The giant sea bass (Stereolepis gigas) is a fish native to the North Pacific Ocean. Despite its conspicuous size and curious nature, relatively little is known about its biology or behavior.
Giant sea bass reaching a size of 2.5 m (8.2 ft) and a weight of up to 255 kg (562 lbs) have been reported. However, in Charles F. Holder's book The Channel Islands of California, published in 1910, the author claims specimens taken from the Gulf of California attained 800 lb (360 kg). Aside from its tremendous size, the giant sea bass is also known for its lengthy lifespan. They mature around the age of 11 or 12, around the weight of 50 lb. However, some of the largest specimens have been known to exceed 7 ft, and are estimated to be 75 years or older.
In the eastern North Pacific, its range is from Humboldt Bay, California, to the Gulf of California, Mexico, most common from Point Conception southward. It usually stays in relatively shallow water, near kelp forests, drop-offs, or rocky bottoms and sand or mudflats.
Giant sea bass feed on crustaceans, as well as a wide variety of fish. For populations off the coast of California, anchovies and croaker are prominent food sources. Mackerel, sheephead, whitefish, sand bass, and several types of crab also make up the sea bass's diet. Despite their great size and bulky appearance, giant sea bass have been known to move extremely quickly, outstripping bonito.
Giant sea bass were once a relatively common inhabitant of Southern California waters, yet in the 1980s, it was facing the threat of local extinction off the California coast. Beginning in the late 19th century, the species supported both a commercial fishery taking hundreds of thousands of pounds annually, and a sport fishery that also landed hundreds of fish each year.
