The current focus on BIODIVERSITY has arisen from the recognition that human activities are having serious impacts on the world’s environments and the millions of species populating them. It is NOT possible to develop an effective strategy for conserving the species that are left - especially if we are to continue to use some for the benefit of humans - without knowing what species are to be managed and without having a way of talking about them. Scientists recognise that each species differs in some way from every other and that each has its own peculiar requirements for continued existence.

Fisheries are one of the few methods of food production today which are based on natural populations of animals in the 'wild'. Management of fisheries relies on understanding these natural populations. Even with our vastly improved knowledge about the species we are fishing, problems still arise. Sometimes, scientists and fishery managers do not fully understand whether they are dealing with one or more species in a particular fishery. The gemfish fishery in New South Wales is an example.
