Indicator: CO-24 Aquaculture: origin species and tonnage of stockfeed used

Data

National data not yet available. The national aquaculture council has developed an action plan consistent with a Fisheries Research and Development Corporation (FRDC) Ecologically Sustainable Development (ESD) framework. Eventually some data may be reported under this strategy.

What the data mean

No data available.

Data Limitations

No data available.

Issues for which this is an indicator and why

Coasts and Oceans — Direct pressure of human activities on coasts and oceans - Pressure of fishing 

Farmed fish are generally provided with other aquatic and marine animals and plants as food, rather than maintained under natural ecological conditions. These feed species may not be native to the area and, if they escape, may compete with or prey on native species, or otherwise degrade the environment. They may also carry diseases or parasites which, if they escape, can impact on the natural ecosystem. Origin species and tonnage of stock feeds are crude indicators of this pressure. They give no indication of escape rates, or what the impacts (if any) would be if they did escape. However, they do give some indication of the potential risk.

Other indicators for this issue:

Biodiversity — Pressures on biodiversity - Pressures on marine biodiversity: pressures of fishing 

Introductions of foreign species from stockfeed for aquaculture activities can place potential pressure on biodiversity. Origin species and tonnage of stock feeds are crude indicators of this pressure. They give no indication of escape rates, or what the impacts (if any) would be if they did escape. However, they do give some indication of the potential risk.
