Fish Ageing

Fish ageing is a process of determining the age and growth of a fish. Ageing can be done using various techniques such as scale and otolith (ear bones) readings, and chemical and structural properties of the bones. Ageing can be used to provide insight into the growth and mortality of a fish population, and can provide information such as mean lifetime, growth rate, and longevity. Furthermore, fish ageing is also used to determine the sex ratio and age composition of a population, as well as to understand the causes of recruitment into a population. Fish ageing is an important tool in fisheries management for assessing and managing fish stocks, as well as for monitoring the health of the environment.
