Fisheries Research Report No. 365: Recreational Fishing For Marron In South-West Western Australia In 2026, Claire B. Smallwood, Karina L. Ryan, Eva Lai

Fisheries Research Reports

The smooth marron (Cherax cainii) (‘marron’) is endemic to freshwater dams and rivers of south-west Western Australia. Marron are managed as a single stock within the South-West Recreational Freshwater Resource and are highly vulnerable to overexploitation due to the biological characteristics of the species (e.g., low fecundity, localised populations) as well as environmental (e.g., habitat loss, reduction in rainfall) and human (e.g., fishing, land clearing) pressures on freshwater ecosystems.

Due to this vulnerability, this species has been the focus of research, monitoring and management since the 1970’s. Since 2000, annual phone-recall (2000 – 2021) and online-recall (2022 – 2026) surveys …

Developing An Independent Shallow-Water Survey For The Western Rock Lobster Fishery: Tracking Pre-Recruitment Abundance And Habitat Change, Lucy Rudd, Simon De Lestang, Owen Young, Benjamin Hebiton

Fisheries Research Reports

Background

Puerulus settlement has proven to be a good forecaster of legal recruitment of Western Rock Lobster entering into the commercial and recreational fisheries. However, in 2011, this relationship broke down, with average puerulus settlement levels not being reflected in commercial catch rates four years later. Some northern areas showed unexpectedly low catch rates, while other southern areas showed unexpectedly high catch rates. Since this change followed the 2011 marine heatwave, it was assumed that this event changed some component(s) which were important to the growth and survival of juvenile lobsters. It was determined that a better understanding of this …

Books & book chapters

Fisheries managers work with the three components of fisheries—biota, environment, and people - to achieve recreational, stewardship, and socioeconomic goals. Although manipulation of biota and the aquatic environment remains popular (e.g. harvest regulation, protecting or enhancing habitats, and guarding water quality), the human dimension of fisheries must also be considered throughout the fisheries management process. Managers can and should engage fishers in a myriad of ways, from identification of problems to guidance on alternatives, and from measurement of change to evaluation of success. In this chapter, we review common fisheries management goals and objectives; detail information needs stemming from those …
