Dietary energy/protein ratios for adult Florida Pompano, feed, growth and nitrogen utilization
Selecting a new fish species with a potential value for aquaculture has essential importance for the future development of the aquaculture industry. In the United States, Florida pompano, Trachinotus carolinus, is among the marine fish species with aquaculture potential that has caught the interest of the industry for being a truly euryhaline species. Research is needed to complete our knowledge of the nutritional requirements of Florida pompano at different ages in order to develop cost-effective and environmentally-friendly diets. With the recent interest in high market-value carnivorous species, cost concerns are extremely important since carnivorous fish require greater amounts of protein and fishmeal represents the primary protein source in feeds formulations. A review of the literature confirms the importance of completing the nutritional requirements for Florida Pompano at different ages in the development of cost-effective and environmentally-friendly diets. Our goal was to examine the nutritional requirements in terms of protein and energy for Florida Pompano close to its typical marketable weight, which is between 400 and 600 g. To date, only the nutritional requirements for juvenile fish weighing up to 45 g have been examined. Since nutritional requirements have been well described to change as a fish grows and develops, it is essential that the requirements for larger Pompano, which consume greater quantities of foods than their smaller counterparts, be elucidated. This is most important for protein and lipid levels as they are the most expensive dietary components.
