Abstract The microbial load in ice-melt drainage collected from fishholds of fishing vessels stowing lizard fish, black croakers, cuttle fish, or nemipterids was very high, ranging from 2.1 x 10 to 2.2 x 10/ml for bacteria and 6.3 x 10 to 7.2 x 10/ml for yeasts and molds. Analysis of 100 colonies each randomly isolated from drainage samples of cuttle fish and lizard fish showed that the occurrence of bacterial genera as a percentage of the total was Moraxella-Acinetobacter, 61 to 62\%; Pseudomonas, 19 to 21\%; Alcaligens, 5 to 10\%; Flavobacterium, 1 to 4\%; Micrococcus, 1 to 4\%; Bacillus, Vibrio 0 to 2\%; Corynebacterium, 1 to 2\%; and others, 1 to 2\%. The organisms demonstrated versatile hydrolytic activities to a wide range of biological substrates including casein, gelatin, starch, DNA, and RNA. The possible connection between these bacteria and the deterioration of fish quality are discussed.
