Consumer Information
Brown or Sea Trout (also has a number of regional names around the UK including sewin, finnock, peal, mort and white trout ) may be caught in the wild, although also farmed. It belongs to the salmon family and is adapted to life in both fresh and sea water. Wild sea trout populations are threatened in some areas. Most trout on sale however, are rainbow trout which is the most popular farmed species of trout, with most production taking place in freshwater. Also a member of the salmonid family, rainbow trout are native to western North America and range from Alaska to Mexico. Only eat wild line-caught sea trout from well-managed fisheries, such as a rod & line fishery. Avoid eating fresh sea trout caught during the breeding or spawning season from November to March inclusive. Buying organic farmed trout is the best choice as fish stocking densities are generally lower in comparison to non-organic farms, feed is sourced sustainably and fish welfare is higher. Trout can be steamed or baked, whole or filleted, and is really tasty when cooked in the microwave. Also popular smoked. Not strongly flavoured. It's low in fat only a third of the fat of salmon and just 135kcals per 100g. Salmonids are oily fish rich in omega 3.
Summary
Rainbow trout is a non-indigenous species and was introduced to Europe from the USA. There are very few self-sustaining or breeding populations in Europe. Supplies are maintained chiefly through farmed fish. Trout is widely farmed in UK, mainly in freshwater, location of farms is determined by the proximity of a clean river to provide water. Trout farming takes place mainly in ponds, tanks or raceways with water being supplied from an adjacent river. Trout are carnivorous fish whose feed relies on wild fisheries. Buying organic farmed trout is the best choice to make as fish stocking densities are generally lower in comparison to non-organic farms, feed is sourced sustainably and welfare of a high standard.
