2020 Western Australian Crop Sowing Guide, Brenda Shackley

Bulletins 4000 -

This edition of the 2020 Crop Sowing Guide includes the major crops grown in WA - wheat, barley, canola, oat and now a new section on lupin and pulses. The publication aims to provide information to support growers with decisions on the best choice of variety for each of the major crops for the upcoming season. The lupin and pulse sections also include an agronomy guide summary to support management decisions required for these high-valued crops.

Statewide Survey Of Boat-Based Recreational Fishing In Western Australia 2017/18, K. L. Ryan, N.G. Hall, E.K. Lai, Claire B. Smallwood, Alissa Tate, S.M Taylor, Brent S. Wise

Fisheries research reports

The statewide survey of boat-based recreational fishing includes three components: (i) off-site Phone Surveys (encompassing an initial Screening Survey, a longitudinal Phone-Diary Survey, and Post-Enumeration Surveys); (ii) on-site Boat Ramp Surveys; and (iii) Remote Camera Surveys. The main data collection period was the 12-months from September 2017 to August 2018 inclusive, with the Post-Enumeration Surveys occurring from September to December 2018.

Invertebrate And Reef Health Research And Monitoring At Cocos (Keeling) Islands – 2019 Update, N Konzewitsch, S. N. Evans

Fisheries research reports

The five long term reef monitoring sites implemented by DPIRD in 2010, and surveyed annually until 2014, were resurveyed in April 2016 and February 2017. In 2016, a sixth monitoring site (site 6) was established in the marine protected area of the Pulu Keeling National Park (PKNP).

Integrated Survey Of Boat-Based Recreational Fishing In Inner Shark Bay 2018/19, S.M Taylor, Claire B. Smallwood, Cameron J. Desfosses, K. L. Ryan, Gary Jackson

Fisheries research reports

Inner Shark Bay is a popular recreational fishing destination. As recreational fishing occurs in a World Heritage Area and Marine Park, there is a need for ongoing reliable information on catches. Many boat-based recreational fishers in inner Shark Bay target Pink Snapper (Chrysophrys auratus).

Recovering A Collapsed Abalone Stock Through Translocation. Seafood Crc Project No. 2011/762, Lachlan W.S. Strain, Jamin M. Brown, Anthony M. Hart

Fisheries research reports

A Roe’s Abalone (Haliotis roei) fishery in Western Australia (Area 8) suffered catastrophic mortality (99.9%) due to an anomalous environmental event in the summer of 2011. During this extreme marine heatwave there was a sustained period of elevated sea surface temperatures that rose to lethal levels for this species and effectively wiped out an entire stock at its northern distribution. Natural recovery within the foreseeable future was considered unlikely, thus providing a unique opportunity to test fishery restoration strategies for abalone. Over the course of this assisted recovery program (5.5 years) no natural recovery was observed in the region most …

Crop And Climate Suitability For Irrigated Agriculture In The Midlands Area Of Western Australia, 2nd Edition, Leon Van Wyk

Resource management technical reports

The Midlands groundwater and land assessment is a $4.7 million Water for Food project. Its aim is to confirm groundwater availability at one or more focus areas that may form precincts of 2000–3000 hectares suitable for intensive irrigated horticulture. This report forms part of this project.

Firstly, this report describes the climate of the Midlands study area and highlights the subtle differences between the two selected focus areas, Irwin and Dinner Hill. It discusses the importance of climate in determining crop suitability. We also investigated the following additional factors that determine crop suitability: water quality, water quantity, land capability (soils) …

Summary Of The West Coast Rock Lobster Managed Fishery Science And Modelling Review, Simon De Lestang, Jason How, Nick Caputi, Emma-Jade Tuffley, Mark Rossbach

Fisheries research reports

An independent peer review of the science and modelling associated with the West Coast Rock Lobster Managed Fishery was undertaken in May/June 2018. The impetus behind this review was two-fold, i) to address industry concerns that stock assessment modelling was not reflecting what was being experienced by fishers on-water, and ii) to increase stakeholders understanding of, and confidence in, the stock assessment process while ensuring that the process was commensurate with contemporary scientific practices.

Development Of An Industry-Based Habitat Mapping/Monitoring System Frdc Project No 2011/021, Simon De Lestang, Matthew B. Pember, Dirk Slawinski

Fisheries research reports

Mapping / monitoring in the marine environment can be a very costly exercise. Scientists from the Department of Primary Industries and Regional Development; Fisheries Division (FD) and the Commonwealth Scientific and Industrial Research Organisation (CSIRO) have developed a small, low-cost automated camera system that, when fitted to commercial fishing gear, can achieve this at minimal cost. The POTBot (Pictures Of The Bottom) system is a cheap, small “smart” camera that can track its position globally and the date and time, and can record high-definition video and water temperature readings when it determines it has been deployed into the ocean.

Status Reports Of The Fisheries And Aquatic Resources Of Western Australia 2017/18. State Of The Fisheries, Daniel J. Gaughan, Brett Molony, 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.
