摘要: Zero-ascend omnispecies (ZAO) attraction system includes a fish passage attraction module that can be deployed in a fishway where water flows downstream. The fish passage attraction module includes a body having a first end and an opposite second end, first adaptor adjacent the first end and second adaptor adjacent the second end. The adaptors are configured to alter water flow fields downstream of the module so as to attract fish to an entrance thereof.
