The increased incidence of food-borne diseases from shellfish contaminated with Vibrio species have brought forward renewed interest in irradiation of shellfish and other seafood. Results are very promising for clams and oysters without killing the molluscs [65]. The radiation decimal reduction dose (Dio) determined for Vibrio cholerae 01 biotype El Tor inoculated into various molluscs was 0.14 kGy [66]. Similar radiation sensitivity of this organism was found in inoculated fish fillets and shrimp tails [67]. The radiation dose to eliminate as high as 10 CFU/g Vibrio spp. in oysters was 1.2 kGy [68]. The radiation Dio value for V. cholerae 01 biotype El Tor in marine snails was 0.11 kGy [69].

Cells of Vibrio fischeri, from the light organ of the fish Monocentrus japonicus, emit light only in dense cultures where a chemical inducer identified as N-(2-oxocaproyl)homoserine lactone689690 accumulates. 

Anguibactin (470) is a unique siderophore (microbial iron-transport compound) isolated from iron-deficient cultures of a fish pathogenic bacterium, Vibrio anguillarum (378). The structure of 470 was determined by X-ray diffraction studies of its anhydro derivative. Another related compound copurified with 470 was identified as 2-(2, 3 -dihydroxyphenyl)-thiazoline-4-carboxyiic acid methyl ester (471) (379).

The attempt of intentional introduction of five fish species from the estuaries of the Japan Sea, the Amur River, and other rivers of Southeast Asia was not successful two sea bass species occur as isolated individuals and only the pond carps and amurs dwell in freshwater lagoons, rivers, and deltas of the Black Sea, but their populations are supported by artificial reproduction. Two fern species and strains of Vibrio cholerae were brought from the same regions. 

Luminescent bacteria are found in various ecological niches, but most species are present in the ocean where some live in symbiosis with fish. Light emission can be switched on and off and it is the present thesis that bacterial bioluminescence goes by a sensitized chemiluminescence mechanism luminescent bacteria are placed into two genera, Vibrio and... 

The Microtox test system utilizes a strain of naturally occurring luminescent bacteria - Vibrio fischeri. Exposure to a toxic substance causes a disruption of the respiratory process of the bacteria resulting in reduced light output. The effective concentration (EC50) is determined as the concentration of a toxicant that causes a 50% reduction in light output over a prescribed period of time (typically 5, 15, or 30 min). The test is fast, fairly simple to conduct, uses small sample sizes, and is relatively inexpensive. Results correlate well with those from other toxicity bioassays such as fish and Daphnia. The test is used... 

Anguibactin, a siderophore of the fish pathogen, Vibrio anguillarum, is a virulence factor. When anguibactin was fed to a siderophore-deficient avirulent mutant of V. anguillarum, the mutant successfully established itself in the host fish [112].
