| To examine the factors that may be the cause of te strandings of te jellyfish Pelagia noctiluca (Försskal,1775), in the coast of Tetouan (Moroccan Mediterranean coastline), a monthly monitoring was done in 5 sites (Oued Lau, Sidi Abdesslam, Martil, Cabo-negro, M'diq) from 2011 until 2015; Jellyfish outbreaks is a natural phenomenon observed in many populations of marine ecosystems (Hammer et Dawson 2009). Since the 70s, Pelagia noctiluca is considered one of the most common species in the Mediterranean Sea (Goy et al., 1989; Rosa et al., 2013). This outbreaks of jellyfish is considered by some authors as a result of climate change (Duarte, 2013), since 2011 we have noticed that there is more jellyfish (Pelagia noctiluca) in the Mediterranean coast of Morocco this jellyfish is a real danger that threatens our environment. In 2011 the Mediterranean coastline of Morocco (more exactly the north west of the coastline) have known an invasion of a large number of the jellyfish Pelagia noctiluca we didn't know the causes of this blooms that's why our goals is to understand well the causes and the impacts of tis outbreaks. |
