Notes:
The precise feeding of fish entails a mineral supply tailored to meet requirements. The aim is an optimal supply status, that manifests itself in excellent health and productivity, combined with minimal water pollution. Having considered possible methods for determining requirements (i.e. factorial deduction or balance studies amongst others), the dose-response technique appears to be the best option. Sensitive indicators that measure utilization should be given priority, even when they have to be developed, and it is important to include as parameters biochemical criteria as well as retention of the elements in organs or the whole body. Here, however, the extent of the knowledge on homeostatic regulation of minerals will have to be extended. Work on availability of minerals should be carried out, in the suboptimal part of the supply range, under identical conditions. In estimating requirements, many factors (productivity level, chemical form of the compound, diet composition, interactions with other minerals and with waterborne elements) have all to be considered. Connections between these factors are presented in this paper, with examples given.
