Extract

1. The changes brought about in the colour of the gills of rainbow trout and sea trout smolts by various poisons are described.

2. Cyanide causes a marked brightening, whilst phenolic substances, dissolved oxygen deficiency and naphthalene bring about a darkening of the gill colour. Fresh, untreated sewage has no effect.

3. The gill colour of smolts dying in the Tees Estuary was brighter than normal, indicating cyanide poisoning. This conclusion was confirmed by chemical methods.
