A total of 491 stomachs from 16 teleost species was analyzed. The analysis revealed spatial variability (East under marine influence and West with more continental effect) and temporal one (wet and dry seasons). Based on stomach contents, nine trophic groups were revealed, including eight monospecific groups. The main prey are mudflat snails (Hydrobia ventrosa, H. acuta), bivalves (Abra alba, Cerastoderma glaucum), amphipods and isopods, as well as seagrass (Potamogeton pectinatus, Ruppia cirrhosa) and water brackish algae (Ulva spp. and Chaetomorpha spp., Cladophora sp., Polysiphonia sp.). specialized Ichthyofauna Tunisia Ichkeul Lake Stomach contents Prey Diet Trophic group TUNISIE ICHKEUL LAC 036 39 3 193-210 2015 0399-0974 https://www.documentation.ird.fr/hor/fdi:010065635 0399-0974 [F B010065635] https://www.documentation.ird.fr/hor/fdi:010065635 https://www.documentation.ird.fr/intranet/publi/depot/2015-12-17/010065635.pdf Accès réservé (Intranet de l'IRD) IRD - Base Horizon / Pleins textes 2015-12-04 2017-08-23 fdi:010065635 fre
