Are most fish species easily able to tolerate a large range of salinties?

Most fish species are not able to tolerate a large range of salinities; they typically have specific salinity preferences. However, some species, known as euryhaline fish, can adapt to varying salinity levels, such as those found in estuaries. In contrast, stenohaline fish are adapted to live in a narrow salinity range and cannot survive significant changes. Overall, the ability to tolerate salinity varies widely among fish species.
