- Environmental Pressures on Wild Atlantic Salmon
This ecological mind map provides a detailed examination of the pressures affecting wild Atlantic Salmon populations. It addresses biological factors such as predation and competition, human influences including fishery practices and renewable energy development, and environmental challenges posed by climate change and habitat modification.

Pressures on wild Atlantic Salmon.
Explotation of Resource
high seas fisheries
in river angling
catch and release
equipment type
temperature infleunces
handling practices
catch and retain
ability to reproduce
mixed stock fisheries
nets
survival
angling
by catch
sea-trout fisheries
Survival at sea/marine mortality
by-catch in pelagic fisheries
predation at sea
parasite burdens
food availability
abundance of prey species
overfishing of prey species
competition
e.g. herring or mackerel
climate change effects
Aquaculture
sea-lice
disease
escapes
genetic integrity
pollution
pollution
damage to benthic habitat
feed sources
Water and sediment quality in rivers
temperature, dissolved oxygen
light levels too high/low
discharges
pollution
acidification of surface water
acid rain
forestry practices
nutrient enrichment
land runoff (e.g. silage, slurry)
wastewater treatment discharges
sedimentation
Land runoff
erosion
overgrazing
Physical barriers to migration
low flows
dams/reservoirs
transport infrastructure
hydo-electricity generation
Climate Change
Freshwater
Changes in water quality e.g., temperature
changes in flow patterns
Marine
increase in water temperature
changes to ocean circulation
changes to prey species
lower nutritional value
availabilty
changes to wind strength
Habitat
physical deterioratation of and/or loss of spawning grounds and nursery habitat
degraded in channel habitats
River flows
historic hill drainage schemes
climate fluctuations
abstraction
e.g. hydro-electricity generation
Interactions with other species
Predation
Marine Mammals
seal
otter
dolphin
harbour porpoise
Piscivorous Birds
Piscivorous Fish
invasive non native species
invasive fish specis
increased competition
increased predation
other invasive species
e.g. North American signal crayfish
e.g. American mink
invasive plant species
potential future effects of beaver introduction
Risk of disease/parasites
including Gyrodactylus salaris
Offshore renewable energy
wave devices
tidal devices
Stocking
Introduction of non native salmon stocks
effects of fitness of wild salmon
