Project

Marine migration of anadromous brown trout (Salmo trutta) mapped using acoustic telemetry

Publisher

Supervisor

Location

Greater Copenhagen area

Aim:

The aim of this study is to map the migration and temperature exposure of adult brown trout in the marine environment. Data will reveal if brown trout are vulnerable to climate change in the marine environment. Data will also reveal when brown trout are using a marine protected area.

 

Background:

In many rivers, brown trout exhibit an anadromous strategy where fish emigrate from the river to forage on abundant prey in the marine environment. While river migrations have been investigated frequently, the marine migrations remain poorly understood. For example, habitat use and temperature exposure have rarely been described in the marine environment. Knowledge in this field is important to manage and protect populations of anadromous brown trout. This is particularly important in areas where brown trout populations are supported by the release of juvenile fish raised in captivity. Climate change could expose brown trout to suboptimal or lethal temperatures, but it has not been examined.

 

Content:

This study will use fish telemetry to investigate the migration of adult brown trout in a large estuary (Roskilde Fjord), 40 km west of Copenhagen in Denmark. Fish captured in the wild will be tagged with tiny acoustic transmitters and tracked using stationary hydrophones and manual tracking from a boat. A film showing brown trout tagging is available here. Acoustic transmitters will not only reveal the position of the tagged fish in the estuary, the transmitters will also measure and transmit the temperature inside the fish. Temperature measurements can be used to estimate maximum growth rates and exposures to critical temperatures (e.g. during the summer). Stationary hydrophones will be positioned in narrow parts of the estuary and will be used to determine if the tagged brown trout emigrate from the estuary and enter the Kattegat Sea further north. The stationary hydrophones will also reveal if the tagged fish are utilizing a marine protected area situated in the southern parts of the Roskilde Fjord.


Duration:

Data collection for this project is expected to run for 2-6 months, followed by data analyses lasting 1-3 months and 1-3 months for write up. The project is large enough to accommodate 2-3 students.
