Notes:
Data on dietary preferences, filter-feeding mechanisms and ingestion rates of algae by tilapias are outlined and discussed. Quantitative data on algal ingestion by filter-feeding are incorporated into a bioenergetic model, demonstrating that under most conditions tilapias are unable to fulfil basic maintenance requirements and hence lose weight. It is concluded that the apparently high volumes of algae ingested by tilapias must be achieved by other means, by particulate feeding on aggregations of algae in the water column or flocculent surface scums of cyanobacteria or by grazing on periphytic mats.
