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...
Groupers (Family Epinephelidae) are commonly caught in data-poor small-scale multi-species fisheries for sale on both export and domestic markets. This study presents data the species composition size/life-stage structure of Epinephelus spp. groupers by fishers sold locally Indonesian province South Sulawesi. Data were collected from fishing ports local markets at 12 sites representing three se...
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...
Systematic check-marks In the sagittal otollths from 6 species of scarids sampled fl-om the Great Bar~ier Reef, Australia, were used to develop size-at-age plots. The species were Chlorurus gibbus, C. sordidus, Scarus frenatus, S. niger. S. psittacus and S. nvulatus. Comparative information for a seventh specles, S. schelgeli, for which otolith increment data \*ere ava~lable. was also included....
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...
