Biotelemetry and data logger system for measuring behavior and ecology of marine organisms

Abstract

The coexistence of marine mammals, seabirds, sea turtles and fish is an important factor for future fishery continuation. However, in the underwater, it is difficult to observe free-ranging behavior of marine organisms in spite of present-day technical progress. Research on the behavior, ecology, and physiology of marine organisms under natural conditions is limited, except for the information acquired from marine organisms by direct observation and direct measurement. Therefore, biotelemetry is useful technique to observe the habits of marine mammals needed for coexistence with the fisheries. The technology of biotelemetry is developed with use of the communication technology using the artificial satellite, the development of a micro-data logger that carried various sensors by ultra miniaturization of electronic products, etc. Thereby, according to the research purpose and the target marine organisms, we can choose the system of various kinds.
