Abstract
The work aims to build on that done by Punt and Leslie (1995) in the development of a multispecies model for the two Cape hake species, M. capensis and M. paraodoxus. The authorsaimed to construct a model which included hake, seals and “other predatory fish” and then to use this model to assess the consequences of different levels of consumption of hake by seals on the hake fishery in the context of the change in the size of sustainable hake TACs and catch rates. They also aimed to investigate the effect of seal culling on the fishery.
