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.

摘要： A fish ladder includes a channel with first and second sidewalls spaced apart at a channel width distance. Each of a first plurality of side-baffles is attached to the first sidewall and each of a second plurality of side-baffles is attached to the second sidewall. Each side-baffle extends a predetermined distance into the channel. A first slot opening width distance from a tip of each one of the first plurality of side-baffles across the channel and perpendicular to the second sidewall substantially equals a second slot opening width distance from a tip of each one of the second plurality of side-baffles across the channel and perpendicular to the first sidewall. A side-baffle spacing distance from a tip of each one of the first plurality of side-baffles and perpendicular to a corresponding one of the second plurality of side-baffles located upstream substantially equals the first and second slot opening width distances.

摘要： A migratory fish passage arrangement arranges water flow past an obstacle upstream of the water's natural flow direction, and includes a hydraulic flow arrangement with a first intake tube from upstream of the dam from an intake point to a location downstream of the dam to a feeding point, where a fish gate allows fish to enter into an elevation tube, to enter from the feeding point in the water in the elevation tube to be transported in the elevation tube to an outlet upstream of the dam. The intake point is higher than the outlet. Also disclosed is a system to guide a migratory fish to pass a dam that includes the migratory fish passage arrangement and additionally a siphon tube from an upstream location with respect to the dam to a downstream location with respect to the dam to constitute a migratory fish return route.

摘要： A method is provided for the artificial erosion of dammed bodies of water, wherein an average grain size distribution of sediments in the dammed body of water is determined across the ground surface of the dammed body of water. A sediment requirement for downstream water is determined, and as a result, at least one displacement of the sediments in the dammed body of water into the downstream water takes place in accordance with the sediment requirements for the downstream water. Advantageously, requirements regarding at least the quantity and grain size of the sediment for the downstream water are determined.

摘要： A mechanical fish trap system is adapted to be installed in native water environments. The trap chamber is positioned in a first native water environment. The chamber includes a trap gate to allow a fish to swim into the trap chamber and then retain it therein. A water pipe is connected to the trap chamber. A water pump then pumps water through the water pipe and into the trap chamber and out the trap gate. The water pipe inlet is positioned in a second native water environment that is imbalanced with the water in the first native water environment.

摘要： Transporter and fish lock including an upper inlet and an upper outlet adapted to be in flow communication with an upper volume of water, and a lower outlet and a lower inlet adapted to be in flow communication with a lower volume of water. The upper inlet and the lower outlet communicate via a downstream passage having a first effective through-flow area, and the lower inlet and the upper outlet communicate via an upstream passage having a second effective through-flow area. The downstream passage includes a first helical rotor having a thread-direction that by a flow directed downstream causes the first rotor to rotate around its axis. The upstream passage includes a second helical rotor, wherein the rotors are mutually connected such that the first rotor drives the second rotor in rotation around its axis, and the second rotor has a thread-direction that upon rotation generates a flow directed upstream.

摘要： An improved sensor fish with robust design and enhanced measurement capabilities. This sensor fish contains sensors for acceleration, rotation, magnetic field intensity, pressure, and temperature. A low-power microcontroller collects data from the sensors and stores up to 5 minutes of data on a non-volatile flash memory. A rechargeable battery supplies power to the sensor fish. A recovery system helps locating sensor fish. The package, when ready for use is nearly neutrally buoyant and thus mimics the behavior of an actual fish.
