Abstract

Aeration rates and tank geometry result in different larvae survival rates [1]-[6]. This study reports new results about the flow field in a rearing tank. Specifically, the effects of the aspect ratio AR (the ratio of water depth to tank radius) on overall flow fields were clarified from flow visualization and PIV (Particle Image Velocimetry) experiments. Two different types of flow patterns, a single-pair vortex system and two-pair vortex system, were confirmed as the value of tank aspect ratio changed from 1.0 to 2.0.
