Fish Flatfish

Sand Sole

Righteye Flounders: Family Pleuronectidae

Species: Psettichthys melanostictus (Girard, 1854); from the Greek words psetta (flounder), ichthys (fish), melas (black) and stictos (specks).

Alternate Names: Halibut, sand flounder, spotted flounder, fringe sole or fringe flounder.

Identification: Sand sole are in the right-eye flounder family. Most easily identified by the fact that the first four to five dorsal rays are long and free (seemingly disconnected). Their coloring is generally gray to tan above with light speckling.

SizeTo 25 inches although 20-21 inches was felt to be maximum size until recently. Most caught from piers are under 16 inches in length. The largest I’ve caught were a nice 19 ¾-inch fish taken one early September morning at the Pacifica Pier and a 17 ¾-inch fish at the San Francisco Municipal Pier on another September morning.

RangeLa Jolla (near San Diego) to the southeastern Bering Sea and the Aleutian Islands (from Unalaska Island) to Port Heiden and Gulf of Alaska. The southern range has changed considerably over the years. Marine Fishes of Southern Californiaby Percy, Spencer and Barnhart (1936) does not list the fish among SoCal fish. The California Department of Fish and Game Fish Bulletin No. 68 by Roedel (1948) simply says Southern California but uncommon south of Point Conception. Fish Bulletin No. 157 by Miller and Lea (1972) list Port Hueneme as the southern limit the same as Coastal Fishes of the Pacific Northwest by Lamb and Edgell (1986). The Peterson Guide to Pacific Coast Fishes by Eschmeyer, Herald and Hammann (1983) lists Redondo Beach as the southern limit. Those ranges changed on February 3, 2005 when our PFIC Reporter, Snookie, caught a 15-inch-long sand sole at the Balboa Pier (which was followed by a report on the PFIC message board that night). The current range (to La Jolla) is given in Certainly More Than You Want To Know About The Fishes of The Pacific Coast by Milton Love (2011).

Habitat: Shallow-water areas, both sandy shore and rocky shore.

Piers: Primarily landed at piers from Monterey Bay north. Best bets: Seacliff State Beach Pier, Capitola Wharf, Santa Cruz Wharf, Pacifica Pier, Candlestick State Park Pier, Berkeley Pier, Point Pinole Pier, Fort Baker Pier, Del Norte Street Pier in Eureka and the “B” Street Pier in Crescent City.

Shoreline: An occasional catch in sandy shore areas in central California

Boats: Only occasionally taken from boats.

Bait and Tackle: Generally taken on cut bait such as anchovy, sardine or squid. Live grass shrimp and pile worms also make good bait. Most often landed on high/low leaders fished on the bottom but many are also taken in the Bay Area by fishermen using the live bait sliding rigging common for flounder. Hooks should be size 6 to 4.

Food Value: Excellent! Mild flavored flesh that is best fried or baked.

Comments: Sand sole are an excellent sportfish and are good eating. However, many of these sole are mistaken for California halibut and unnecessarily returned to the water because they do not meet the minimum size requirements for halibut. Learn to differentiate between the different flatfish species. Sandies live to about ten years of age.
