Feeding trials under water

Besides kitchen waste we had underwater feeding experiments on our agenda, as on every JBL expedition. Due to the extreme currents, only sites in areas with slight currents, such as the anchorage within the lagoons, were feasible.

At a depth of just a few metres, the fish were offered various food mixtures (prototypes for the planned JBL marine food) and their reactions were recorded. A freshwater food was used as a comparison food and it was clear that many of the reef inhabitants were reacting with significantly less enthusiasm to this food. The ingredients of freshwater food are designed for freshwater fish and not for marine life.
