Is a 25 cm salmon enough to feed family of 4?

The amount of food required to feed a family of four depends on a variety of factors, such as the age and appetite of the individuals. As a general guideline, a 25 cm salmon may be enough to feed a family of four if it is served with side dishes such as rice, vegetables, and/or salad. However, if the family members have large appetites or if the salmon is being served as the main course without side dishes, then a larger salmon or additional protein sources may be necessary.
