- 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.
- Early skeletal development of meagre (Argyrosomus regius, Asso 1801)Publication . Cardeira Da Silva, João; Nicolau, L.; Pousão-Ferreira, P.; Cancela, Leonor; Gavaia, Paulo J.The meagre (Argyrosomus regius) is a marine teleost with high growth rates and excellent biological characteristics for rearing, making it a proper candidate for diversification of aquaculture in Southern Europe. The description of skeletal development is essential to establish chronometric relationships between skeletal developments, types of ossification, processes and different development stages, contributing to the improvement of rearing conditions.
- Skeletal deformities in larval and juvenile stages of cultured white seabream Diplodus sargus and common two-banded seabream Diplodus vulgarisPublication . Nicolau, L.; Pousão-Ferreira, P.; Gavaia, Paulo J.Species diversification is presently a major concern amongst aquaculture researchers and producers trying to find new profitable species for commercial production and restocking. White seabream Diplodus sargus (Linnaeus, 1758) and common two-banded seabream Diplodus vulgaris (Saint-Hillaire, 1817) are two new promising sparid species for aquaculture production, as an alternative to gilthead seabream Sparus aurata and sea bass Dicenthrarchus labrax, since they present different spawning seasons and good growth ratios.
