Good correlations exist between condition and the amount of fat, protein and water present in young Tilapia rendalli , but extreme care must be exercised when determining the nature of these relationships. The use of percentages when expressing the amounts of each component should be avoided because such analyses can lead to erroneous results. Similarly the often used fat‐water relationship for predicting the fat content in fish should not be used as this also leads to erroneous results. The reasons for the poor relationships are discussed and methods for overcoming these problems are given.
