No ice left in the package, the parcel took two days, the box was intact but the fish smelled: online fish-order complaints revolve around these three sentences. The buyer blames the courier; yet all three point at decisions made at the dispatch desk.

Two truths that make fish hard

The first is water: ice melts and leaves a liquid touching the flesh; managing meltwater is an engineering job in itself, and the meltwater article shows how it is set up. The second is speed: in some fish a temperature rise feeds the histamine risk, which means delay costs more in fish than in other foods.

Order at the dispatch desk. Dispatch days are fixed against courier times, frozen and fresh products are planned separately, and the ice ratio is calculated from journey time and season; the ratio itself is worked out in the article on shelf life and ice. Sending a test parcel to your own address before the first sale is the cheapest exam this whole calculation will ever sit.

When a complaint does arrive, the record takes over: writing down the delivery time, the parcel photos and the decision taken both shortens the refund argument and keeps the same mistake from happening a third time.

Frequently asked question

Is a polystyrene box not enough?

For a one-off shipment it serves. In regular sales three shortcomings surface: it is bought anew for every parcel, it cannot hold meltwater, and it is not a container that can enter a hygiene record. Choosing a fish transport container, and the difference between a closed base and a drained one, are compared in separate articles.
