Abstract:
A continuous-flow chamber is a simple experimental device initially used to study prey preferences of fish larvae. It consists of an aquarium and beakers as experimental units in which fish larvae/fry are kept. A pump provides a continuous flow of gravel-filtered water to the beakers. The chamber can accommodate 10 or more beakers. Treatments and their replicates can be assigned randomly to the beakers for an appropriate statistical test. A study was carried out to assess its applicability for studies on growth responses of fish larvae/fry and colour preference of artificial diets. The results showed that percentage survival was high (94-100%) in all experiments. Significant differences in growth responses for fish fry fed on live and artificial feeds were obtained. Tilapia fry showed no preference in terms of diet colour. This continuous-flow chamber is suitable and efficient for studies of fish fry growth responses.
