Lomond supports several important fish species, the status of
which is giving cause for national and international concern.
surveys are allowing us to monitor changes in salmonid fish distribution
and abundance across the catchment. This information provides
an indication of the health of the system and can be highlight
problems such as habitat degredation. Work is also being conducted
on other locally important species native to Loch Lomond including
powan, pike and lamprey.
surveys are being undertaken and combined with information on
land use, hydrology and geology to build up a picture of the condition
of the environment throughout the catchment area. This information
will be used to identify areas of poor habitat and to target restoration
and enhancement work.
programmes are aimed at identifying underlying causes of change
in fish popultaions. LLFT is currently involved in work to assess
the genetic make-up of salmon popultaions in different parts of
the Lomond system. This is important in helping to identify pressures
on different stocks and to promote sustainable fisheries management.
freshwater environment is critical to the life cycle of all fish
populations. Salmon and sea-trout require high quality streams
with unimpeded access to and from the spawning areas. Pike in
contrast require shallow bays with dense aquatic vegitation in
which to spawn. Ensuring the best possible habitat is available
is fundamental to maximising fish production. Once habitat surveying
is completed, a practical programme of habitat enhancement is
planned to restore impacted areas. This will include bank protection
to mitigate against the effects of erosion and removal of obstructions
to ensure migratory fish get free passage to their spawning grounds.
