    Notes: General morphology of the lateral line of juvenile steelhead trout, Salmo gairdneri, is described. Through electrophysiological monitoring of individual nerve fibres, control patterns for spontaneous activity and reaction to sensory receptor stimulation were established. Spontaneous activity has a positive correlation with temperature and number of receptors innervated. Presence of directional sensitivity and response to near field water displacement at different frequencies is similar to that found in other fishes and amphibians. Normal lateral line response to a standardized set of stimuli was compared with the response of fish affected by gas-bubble disease. Results show that as gas emboli formed in the scale pockets of the trunk lateral line of stressed fish, the ability to respond to stimuli was either diminished or completely disappeared. Further testing demonstrated that this sensory loss was reversible and that upon return to equilibrated water gas emboli disappeared and normal function was regained. This sublethal effect of gas-bubble disease on the lateral line sensory system may be an important element contributing to indirect mortality.

    Vibrio ordalii sp. nov.: A causative agent of vibriosis in fish (1981)

    Notes: Abstract Vibrio ordalii sp. nov. is the name proposed for the bacterium previously designated asV. anguillarum biotype 2. The change in the classification of this fish pathogen is based on differences between the classicalV. anguillarum andV. ordalii in cultural and biochemical characteristics, and in deoxyribonucleic acid (DNA) sequence relatedness. Phenotypically,V. ordalii was distinguishable fromV. anguillarum based on: negative Voges-Proskauer reaction; negative reaction with arginine in Moeller's medium; negative Simmons' and Christensen's citrate test; negative ONPG test; failure to hydrolyze starch; failure to show lipase activity; inability to grow at 37°C; and failure to ferment cellobiose, glycerol, sorbitol, and trehalose. Genotypically, strain ofV. ordalii formed a highly conserved DNA homology group which showed 83 to 100% within-group homology and only 58 to 69% relatedness toV. anguillarum. In contrast, theV. anguillarum strains tested showed greater than 70% withingroup homology and 53 to 67% relatedness toV. ordalii. NeitherV. ordalii norV. anguillarum were related toV. parahaemolyticus orV. alginolyticus. The proposed type strain (holotype) ofV. ordalii is ATCC 33509 (=DF3K=Dom F3 kid).
