The Guinean Fingerfish Monodactylus sebae is a popular euryhaline ornamental fish species with limited aquaculture production. One of the bottlenecks to commercial production is lack of knowledge of the nutritional requirements for broodstock. Therefore, three broodfish diets were formulated and fed to Guinean Fingerfish broodstock to determine their quantitative and qualitative effects on egg production and egg and larval morphology. The dietary treatments consisted of a control, a diet with increased docosahexaenoic acid (DHA), and a diet with increased DHA and arachidonic acid (DHA + ARA). Broodfish fed the DHA + ARA diet spawned more frequently than broodfish fed the DHA diet and those fed the control diet. The greatest egg production was also observed from broodfish fed the DHA + ARA diet. The mean hatching success of floating eggs was not significantly different among diets. The mean egg and oil globule diameters for both floating and sinking eggs were significantly smaller for broodfish fe...
