Guitarfishes: Family Rhinobatidae
Species: Rhinobatos productus (Ayres, 1854); from the Latin word rhin (shark with a rough skin) and the Greek word batis (a ray or skate), and the Latin word product (a lengthened form, in reference to its long shape and form).
Alternate Names: Shovelnose shark, sand shark or guitarfish. Called guitarra viola in Mexico.

Identification: They have a rather spade-shaped head with a long and pointed nose; the disk is longer than it is wide. Their body is flattened but the tail is well developed with two dorsal fins on the top. Their coloring is sandy brown above, white below. (They also have the “most soulful, woebegone eyes you have ever seen.” This last reference is from the book Certainly More Than You Want To Know About The Fishes Of The Pacific Coast by the eminent marine biologist Dr. Robin Milton Love, a book that every angler who fishes California’s coast should read.)
Size: Reported to 5 1/2 feet in length and over 40 pounds. Typical size at piers is from two to four feet.

Range: Southern Mexico and the Gulf of California to San Francisco. Though once considered rare north of Monterey Bay, quite a few have been reported from San Francisco Bay piers since 2007.
Habitat: Found on sandy beaches in coastal waters as well as bays (on both muddy and sandy bottoms) to a depth of about 50 feet. Sometimes appears in very large aggregations (apparently when they’re in “the mood”). Typically feeds on worms, crabs, and clams.
Piers: One of the most common rays at all piers south of Pismo Beach and one of the favorites due to their size and the delicious meat which can be cut from the tail. Best bets: Imperial Beach Pier, Ocean Beach Pier, Crystal Pier, Oceanside Pier, San Clemente Pier, Newport Pier, Huntington Beach Pier, Seal Beach Pier, Hermosa Beach Pier, Santa Monica Pier, Ventura Pier and Goleta Pier.
Shovelnose taken at the Cayuos Pier
Shoreline: A favorite catch of southern California shore fishermen, especially in bays.
Boats: A few are caught by boaters and kayakers in San Diego Bay, Mission Bay, and San Pedro Bay.
Bait and Tackle: Since this is one of the larger fish most pier anglers will encounter, you should use at least medium saltwater tackle—twenty pound test line and size 2 to 4/0 hooks. Guitarfish will hit almost any bait but live anchovies, smelt, shinerperch and brown bait—small queenfish or white croaker—seem to work best. Other baits considered to be good include ghost shrimp, squid, clams, innkeeper worms and cut mackerel or anchovies. Bait should be fished as close to the bottom as possible and in shallow water, just past the breakers. Most commonly seen in summer and fall.

Food Value: Excellent. Unfortunately most anglers simply discard these rays even though, in taste and texture, the meat is very much like that of expensive scallops. However, more and more people are learning how to properly prepare Mr. Shovelnose.
Comments: Remember to bring a net or pier gaff (but only gaff them if you intend to keep them)! A related, though smaller relative, the banded guitarfish, is occasionally seen at piers in the San Diego area; most are caught from piers in San Diego Bay. (Although I have a picture of one taken at the Goleta Pier north of Santa Barbara).
In Mexico, dead guitarfish are mutilated, shaped, dried, and turned into basilisks or diablos/devils and sold to naive tourists as curios.
