สรุป	Electrofishing is a bioelectrical sampling technique in which electric current is applied to water to stun fish temporarily, allowing their capture for identification, measurement, and return to the stream. Developed in the 1950s and refined continuously, electrofishing is the standard method for inventorying fish communities in streams and small rivers, providing unbiased population estimates and species composition data.	Acoustic telemetry is a remote tracking method in which small electronic transmitters attached to or implanted in animals emit unique acoustic signals detectable by underwater or terrestrial receiver networks, enabling real-time monitoring of animal movements, positions, and behavior over extended distances and times. Pioneered in fisheries research in the 1960s, acoustic telemetry is now standard for studying movement ecology, migration timing, and habitat use in aquatic and increasingly terrestrial systems.	Focal Animal Sampling (FAS) is a systematic observational method in which an observer focuses on one individual animal at a time, recording its behavior continuously or at regular intervals for a fixed period. Introduced by Jeanne Altmann in 1974, FAS provides detailed, quantitative ethograms of individual behavior, making it essential for studying animal behavioral ecology, welfare, and responses to environmental changes.	Microhabitat Preference Analysis is a quantitative ecological method used to determine which fine-scale environmental features — such as vegetation structure, substrate type, temperature, or cover — animals actively select beyond what is randomly available to them. Widely applied in veterinary science, wildlife biology, and ethology, it compares the characteristics of locations an animal uses against those of randomly sampled available locations to infer habitat preference, avoidance, or random use.
