One of the biggest challenges in commercial marine warmwater finfish production is consistent high-quality eggs, to ensure a steady supply of seedstock. A sufficiently nutritious broodstock diet is needed because a maternal diet would greatly influence the survival and development of the offspring. Florida Pompano (Trachinotus carolinus) is a coastal species common to Florida coasts with growing interest for commercial aquaculture production. The objective of this study was to evaluate the impact of different diets of the Florida Pompano broodstock, such as the control diet (cut-bait shrimp), commercial Breed-M and the green seaweed Ulva-based diet, on the quality of eggs, specifically the fertilization and hatching rate, the growth rate, the use of endogenous nutrients, and the fatty acid profiles of embryos and larvae during the endogenous and exogenous feeding period. The experimental design includes 40 fish evenly distributed in 4 tanks of 2.5 m in diameter (7.8 m3) installed in identical Recirculating Aquaculture Systems (RAS). Broodstock in each tank were fed the same diet 4 times a day at 10 % of the fish body weight. At the time of spawning, after each diet treatment, eggs from each tank were incubated in 4 replicates. Eggs were taken for biochemical analysis and frozen at -80°C from each incubator and fresh samples were placed under the microscope for morphological measurements. It is expected that the addition of Ulva in the feed would provide sufficient nutrient levels for quality eggs and larvae comparable to the experimental diets and produce a similar or higher yield than the control and Breed-M diets.
