  1. Comparative Behavior of Wild and Hatchery Reared White Sea Bream (Diplodus sargus) Released on Artificial Reefs Off the Algarve (Southern Portugal)

    Lino, P. G.; Bentes, L.; Abecasis, D.; dos Santos, M. N.; Erzini, Karim
    Three hatchery produced and reared (HPR) and five wild white sea bream (Diplodus sargus) were double tagged with Vemco V8SC-2L acoustic transmitters and Floy Tag T-bar anchor tags, and released on artificial reefs located near a natural reef off the southern coast of Portugal. Passive telemetry was used to monitor movements of the white sea bream over a nine week period from April to June 2007. Differences in behavior at release, habitat association (artificial vs. natural reef), and in daily movements were registered. Wild fish moved from one habitat to the other with increased preference for the artificial habitat during...

  2. Distribution of vasoactive intestinal peptide in the brain and hypothalamo-hypophysial system of the sea bream (Sparus aurata)

    Power, Deborah; Ingleton, P. M.
    Vasoactive intestinal polypeptide (VIP) belongs to a family of peptides that show sequence conservation and include glucagon, secretin, glucose-dependent insulin-releasing peptide, growth hormone-releasing factor, peptide having N-terminal histidine and C-terminal isoleucine (PHI) and the reptilian peptides helodermin and the helospectins (TABLE 1). VIP and related peptides have been isolated from several species of teleost and they show a degree of sequence conservation similar to that found within mammalian peptides.
