The ornamental trade has been growing in the last decade. Traditionally, fish are collected from the wild, causing the destruction of reef habitats and wild populations. Consequently, ornamental aquaculture is a viable strategy to a healthy and sustainable ecosystem. Ornamental fish value is mainly based on skin colour. However, the main problem in reared fish is the loss of colour due to carotenoid deficiency in diets. Therefore, nutrition is a valuable tool to improve quality of the reared ornamental fish. The dietary inclusion of marine biomasses and alternative new ingredients could overcome this situation. The objective of the present study was to assess how innovative diet formulations could improve performance of Amphiprion ocellaris juveniles, as well as to standardize a feeding protocol that promotes fish quality, based on growth and colour. A stock of 180 juveniles were divided in 9 tanks in a recirculation aquaculture system and each diet was assigned to triplicate tanks. Fish were fed by hand to apparent satiety, several times a day, with the respective diets. Diet A contained high levels of traditional marine protein sources and was supplemented with synthetic astaxanthin whereas diets B and C comprised a marked increase of emergent raw materials at the expenses of traditional marine protein sources and without the addition of synthetic astaxanthin. The impact of experimental diets was determined on juvenile key performance indicators at the end of the experimental period. Fish fed with diet A presented a better overall performance nonetheless in the ornamental market the main focus is pigmentation that determines fish value. Consequently, fish fed with diet B presented better results in terms of the desired pigmentation in the fish. Further studies on this topic are required to validate the observed effects over a longer feeding period and over specific phases of the life cycle.
