A study of 20 healthy young male volunteers confirmed the existence of a quantitative and temporal relationship between food and fluid intake, and assessed the effects of fluid restriction on food acceptability and intake under scheduled eating conditions. Fluid restriction and thirst were significantly correlated with a reduction of food intake. Possible explanations of the relation between food and fluid intake are discussed.

Arvicola terrestris Scherman est un rongeur fouisseur dont le regime alimentaire n'a ete que tres peu etudie bien que les degats qu'il occasionne dans les prairies soient tres importants, surtout lors des pullulations cycliques. Les methodes classiques d'investigations (analyses des contenus stomacaux, des reserves alimentaires, etc) ne rendent que partiellement comptes des choix reels. En outre, les travaux effectues sur le terrain ne permettent pas de tirer de conclusions precises sur le sujet, notamment en raison de la grande diversite des especes vegetales presentes. C'est pourquoi nous avons choisi une approche experimentale: un "essai en pature" adapte aux campagnols. L'experience s'est deroulee dans un terrarium de 6 x 3 m, dispose en pleine terre. Les campagnols places dans le terrarium avaient le choix entre 12 plantes, cultivees separement sur de petites parcelles. Ils pouvaient se nourrir, soit en surface, soit a partir de leurs galeries souterraines et restaient ainsi dans des conditions proches de celles de la prairie. Les preferences ont ete deduites selon trois methodes: la comparaison des quantites de matiere seche recoltees dans le terrarium et dans un temoin identique, l'observation des signes d'activite des campagnols et l'evolution du recouvrement de la vegetation dans chaque parcelle. Les trois ont donne des resultats semblables. Ce premier essai realise en 1986 a permis de mettre en evidence une nette preference pour Medicago sativa, Taraxacum officinale et Trifolium pratense; aucune des graminees presentees n'a ete tres appreciee malgre leur bonne qualite fourragere

Food composition of Abramis brama was studied in the shallow, meso-eutrophic Hamry reservoir (Czech Republic). Fish were sampled during the daytime in the pre-spawning period (April), the post-spawning (June), summer (July) and autumn (October) in 2011. The bream sampled comprised two main size groups: small (124-186 mm) and large (210-315 mm) standard length. Twenty specimens of each size group (except April - 40 large fish) were taken for analysis on each sampling occasion. Food composition was evaluated using gravimetric methods. Over the whole season, detritus and aquatic vegetation were the dominant dietary items taken. During summer, the diet of large bream comprised mainly aquatic vegetation. Benthic macroinvertebrates and zooplankton formed a minor part of bream diet over the whole season. Specific food habits of bream could be explained by specific conditions within the reservoir and available food resources.

Commercial fish landing at Abu Qir and Alanfoushy markets was the source of Siganus rivulatus and Siganus luridus sampled for food and feeding habits analysis. Food indices and food content were studies in stomach analyses of 1485 fishes

The spawning season and food habits of the deep-water stomato-pod crustacean Squilloides leptosquilla (Squillidae) were examined using samples collected on board the small-scale bottom trawlers in Kagoshima Bay, southern Japan. From the reproductive analyses, the size at sexual maturity of female S. leptosquilla was estimated to be 10 mm in carapace length and the spawning season was estimated to continue from May to September with a peak during July and September. Gut analysis showed that this species is a typical carnivore and mainly ate shrimps, especially the deep-water mud shrimp Solenocera melantho which is one of the most important target species for the small-scale bottom trawlers in Kagoshima Bay.
