Characterization of Microorganisms in Fish and Farmed Water from Sidi M’Hamed Ben Tiba Dam (Algeria)

Abstract

Background: The production of fishery resources and the abundance of new species in our markets are becoming increasingly important. The consumption of fish continues to increase. Microbiological analysis of fish provides information on the diversity of the bacterial population abundant in these species. Methods: Our work was based on the isolation and identification of the bacterial flora of two fish species bred in extensive mode at the Sidi M’Hamed Ben Taiba dam (Barbel and Bighead carp). By introducing the influence environmental factors on the load and diversity of bacterial species by physicochemical (temperature, pH, turbidity, conductivity and dissolved oxygen) and bacteriological (search for total and faecal coliforms, enterococci and sulphate-reducing bacteria) analysis of the rearing water. Result: A variety of bacteria were isolated from the different compartments of the two fish species. Of which we were able to identify 12 species divided into 9 genera: Staphylococcus, Streptococcus, Pseudomomas, Serratia, Salmonella, Citrobacter, Proteus, Chrysobacterium, Stenotrophomonas and genera of lactic acid bacteria.
