Escaped farm salmon

An escaped farm salmon - note the shape of the tail and fins (Ben Rushbrooke)

Escaped farm salmon have been recorded in WRFT rivers for almost 20 years. During the early 1990s, progeny of escaped female farm salmon were recorded in many of the rivers in the area demonstrating that female farmed salmon had successfully spawned.

Escapes of salmon from farms around Wester Ross are reported most years. In 2007, 24,000 salmon were reported to have escaped from a farm in Loch Ewe; within the same area 25,000 salmon escaped from nearby farms in 2003.

WRFT has monitored numbers of escaped farm salmon smolts leaving Loch Damh in 2000 and carried out studies of escaped farm smolts in Loch Tollie in 1999 and records escaped farm salmon in fish trap catches and through fish scale reading.

  • Still too many sea lice?
    Presentation with summary of sea lice problems and results from sea trout sea lice monitoring by WRFT in 2023. Sea lice levels were too high on many sea trout at some sites. The risk of damaging levels of sea lice infestation to emigrating wild salmon post smolts through the Inner Sound may have also been too high. How many grilse will return to rivers in southwest Ross-shire compared to rivers in northwest Ross-shire in 2024? .  Posted: 01/05/2024 (9.90MB)
  • Malnourished salmon rivers? How important were salmon eggs as food for parr?
    Presentation which considers the importance of salmon eggs as a food for pre-smolt salmon parr during the early winter. Is there a need to focus on ways of replacing this direct source of marine derived nutrition from adult salmon to juvenile salmon to help to mitigate for downward spiral of decline in numbers of adult salmon returning to oligotrophic rivers?.  Posted: 01/05/2024 (7.42MB)

  • Juvenile salmon production and nutrition in Wester Ross 2023
    This report summarises the results of the juvenile salmon survey in Wester Ross in summer and early autumn, 2023. The report focusses on contrasting the size and biomass of juvenile salmon at different sites. There was much variation in growth; some sites had high densities of larger parr; at other sites parr were small and thin. Important missing food items for parr at some sites may include caddis fly larvae, terrestrial insects, and surplus washed-out salmon eggs which in some rivers may have been of crucial importance for pre-smolt salmon parr. Is it time to provide supplementary food for juvenile salmon in some rivers? .  Posted: 05/02/2024 (1.65MB)
  • Finding Salmon and Sea trout around the Wester Ross MPA
    This presentation by Peter Cunningham introduces the main wild salmon rivers that flow into the Wester Ross MPA and describes some of the issues, including infestation by sea lice from poorly regulated open cage salmon farms, which threaten wild salmon populations and sea trout within the Wester Ross area. Can the wild salmon populations around the Wester Ross MPA be given additional protection?.  Posted: 27/10/2022 (11.01MB)

    Geoffrey Billier sampled macro-invertebrates and investigate the feeding behaviour of juvenile salmon in the Little Gruinard river, during a three-month internship for WRFT, as part of his studies at Ecole Nationale Sup?rieure Agronomique de Toulouse 'ENSAT'. This report provides much new information about the biodiversity of macro-invertebrates in the river, drift patterns (day & night) and the diet of salmon fry, parr and smolts.  Posted: 30/09/2014 (3.22MB)
