Phytochemistry, 1974
Abstract A Florida red tide organism, Gymnodinium breve Davis, an unarmored dinoflagellate, was grown in enriched sea water media at salinities 20–43% and constant illumination. Use of lowest (23%) and highest (43%) salinities resulted in death within 24 hr of inoculation, though good growth was obtained at all intermediate salinities (29–39%), in ...

Effect of Illumination on Ichthyotoxin in an Axenic Culture of Prymnesium parvum Carter
The Journal of Protozoology, 1962SYNOPSIS. Cultures of Prymnesium parvum subjected to constant illumination failed to produce ichthyotoxin. On the other hand cultures subjected to alternate periods of light and darkness showed a gradually rising ichthyotoxic activity during the dark period reaching a maximum after about 7 hours.

A strain of Alexandrium leei Balech that was isolated in October 2002 from Singapore coastal waters and identified by light and scanning electron microscopy and phylogenetic analysis using LSU rDNA sequences, is toxic to Asian sea bass fingerlings (Lates calcarifer Bloch).

Toxicon, 1999
Curacin-A, antillatoxin and kalkitoxin, natural products from the marine cyanobacterium Lyngbya majuscula, were tested for neurotoxicity in primary cultures of rat cerebellar granule neurons. Curacin-A was non-toxic, whereas antillatoxin and kalkitoxin produced concentration-dependent cytotoxicity with LC50 values of 20.1+/-6.4 and 3.86+/-1.91 nM ...

The marine alga Chattonella marina is often associated with massive fish mortality worldwide. Here, we challenge brevetoxins and free fatty acids as the ichthyotoxins of C. marina by comparing the toxicity of C. marina with a brevetoxins-producing alga Karenia brevis as well as their organic solvent extracts using the seawater medaka Oryzias melastigma.

Blooms of ichthyotoxic microalgae are responsible for many fish kills worldwide. The haptophyte Prymnesium parvum and the dinoflagellate Karlodinium armiger are examples of toxic species producing allelochemical compounds, prymnesins and karmitoxin respectively. Prymnesins comprise a large group of analogs categorized into A-, B-, and C-types. The mode

Shark-Repelling Ichthyotoxins from the Defensive Secretion of the Sole Pardachirus pavoninus
1984Toxic fish are categorized into three groups by Halstead (Halstead 1978). The first group, termed poisonous fish, comprises those causing fish poisoning when eaten by humans, and is classified according to location of the toxin. Common fish poisoning, such as puffer poisoning and ciguatera, is caused by eating the flesh, and the fish responsible are ...

Within the last two decades, Prymnesium parvum (golden algae) has rapidly spread into inland waterways across the southern portion of North America and this organism has now appeared in more northerly distributed watersheds. In its wake, golden algae blooms have left an alarming trail of ecological devastation, namely massive fish kills, which are ...
