Sand Bass Features
If you are fishing in Southern California water, knowing or at least familiarizing the sand bass fish features may help you identify them. This fish is slender with a pointy head. The small ones usually have brighter colors compared to the faded colors of the large sand bass fish.
The semblance of sand bass and kelp bass are close, but kelp is brown with white blotches in color. These fish species are easily singled out from related species because of their dorsal fin. It has a high, flag-like third spine.
They range from dark grey to greenish with dusky or faint bars on the side color. Sand bass has a white belly, and most have freckles on their snouts.
Additionally, there is one recorded albino sand bass that was 10 inches in length. Los Angeles County Museum of Natural History currently houses this albino sand bass.
Distribution and Diet
Sand bass are found on sand rock areas, ranging from the open water of central California’s Santa Cruz to southern Baja California’s Magdalena Bay. These fish species go as far north as Morro Bay and are common from Santa Barbara southwards.
They are rare in high relief, but they are the major species of artificial reefs. While most of these fish are common at 10-120 feet, the fledgling sand bass usually inhabits the shallow waters. The small fish usually swim at a depth of 5-30 feet during late summer to early winter.
The youngsters feast on small invertebrates like amphipods and mysids. In comparison, the mature fish’s diet consists of other fish like midshipmen, crabs, and octopi.
Spawning Season
During the non-spawning season, some barred sand bass usually likes to swim in isolation. Others are in the company of at least a few others. But when April comes, sand bass mass together for the spawning season.
They will often leave their usual rock and rubble haunts as they search for water with flat, sandy bottoms. The spawning season may start in April or May and peaks in July. It is the time when their eggs and larvae are drifting in the open seawater, as these species are pelagic spawners.
Sand bass does not change their position often. so after the spawning season, when the gaunt and listless fish return to their reefs, the sand bass show movements of up to 40 miles.
Fishery
Sport fishery is common in Southern California and northern Baja California, in which sand bass are a significant part. Reportedly, most catch of this fish was by using boat, but significantly large amounts were also from jetties, piers, and even calmer surf areas.
The summer spawning season is what the private and party vessels concentrate on. However, commercial fishing of sand bass species is illegal.
Size and Growth
Barred sand bass maturity usually takes five years, and they reach 10.5 inches in length. However, some only take two years to mature, and they’d be 7 inches long. This fish species can get up to 24 years, 25.5 inches in length, and can weigh a whopping 6kg on your fish scales.
Frequently Asked Question
Live squid may be the best bait for most of southern California’s game fish, including the sand bass.
Other options include small live mackerel and pieces of chunked or stripped dead mackerel. You may also use other fish species like anchovies and “brown baits” like queenfish or white croakers to get them out of the water. For other experienced fishers, artificial lures like plastic shrimp and grubs are also useful in fishing for barred sand bass fish species.
