Can commercial harvest of long-spined sea urchins reduce the impact of urchin grazing on abalone and lobster fisheries?

At low-levels of exploitation, commercial harvesting of long-spined sea urchins was found to prevent increase in urchin density. Adjacent unfished locations experienced an increase in both urchin density and grazed area over the 2014 – 2016 study period. Research sampling of populations...

Understanding recruitment collapse of juvenile abalone in the Eastern Zone Abalone fishery – development of pre-recruitment monitoring, simulation of recruitment variation and predicting the impact of climate variation

Over the past three decades the Tasmanian Eastern Zone Abalone Fishery has experienced several fluctuations in catch and catch rates of Blacklip Abalone as well as environmental perturbations, which may be affecting productivity. The capacity to measure inter-annual variation in Blacklip Abalone...

Seafood CRC: quantifying physiological and behavioural responses of cultured abalone to stress events

It is desirable for any primary producer to understand the health and welfare of their stock. This will ultimately enable optimal production and return on investment. The challenge in any aquaculture system is ‘observing’ the physiological and behavioural responses associated with environment,...

Monitoring abalone juvenile abundance following removal of Centrostephanus and translocation

A new system of Abalone recruitment modules (ARMs) have proven to be successful in collecting juvenile abalone in Tasmanian waters. This design was subsequently transferred to the Eastern Zone, Victoria, where IMAS staff and Eastern Zone Abalone Industry Association (EZIZA) members installed ARMs at...
