Here we will in a simple way describe a few of the problems that can arise while fishing, and different things you can possibly do in order to improve the situation as best you can. For simplicity we will keep to single bottom trawls and pelagic trawls, but where it is relevant, it also applies to twin rigs, pair trawls, semipelagic trawls, shrimp trawls and Danish sein.

Everything we refer to here is what fishermen have done in different situations and which we believe has been of great help to them.
