Finding the balance...
Aquaculture species require optimal water quality to survive, remain healthy and grow. Therefore the success or failure of an aquaculture operation is dependant upon water quality management. The key to successful aquaculture maintenance lies in the aquaculture farmers’ ability to regulate algae and prevent blue green algal blooms.
Performance declines once blue-green algae develop and excessive algal growth occurs.
Blue-Green Algae Prevention: A Challenge Faced By Aquaculture Farmers
Large amounts of fish or prawn stock are necessary for profitable commercial aquaculture. As a result ponds receive large levels of nutrient inputs from uneaten feeds and excretion. Phosphorous makes up a large portion of nutrients. Whilst nutrients are necessary to maintain suitable water conditions for aquaculture species, high levels can lead to the growth of harmful algae.
This has serious ecological, aesthetic and financial implications.
