More structure means an easier life for trout

Large woody debris (‘snags’) are important structures for fish but there has not been a lot of research into how wood affects fish behaviour.
Researchers in the USA looked at how the behaviour of brown trout changed in the presence of wood.
They found that the presence of large wood significantly reduced the overall activity of the fish.
The fish also caught more food relative to the time they were active so they had a net energy gain.
