Non-vegetarian brown trout

Well I suppose they all are – non-vegetarian, that is, but this big brown trout from the river this morning was a confirmed meat eater. A quick autopsy in the office revealed its diet last night: a mouse and a small trout.

The stomach contents, a well digested mouse and what looks like a small trout although it was hard to say due to the digestion.

The stomach contents: a well digested mouse and what looks like a small trout although it was hard to say due to the digestion. The flesh was pale but the lower jaw looked trout like. I haven’t seen anyone using a mouse imitation fly on the Spey yet but they are commonly used whilst specimen hunting in the US and in New Zealand. The use of such a fly on a dark evening could be quite exciting.

Scales were taken but not yet read (they have to dry first) but similar trout from the Spey tend to be 8 to 10 year old.

It should be said that trout of this size are not uncommon in the Spey so the harvesting of the occasional fish has little impact at a population level.
