This verse from Genesis 11:23 means:
Serug lived two hundred years after he became the father of Nahor: This indicates that Serug was 130 years old when Nahor was born(Genesis 11:22). After Nahor's birth, Serug lived for an additional 200 years.
and became the father of more sons and daughters: After the birth of Nahor, Serug continued to have other children, both sons and daughters. The Bible doesn't name these other children, but it states they existed.
In essence, the verse conveys the longevity of Serug's life and that he had a family beyond just the son named in the genealogical line. It fits into the overall pattern of the genealogies in Genesis 11, which trace the descendants of Shem (one of Noah's sons) down to Abraham.
