A ruthless fish killer: Treating and diagnosing Amyloodinium.

AMYLOODINIUM OCELLATUM BASICS: Oodinium has been a fast moving killer in marine fish keeping for many years in the aquarium hobby. Oodinium is a parasitic dinoflagellate which can infect and kill many species of saltwater fish.

Amyloodinium ocellatum (abbr. A.ocellatum) is a marine dinoflagellate. While most marine dinoflagellates (small protozoan organisms) exist as free living members of the planktonic community, some such as A. ocellatum live at least a portion of their life cycle as parasitic organisms.

Amyloodinium ocellatum is a parasitic dinoflagellate that infects warm water marine bony fishes and causes high mortalities in aquaculture settings. It has three life history stages: the feeding trophont, the reproductive tomont, and the infective dinospore. This dissertation describes the characteristics of A. ocellatum infections in juvenile spotted seatrout, Cynoscion nebulosus, and red.

A standardized method of propagating the marine fish parasite, Amyloodinium ocellatum. Bower CE, Turner DT, Biever RC. The peridinian dinoflagellate Amyloodinium ocellatum was propagated by serial passage in clownfish (Amphiprion ocellaris) and hybrid striped bass (Morone chrysops X Morone saxatilis). Each 25-50-mm fish was exposed to 4,000.

Persistent fish infestation by A. ocellatum was found at a highly saline lake in California. The seasonal dynamics of the infestation of young tilapia (Oreochromis mossambicus) was traced in 1997-98. First appearing in May, it became maximum in June-August, decreased in October and was not detectable in November. Outbreak of the infestation and subsequent mortality of young fish was registered.

History of Taxonomy. Standing in line at the grocery store, we get the opportunity to see what latest boy band member is dating (insert new TV star's name here). While deciding between brands of gum, you take a moment to decide if you ship the couple or not. Do they belong together? Probably not. It's probably best to just think about the gum.

Disclaimer: The Animal Diversity Web is an educational resource written largely by and for college students.ADW doesn't cover all species in the world, nor does it include all the latest scientific information about organisms we describe. Though we edit our accounts for accuracy, we cannot guarantee all information in those accounts.

Step 2a - It's a species. Okay, great. Species are easy to write about, even if almost every biologist has a different opinion on what a species actually is, and even if species from one part of the Tree of Life act totally different than species from another part.

Taxonomy, in a broad sense the science of classification, but more strictly the classification of living and extinct organisms. The internationally accepted taxonomic nomenclature is the Linnaean system created by Swedish naturalist Carolus Linnaeus, who drew up rules for assigning names to plants and animals.

Taxonomy (which literally means “arrangement law”) is the science of classifying organisms to construct internationally shared classification systems with each organism placed into more and more inclusive groupings. Think about how a grocery store is organized. One large space is divided into departments, such as produce, dairy, and meats. Then each department further divides into aisles.
