Seasonal Effects on Physicochemical and Bacteriological Profiles of a Mangrove Ecosystem in Rivers State, Nigeria

During the dry and rainy seasons, seasonal effects of physicochemical and bacteriological profiles of the mangrove ecosystem have been established. To determine physicochemical and bacteriological parameters, standard analytical methods were used. Except for salinity, which had relatively higher values during the dry season, the findings showed higher values of physicochemical parameters in the rainy season than in the dry season. During the rainy season, the bacterial diversity was much greater than during the dry season. Spp. bacillus. During the two seasons, it was the most prevalent (32-39 percent), but in the dry season, Vibrio spp was the most dominant (31 percent). Pseudomonas, Staphylococcus aureus, Enterobacter aerogenes and Proteus species were other microbes isolated at a relatively high percentage in both seasons. Physicochemically, the field of study has shown great potential for aquatic life forms for growth , survival and sustainability. However, the isolation of pathogens of this magnitude posits A high risk to food safety and public health in the absence of purification of fish and other food safety steps prior to consumption.
