Summary of Invasiveness

Top of page

Introduction of Salmo trutta has caused both negative and positive impacts on biodiversity. They compete with native trout and other fish species, but they are not known to have been the cause of any species' extinction (Animal Diversity Web, 2004).

Description

Top of page

Salmo trutta has a fusiform body with a small pointed head, large mouth, extending mostly after the eye (Rochard and Elie, 1994). S. trutta or brown trout get their name from the brown or golden brown hue on their bodies. Body is grey-blue coloured with numerous spots, also below the lateral line (Rochard and Elie, 1994). Blackish coloured on upper part of body, usually orange on sides, surrounded by pale halos. Adipose fin is with red margin (FishBase, 2004). Sea-run S. trutta have a more silvery coloration and the spotting is less visible (Nova Scotia, 2004). It has 3-4 dorsal spines, 10-15 dorsal soft rays, 3-4 anal spines and 9-14 anal soft rays (FishBase, 2004). Caudal fin has 18-19 rays (Spillman, 1961). Caudal peduncle is thick and rounded (Rochard and Elie, 1994). It has a few scales (Rochard and Elie, 1994).

S. trutta closely resemble Atlantic salmon and rainbow trout, but salmon have no red coloration on the adipose fin and rainbow trout have lines of black spots on the tail. Young S. trutta (parr) have 9-14 dark narrow parr marks along the sides and some red spotting along the lateral line (Nova Scotia, 2004). S. trutta can grow to be quite large, especially sea-run fish. It can grow to a standard length of 140 cm (Muus and Dahlström, 1967). Maximum published weight is 50.0 kg (Muus and Dahlström, 1967) and maximum reported age is 38 years (FishBase, 2004).

Distribution

Top of page

The native range of Salmo trutta includes Europe, northern Africa and western Asia. The species is found in Iceland and on the northwest coast of Europe, along the Mediterranean and south to India. S. trutta has been introduced to appropriate streams all over the world (Animal Diversity Web, 2004) and today is found in rivers, lakes and coastal areas (Nova Scotia, 2004).

Impact: Biodiversity

Top of page

Salmo trutta has been implicated in reducing native fish populations (especially other salmonids) through predation, displacement, and food competition (Taylor et al., 1984). There are some negative effects from S. trutta since the species was introduced in America (Animal Diversity Web, 2004). They compete with native trout and other fish species, but they are not known to have been the cause of any species' extinction. In California, USA, competition and predation from S. trutta may have contributed to the decline of the dolly varden, Salmo malma, in the McCloud River (Moyle, 1976), and of the golden trout, Oncorhynchus aguabonita, in the Kern River (Courtenay and Williams, 1992). S. trutta may have also depleted the Modoc sucker, Catostomus microps, an endangered species, in Rush Creek, Modoc County (Moyle and Marciochi, 1975). S. trutta have commonly replaced cutthroat trout, O. clarki, in large rivers (Behnke, 1992). Another negative effect is their contribution to the lamprey population in many rivers. The increased lamprey populations since S. trutta were introduced have been considered as a negative impact on biodiversity (Animal Diversity Web, 2004). S. trutta introductions may have caused the decline of the Tasmanian mountain shrimp, Anaspides tasmaniae, and have eliminated or reduced several Plecoptera and Trichoptera species in streams in Victoria, Australia (Arthington, 1989).

It interacts ecologically with other species and healthy populations of brown trout are necessary for the reproduction of the freshwater pearl mussel, Margaritifera margaritifera (Laikre et al., 1999).
