Early osteological development and deformities of Diplodus sargus (Linnaeus, 1758) and Diplodus vulgaris (Saint-Hillaire, 1817)

Publication . Gavaia, Paulo J.; Nicolau, L.; Cancela, Leonor; Pousão-Ferreira, P.

Despite the low incidence of morpho-anatomical abnormalities occurring in natural populations, this pose a serious problem for cultivated fish causing increased mortality, reduced growth and conversion rates, thus limiting production and profits. In this study we made an osteological evaluation in the white seabream (Diplodus sargus) and in the common two-banded seabream (Diplodus vulgaris), two sparid species currently under adaptation to intensive aquaculture.

Nutrition, quality and performance in marine fish larvae

Publication . Conceição, L. E. C.; Alves-Martins, D.; Engrola, S.; Gavaia, Paulo J.; Richard, Nadège; Aragão, C.

O cultivo de larvas de peixes marinhos é caracterizado por altas mortalidades e por problemas de qualidade, nomeadamente malformações esqueléticas. A solução de parte destes problemas passa por uma melhor compreensão dos requisitos nutricionais. Este trabalho pretende fazer uma revisão de trabalhos recentes que demonstram como os aminoácidos, os ácidos gordos e a vitamina K, mas também o regime alimentar, podem influenciar a qualidade e a performance das larvas de peixes marinhos.

Fish larval nutrition and feed formulation: knowledge gaps and bottlenecks for advances in larval rearing

Publication . Hamre, Kristin; Yufera, Manuel; Ronnestad, Ivar; Boglione, Clara; Conceicao, Luis E. C.; Izquierdo, Marisol

Despite considerable progress in recent years, many questions regarding fish larval nutrition remain largely unanswered, and several research avenues remain open. A holistic understanding of the supply line of nutrients is important for developing diets for use in larval culture and for the adaptation of rearing conditions that meet the larval requirements for the optimal presentation of food organisms and/or microdiets. The aim of the present review is to revise the state of the art and to pinpoint the gaps in knowledge regarding larval nutritional requirements, the nutritional value of live feeds and challenges and opportunities in the development of formulated larval diets.
