Feeding ecology and life-history strategy of nesting males in a fish with long ...
M. Félix, Pedro; Amorim, M.C.P.; Pereira, Tadeu; Fonseca, P.J.; Sousa-Santos, C.; Costa, José LinoThe Lusitanian toadfish, Halobatrachus didactylus, like other batrachoidids, is a benthic fish species with nesting behaviour during the breeding season. During this prolonged period it engages in mating activities and remains in the nest providing parental care. It is not known whether males feed while providing parental care but it is likely that their limited mobility may restrict their diet and influence th...
Movements of Diplodus sargus (Sparidae) within a Portuguese coastal Marine Prot...
Belo, Ana Filipa; Pereira, Tadeu; Quintella, Bernardo; Castro, Nuno; Costa, José Lino; Almeida, Pedro Raposo deMark-recapture tagging and acoustic telemetry were used to study the movements of Diplodus sargus within the Pessegueiro Island no-take Marine Protected Area (MPA), (Portugal) and assess its size adequacy for this species' protection against fishing activities. Therefore, 894 Diplodus sargus were captured and marked with conventional plastic t-bar tags. At the same time, 19 D. sargus were tagged with acoustic t...

Testing a 3-axis accelerometer acoustic transmitter (AccelTag) on the Lusitania...
Almeida, Pedro R.; Pereira, Tadeu; Quintella, Bernardo; Gronningsaeter, Aage; Costa, Maria José; Costa, José LinoA consortium composed of Thelma Biotel and Center of Oceanography developed and tested an acoustic 3-axis accelerometer transmitter. The first testing phase took place in experimental tanks and consisted of externally attaching prototype data logging tags in Lusitanian toadfish (Halobatrachus didactylus Bloch & Schneider, 1801) and comparing raw logged data with observed behaviours to obtain characteristic acce...
