A current research by oceanographic specialists monitored the migration of sardines from Mauritania and Senegal to the coast of Morocco between 1995 and 2015 resulting from rising temperatures within the Atlantic Ocean.
The research, revealed within the scientific journal Nature, exhibits that the Cap Nouadhibou area in Mauritania kinds a transition zone for the migration of golden sardines and madren sardines, fish primarily eaten by residents of northwest Africa.
Fishermen report that the migration of sardines from Senegal and Mauritania to the north (on the coast of Morocco) has resulted in vital declines in sardine numbers over the previous 20 years.
The research, titled “Impression of local weather change on the distribution of small pelagic fish species in northwest Africa: Traits, modifications and dangers to meals safety,” famous that the decline was additionally linked to intensified fishing exercise throughout the 1995-1995 research interval. In 2015, by comparability, fishing stress and forage fish biomass had been much less carefully associated in another areas.
Specialists clarify the rationale for this migration as “environmental modifications, particularly a big enhance in ocean temperatures off the coasts of Mauritania and Senegal, which straight impacts the migration of sardines and their way of life.”
As for the temperatures that kind the primary topic of the research, the specialists are properly conscious that “the coasts of Senegal and Mauritania are getting hotter, coinciding with the rise of the Atlantic seafloor”, which signifies that the Cape Blanc area (Cape Nouadhibou ) is taken into account to be the transition zone of the ocean floor layer; it’s characterised by an everyday rise in sea floor temperature, secure backside water, and apparent anomalies in sea floor temperature all year long.
