الملخص	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.	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.
