Fiordland Mouse Trout

A strange phenomena occurs every 5 or 6 years in the beech forests of New Zealand’s South Island when there is a widespread beech tree seeding or masting. The mice feed heavily on the fallen seeds, which leads to a population explosion. Within a few months the mice are literally everywhere. The trout are very quick to seize upon this new source of protein, feeding heavily on mice that enter the water during the night. The result is trout that grow to epic proportions!

This episode we join Anto Hall and Nick Geddes as they search the remote lakes of Fiordland for these mysterious ‘mouse feeding trout’ and Anto manages to catch the largest brown trout of his life!
