Coastal Fish Identification: California

Common Thresher SharkFamily: Squalidae (Dogfish sharks)

Genus and Species: Squalus acanthias

Description: The body of the spiny dogfish is elongate and slender. The head is pointed. The color is slate gray to brownish on top, sometimes with white spots, becoming white below. This species and the horn shark are the only sharks along the California coast with spines at the beginning of both dorsal fins. These spines may be mildly poisonous and provide a defense for the spiny dogfish.

Range: Spiny dogfish occur in temperate to subarctic waters in the Atlantic and Pacific Oceans. In the eastern Pacific Ocean they are found off Chile, and from central Baja California to Alaska and to Japan. This species is common in nearshore waters along most of the coast.Spiny Dogfish have been taken to depths of 2, 400 feet.

Natural History: The spiny dogfish feeds upon practically all smaller fishes such as herring, sardines, anchovies, smelts and even small spiny dogfish as well as crabs. The females are larger than the males, and produce from 3 to 14 young at a time and in alternate years. Most adults are 2 to 4 feet long. Spiny dogfish are long lived and non-migratory; as a result, heavy fishing pressure in a given area will lower the population level of this slow growing, low reproductive species quite rapidly.

Fishing Information: You are most likely to catch a spiny dogfish with anchovies or invertebrates on a rock cod jig.

Shortfin Mako or Bonito SharkOther Common Names: dog shark, grayfish, Pacific grayfish, spinarola, California dogfish.

Largest Recorded: 5.25 feet; no weight recorded; however, a large fat female about 4 feet long will weigh 15 pounds.

Habitat: Shallow Sandy Environment

Family: Alopiidae (Thresher sharks)

Genus and Species: Alopias vulpinus

Description: The body of the common thresher shark is moderately elongate. The snout is rather short, and the mouth crescent shaped. The first dorsal fin is large, and located midway between the pectoral and ventral fins. The second dorsal and anal fins are very small. The tail is distinctive since it is very long, almost as long as the rest of the body. The coloration may vary from brownish gray, bluish or blackish above to silvery, bluish or golden below. The dorsal, pectoral and ventral fins are blackish and sometimes the pectoral and ventral fins have a white dot in the lip. The bigeye thresher also occurs off the California coast. It can be distinguished by its large eye; however, if you can count the teeth in the upper jaw, the common thresher has 21 - 22 on each side while the bigeye thresher has 10 - 11 on each side.

Catching WHITES -2

Lake whitefish generally spawn in the late autumn just prior to freeze-up in shallow water (often less than 25 feet), usually over a hard or stony bottom, but sometimes over sand. Spawning can occur under the ice in some lakes, however. What does this tell you? Well, like most fish, spent adults are hungry following the spawning season. Often the best lake whitefish catches are shortly after they spawn in the month of December, just when the ice is safe to travel on. Use caution on ice and always test the conditions. Never walk on ice that is less than four inches thick and don't drive on ice that is less than 12 inches thick
