Nils: I did my PhD degree on this topic, and I am confident that our fishing quota has no effect on the sustainability of zooplankton. Zooplankton, and especially marine copepods, is thought to be the world’s largest bio-resource of multicellular animals. Globally, the copepods even outnumbers the insects. The Institute of Marine Research in Norway has estimated the production of zooplankton in Norwegian waters to range from 500 to 1000 million tons per year. Considered that landings of the world’s fisheries including aquaculture are 140 million tons per year, it is easy to understand that the zooplankton stock constitute a vast bio-resource. Zooplankton as copepods has typically generation times of more or less than one month in cold water areas, and the stock will easily restore after heavy predation (or harvesting). Zooplankton can potentially solve the demand for protein and fat for the worlds growing population which is projected to increase from 7 to 9 billion people the next 20-30 years. We should, however, perform a precautionary approach for the management of the zooplankton stock, and do research based management for obtaining a healthy ecosystem.
