A biotic factor is a living factor. An abiotic factor is a nonliving factor such as salinity, oxygen levels, pollution, and so on. So biotic factors of a freshwater fish is gonna be food, predators, the amount of algae and plants or autotrophs in the stream, river, pond, creek, lake, or so on. Youneed to scroll down a little at this link but it discusses biotic factors there. Looks like symbiosis, mutualism, and commensialism and so on, or interspecific relations, are also biotic factors.
