WebJan 5, 2024 · Fish ageing is the quickest and easiest way to assess fish growth and mortality rates. It also allows us to determine when fish mature and how well species are recruiting within a population. This is key information, essential for underpinning fishery management practices such as stocking or cropping. WebThe age information collected in the monitoring program has been used to construct an age-at-length graph for snapper (see age-at-length graph). After measuring the total length of your fish, you can estimate its age using the age-at-length graph. For example a 65 cm snapper is likely to be nine years old but it could easily range from 5 to 13.
