In my Ph D thesis I deal with an innovative implanted microsystem to estimate physiological parameters in fish. In a first time step conventional physiological single sensor will be tested to define parameters of different fish species (common carp, pike-perch and sturgeon) for the developing multi sensor. These long-term designed self-sufficient working system can measure temperature, swimming activity, resistance and potential of the skin as well as heart and breathing rate of monitored fish. In practice it can be used for veterinarian diagnostics in cases of an abiotic (temperature- und gas tension, pH-value -and nitrogen compounds, technology based stress) and biotic impact (fitness and nutrition, social interactions, parasitic diseases) on the health- and fitness status of fish populations.
Prospects:
- Health care diagnostic and –survey of fish in the aquaculture
- Behavioral ecology and ecological physiology in natural habitats
- Investigations of distinct behavior types in fish
- Relation between physiology/behavior and catchability of fish
