Abstract
The native flora of fresh oil sardine (Sardinella longiceps ) and mackerel (Rastrelliger kanagurta ) consisted mainly of Pseudomonas spp; Moraxella spp.; Acinetobacter spp. and Vibrio spp. During spoilage in ice, nearly 75% of their bacterial flora belonged to Pseudomonas spp. alone. But Na sub(2) EDTA treatment reduced the proportion of Pseudomonas) spp. considerably and the major bacterial groups at the time of spoilage were Moraxella spp. and Acinetobacter spp. In the case of fresh prawn (Metapenaeus dobsoni ) the native flora were constituted by Pseudomonas spp.; Moraxella spp.; Acenetobacter spp. and Vibrio spp. At the time of spoilage of prawn in ice, Moraxella spp. and Acinetobacter spp. predominated, together constituting 74% of the total population. Na sub(2) EDTA treatment did not alter significantly the spoilage flora of prawns. Morazella) spp. and Acinetobacter spp. accounted for 86% of the spoilage flora in ice storage of Na sub(2) EDTA treated prawns.
