The daily bag and possession limit is 3 fish with a minimum size limit of 36 inches total length. It may live for over 20 years in captivity. The pectoral fins are wide and triangular. [3] The tooth rows number 41–55 in the upper jaw and 34–45 in the lower jaw; each tooth has a slightly oblique, smooth-edged cusp in the center and 1–2 small cusplets on either side. These management measures seem to have successfully reduced fishing mortality and halted the population decline from the 1980s; the status of the leopard shark off California is regarded as secure, with demographic models estimating an annual population increase of 3–6% with sustainable fishing.[7]. Min. On occasion, the shark tears the entire clam body out of its shell this way. [9] Off Baja California, the leopard sharks on the Pacific side are probably distinct from those in the northern Gulf of California. The department will provide a news release notifying the public 10 calendar days in advance of a change for this species made under the authority of subsection 27.20(e). 5. [10] Rarely males may grow to 1.5 m (4.9 ft) and females 1.8 m (5.9 ft), and there is a record of an exceptional female that measured 2.1 m (6.9 ft) long. The reported maximum estimated age for a leopard shark is 30 years. 8. 19). [3], The leopard shark is aplacental viviparous, with the developing embryos sustained by a yolk sac until birth. This may be an adaptation for foraging in deoxygenated estuary environments. This species is caught by commercial fisheries using gillnets and longlines, and by recreational anglers and spearfishers; it is also caught as bycatch in bottom trawls. shallow nearshore sub-limit. [5] Individuals of the same age can vary significantly in size and large sharks are especially slow-growing: one specimen was documented to have gained only 4 cm (1.6 in) in length over 12 years. The International Union for Conservation of Nature has assessed this species as of Least Concern, while noting that local stocks may easily become overfished because of the shark's slow growth and limited migratory habits. View a summary table of groundfish regulations. Males mature a little earlier at about the age between seven to 13 years at 100 to 105 cm long. The sport fishery for leopard shark inside San Francisco Bay, Bodega Harbor, Tomales Bay, Bolinas Bay, and Drake’s Bay is exempt from season and depth restrictions that affect other federally managed groundfish (Section 28.56). 4. Wary and quick to flee, leopard sharks pose almost no danger to humans. 10). [7], The International Union for Conservation of Nature (IUCN) has assessed the leopard shark as of Least Concern. 20). The leopard shark (Triakis semifasciata) is a species of houndshark, in the family Triakidae. There is a single record from 1955 of a leopard shark harassing a skin diver with a nosebleed, though no injuries resulted. Depth Limit 1, 2, 3.

[5] The heaviest known leopard shark weighed 18.4 kg (41 lb). [5] Other sharks examined have had stomachs containing whole innkeeper worms with no bite marks, suggesting that the sharks sucked them out of their burrows. [17] This species contributes negligibly to fishery landings off Oregon. The leopard shark is part of a group of fish known as groundfish, which includes over 90 species that live on or near the bottom of the ocean (with a few exceptions). The shark is most commonly encountered in 20 feet (6.1 meters) of water or less but has been sighted up to 300 feet (91.4 meters) deep. [7] Although there is equivocal evidence for natal philopatry (returning to one's birthplace to breed) in this species, proximity to established breeding grounds likely contributes to the structuring of these different subpopulations. [12], From birth, leopard sharks form large schools generally segregated by age and sex, which may intermingle with grey or brown smoothhounds (Mustelus californicus and M. henlei) or spiny dogfish (Squalus acanthias). Length Max Catch/ Person All other flat fish (ex: rock sole, butter sole, english sole, dover sole, rex sole, turbit, tongue fish) … [3] A 2006 phylogenetic analysis by J. Andrés López and colleagues, based on protein-coding genes, revealed that Triakis and Cazon are in fact not closely related, and additionally that the leopard shark may be the most basal member of its family. There are furrows at the corners of the mouth extending onto both jaws, with those on the lower jaw almost long enough to meet at the midline. [29], Newborn leopard sharks measure around 20 cm (7.9 in) long. Requested move. Reference: Sections 200, 202, 205, 206 and 1802, Fish and Game Code; 50 CFR Part 660, Subpart G; 50 CFR 660.384; and 14 CCR 27.20. Though this is a fairly light level of fishing for a common species, leopard sharks take a long time to grow to maturity—about a decade. [7], Most of the fishing for leopard sharks occurs in the waters off California, where commercial landings peaked at 45,953 kg (101,309 lb) in 1983 and has averaged 14,060 kg (31,000 lb) annually since 1991. Polluted water can pollute fish [9], Females give birth to 1–37 young annually from March and July (most in April or May), with the number of pups increasing with female size. The leopard shark is part of a group of fish known as groundfish, which includes over 90 species that live on or near the bottom of the ocean (with a few exceptions).

They swim up and down our beaches, specifically during the months of June through September. In recent decades the number of sharks taken recreationally has exceeded those taken commercially, with sport fishers catching an average of 52,000 sharks per year from 1980–1988, and 45,000 sharks per year since 1993. [16] Small leopard sharks fall prey to larger sharks such as the great white shark (Carcharodon carcharias) and the broadnose sevengill shark (Notorynchus cepedianus). The leopard shark is part of a group of fish known as groundfish, which includes over 90 species that live on or near the bottom of the ocean (with a few exceptions).

