Key Takeaways
- Rob Pennicott, a tourism operator and local, has noticed significant changes in the D’Entrecasteaux Channel over the past 25 years, including fewer abalone and lobster and areas devoid of life.
- Pennicott’s philanthropic foundation has given $900,000 to scientists to conduct a five-year study on the channel’s underwater environment.
- The study aims to provide evidence on the impact of salmon farming and other factors on the channel’s ecosystem.
- Scientists believe that long-term monitoring is crucial to understanding the changes in the channel and making informed decisions.
- The study will cover a larger area than previous monitoring programs and will use underwater cameras to survey reefs across the waterway.
Introduction to the D’Entrecasteaux Channel
The D’Entrecasteaux Channel, located between Bruny Island and mainland Tasmania, is a unique and diverse ecosystem that has been affected by significant changes over the past few decades. Rob Pennicott, a local tourism operator and avid snorkeller, has witnessed these changes firsthand and is concerned about the future of the channel. With over 25 years of experience running boat tours in the area, Pennicott has noticed a decline in the number of abalone and lobster, as well as areas that appear to be devoid of life. These observations have prompted Pennicott to take action and seek answers about the causes of these changes.
Concerns about the Channel’s Ecosystem
Pennicott’s concerns about the channel’s ecosystem are shared by many locals and scientists. The channel is home to a variety of marine life, including abalone, lobster, and fish, but the decline of these species has raised concerns about the health of the ecosystem. Pennicott has described areas of the channel as "dead zones," characterized by a lack of life and a dark, sludgy appearance. These changes have not only affected the environment but also the local community, with many people expressing concern about the impact of salmon farming and other human activities on the channel.
The Role of Salmon Farming
Salmon farming is a significant industry in Tasmania, with many farms located in the D’Entrecasteaux Channel. While some people argue that the changes in the channel are natural, others blame the salmon-farming industry for the decline of marine life. Pennicott is unsure about the cause of the changes and wants evidence to support any claims. He has met with salmon farm representatives, who suggest that agriculture and global warming may be contributing factors. However, Pennicott believes that it is essential to find the truth and work with the evidence to achieve better results.
The Importance of Long-Term Monitoring
Jeff Ross, a senior scientist with the Institute for Marine and Antarctic Studies (IMAS), emphasizes the importance of long-term monitoring in understanding the changes in the channel. Ross notes that monitoring has not kept up with the expansion of salmon farms in the channel, making it challenging to provide evidence to decision-makers. The lack of baseline studies has made it difficult to understand the impact of human activities on the channel’s ecosystem. Ross believes that the study funded by Pennicott’s foundation will provide valuable insights into the channel’s ecosystem and help inform decision-making.
The Study and its Objectives
The five-year study, which is already underway, aims to survey reefs across the waterway using underwater cameras. The study will cover a larger area than previous monitoring programs and will provide a holistic understanding of the channel’s ecosystem. The team, led by Camille White, will investigate the impact of salmon farming and other factors on the channel’s ecosystem. The study will also examine the presence of bright green algae, a weed that locals and scientists are concerned about. White believes that the study will help answer questions about the changes in the channel and provide evidence to support decision-making.
Conclusion and Future Directions
The study funded by Pennicott’s foundation is an important step towards understanding the changes in the D’Entrecasteaux Channel. The research will provide valuable insights into the channel’s ecosystem and help inform decision-making. Pennicott is hopeful that the study will help answer questions about the causes of the changes and provide a way forward for protecting the channel. The study’s findings will be crucial in developing strategies to mitigate the impact of human activities on the channel’s ecosystem and ensure the long-term sustainability of this unique and diverse environment.
