Ecological Risk Assessment For The Temperate Demersal Elasmobranch Resource, Maddison Watt, Matias Braccini, Kim Smith, Mathew Hourston
Ecological Risk Assessment For The Temperate Demersal Elasmobranch Resource, Maddison Watt, Matias Braccini, Kim Smith, Mathew Hourston
Fisheries research reports
In March 2021, the Department of Primary Industries and Regional Development convened an ecological risk assessment (ERA) of the fisheries that access the Temperate Demersal Elasmobranch Resource. The ERA considered the potential ecological impacts of the Temperate Demersal Gillnet and Demersal Longline Fisheries and recreational fishers who catch sharks and rays. The assessment evaluated the impact of each fishing sector/method on all relevant retained and bycatch species, endangered, threatened and protected species, habitats and the broader environment.

Fisheries research reports
A recovery program for the West Coast Demersal Scalefish Resource was introduced between late 2007 and early 2010, based on the maintenance of retained catches of demersal species (overall suite and each indicator species) by both the commercial and recreational sectors below 50% of the catches reported in 2005/06 (original catch recovery benchmarks).
Catch reductions were aimed at reducing exploitation levels (F, long-term fishing mortality of the key indicator species’ stocks) to below the threshold reference point (F = M, the natural mortality rate), which would then allow stocks to recover to above the …

Otoliths Of South-Western Australian Fish: A Photographic Catalogue, Chris Dowling, Kim Smith, Elaine Lek, Joshua Brown
Fisheries research reports
Due to the species-specific nature of otoliths and given they are often the only part of the fish preserved when fish die, otolith catalogues can be used in numerous applications, such as diet studies in fish eating animals, including pinnipeds, fish and sea birds; archaeological purposes such as reconstructing indigenous people’s diets from otoliths found in middens or evolutionary history of fish species by comparing fossilized otoliths. Given the unique mixture of subtropical and temperate fish, including many endemic species that occur off the southwest corner of WA having a catalogue for this area is extremely important for people working …

Mosaic Agriculture: A Guide To Irrigated Crop And Forage Production In Northern Wa, Geoff A. Moore Mr, Clinton K. Revell Dr, Christopher Schelfhout Dr, Christopher Ham Mr, Samuel Crouch Mr
Bulletins 4000 -
The Bulletin is a comprehensive guide for pastoralists, agronomists, agribusiness and the broader community on the growing of irrigated crops and pastures within a rangeland pastoral setting.
Dispersed irrigation developments on stations throughout the northern rangelands (sometimes referred to as mosaic agriculture) has created opportunities for the introduction of more productive forage species and pastoralists can now grow high quality forage for 12 months of the year. This can help to overcome the key constraint of traditional pastoral systems, the low quality of the feed over the dry season that typically results in stock losing condition.

Status Reports Of The Fisheries And Aquatic Resources Of Western Australia 2019/20. State Of The Fisheries, Daniel J. Gaughan, K. Santoro
Status reports of the fisheries and aquatic resources
The Status Reports of the Fisheries and Aquatic Resources of Western Australia (SRFAR) provide an annual update on the state of the fish stocks and other aquatic resources of Western Australia (WA). These reports outline the most recent assessments of the cumulative risk status for each of the aquatic resources (assets) within WA’s six Bioregions using an Ecosystem Based Fisheries Management (EBFM) approach.
