Distribution and mixture of Cape and Cunene horse mackerel, Tachurus capensis and Tracherus trecae in the Angola-Benguela front in relation to environmental and other factors
type: CreativeWork
description: This thesis makses an analysis of survey data of horse mackerel catch per unit effort and acoustics data from R/V Dr. Fridtjof Nansen over twelve years in the region of the Angola-Benguela front. The main objectives are: to characterize the pattern of distribution and mixture of Cunene and Cape horse mackerel in the area around the Angola-Benguela front and to study the relationships between the distribution of T. capensis and T. trecae and the movements of the Angola-Benguela front. The role of sea surface temperature (SST) was also examined, assuming that this environmental parameter would be related to the seasonal variation in distribution of both species of horse mackerel, at least in the overlap area.
