Trial of the use of new age-pigment-based methods for age determination of western rock lobster (Panulirus cygnus)

The Western rock lobster fishery is a valuable resource in Australia, but it is important to manage it sustainably. One way to do this is to understand the population dynamics, including the age of the lobsters. Traditional methods of measuring age, such as body size, are noy very reliable, so...
