Spawning areas and larval distributions of anchovy <em>Engraulis encrasicolus</em> in relation to environmental conditions in the Gulf of Tunis (Central Mediterranean Sea)

Modelling the presence of anchovy Engraulis encrasicolus in the Aegean Sea during early summer, based on satellite environmental data

“…The related information is generally very scarce regarding the northern African waters. However regarding the Gulf of Tunis published work based on acoustic and egg surveys (Ben Abdallah & Gaamour, 2005;Zarrad et al, 2006) refers that the higher anchovy abundances are mostly located in the south part of the gulf, such as the inshore waters of the gulf of Gabes and the gulf of Sousse, areas that coincide with the locations characterized of high probability of finding anchovy present ([0.5) based on model results.…”

“…1). European anchovy spawning areas and juvenile grounds are also related to the influence of river outflow as shown in the Bay of Biscay, the Adriatic Sea, the Bay of Tunis (Motos et al, 1996;Agostini &Bakun, 2002;Zarrad et al, 2006), in the Catalan Sea and the Gulf of Lions Sabates et al, 2007). However, SSS did not enter the final model most likely because the given range of values of SSS at the best available resolution is very small and insufficient to capture and describe the river influence (Table 1).…”

Comparative Characterization of the Spawning Environments of European Anchovy, <I>Engraulis Encrasicolus</I>, and Round Sardinella, <I>Sardinella Aurita</I> (Actinopterygii: Clupeiformes) in the Eastern Coast of Tunisia

“…No recent data are available on the anchovy eggs distribution and the only single paper was published over 30 years ago by Ktari-Chakroun (1979) who sampled scattered stations along the tuniso-sard and siculo-tunisien channels. There have been some recent contributions dealing with anchovy egg and larval distribution in adjacent areas (Cuttitta et al 2003, García Lafuente et al 2005, Zarrad et al 2006 and on the early life stages of round sardinella (Regner 1977, Tsikliras et al 2005.…”

Distribution of Engraulis encrasicolus eggs and larvae in relation to coastal oceanographic conditions (the South-western Adriatic Sea case study)

“…Anchovy spawning is believed to be related to certain temperature and salinity ranges; for example, in the southern Mediterranean Sea temperatures > 25°C, depth and water stratification are major factors controlling spawning intensity (Zarrad et al, 2006(Zarrad et al, , 2017. In the Benguela ecosystem the spawning temperature ranges between 16 -21 °C (van der Lingen et al, 2001;Twatwa et al, 2005), whereas in the north-western Mediterranean anchovy eggs are mainly found between 17 -23 °C .…”
