NPI Industry reporting
The purpose of this Emission Estimation Technique (EET) Manual is to assist the Australian Aquaculture industry and State authorities in estimating emissions of listed substances to the National Pollutant inventory. It provides a general overview of the more common temperate water finfish aquaculture methods and describes the procedures and recommended methods for estimating emissions of Category 3 NPI listed substances, specifically total nitrogen (TN) and total phosphorus (TP). These emission estimates must be reported to Environment Australia (EA) by relevant State authorities if annual emissions of N and P exceed 15 tonnes and 3 tonnes respectively.
The species covered by this manual are:
- Atlantic salmon (Salmo salar)
- Trout (Oncorhynchus mykiss and Salmo trutta)
- Tuna (Thunnus maccoyii)
- Silver perch (Bidyanus bidyanus)
- Eel (Anguilla australis)
- Barramundi (Lates calcarifer)
- Seahorse (Hippocampus abdominalis)
- Ornamental Fish
- Other Native Fish
These species have been chosen since they represent the majority of the temperate finfish species currently cultured in southern Australia (Brown et al 1997). The methods described in this Manual are based on the farming methods currently employed for the listed species and may be used as a guide for estimating emissions from other species which use similar farming techniques (See Appendix 1).
