Abstract
Microbiological changes of Indian prawn, Metapenaeus dobsoni frozen as whole (W) headless-shellon (HL) and peeled and deveined (PD) were investigated. Exposure to freezing temperatures caused mortality of major bacteria present in prawn, 83.67%, 79.48% and 52.90% of cells being destroyed in W, HL and PD types. Frozen storage for a period one month caused less destruction (13.58%, 16.90% and 9.78%). After two months, death was very slow and gradual. The results point to a difference in the survival rate of bacteria present on PD prawn. Qualitatively various genera were affected differently by freezing and frozen storage. Vibrio spp. were the most sensitive and Micrococcus spp. the most resistant.
