Mass mortality of hatchery-reared milkfish (Chanos chanos) and mangrove red snapper (Lutjanus argentimaculatus) caused by Amyloodinium ocellatum (Dinoflagellida)

open access: closedAquaculture, 2004
Outbreaks of heavy infestation by the parasitic dinoflagellate Amyloodinium ocellatum in hatchery-reared milkfish (Chanos chanos) and mangrove red snapper (Lutjanus argentimaculatus) caused 100% mortality events in hatcheries in the Philippines. Parasites were recorded on the body surface in 14-day-old milkfish fry and on both skin and gills in 2-month-

Motion of the Longitudinal Flagellum in Ceratium tripos (Dinoflagellida): A Retractile Flagellar Motion1

open access: closedThe Journal of Protozoology, 1981
ABSTRACTThe longitudinal flagellum of Ceratium tripos moves in two dissimilar ways: undulation and retraction. The undulatory wave is planar and has a wavelength of 74.3 ± 9.6 μm and an amplitude of 14.2 ± 2.3 μm in sea water. The beat frequency is 30 Hz at 20°C, pH 8.0.

Chemical control of Amyloodinium ocellatum (Brown 1931) (Dinoflagellida) infections: In vitro tests and treatment trials with infected fishes

open access: closedAquaculture, 1984
Abstract In vitro incubation of dividing tomonts of Amyloodinium ocellatum (Brown 1931) was used to evaluate efficacy and mode of action of potentially paraciticidal chemicals. Copper sulfate, in concentrations up to 10 ppm, did not interrupt division. However, concentrations as low as 0.5 ppm were lethal to sporulating tomonts and dinospores.

Ionic Control of the Longitudinal Flagellum in Ceratium tripos (Dinoflagellida)1

open access: closedThe Journal of Protozoology, 1985
ABSTRACTIn order to answer the question of how two dissimilar flagellar motions, retraction and undulation, of the longitudinal flagellum in Ceratium tripos are regulated, the effects of cationic milieu, calcium ionophore, calcium channel blockers and some anesthetics on the motion of the longitudinal flagellum were studied. The flagellum retracted and

Amyloodinium ocellatum (Brown, 1931) (Dinoflagellida) infestations in cultured marine fish at Eilat, Red Sea: epizootiology and pathology

open access: closedJournal of Fish Diseases, 1980
Abstract. Since 1977, repeated outbreaks of infestation by Amyloodinium ocellatum (Dinoflagellida) in cultured gilthead bream Sparus aurata L. and seabass Dicen‐trarchus labrax (L.) resulted in sporadic and mass mortalities. Fingerlings and yearlings as well as breeders were affected and, since 1978, larval and post‐larval S.

The Ultrastructure of the Freshwater, Colorless Dinoflagellate Peridiniopsis berolinense (Lemm.) Bourrelly (Mastigophora, Dinoflagellida)1,2

open access: closedThe Journal of Protozoology, 1984
ABSTRACTThe ultrastructure of the freshwater, heterotrophic dinoflagellate Peridiniopsis berolinense (Lemm.) Bourrelly resembles other dinoflagellates in the structure of its nucleus, theca, flagella, and mitochondria. Other features less frequently reported in related organisms include fine sub‐sulcal fibers, collared pits in the flagellar base region,
