What is it about?
There is a large inequality in the catch distribution amongst anglers. We explored if this inequality has changed over time, if it was related to the abundance of fish, and which type of anglers was responsible for the inequality. We also explored if the CPUE was related to the fish abundance and discovered that the Taupo Fishery in New Zealand shows clear sign of hyperstability.

Why is it important?
Our work indicates that it could be very misleading to use CPUE as a measure of the health of the fishery. It also indicates that the inequality in catch distribution goes up when the fish population goes up, therefore, adding more fish in the system will not make the distribution of catch more equitable.
Perspectives
Participation to recreational fishing is declining in many parts of the world and trying to slow down the process is paramount. This study reveals that even a higher CPUE has not reversed the trend in participation. Some new tools are urgently needed.
