About the research project

Discover the Fascinating World of Abalone in Tasmania!

Did you know that Tasmania is responsible for 25% of the world's wild-caught abalone? This tiny island is a global leader in abalone production, but it's also at the forefront of marine science. It faces unique challenges like marine heatwaves caused by climate change and harmful algae that produce paralytic shellfish toxins (PSTs). These toxins can build up in abalone, creating serious health concerns for both people and animals and posing risks to the abalone market.

To protect this valuable fishery, scientists are diving into key questions. This project focuses on:

  1. Understanding Toxin Retention
    - Why do some toxins stay in abalone tissues longer, and what does this mean for food safety and exports?
    - How do toxins in abalone differ based on location, tissue type (like foot vs. viscera), and algae bloom sources? 
    - Is there a process where toxins are altered within abalone tissues
  2. Exploring Toxin Longevity
    - Are toxins in abalone foot tissue staying longer because of slow detoxification or ongoing exposure?
    - Fieldwork will track algae cysts in abalone habitats and study toxin levels over time.
    - Experiments will monitor abalone kept under controlled conditions to study how long toxins persist.
  3. Investigating Animal Health Impacts
    - How do toxins affect the health and reproduction of adult and juvenile abalone?
    - With climate change as a backdrop, experiments will combine toxin exposure with rising temperatures to simulate future conditions.

This research is uncovering the mysteries of abalone biology and helping to secure their future in a changing world. If you're curious about marine ecosystems, sustainability, and how science can drive solutions, this project offers an exciting glimpse into groundbreaking marine research.
