anadromy

Special attention is paid to changes in runoff, water levels, and river - and lake-ice regimes; to biogeochemical processes, including carbon dynamics; to rivers, lakes, ponds, and wetlands; to aquatic biodiversity and adaptive capacities; to fish populations, fish habitat, anadromy, and fisheries resources; and to aquatic mammals and waterfowl.

Freshwater ecosystems and fisheries in the Arctic 2009

Given that anadromy and feeding at sea results in greater size at a given age and larger populations [10], a switch away from anadromy is likely to result in decreased productivity.

However, the increased estuarine production discussed previously will possibly offset any tendency to reduce facultative anadromy in response to increased freshwater production.

Another ecological feature of arctic rivers, and one that is likely to be significantly affected by climate change, is that of anadromy or sea-run life histories of many of the fish species present (section 8.5).

Shifts in balance of anadromy versus non-anadromy decreases yields overall (i.e., smaller fish and perhaps more fish)

Impacts on arctic freshwater and anadromous fisheries 2009

Facultative anadromous species exhibit anadromy in polar regions to take advantage of marine coastal productivity and escape extreme oligotrophic conditions that typify arctic lake systems.

The most well-known example of anadromy is seen among the salmon.

Anadromous behavior 2008

As far as is known, anadromy commonly occurs only in the subspecies erythrinus in North America.

Where the species occur together, the Arctic char have life histories and habitat preferences, such as anadromy, that reduce direct contact with lake trout.

Some authors have incorporated behavioral characteristics such as spawning, anadromy, nest guarding, and territoriality.
