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.

Early axial and appendicular skeletal development of the meagre (Argyrosomus regius). A comparison of two rearing systems

Publication . Valles, E.; Cardeira Da Silva, João; Dionísio, Gisela; Estévez, A.; Pousão-Ferreira, P.; Cancela, Leonor; Gavaia, Paulo J.

The meagre (Argyrosomus regius) is a new species for aquaculture with high economical value, presenting growth rates of 1 kg/year. Skeletal deformities generally appear in cultured larvae at early stages, reducing the value of the fish. The present study describes the osteological development of the vertebral column and fins in meagre larvae. Meagre larvae were obtained from wild broodstocks, kept at IRTA and IPIMAR, and induced to spawn using GnRHa injection.

Development of chondroid tissues in lordotic-kyphotic Senegalese sole (Solea senegalensis)

Publication . Cardeira Da Silva, João; Mendes, A. C.; Pousão-Ferreira, P.; Cancela, Leonor; Gavaia, Paulo J.

Vertebral deformities are frequent and constitute a major drawback for many aquaculture produced species. Lordosis and kyphosis, which are severe curvatures of the vertebral column, are particularly problematic, compromising fish marketing and profitability. Senegalese sole is a species with increasing interest in this industry and, like many others, presents high frequencies of vertebral deformities under rearing conditions.
