“…This situation could explain the differences observed between the sampling sites. Houma et al (2013) and Bahbah et al (2020) confirmed, using different approaches, that Algiers Bay is heavily polluted. In contrast, the waters of Bou Ismail Bay are less polluted (Belkacem et al, 2016).…”

“…In the central region, sampling encompassed four 1C), subjected to anthropogenic pressure due to its touristic and agricultural vocation; Algiers Bay (Fig. 1D), into which several major wadis flow, including El Harrach and El Hamiz, situated in a highly urbanized coastal zone and a site of intense harbour and industrial activities, resulting in significant pollution (Houma et al, 2013). According to Ali and Bachari (2021), chlorophyll a concentrations in Algiers Bay are higher than those measured at other sites in the central region.…”

This study presents an inventory of planktonic cnidarian species collected in Algerian coastal waters (1°10’00” W - 6°52’37” E and 35°37’42” N - 37°01’16” N) from May 2012 to February 2017. The aim was to analyse the qualitative distribution and identify the main components of this gelatinous fauna in different coastal ecosystems in western, central and eastern regions. A total of 60 taxa of planktonic cnidarians were identified, including 57 hydrozoans and three scyphozoans. The class Hydrozoa were represented by 34 hydromedusae, primarily belonging to orders Anthoathecata (15 taxa) and Siphonophorae (23 taxa). Several reported hydrozoan species were recorded for the first time in the southwestern Mediterranean Sea. These new regional records include the hydromedusae Kantiella enigmatica, Leuckartiara octona, Proboscidactylaornata, Cunina globosa, Lovenella cirrata, Cirrholovenia tetranema, Phialella quadrata, Homoeonema platygonon and the siphonophore Forskalia contorta. Seasonal fluctuations were observed in biodiversity, with the highest species richness in spring and summer. The most common species are the calycophorous siphonophores Abylopsis tetragona, Muggiaea atlantica, Lensia subtilis Muggiaea kochii and the holoplanktonic medusae Aglaura hemistoma, Rhopalonema velatum, Solmundella bitentaculata, Liriope tetraphylla and Pelagia noctiluca. The species’ occurrence frequency exhibited seasonal and spatial variability. These distribution patterns were primarily determined by meroplanktonic hydrozoans (Anthoathecata and Leptothecata).

“…This definition made it possible to clarify later, after a good number of debates, the definition of the monitoring objectives. It was at the origin of the extensive definition produced by the Oslo and Paris Conventions (the OSPAR Convention), which constitutes the most current reference: "continuous monitoring is the repeated measure of the quality of the marine environment and of each of its compartments, namely, water, sediment and living environment; natural or anthropogenic activities or inputs that may affect the quality of the marine environment; and the effects of its activities and contributions" [1].…”
