Fishes that swim upstream in rivers to spawn must navigate complex fluvial velocity fields to arrive at their ultimate locations. One hypothesis with substantial implications is that fish traverse pathways that minimize their energy expenditure during migration. Here we present the methodological and ...
on the other hand, cause harm indirectly. In the case of the paddlefish, they forage near the sea but swim upstream to spawn. Starting with Gezhouba Dam in the late 80s, barriers were erected across the migration route. They are

Most are confined either to saltwater or to freshwater, but some are physiologically adapted to moving from one to the other. A number of fishes that are born in freshwater spend their adult lives in the ocean, returning to their birthplace to spawn; the reverse of this migration occurs in ...
Spring and early summer present incredible shallow panfish opportunities, as these fish swarm to shorelines and nearby cover to spawn. Often, the bulk of the quality-sized panfish will methodically slide to the outside weedline and then suspend over nearby deep water as the heat of midsummer ...
