student will be able to 1.2.4 analyse the effects of Invasive Alien Species in fisheries
Effects of aquatic Invasive Alien Species on Fishery habitat - Spread to cover water surfaces
-
Decrease light penetration - Reduction of oxygen content in water
-
Increase acidity of water - Sedimentation through decaying
- Rapid water
loss due to transpiration -
Fishery Organisms - Blurred vision
offish due to turbid water - Reduction in growth due to acidity of the water
- Poor respiration due
to low oxygen level of water Students to Discuss the effects of aquatic Invasive Alien Species on fishery habitats,
fishery organisms, fishers,
