Monitoring of Porpoise Stocks: 1986 to 1990

SpottedDolphins


In 1986 the US National Marine Fisheries Service (NMFS) initiated a long-term, large-scale research program to monitor trends in the abundance of dolphin populations in the eastern tropical Pacific (ETP). The program utilized two research vessels annually for 120 days each, from 1986 to 1990, for a total of five surveys. Although the purpose of the surveys was to monitor dolphin abundance, sightings of all cetaceans were recorded. These surveys provided a unique opportunity to describe the abundance of the entire cetacean fauna in the ETP. The surveys were known under the acronym MOPS, Monitoring of Porpoise Stocks.
