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:
- CO-16 Status of Australian fisheries
- CO-17 Change in species and trophic structure of fish species caught
- CO-19 Estimated tonnage taken by illegal fishing; estimated number of illegal boats, estimated number of individuals of threatened species taken
- CO-20 Non-target effects: Area of seabeds trawled
- CO-21 Non-target effects: Number and/or weight taken as bycatch, and change since introduction of exclusion devices
- CO-22 Aquaculture: extent of habitat disturbed or removed
- CO-23 Aquaculture: volume of discharged sediments and nutrients
- CO-25 Aquaculture: instances of disease and exotic species introduction from movement of live material
- CO-32 Number of injuries to marine animals from marine debris
- CO-53 Evidence or examples of noise or visual disturbance of marine species by human activities
- CO-62 Estimated number of marine animals harvested by recreational fishers
- CO-63 Estimated number of marine animals harvested by indigenous fishers
- CO-65 Correlation between various human activities and introduction of coastal and marine species
- AAT-19 Annual catch in tonnes of marine species harvested in Australian Antarctic and sub-Antarctic waters - legal and illegal
- AAT-20 Fishing by-catch numbers and/or weight taken as bycatch
- LD-40 Current research into pressures and contributions of naturalised introduced species
- BD-09 The change in extent of selected nationally significant invasive species
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.
