[4] The town is notable as it was the location of the first introductions of brown trout outside their native range when in 1864, 300 of 1500 brown trout eggs from the River Itchen survived a four-month voyage from Falmouth, Cornwall to Melbourne on the sailing ship Norfolk.

[5] Atlantic salmon, although successfully reared in the Plenty river hatchery and introduced at the same time under the sponsorship of the Acclimatization Society of Victoria, failed to establish themselves in Tasmania or Australia.

[6] In 2020, hazardous substances from local composting business Jenkins Hire were allegedly dumped into the nearby Plenty River, resulting in the death of over 100,000 fish.

The company produces compost by mixing waste discarded from the pulp and paper mill Norske Skog Boyer, the salmon farming industry, and treated sewage sludge from TasWater.

Improper accumulation of waste without adequate drying can produce noxious leachate, contaminating surrounding soils.