Once the subject of a developing fishery, it became the leading food shark in 1985-86, after which time a size limit was imposed and much of inshore fishing effort was curtailed after a voter initiative banned gillnetting inshore of 3 miles. View a … The average length of a leopard shark is between 1.2 and 1.5 meters, although some females can reach 1.9 meters long. However, Gray did not furnish the name with a proper description, rendering it a nomen nudum. (2009). Phylogenetic relationships of houndsharks, based on protein-coding gene sequences. [3][10] This species is caught by commercial fisheries using gillnets and longlines, and by recreational anglers and spearfishers; it is also caught as bycatch in bottom trawls. salinity and leopard shark die-offs, a continuation of the size limit on catches, and a potential no take, especially during the parturition and breeding season following heavy winter rains is recommended to avoid contributing to population losses that may occur innkeeper worms and cancrid crabs in Tomales Bay, jack silverside (Atherinopsis californiensis) eggs and the crabs Romaleon antennarium and Metacarcinus magister in Humboldt Bay). The vast majority of these sharks are female and are attracted to San Diego’s warm water temps as they attempt to maintain a comfortable body temperature for the pups they carry in preparation of spawning. In 1993, the State also instituted a minimum size limit of 46 cm (18 in) for the commercial harvesting of all sharks and rays, including for the aquarium trade. Copyright © 2020 by eLaws.

Here in San Diego (specifically La Jolla), we are lucky enough to have an abundance of leopard sharks that call the Cove home. 53). [3] In captivity, larger sharks have been observed establishing their dominance over smaller individuals via light nips to the pectoral fins. Minimum size limit: 30 inches total length; daily bag limit: one fish * The leopard shark sport fishery inside San Francisco Bay is open from May through December at all depths. The lower lobe of the caudal fin is well-developed in adults but less than half the length of the upper lobe, which has a strong ventral notch near the tip. [6], The leopard shark occurs in the Northeastern Pacific Ocean, from the temperate continental waters of Coos Bay, Oregon to the tropical waters of Mazatlán, Mexico, including the Gulf of California. ... Leopard shark may be taken or possessed in Humboldt Bay year-round. [7], Wary and quick to flee, leopard sharks pose almost no danger to humans. Leopard shark. They are caught on virtually every southern California pier, in the surf and in bays. [17] The meat is considered excellent eating and is sold fresh or frozen. Of these, the Humboldt Bay subpopulation is perhaps the most isolated, with the sharks there maturing at a larger size and producing fewer offspring than those from other areas. Leopard sharks have slender but stout bodies, making it easy for them to maneuver. Fishery Bulletin, U.S. 88:371-381. 35). Ocean and San Francisco Bay District, Fin Fish-Minimum Size Limits, Bag and Possession Limits and Seasons. The status of leopard sharks off Mexico is uncertain, although Mexican shark fisheries tend to focus more on larger species. Because of its looks, the leopard shark is also a popular aquarium fish — just remember that fish below this size limit are illegal if they came from California waters. The listed record is 61.5 inches and 40 pounds although I personally have seen several that approached or may have exceeded that size. Fish, Amphibians and Reptiles, Article 1. [1] It is highly susceptible to local depletion due to its slow growth rate and low level of exchange between regional stocks. [10], The large first dorsal fin is positioned about halfway between the pectoral and pelvic fins; the second is almost as large as the first and much larger than the anal fin. Most of the fish will go between 5 and 15 pounds with an occasional fish approaching 30 pounds or even greater size. Froese, Rainer and Pauly, Daniel, eds. This low level of dispersal has led to genetic divergence across its range. Commercial sportfishing boat catches of leopard shark in California have dropped from an average of 6.8 fish per trip between 1980-91 to an average of 4.0 fish after the size limit was imposed 1992-95, as more fish are being released (Kevin Hill pers.

The daily bag and possession limit is 3 fish with a minimum size limit of 36 inches total length. Numbers have been known to gather near discharges of warm effluent from power plants. Seven discrete gene pools have been identified along the Californian coast between Humboldt Bay and San Diego. Leopard Shark Hook Size. As these females follow the warmest patches of water, allowing them to raise their internal body temperatures by up to 3 °C (5.4 °F), they are speculated to be taking advantage of the heat to speed their growth and that of their gestating young. [7] During summer days, large aggregations of mature females assemble in shallow bays and estuaries, dispersing at night. This opportunistic hunter has also been known to eat ghost shrimp, polychaete worms, and the young of smoothhounds, shovelnose guitarfish (Rhinobatos productus), and bat rays (Myliobatis californicus). [26][27] The predominant prey taken depends on location, time of year, and age. (5) Southern Groundfish Management Area: Open March 1 through December 31, in waters shallower than 50 fathoms, except that take and possession is authorized year-round in Newport Bay, Alamitos Bay, Mission Bay, and San Diego Bay. Mendocino Groundfish Management Area. [3][12] In Tomales Bay and elsewhere, the leopard shark follows the tide onto mudflats to forage for food, retreating just fast enough to prevent being stranded or trapped as the water recedes. (3) San Francisco Groundfish Management Area: Open June 1 through December 31, in waters shallower than 30 fathoms, except that take and possession is authorized year-round in Drake's Estero Bay, Bolinas Bay, Tomales Bay, Bodega Harbor, and San Francisco Bay. In federal waters, leopard sharks are one of three shark species under the management authority of the National Oceanic and Atmospheric Administration (NOAA) National Marine Fisheries Service through the Pacific Coast Groundfish Fishery Management Plan (Groundfish FMP).
