A Comparative Evaluation of Carcass Quality, Nutritional Value, and Consumer Preference of Oreochromis niloticus from Two Impoundments with Different Pollution Levels in Zimbabwe

Abstract: The objective of the study was to determine the quality and consumer preferences of Nile tilapia (Oreochromis niloticus) from two water bodies with different pollution levels and trophic states. Water quality assessment of the two impoundments was carried out. Fish were sampled from hypereutrophic Lake Chivero and oligomesotrophic Lake Kariba for proximate analysis, carcass quality, and sensory evaluation. Conductivity, dissolved oxygen, transparency, ammonia, total phosphates, reactive phosphates, and chlorop… Show more

“…Oreochromis niloticus is the most common fish species in Zimbabwe, constituting the dominant tilapia caught by artisanal and commercial fishermen. It is also produced intensively under aquaculture (Hamandishe et al, 2018). Decisions on the management of O. niloticus, therefore, should be based on the trade-offs between socio-economic benefits and potential adverse ecological effects (Zengeya et al, 2017).…”

“…27 For colorimetry, luminosity (L) values were evaluated using a colorimeter (MINOLTA CR-10, Minolta Camera CO, Osaka, Japan), where L* defines luminosity (L*=0 black and L*=100 white), a* (redgreen component) and b* (yellow-blue component) by CIELAB color system. 28 Microbiological analyzes were performed for the most probable number (MPN) of coliforms at 35°C and 40°C, counts of Staphylococcus coagulase positive in CFU g -1 and of Salmonella spp., according to APHA. 29 The microbiological protocol followed the standards established by Resolution RDC No.…”
