Advances In Invertebrates And Fish Telemetry: Proceedings Of The Second Conference On Fish Telemetry In Europe, Held In La Rochelle, France, 5-9 April 1997 (developments In Hydrobiology)

This volume provides a selection of the most significant papers presented at the Second Conference on Fish Telemetry in Europe in La Rochelle, France, in April 1997. The conference was attended by 100 scientists from 18 countries. The contributions are grouped under the following headings: Methodology and New Developments, Tagging Procedures, Behavioural and Physiological Ecology, Fish Migration, Stock Management and Conservation. Particular emphasis was put on tag miniaturisation, multiple functions and sampling strategies. Papers concerned the effects of tags on fish for consolidating behavioural or original physiological investigations noticeably more open to the marine environment. Methods were essentially applied to study the relationships between fish and their natural environment. Besides providing up-to-date information on the state of fish telemetry, the book illustrates the increase in spatial and temporal scales and the number of tracked fish which gives a statistical basis for field study in behavioural ecology.
