Shedding of Renibacterium salmoninarum by infected chinook salmon Oncorhynchus tschawytscha Shedding of Renibacterium salmoninarum by infected chinook salmon Oncorhynchus tschawytscha

Laboratory studies of the transmission and pathogenesis of Renibacterium salmoninarum may describe more accurately what is occurring in the natural environment if test fish are infected by waterborne R. salmoninarum shed from infected fish. To quantify bacterial shedding by chinook salmon Oncorhynchus tschawytscha at 13??C in freshwater, groups of fish were injected intraperitoneally...

Immunostimulants in fish diets Immunostimulants in fish diets

Various immunostimulants and their methods of application in fish culture are examined in this review. Important variables such as life stage and innate disease resistance of the fish; immunostimulant used, its structure and mode of action; and the fish's environment are discussed. Conflicting results have been published about the efficacy of immunostimulants in fish diets. Some...

Influence of externally attached trasmitters on the swimming performance of juvenile white sturgeon Influence of externally attached trasmitters on the swimming performance of juvenile white sturgeon

We measured the critical swimming speed of juvenile white sturgeons Acipenser transmontanus equipped with externally attached dummy ultrasonic transmitters and of untagged control fish in the laboratory. White sturgeons ranging from 31.9 to 37.0 cm fork length were subjected to one of three treatments: Control (handled but not tagged), tag attached below the dorsal fin, and tag attached...

Conversion of the pathogenic fungus Colletotrichum magna to a nonpathogenic, endophytic mutualist by gene disruption Conversion of the pathogenic fungus Colletotrichum magna to a nonpathogenic, endophytic mutualist by gene disruption

Hygromycin-resistant transformants of the cucurbit pathogen Colletotrichum magna (teleomorph: Glomerella magna) were generated by restriction enzyme-mediated integration (REMI) transformation. A rapid pathogenicity assay involving watermelon (Citrullus lanatus) seedlings was developed and 14,400 REMI transformants were screened and assessed for their ability to cause disease, colonize...

Some preliminary findings on the nutritional status of the Hawaiian spiny lobster (Panulirus marginatus) Some preliminary findings on the nutritional status of the Hawaiian spiny lobster (Panulirus marginatus)

Data on the nutritional status of spiny lobster (Panulirus marginatus) were collected on the commercial trapping grounds of Necker Bank, Northwestern Hawaiian Islands, in the summers of 1991, 1994, and 1995. Glycogen levels measured in abdominal tissue of intermolt males were used as an index of nutritional health of the field population. The range of glycogen sampled from wild lobster...
