Diseases affecting our aquatic species

This document describes the sources of information, advice, methods, indicators and data processing procedures used to develop the reports. Reliability of data, as well as metadata attributes, are also described.

State NRM Plan Guiding Target:

Limit the establishment of pests and diseases and reduce the impact of existing pests State NRM Plan Representative Measure:

Number of detections of weeds, other pests and disease incursions and reduce the impact of existing pests Data collection period:

1978–2016.

Expected frequency of reporting:

Annual.

Data sources:

1. Records and reports of notifiable aquatic animal diseases are from the Department of Primary Industries and Regions SA (PIRSA) and Aquatic Animal Health and Quarterly aquatic animal disease reports.

2. Information on diseases affecting marine mammals was obtained from the South Australian Museum.

Indicators used:

1. Number of priority fish and shellfish diseases which are recorded each year. Priority diseases includes those which are liste d, or have been listed as notifiable in the South Australia Livestock Act and from Animal Health Australia.

2. Summary of recent disease or mortality events (e.g. fish kills, aquatic animal deaths).

Methods of data collection and processing:

Records of notifiable disease detections were obtained directly from PIRSA and/or from Quarterly Aquatic Animal disease reports.

Data were summarised by the number of priority diseases which were detected in South Australia by financial year.

Future reporting measures:

Future reports may highlight different diseases depending on current issues.

The following government agencies contributed to this report:

PIRSA, Department of Environment, Water and Natural Resources (DEWNR), SA Museum.

The following non-government agencies contributed to this report:

None.

Key stakeholders:

DEWNR, NRM Council, NRM Boards, PIRSA, Biosecurity SA, fisheries and aquaculture industries, public.

Information reliability scoring:

Information is scored for reliability based on average scores given for information currency and applicability, and its level of spatial representation (Tables 1–3).

Table 1. Information currency Reliability Criteria

5 Information up to 3 years old 4 Information up to 5 years old 3 Information up to 7 years old 2 Information up to 10 years old 1 Information >10 years old

Table 2. Applicability of the information Reliability Criteria

5 All data based on direct indicators of the measure 4 Most data based on direct indicators of the measure 3 Most data based on indirect indicators of the measure 2 All data based on indirect indicators of the measure 1 Data are based on expert opinion of the measure

Table 3. Spatial representation of information (sampling design) Reliability Criteria

5 Information is collected from across the whole region/state (or whole distribution of asset within the region/state) using a stratified sampling design

4 Information is collected from across the whole region/state (or whole distribution of asset within the region/state) using a sampling design that is not stratified

3 Information is collected from an area that represents less than half the spatial distribution of the asset within the region/state

2 Information is collected from an area that represents less than 25% the spatial distribution of the asset within the region/state

1 Information is collected from an area that represents less than 5% the spatial distribution of the asset within the region/state or spatial representation unknown

Based on tables 1, 2 and 3 above, respectively, the information relating to condition presented in this report has a reliability score of (5+4+1)/3 = 3.33 rounded to 3 (Good).

This report is linked to the following report cards/snapshots:

1. What are the distribution and abundance of pest animals?

2. What are the distribution and abundance of weeds?

3. What are the distribution and abundance of aquatic pests?

4. Diseases and invertebrate pests affecting our crops.

5. Diseases affecting our native plants and animals.

6. Diseases affecting our livestock.
