Conservation & Management
Fish populations and fisheries across the world have been subject to a wide range of pressures caused directly or indirectly by human activities. The majority of the world's commercial fish stocks are 'over-fished'. This means that they are less productive than they could be. Furthermore, if the genetic integrity of the population is eroded through over-exploitation, then the potential for recovery and future abundance is lost.
In other parts of the world, human activities have damaged fish habitats, through pollution, obstruction of migration routes, or ecological disruption. In freshwaters, the introduction of non-native species can be catastrophic for some species (e.g. Nile perch into Lake Victoria). The freshwaters of the Wester Ross Fisheries Trust area remain relatively healthy though many problems have been recognised.
Gyrodactylus salaris [Gs] is a highly contagious parasite that has devastated freshwater salmon populations in parts of Norway. Gs has never been recorded in Scotland. It is native to rivers flowing into the Baltic where fish populations are tolerant of it. Salmon populations in Scotland have no resistance to it and the Scottish Government has recently published a contingency plan to deal with an outbreak should the parasite ever be introduced to Scotland.. The Gs parasite can survive on damp clothing or fishing gear so could enter Scottish river by accident. Please take precautionary measures to prevent contamination if you have been overseas: dry, disinfect or deep freeze all clothing and equipment used outside the country before using it here.

Aaptosyax grypus, Pakse Market February 1997
This may be one of the last photos of Aaptosyax grypus, Rainboth (1991), photographed in Pakse Market in February 1997 by VSO Volunteer, Peter Cunningham. The salmon like cyprinid is (was) an endemic to the middle Mekong River. I also collected a juvenile from a gill net fisherman at ban Hang Khone. Sadly, I have come across no authenticated reports of this unique fish surviving into the 21st Century. Does it still exist? . Posted: 31/03/2010 (196KB)
