Viviparous. Mating is preceded by courtship. The male moves slowly toward the female, who retreats. Her flight stimulates pursuit by up to 10 males. During the pursuit, males attempt to bring their anal regions in contact with that of the female. One male heads off the female, urging her away from the group of males and also driving them away. The female is conducted to the shelter of a rock or other object, where the courtship dance begins. In this dance, the male, with dorsal fin fully erect, swims by means of his pectoral fin in a figure eight pattern over the female, udulating in both the horizontal and vertical planes. The male then stops, faces the female head to head, quivers, then moves his jaws and undulates his dorsal fin. He then moves beside the female, facing in the same direction, and repeats the movements. Finally, the male tilts on his side, the female tilts slightly away from hin, and the anal regions are brought in contact with each other. Copulation lasts less than a second. Gestation takes five to six months. Bears 3 to 36 young. Female carries the developing young (Ref. 205). Males are mature and ripe at birth. Juvenile females are mated soon after being born (Ref. 27547).
The shiner perch (Cymatogaster aggregata) is a common surfperch found in estuaries, lagoons, and coastal streams along the Pacific coast from Alaska to Baja California. It is the sole member of its genus.
Shiner perches are similar to tule perches, deep-bodied with a dusky greenish back and silvery sides that have a pattern combining fine horizontal bars with three broad yellow vertical bars. Breeding males turn almost entirely black, the barred pattern being obscured by dark speckles. Shiner perches are distinguished from tule perches by having fewer dorsal fin spines, just 8–9 vs the 15–19 of the tule perch. The rayed part of the dorsal fin has 18 to 23 rays. The anal fin has 3 spines followed by 22–25 rays.
They are one of the most common fish in the bays and estuaries of their range, favoring beds of eelgrass, and often accumulating around piers as well. They feed on zooplankton such as copepods, but have been observed to bottom feed as well.
