For some species these large groups may be the only form of reproduction, the high fish numbers briefly giving a false impression of stability and abundance—an ‘illusion of plenty’.?

The strengths and limitations of underwater visual census are now better recognized, and there is improved capacity for fish ageing, especially thro
