FisElermcn returning froln fishing trips were interviewed at launch ramps, hoists, and boat rental facilities. This report contains quantitative data and statistical estimates of total eCfort, tot:il catch, catch of preferred species, and length frequencies for tilose species xrhose catches are regulated by minimum size limits An estimated 139,000 organisms were landed by 45,000 anglers and 1,900 divers. The major components of the catch were Pacific mackerel, Scornber japonicus, 29,000 landed ; white cro~lccr, Genyonetnzis Lineatus, 27,000 landed ; and Pacific bonito, Sard? chiZiensis, 13,000 landed. These three species con~prisedone-half of the total catch. Anglers' compliance with size limit regulations was variable. Approximately 87% of all measured bass, Pm~aZabraxspp.,,were legal size, but only 60% of the California halibut, Paralichthys californicus, were legal size. Divers showed much better compliance with the size limit regulations: 96% of all red abalone, HaZiotis rufescens, were legal size. -I/ Marine Resources Region, Administrative Report No. 81-6 -2/ Marine Resoiurces Region, California State Fisheries Laboratory, 350 Golden Shore, Long Beach, California 90802. -3/ ~arineResources Region, 1350 Front Street, Room 6042, San Diego, California 92101. hCKNtll.?L,E CGPII': MT This worlc was performed as part of Dingell-3okin:;on project F-35-R, the Southern Ca1iforrli.a Marine Sportfish Monitoring Progz.:?rn, which was supported in part by Fccleral Aid to Fish Restoration Funds. 1NTRODUCICIO;J . l?rcreriti.ons~l. flsh~ngnct:i.vities i.n sou!:licrn C.llifornia inarirlc waters ai;?ecil the aLunilancc of 1cic:il Eisll populatioris artd also i1.1Eluencc r,1igr,tr?rg Ei.sh populations.

    NEGATIVELY CORRELATED ABUNDANCE SUGGESTS COMPETITION BETWEEN RED ABALONE (Haliotis rufescens) AND RED SEA URCHINS (Mesocentrotus franciscanus) INSIDE AND OUTSIDE ESTABLISHED MPAs CLOSED TO COMMERCIAL SEA URCHIN HARVEST IN NORTHERN CALIFORNIA By Johnathan Centoni A Thesis Presented to The Faculty of Humboldt State University In Partial Fulfillment of the Requirements for the Degree Master of Science in Biology Committee Membership Dr. Sean Craig, Committee Chair Dr. Brian Tissot, Committee Member Dr. Paul Bourdeau, Committee Member Dr. Joe Tyburczy, Committee Member Dr. Erik Jules, Program Graduate Coordinator May 2018 ABSTRACT NEGATIVELY CORRELATED ABUNDANCE SUGGESTS COMPETITION BETWEEN RED ABALONE (Haliotis rufescens) AND RED SEA URCHINS (Mesocentrotus franciscanus) INSIDE AND OUTSIDE ESTABLISHED MPAs CLOSED TO COMMERCIAL SEA URCHIN HARVEST IN NORTHERN CALIFORNIA Johnathan Centoni Red abalone and sea urchins are both important herbivores that potentially compete with each other for resources like food and space along the California coast. Red abalone supported a socioeconomically important recreational fishery during this study (which was closed in 2018) and red sea urchins support an important commercial fishery. Both red sea urchins and red abalone feed on the same macroalgae (including Pterygophora californica, Laminaria setchellii, Stephanocystis osmundacea, Costaria costata, Alaria marginata, Nereocystis leutkeana), and a low abundance of this food source during the period of this project may have created a highly competitive environment for urchins and abalone. Evidence that suggests competition between red abalone and red sea urchins can be seen within data collected during the years of this study (2014-2016): a significantly higher red sea urchin density, concomitant with a significantly lower red abalone density, was observed within areas closed to commercial sea urchin harvest (in MPAs) compared to nearby reference areas open to sea urchin harvest.

  • Vii Fishery-At-A-Glance: California Sheephead
    Fishery-at-a-Glance: California Sheephead (Sheephead) Scientific Name: Semicossyphus pulcher Range: Sheephead range from the Gulf of California to Monterey Bay, California, although they are uncommon north of Point Conception. Habitat: Both adult and juvenile Sheephead primarily reside in kelp forest and rocky reef habitats. Size (length and weight): Male Sheephead can grow up to a length of three feet (91 centimeters) and weigh over 36 pounds (16 kilograms). Life span: The oldest Sheephead ever reported was a male at 53 years. Reproduction: As protogynous hermaphrodites, all Sheephead begin life as females, and older, larger females can develop into males. They are batch spawners, releasing eggs and sperm into the water column multiple times during their spawning season from July to September. Prey: Sheephead are generalist carnivores whose diet shifts throughout their growth. Juveniles primarily consume small invertebrates like tube-dwelling polychaetes, bryozoans and brittle stars, and adults shift to consuming larger mobile invertebrates like sea urchins. Predators: Predators of adult Sheephead include Giant Sea Bass, Soupfin Sharks and California Sea Lions. Fishery: Sheephead support both a popular recreational and a commercial fishery in southern California. Area fished: Sheephead are fished primarily south of Point Conception (Santa Barbara County) in nearshore waters around the offshore islands and along the mainland shore over rocky reefs and in kelp forests. Fishing season: Recreational anglers can fish for Sheephead from March 1through December 31 onboard boats south of Point Conception and May 1 through December 31 between Pigeon Point and Point Conception. Recreational divers and shore-based anglers can fish for Sheephead year round.

