Variations On Salmon
The main difference is that the person playing the weak-side position has a lot of flexibility and can either play up or back depending on the situation and how the other team has been beating you. It also puts a permanent player in the middle of the field, the middle-middle. This person now becomes responsible for positioning and communicating with the short middle which is also very important.

The final twist is that the short-middle will mark the disc and take away the dump in the trap set. The fish then cuts off the swing pass. This has the added advantage of giving the fish a bit of a break and making it easier for the fish to mark the disc once the other team gets out of the trap situation.

Endzone Set
When the disc gets to close to the endzone, the regular salmon set-up is not necessarily the best, because it does not collapse very nicely in the short space. However, without to much trouble, the zone can be reconfigured.

It's not really important where everyone lines up in the line of four. The important thing is to have the right (or weak-side player) take one back corner and the deep take the other. This is done because next to the deep, the weak-side player should be able to cover the most ground and read plays the best. The line of four listens to the people behind them for directions. The player on the disc will mark the disc back towards the middle of the field. When the disc gets moved, the marker and the four defenders in a line will rotate. When leaving the wall to mark the disc, it is important to approach the disc cautiously, trying not to allow the thrower to throw to the space you just vacated, because the wall will need a few seconds to adjust.
