In the marine environment, fish contribute to key ecological processes such as controlling food-webs through top-down impacts, especially on algae. To date, assessment of grazing activity has mostly been performed using short-term (<1 h) censuses by divers or remote cameras which do not allow estimating variability rate within and between days. However, understanding temporal variation hence co...
Global increase in sea temperatures has been suggested to facilitate the incoming and spread of tropical invaders. The increasing success of these species may be related to their higher physiological performance compared with indigenous ones. Here, we determined the effect of temperature on the aerobic metabolic scope (MS) of two herbivorous fish species that occupy a similar ecological niche i...
OBJECTIVE To investigate seasonal variations in tissue phosphorus (P) levels, P to protein ratio, and P to omega-3 fatty acid (ω3-FA) ratio in 2 species of fish that are commonly consumed in Lebanon. We aim to determine suitability for dietary management of renal patients. DESIGN AND SETTING Siganus rivulatus (rabbitfish) and Diplodus sargus (white seabream) were caught in traps off the coast...
