Skeletal quality in Senegalese sole: characterization of fish resulting from en...
Gavaia, Paulo J.; Dionísio, G.; Cardeira, J.; Cunha, M. E.; Pousão-Ferreira, P.; Conceição, L. E. C.; Cancela, LeonorThe Senegalese sole (Solea senegalensis) is characteristic from southern Europe and Mediterranean. It has recently been adapted for aquaculture production since it is well accepted by consumers and reaches high commercial values. After the initial description of the ontogenic events of skeletogenesis, systematic evaluation of the incidence of skeletal malformations by several groups revealed high levels of skel...
Fish larvae quality descriptors: an appraisal of methods for red porgy Pagrus p...
Andrade, Carlos A. P.; Nogueira, N.; Silva, Paula; Cordeiro, Nereida; Cunha, M. E.; Pousão-Ferreira, P.; Ribeira, Laura; Bandarra, N.; Gavaia, Paulo J.Quality control in fish hatcheries is of paramount importance to achieve the desired characteristics of larvae and fry, either for the market or release to the wild. Quality programmes are applied in a day to day basis having direct implications for production management and final costs of product. Most common criteria used for larval quality assessment are morphometrics, condition factor, histometrical indices...
Rearing larvae of dusky grouper, Epinephelus marginatus (Lowe, 1834), (Pisces: ...
Cunha, M. E.; Quental, H.; Barradas, A.; Pousão-Ferreira, P.; Cabrita, E.; Engrola, S.One of the major obstacles to propagating dusky grouper, Epinephelus marginatus, is the difficulty of rearing the early larvae. We have successfully raised dusky grouper larvae in mesocosms using a mixed diet of endogenous plankton grown in the rearing tank and an exogenous supply of Brachionus plicatilis and Artemia sp. Newly hatched larvae at an initial density of 1.3 ind.l-1 were stocked in partially shaded ...
Diet and feeding intensity of sardine Sardina pilchardus: correlation with sate...
Garrido, S.; Ben-Hamadou, Radhouan; Oliveira, P. B.; Cunha, M. E.; Chícharo, Alexandra; Van der Lingen, C. D.Spatio-temporal variability of the diet of sardine Sardina pilchardus off Portugal was examined through analysis of the stomach contents of fish collected every 14 d from the west and south of Portugal during 2003/2004. Dietary composition of the modal sardine length class was assessed by determining the frequency of occurrence and carbon content of identified prey, and these 2 parameters were combined to estim...
