Hydrological conditions of functioning of Ust-Manych fish channels
Ust-Manych fi shing channels are characterized by low efficiency of their work, which inflicts damage on the regional fishery. The analysis of the channel design enabled to establish a number of errors and shortcomings of their layout and design ...

Drifting with Flow versus Self-Migrating—How Do Young Anadromous Fish Move to the Sea?
Summary: The downriver migration process of young anadromous fish has a far-reaching impact on their survival rate and the efficacy of hatchery-reared fish release, but it is poorly understood.

Unravelling the life history of Amazonian fishes through otolith microchemistry [PDF]
Amazonian fishes employ diverse migratory strategies, but the details of these behaviours remain poorly studied despite numerous environmental threats and heavy commercial exploitation of many species.

A Mixed Optimal Control Approach for Upstream Fish Migration
This paper proposes a simple mathematical model forupstream fish migration along rivers. The model describes the fish migration along a river based on a mixed optimal control approach having swimming velocity, school size, and stopping time of migration ...
