    Item type: Journal Article • Journal: African Journal of Marine Science
    Recent changes have been observed in South African marine ecosystems. The main pressures on these ecosystems are fishing, climate change, pollution, ocean acidification and mining. The best long-term datasets are for trends in fishing pressures but there are many gaps,...
  2. Changes in the trophic structure of the southern Benguela before and after the onset of industrial fishing

    Changes in the trophic structure of the southern Benguela before and after the onset of industrial fishing

    Item type: Journal Article • Journal: African Journal of Marine Science
    Despite a human presence in the Benguela region for at least one million years, exploitation of marine resources by European seafarers only began in earnest in the 1400s. Ecopath with Ecosim was used to construct and compare mass-balanced foodweb models...
  3. Changes in the trophic structure of the northern Benguela before and after the onset of industrial fishing

    Changes in the trophic structure of the northern Benguela before and after the onset of industrial fishing

    Item type: Journal Article • Journal: African Journal of Marine Science
    Exploitation of marine resources has been occurring in the northern Benguela ecosystem for centuries.
