The present study was conducted using geometric morphometric analysis of otolith to discriminate stocks of the predominant species of genus Acanthopagrus in the west and east of Strait of Hormuz. Samples were taken from 5 regions in the Persian Gulf and Oman Sea from March 2016 to March 2018. The 145-otolith samples were obtained from the Arabian yellowfin sea bream (Acanthopagrus arabicus). Th...

A procedure for long lasting general anaesthesia in gulls (LaTus sp.) is described. It is based on an initial basal intramuscular dose of pentobarbital sodium, supplemented if necessary by intravenous injection to effect of the same agent. Additional intramuscular pentobarbital is used to extend the duration of anaesthesia. The labile respiration of the birds is supported with oxygen. In cases ...

Salinities in some normally-closed estuaries in the central south coast of Western Australia are now frequently becoming highly elevated. This is due to: (1) high evaporation rates in water volumes that, by summer, are already low as a result of atypically dry winters; and (2) increased salt run-o¡ following vegetation clearing in the catchments. A few black bream (Acanthopagrus butcheri) died ...
