Fishways are being provided more regularly than ever before and new designs are needed to provide passage for whole fish communities. Despite recent progress, fishways have frequently performed poorly, especially for small-bodied fish (i.e. 10–100 mm long), which can form large aggregations below stream barriers. This was the genesis for the development of the cone fishway design, a new style of technical fishway which consists of a series of pre-fabricated cone-shaped concrete baffles installed laterally within a concrete channel. The cone design arose from the need to install rock ramp fishways at remote sites where rock was unavailable and where maintenance would be infrequent. The objective of the present study was to evaluate the suitability of the new cone fishway design to provide passage for small-bodied diadromous species (i.e. |
