A bloom of Dinophysis acuta in a thin layer off North-West Portugal
Item type: Journal Article • Journal: African Journal of Marine Science • Authors: MT Moita L Sobrinho-Gonçalves PB Oliveira S Palma M FalcãoDinophysis acuta, which is responsible for diarrhetic shellfish poisoning, reached particularly high concentrations on the north-west coast of Portugal in 2003. In the Ría de Aveiro (40°41'N), the species reached a maximum concentration of 5.0 × 104 cells l−1 on... -
Are different species of Dinophysis selected by climatological conditions?
Item type: Journal Article • Journal: African Journal of Marine Science • Authors: L Escalera B Reguera Y Pazos A Moroño JM CabanasDinophysis acuminata and D. acuta, the main agents of diarrhetic shellfish poisoning outbreaks in the Galician Rías Baixas, North-West Spain, appear segregated in time and/or space and exhibit considerable interannual variability. To explore the specific requirements of the two species... -
Life-cycle stages of Dinophysis acuminata (Dinophyceae) in the Baltic Sea
Item type: Journal Article • Journal: African Journal of Marine Science • Authors: S Hajdu U LarssonDespite many observations of different life-cycle stages of Dinophysis species, the complete life history of the genus is still unknown owing to the difficulties encountered in culturing these species. The seasonal distribution of D. acuminata was followed at two offshore... -
Analytical detection of parasite infection of Dinophysis norvegica using FISH probes
Item type: Journal Article • Journal: African Journal of Marine Science • Authors: PS Salomon S Janson L-Å Gisselson E GranéliParasites of the genus Amoebophrya infect several free-living dinoflagellates, including harmful species. Whereas advanced infection can be easily detected, earlier stages of infection are more difficult to establish. rRNA-based fluorescent in situ hybridisation (FISH) probes specific to Amoebophrya sp. infecting... -
Accumulation of diarrhetic shellfish poisoning toxins in the oyster Crassostrea gigas and the mussel Choromytilus meridionalis in the southern Benguela ecosystem
Item type: Journal Article • Journal: African Journal of Marine Science • Authors: GC Pitcher --- Branch: Fisheries Management, Department of Agriculture, South Africa B Krock --- , Germany AD Cembella --- , GermanyDiarrhetic shellfish poisoning (DSP) poses a significant threat to the safe consumption of shellfish in the southern Benguela ecosystem. The accumulation of DSP toxins was investigated in two cultivated bivalve species, the Pacific oyster Crassostrea gigas and the mussel Choromytilus...
