Resumo: | Feeding experiments with European glass eels &lt;i&gt;Anguilla anguilla&lt;/i&gt; L. demonstrated a high degree of attractiveness for the natural diets Tubifix and cod roe. Previous experiments had indicated that incorporation of bovine spleen and/or blood into paste feeds significantly improved the growth rate and survival. To increase feed consumption, the effect of some basic components available from the current generation of chemo-attractants were evaluated. Using a modified Omission Test Procedure, we focused on monosodiumglutamate, betaine, the nucleotides IMP and GMP, and fractions of cattle blood. These components were incorporated into non-attractive casein-based test diets and administered following standardized procedures to intensively cultured fingerling populations. These dose-response experiments revealed the Na-glutamate, betaine and the nucleotides IMP and GMP elicit feeding behaviour when administered separately. Only erythrocytes and the cell content of bovine blood induce an intensified feeding response. The effect of haemoglobin or organically-bound iron as attractant for eel is presently under investigation.