  • California Spiny Lobster Scientific Name: Panulirus Interruptus Range
    Fishery-at-a-Glance: California Spiny Lobster Scientific Name: Panulirus interruptus Range: Spiny Lobster range from Monterey, California southward to at least as far as Magdalena Bay, Baja California. The physical center of the range is within Mexico, and population density and fishery productivity is highest in this area. Habitat: As juveniles (less than 3 years of age), Spiny Lobster live in coastal rubble beds, but as adults, they are found on hard bottomed or rocky-reef habitat kelp forests. Size (length and weight): Adult Spiny Lobsters average 2 pounds in weight and about 12 inches total length, with males slightly larger than females. Adults more than 5 pounds are currently considered trophy individuals, although records exist from a century ago of 26 pound, 3 foot long lobsters. Life span: Spiny Lobsters can live up to 30 to 50 years. Reproduction: Spiny Lobsters mature at about 5 years of age, or 2.5-inch carapace length. They have a complex, 2-year reproductive cycle from mating to the settlement of juvenile lobsters. Fecundity increases with size, and females produce one brood of eggs per year. Prey: Spiny Lobsters are omnivorous, and act as important keystone predators within the southern California nearshore ecosystem. Adults forage at night for algae, fish, and many marine invertebrates. Predators: Predators of juvenile Spiny Lobsters include California Sheephead, Cabezon, rockfishes, Kelp Bass, Giant Sea Bass, and octopus. Predators of adult lobsters tend to be the larger individuals such as male California Sheephead and Giant Sea Bass. Fishery: The commercial fishery accounted for approximately 312 metric tons (688,000 lb) in ex- vessel landings and $12.7 million in ex-vessel value during the 2017-2018 fishing season.

  • Bony Fish Classification
    Reading Handout: Bony Fish Scientific Classification The information below shows the scientific classification of bony fishes that still exist today. KINGDOM Animalia PHYLUM Chordata SUBPHYLUM Vertebrata CLASS Actinopterygii (old name = Osteichthyes) Class Actinopterygii includes all the bony fishes that are ray-finned (vs. lobed-finned, Class Sarcopterygii). Bony fishes are ectothermic (cold-blooded) and are vertebrates (have a spine/backbone). Most bony fishes have scales, breathe with gills, have fins (lacking in some), and have a two-chambered heart. Most bony fishes lay eggs. Actinopterygians are the dominant class of vertebrates, comprising nearly 99% of the over 30,000 species of fishes. They are found in both freshwater and marine environments and from the deep sea to the highest mountain streams. Extant species can range in size from a minnow, at 8 mm (0.3 in), to the massive ocean sunfish, at 2,300 kg (5,070 lb), and the long-bodied oarfish, at 11 m (36 ft). INFRACLASS Teleostei Teleostei is one of three infraclasses in Class Actinopterygii, the ray-finned fishes. This diverse group, which arose in the Triassic period, includes 26,840 extant species in about 40 orders and 448 families; most living fishes are members of this group.

  • California Spiny Lobster, Panulirus Interruptus
    1 California Spiny Lobster, Panulirus interruptus California spiny lobster, Panulirus interruptus. Credit: D Stein, CDFW. History of the Fishery California spiny lobster, Panulirus interruptus, have been fished in southern California since at least 1872. The commercial fishery originated in Santa Barbara County and expanded as the number of fishermen increased. By 1900, the fishery encompassed the entire Southern California Bight (SCB) and most of the offshore islands. Today’s lobster population is the product of a century of commercial fishing with few areas historically off limits to fishermen. Over the decades commercial landings have fluctuated, reaching a high in the early 1950s, followed by a decline until the mid 1970s (Figure 1-1). There were multiple reasons for this decline, but a major contributing factor was the landing of sub-legal size (short) lobster. Recognizing this problem, in 1957 the California Department of Fish and Wildlife (Department) implemented a minimum 2 inch by 4 inch (5 centimeter by 10.2 centimeter) mesh size requirement for commercial traps specifically to reduce the taking of short lobster. However, this gear requirement did not fully solve the problem. Consequently, in 1976, the Department required an escape port in all commercial traps. The size of this horizontal escape port enables a short lobster to freely exit the trap. Requiring escape ports addressed the immediate problem of landing short lobster and initiated the rebuilding of the spawning stock, allowing for an associated increase in the number of legal size lobster entering the fishery. Beginning in 1976, total landings improved each season (October through March), reaching a high of 952,000 pounds (432 metric tons) during the 1997/98 season.
