תקציר	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.	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.
