Insights into Daily Dynamics of Fish Migration during Spring in the Konda River
Hydrology and temperature are known as key drivers for fish migration in floodplain-channel systems of large rivers. The Lower Irtysh contains valuable species of whitefish and sturgeon.

Reservoir Operating Rules to Create Effective Fish Migration Passages in a Reservoir
Low flow velocity disrupts the potential fish migration passages in a reservoir, and causes reservoirs to become labyrinths for migratory fish. Previous studies showed that fish migration passages in a reservoir can be restored by modifying reservoir ...

A Multidimensional Continuum Model of Fish Population Dynamics and Behaviour: Application to the Barents Sea Capelin (Mallotus Villosus) [PDF]
The theoretical basis for a fishery model continuous in physical, temporal, and biological dimensions is discussed. A concrete application, constructed as one component of a larger system of physical and biological dynamic models descriptive of the ...

Numerical simulation of flow in a fishway of Karkheh-Hamidieh diversion dam and environmental considerations to investigate possibility of fishway use in Mazandaran Province [PDF]
Pool and weir is a type of fishway that provides a route for fish to migrate to damupstream. The effective parameters for fish swimming include velocity, water depth andturbulence.

Migration in Birds and Fishes [PDF]
Our knowledge concerning the periodical movements in animals called migrations is chiefly based on observations on birds. By and by, however, a number of facts concerning migration in other animal groups have been assembled and it seems worth while to compare them with those known for birds. There is the more reason to do so here, because the victim of

Evaluation of cone fishways to facilitate passage of small-bodied fish
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.

Global Warming Prediction Model of Fish Migration Based on ArcGIS [PDF]
Rising global ocean temperatures will disrupt the livelihoods of people who depend on fishing for marine crops. Therefore, we propose fishery migration prediction models to solve the problem. We considered the effects of seawater temperature and salinity,

Study of key technologies for fishways in the plateaus of western China
Determining how to restore fish migration routes blocked by large dams is the subject of great debate. Fishways are effective engineering measures restoring fish migration routes.
