A Simulation Study of Fishway
The paper argues that modelling provides a convenient and cost eeective means of characterizing and predicting the behaviour of environmental systems disturbed by man. A series of modelling criteria are suggested that aim at compelling modelling to work with current data, explicitly represent the current understanding of a system, include considerations of variability and address predictive unc...
متن کاملPerformance of Very Small Robotic Fish Equipped with CMOS Camera
Underwater robots are often used to investigate marine animals. Ideally, such robots should be in the shape of fish so that they can easily go unnoticed by aquatic animals. In addition, lacking a screw propeller, a robotic fish would be less likely to become entangled in algae and other plants. However, although such robots have been developed, their swimming speed is significantly lower than t...

15 صفحه اولAn Efficiency Analysis of a Nature-Like Fishway for Freshwater Fish Ascending a Large Korean River
Using traps and passive integrated transponder (PIT) telemetry, we investigated the effectiveness of the nature-like fishway installed at Sangju Weir on the Nakdong River, Korea. In 11 regular checks over the study period, 1474 individuals classified into 19 species belonging to 5 families were collected by the traps, representing 66% of the species inhabiting the main channel of the Nakdong Ri...
