Abstract
Qualitative and quantitative investigations were made on the luminous bacteria associated with the gut of pond cultured milk fishChanos chanos. Significant differences in luminous bacterial numbers were found between gut and pond water and between gut and pond sediment, but not between pond water and sediment. No significant variation in luminous bacterial population among the gut regions was observed. The quantity of ingesta in the fish gut does not appear to influence the biomass of luminous bacteria.Vibrio harveyi andV. fischeri were the 2 most commonly encountered species, and of the 2 luminous species,V. harveyi was predominant.
