Order on the RSF auction

When the catalog on the RSF auction is made it is ordered by the following.

1. Specie
2. Condition (Ungutted-Gutted)
3. Size (smalles first)
4. Gear
5. Age (oldest first)

Then there are a few things that are ordered randomly and shuffled every day.
They are:

6. Part of country. The country is divided into 5 parts.
7. Supplier – size. This combination is shuffled every day. This means that a supplier can be number 1 in the auction in one combination (supplier 1 – size 1) but number 3 in another (supplier 1 – size 2).
8. Harbour.
