A review of mycobacteriosis in marine fish
Journal of Fish Diseases, 2009AbstractMycobacteriosis is a serious and often lethal disease of fish, affecting a wide range of species globally both in culture and wild settings. Caused by several species of the genus Mycobacterium, the disease has received considerable attention in recent years because of the discovery of new species in piscine hosts, epizootics in wild fisheries,

Comparative hematology in marine fish
Comparative Biochemistry and Physiology Part A: Physiology, 19921. A comparative study involving 80 species (14 ray, 14 shark and 52 teleost species) of marine fish found at the southeastern Brazilian coast is presented. 2. Active species displayed higher values for all hematological parameters studied when compared to the less active forms. 3.

Bacterial diseases of marine fish
Veterinary Record, 1989The principal bacterial diseases found among wild and cultured marine fish are reviewed. The bacterial agents discussed include the Gram-negative pathogens in the Vibrio, Aeromonas, Pasteurella and Edwardsiella genera, Renibacterium salmoninarum and the myxobacteria, streptococci, mycobacteria, nocardias and anaerobic organisms which have been ...

Extinction Risk in Endemic Marine Fishes
Conservation Biology, 2011[Extract] Developing effective management strategies for conserving species requires identifying the species with the greatest probability of extinction and determining why the probabilities are high. In terrestrial systems, endemic island species have the highest rates of extinctions (Frankham 1998; Whittaker 1998).

Dimethylnitrosamine in Chinese marine salt fish
Food and Cosmetics Toxicology, 1973Abstract Samples of marine salt fish from the markets in Hong Kong were analysed for N , N -dimethylnitrosamine (DMNA). Significant amounts of this compound, commonly in the 0·05-0·3 ppm range, were detected by gas chromatography and were confirmed in several samples by gas chromatography-mass spectrometry.

Collapse and recovery of marine fishes
Nature, 2000Overexploitation and subsequent collapse of marine fishes has focused attention on the ability of affected populations to recover to former abundance levels and on the degree to which their persistence is threatened by extinction. Although potential for recovery has been assessed indirectly, actual changes in population size following long-term ...

Microinjection of Marine Fish Eggs
2018Microinjection is a powerful tool for studying embryonic development and analyzing gene functions in fish. This technique was first applied to model species of fish such as zebrafish and medaka whose egg chorions could be removed or softened before microinjection.

The zoogeography of trematodes of marine fishes
Experimental Parasitology, 1955Examples are cited of the zoogeographical significance of the parasites of Lota lota, Aplodinotus grunniens, Coregonus, Cyprinidae, Anguilla spp., and Galaxias. Of 20 species of trematodes of Atlantic eels (Anguilla) 14 are shared with marine fishes, 5 with freshwater fishes, and only one species is limited to the eel. Pacific eels are known to have

Susceptibility of marine fish to trypanosomes
Canadian Journal of Zoology, 1977Trypanosomes, some of similar morphology and morphometry, were observed in the blood of seven species of marine teleosts (Pleuronectiformes: American plaice (Hippoglossoides platessoides), yellowtail flounder (Limanda ferruginea), and grey sole (Glyptocephalus cynoglossus); Perciformes: Arctic eelpout (Lycodes reticulatus), spotted wolffish ...

Nature, 1958
IN the course of a comparative investigation of the vitamin contents of different organs from fish1, a rather interesting relative distribution, and in some cases unusually high concentrations, of vitamin B12 were observed. As the importance of vitamin B12 in marine ecology has been emphasized in recent reports2–6, a brief account of the main findings ...
