What does science tell us about New Zealand mullet?
Stories of tremendous forest fires, huge storm events, and suffocating heatwaves have dominated headlines over the past few years. We instinctively feel that our weather is getting wilder. Are we finally living through those climate change warnings we’ve heeded for decades?
A marine heatwave is happening all around New Zealand. Warmer waters are more pleasant for swimming in and can create wilder weather. But what do they mean for fishing? Let’s dive into the science behind getting a good catch.
NIWA scientists are doing what no others have done before. In a mysterious world just below the Antarctic ice, a delicate web of ice crystals forms a habitat that’s unique and largely unknown. Until now…

Suspended under these buoys are kilometres of lines, each in turn with their own much smaller lines trailing beneath. These lines, less than a millimetre in diameter, are the anchoring byssal threads (or beards) of green-lipped mussels.
