assumption 2%)0.200.200.200.20
Box, ice, labelling0.300.300.300.30
Fish merchant's gross margin (workshop, staff, unsold stock, profit)2.002.002.00
Fish merchant ex-works price12.5012.5012.50
Transport0.50 (collected by you)1.80 (€18 per parcel)Included by the fish merchant, about 0.700.60 (shared pallet)
Wholesaler's gross margin (assumption 20% of the selling price)3.28
Delivered price to you11.0014.3013.2016.38

Illustrative example, hypothetical amounts. Free delivery does not remove transport: the fish merchant builds it into their price or margin.

Three readings:

  1. The price gap comes mainly from per-parcel transport and successive margins, not from the auction price. Between a single parcel and an order at the free delivery threshold, the same fish loses €1.10 per kilo here.
  2. The wholesaler costs more per kilo, but not necessarily more per dish. They sell 3 kg where the fish merchant imposes 10 kg: if 7 kg end up badly, the low price no longer exists. The food cost guide does this calculation.
  3. Buying direct at auction looks unbeatable as long as you do not count the time spent, the guarantee tied up, preparation and the unsold part of the lot.

To set side by side suppliers who sell some ex-works and others delivered, always bring each line back to the price delivered to you. The price list guide gives the method.

How to combine channels?

Most regular buyers do not choose one channel, they assemble two or three:

  • one or two reference fish merchants for key species, at the free delivery threshold, with stable size grades;
  • a fish merchant on another coast to cover days of bad weather on the first;
  • a local wholesaler for top-ups, imports and small quantities.

Each sends their price list, at their own time and in their own format. That is where comparing takes time: everything has to be brought back to the same species, the same size grade and the same delivered price before ordering.

Frequently asked questions

Can a restaurant owner buy directly at the fish auction?

Yes, if they declare themselves as a buyer to the auction hall operator, with their registration in a professional register, their VAT number and a guarantee covering their purchases (rural code, Art. D. 932-9). They must then take whole lots: for a few dozen kilos a week, a fish merchant from the port remains the simplest route.

What is a free delivery threshold (franco de port) for seafood?

It is the threshold, in weight or amount, above which the supplier pays for transport. Below it, transport is invoiced on top, for example per parcel. The free delivery threshold says who pays for transport; who bears its risk is agreed separately.

Is the wholesaler always more expensive than the fish merchant?

Per kilo, generally yes, since they add their margin. On the delivered price and for small quantities, the gap narrows, because they deliver with no minimum and share transport.

Can you buy at a fish auction remotely?

Yes, at auctions that offer it, such as Boulogne-sur-Mer. The access conditions remain the same as for a buyer on site: declaration and guarantee.

Who pays if the fish arrives warm?

Unless otherwise agreed, goods travel at the risk of whoever owns them (Commercial Code, Art. L. 132-7): in an ex-works sale, it is generally you, with recourse against the carrier; in a delivered sale, if agreed, the supplier. Write your reservations on receipt and notify the supplier without delay.

How many suppliers do you need to be well supplied?

At least two different ports for your key species, plus a local top-up. Beyond that, each added supplier is one more price list to read every morning.
