Species profiles: life histories and environmental requirements of coastal fishes and invertebrates (Pacific Southwest) - California grunion. [Leuresthes tenuis]
The California grunion (Leuresthes tenuis) has little commerical importance but is one of the most popular sport fish along the beaches of southern California. Calfornia grunion spawn on sand beaches about every 2 weeks (as many as eight spawning per female) during full and new moon tide cycles. The spawning season begins in February-March and may extend to early September. The eggs hatch in about 2 weeks. California grunion mature at young age and have a life span of about 3 years. Larvae and adults prey on planktonic organisms, primarily copepods. Eggs are preyed upon by beach scavengers; adults are forage for larger piscivores. They host several crustacean and digenetic trematode parasites. 34 refs., 2 figs.
