Assessment of Bacteriological Safety of the Seawater and Ark shell (Scapharca subcrenata) in Yeoja Bay, Korea

Abstract

This study evaluated the sanitary state of seawater and shellfish in Yeoja bay from January 2014 to June 2016. The sampling stations for sanitary survey in Yeoja Bay was composed of 50 stations for seawater and 4 stations for ark shell and the samples have been collected monthly at a stated date. The total and fecal coliforms in seawater and Escherichia coli (E. coli) in shellfish were investigated as sanitary indicator bacteria, respectively. The geometric mean and the estimated 90th percentile ranges of total and fecal coliforms for seawater were <1.8-3.9, <1.8-2.6 and <1.8-29.7, <1.8-9.3 MPN/100 mL, respectively. The range of E. coli levels for ark shell were <20~330 MPN/100 g. The sanitary state in Yeoja bay was evaluated clean area according Korea criteria and conditionally approved area according US criteria and Class B area according EU criteria.

Genetic Distances for Intra- and Between-Group of Scapharca subcrenata from Yeosu of the Korea

“…This invertebrate (Scapharca subcrenata) is economically and ecologically very significant bivalves in the Korean peninsula. Even so, these types of invertebrates, those are known chief reproductively (Lee, 1998;Kim et al, 2008), ecologically (Kim et al, 2019), as well as bacteriologically (Shin et al, 2016) are not heritably and/or molecular-biologically studied like other crustaceans. There is a demand to apprehend the innate traits and structure of this invertebrate group with the aim of estimating surely the correctly heritable benefit.…”
