| Monthly variability of zooplankton and ichthyoplankton abundance and composition were studied in 6 stations in the Gulf of Tunis between February 2003 and January 2004. Plankton trawls were horizontal, in surface and at night. Study area seems to be influenced by climatic conditions and the outflow of Majreda River that affect the surface temperature and salinity. Copepods, with many abundance picks in the year, formed the most abundant group (84%) followed by cladocerans (8%) and chaetognaths (3%). The swarms of appendicularians, cladocerans and medusas then for zoe are in spring. The highest fish spawning periods was in summer then the highest larva abundance was in winter and summer. |

| Pendant l’été et l’automne de l’année 2002, deux campagnes d’étude de l’ichtyoplancton ont été effectuées dans le golfe de Tunis. La température moyenne des eaux de surface a été de 25,51°c en été et 21,85°c en automne. Les œufs et les larves ont été plus abondants en été qu’en automne (360 œufs /10m² et 244 larves /10m² en été et 115 œufs /10m² et 174 larves /10m² en automne). Les paramètres environnementaux : température, salinité oxygène dissous, pH, chlorophylle a et abondance du mésozooplancton ne semblent pas avoir une influence directe sur la distribution spatiale de l’ichtyoplancton. Cependant, la bathymétrie semble avoir une influence sur cette distribution. |

| In the setting of a program of census and identification of cetaceans in the Tunisian waters, started in 2001 by a pilot campaign limited to the region of the Sahel (of Sousse to The Chebba), the INSTM (National Institute of Sea Sciences and Technologies of Tunisia) and the CRC-Marineland (Center of Research on the Cetacean Antibes, France) achieved a second prospecting campaign from the first to May 28, 2003. This campaign, baptized « ASPIS 2003 », concerned the zone of the 15 MN of Kélibia to Zarzis, in the east and the south of the country. The north zone has not been prospected practically following bad weather. The density of the common bottlenose dolphin <Tursiops truncates> has been estimated to 0,19 animals/km2, with a coefficient of... |
