who is the white croaker
The white croaker is a fish of the family Sciaenidae that lives on sandy bottoms of the eastern Pacific, from Canada to Baja California, Mexico, usually down to 30 m deep, though it reaches 183 m. It grows to 41 cm and can live 15 years. It feeds on polychaete worms, small shrimp, crabs and molluscs that it searches for on the bottom. It spawns several times, releasing pelagic eggs. It is taken in small-scale commercial fishing and also attracts sport anglers.

fun facts
- It spawns several times in the same season, releasing its eggs into the water.
- It can live up to 15 years.
identification
Elongated, fusiform body of pale colour. The most useful mark is the fleshy appendage at the base of the pelvic fins, and the first ray of those fins ends in a loose thread. On the California coast there are other croakers, such as the spotfin croaker (Roncador stearnsii) and the yellowfin croaker (Umbrina roncador), but this detail of the pelvic fins helps identify it.
