Rock bass are sexually mature at about 2 to 3 years of age. Rock bass are polygynandrous, in which both females and males have multiple mates during the breeding season. Spawning occurs from April to early June in warm waters ranging 12–15 °C (54–59 °F), with females laying from 2,000 to 11,000 eggs. [7]
The breeding season extends from late spring to early summer (October to December). Eggs – up to 400 per female and breeding season – develop iteroparously, and spawning occurs after a batch of eggs has become fully developed; it is thus repeated several times during a breeding season until the entire batch of eggs has been laid.

In 2009, the European Union designated protection for spawning habitat on the edge of the Scottish continental shelf and at the edge of Rosemary bank for three months during the spawning season. [1] In Norwegian waters, blue ling are allowed as bycatch only (10%), which has had the same effect as closed areas regulation given avoidance of ...

Spawning occurs from June to mid-August in shallow waters. During the spawning season, the males go through a color change phase.
