In early conventional ﬁsheries management, it was suggested that ﬁsheries management should aim to maintain the stock at this point. However, applications of the original ‘surplus yield’ models were limited in their ability to maintain stocks at MSY because they only used catch and effort data and ignored important biological and ecological attributes of individual target species. These attributes ranged from ecosystem and interspeciﬁc interactions to the importance of environmental stochasticity.
Gone’ (eliminated) indicates that the aggregation has not been found in recent years or that catches no longer occur in appreciable numbers. ‘No information’ indicates that no indication on status was available for known exploited aggregations. ‘Same’, ‘Decreasing’ or ‘Increase’ indicate unchanged, reduced or higher catches or CPUE relative to earlier reference points, respectively. Black bars are records from the Indo-West Pacific, white bars the western Atlantic, and the grey bar from the eastern Pacific.
Managers need, therefore, to have a basic understanding of the underlying biological, ecological and socio-economic principles for good management. Another important reason why managers must understand the fundamentals of the species and ﬁsheries they work with is to be able to communicate with others. For example, if ﬁshing communities consider that a trend of declining ﬁsh numbers in their area has occurred because the ﬁsh have ‘decided’ to move somewhere else or into deeper water, and therefore conclude that site-based management in their area is meaningless; a manager should be able to explain what the declines likely indicate and the ways (including site-based) that declines could be addressed.
