- The Oceans and Fisheries Minister, Shane Jones, has expressed concerns about fish migrating to the South Island due to warming waters.
- The rate of warming in ocean waters around New Zealand is 34% faster than the global average warming rate, according to the Our Marine Environment 2025 report.
- The Ministry for Primary Industries (MPI) is considering the impact of climate change on fish stocks and the fishing industry, including the potential for regulatory changes.
- The government is working to balance the needs of the fishing industry with the need to protect the environment and conserve fish stocks.
- Climate change is having a significant impact on the fishing industry, with some fish species moving to cooler waters in the South Island.
Introduction to the Issue
The Oceans and Fisheries Minister, Shane Jones, has raised concerns about the impact of warming waters on the fishing industry in New Zealand. During a recent hearing before the Primary Production select committee, Jones discussed the issue of fish migrating to the South Island due to changing ocean temperatures. This shift in fish populations is having a significant impact on the fishing industry, with some species moving to cooler waters in the South Island. Jones noted that in his lifetime, he has seen a significant change in the distribution of fish species, with some species that were previously found only in the North Island now being caught in the South Island.
The Impact of Climate Change
The Our Marine Environment 2025 report found that the rate of warming in ocean waters around New Zealand is 34% faster than the global average warming rate. This warming is having a significant impact on the fishing industry, with some species experiencing "shifts in their home range and overall productivity". The Ministry for Primary Industries (MPI) is considering the impact of climate change on fish stocks and the fishing industry, including the potential for regulatory changes. The director of primary sector policy, Alastair Cameron, noted that some fisheries are moving further south into cooler waters, and that the MPI is working to understand the complex and developing issue of climate change and its impact on the fishing industry.
Regulatory Responses
Jones has instructed officials to look at how to "cope" with the changing fish populations, including the potential for regulatory changes. The MPI is considering how to make the regulatory system more agile and flexible to account for the changes that are being seen in the fishing industry. Jones noted that the fishing industry has asked for help in dealing with the changing fish populations, and that he has instructed officials to look at how to provide support. The government is working to balance the needs of the fishing industry with the need to protect the environment and conserve fish stocks.
Public Favor and Decision-Making
Jones also discussed the issue of public favor when it comes to managing primary industries. He noted that the government has "shifted the pendulum" so that climate change is no longer regarded as a polarizing, ideological issue. However, he also acknowledged that the public is not "of one mind" on the issue, and that decisions must be made with careful consideration of the potential impacts. The government is working to make decisions that are based on science and that take into account the needs of the fishing industry and the environment. For example, an upcoming decision is expected to stop the access of recreational and commercial people in New Zealand from taking crayfish from the entirety of Northland’s east coast.
Conclusion and Next Steps
In conclusion, the issue of fish migrating to the South Island due to warming waters is a complex and developing issue that requires careful consideration and regulatory responses. The MPI is working to understand the impact of climate change on the fishing industry, and the government is working to balance the needs of the fishing industry with the need to protect the environment and conserve fish stocks. The next steps will involve continuing to monitor the situation and making decisions based on science and the needs of the fishing industry and the environment. Jones noted that he is concerned about the potential impact of climate change on the fishing industry, but that he is also committed to finding practical solutions that work for everyone involved.
