Because the intertidal zone is a complex coastal area exposed to a wide variety of environmental factors, the goal of this study was to look at how temperature, salinity, and dissolved oxygen of the water that remains trapped in the tide pools during low tide influenced the taxonomic distinctness of intertidal fish communities. Low tide exposes rocky pools to the air for several hours during the day, and environmental factors such as temperature and salinity are very changeable. Because the fish communities that inhabit these tide pools are also subjected to environmental variability, it's crucial to examine their structure in relation to important environmental factors like temperature, salinity, and dissolved oxygen on tide pools during spring tides, when they're exposed to more air. From January to December 2015, visual census surveys were conducted monthly in the intertidal zone of El Faro during spring tides on full moon days, when environmental variables fluctuate significantly. The census surveys covered a total area of 156*5 m. (780m2). A total of 145 tide pools were sampled and categorised into three categories (small, medium, and big) based on their size and depths of 20 to 45 cm. Temperature, salinity, and dissolved oxygen levels change during the course of the year. The temperature difference between the open ocean and the tide pools was between 3.5 and 4.5 degrees Celsius. A total of 3,576 organisms were found, representing 22 species, 12 families, four orders, and one class. When comparing taxonomic distinctness and average taxonomic distinctness between months and tidal pools of various sizes, values were close to the mean and fell within the confidence intervals in the tunnel.
