Section 30

Hi here's a copy of the Section 30 from the EA site.

Before you introduce any fish into any water you must be in possession of a written consent from the Environment Agency under section 30 of the Salmon and Freshwater Fisheries Act 1975. This requirement applies to all waters except fish farms in England and Wales, including rivers, canals, reservoirs, lakes and ponds, whether public or private. If the fish intended for introduction are not native to the British isles you will also need a licence under the Wildlife and Countryside Act 1981 and/or a licence to keep under the Import of Live Fish Act 1980, in addition to consent under Section 30.

Does this cover all fish? IE do petshops/garden centers and buyers need one?
Do Koi dealers require one and buyers and due to the fact they are not native do they require the others?

I'm lost a little as to what is the legal standing on this law. I know I can't move fish from my pond to my lake or from the lake to my pond but how do shops or Koi dealers avoid this?

Here's the link to the information on the above if it helps.
