Phylodemography of the Blue Rockfish (Sebastes Mystinus) from California to Washington PHYLODEMOGRAPHY OF THE BLUE ROCKFISH (SEBASTES MYSTINUS) FROM CALIFORNIA TO WASHINGTON A thesis submitted to the faculty of Moss Landing Marine Laboratories and San Francisco State University In partial fulfillment of The requirements for The degree Master of Science In Marine Science by Jason Marc Cope December, 2002 Copyright by Jason Marc Cope 2002 PHYLODEMOGRAPHY OF THE BLUE ROCKFISH (SEBASTES MYSTINUS) FROM CALIFORNIA TO WASHINGTON Jason Marc Cope Moss Landing Marine Laboratories San Francisco State University 2002 Marine resource managers are often challenged with balancing use and sustainability of resources with limited data in dynamic marine environments. Though vagile life history stages are common in marine organisms, increasing evidence indicates intraspecific population substructuring exists in the marine realm. It is also recognized that life history characteristics driving demographic behavior of populations vary spatio- temporally. Spatial and temporal relationships of intraspecific populations must therefore be considered for proper management of these resources, though biological resolution on such levels is often limited. This thesis presents a method by which the combination of limited genetic and demographic information on evolutionary and ecological time scales can produce an historical and contemporary understanding of population dynamics useful for developing management decisions on resources in urgent need of swift management action. I call this approach “phylodemography” and illustrate the method by investigating the spatially distinct subpopulation dynamics of the blue rockfish (Sebastes mystinus) from California to Washington. Genetic samples (N = 245) of blue rockfish from eight sites throughout its range were taken to explore population substructuring. Sequencing of a 498 base pair portion of the mitochondrial DNA control region revealed two major subpopulations of blue rockfish, with the apparent genetic break occurring at Cape Mendocino, CA. This is a relatively unexplored biogeographic break that may reveal a strong barrier for gene flow in other marine species. The northern group is a derivative of the southern group, with the last contact between the two regions occurring 2,000 to 6,000 years ago. With this information, structured subpopulations were then modeled using deterministic and stochastic five stage matrix population models and region specific life history information and vital rates. Demographic and environmental affects (due to intensity-varying El Niño events) were incorporated. Furthermore, genetic pairwise mismatch distributions were used to explore historical population dynamics of each region. The northern population was historically more stable and currently increasing compared to the unstable and most likely decreasing southern population. Age truncation, environmental variability, and fishing pressure are likely driving the southern subpopulation down. Using an introduced time-standardized elasticity method, a 13.5 to 14 inch size limit is recommended for the southern blue rockfish subpopulation to protect the “life history management unit” of the subadult stage and 8 reproductive year classes. The phylodemographic approach shows promise for developing sustainable management schemes for long-lived, slow growing, and late to mature marine organisms where other methods may be inappropriate. The method is also flexible enough to include new types of information on spatial structure and demographic parameters as data accumulate. I certify that the Abstract is a correct representation of the content of this thesis. _____________________________________________ __________________ Gregor M.

SARA is the Act developed by the federal government as a key contribution to the common national effort to protect and conserve species at risk in Canada. SARA came into force in 2003, and one of its purposes is “to manage species of special concern to prevent them from becoming endangered or threatened.” What is a species of special concern? Under SARA, a species of special concern is a wildlife species that could become threatened or endangered because of a combination of biological characteristics and identified threats. Species of special concern are included in the SARA List of Wildlife Species at Risk. What is a management plan? Under SARA, a management plan is an action-oriented planning document that identifies the conservation activities and land use measures needed to ensure, at a minimum, that a species of special concern does not become threatened or endangered. For many species, the ultimate aim of the management plan will be to alleviate human threats and remove the species from the List of Wildlife Species at Risk.

Subsequent morphological studies and DNA barcoding identified it as a false kelpfish, Sebastiscus marmoratus (Cuvier, 1829), a species native to the Western Pacific from southern Hokkaido, Japan to the Philippines. The specimen was a female with a length of 29.2 cm and weighing 453 g. Stomach contents revealed fish remains, as well as the brachyuran Xantho pilipes A. Milne-Edwards, 1867 and remains of anomuran decapods. Parasitological examination revealed infections with the locally common generalist parasites Derogenes varicus (Digenea) and Hysterothylacium aduncum (Nematoda) that likely have been acquired through prey fish. A literature study of the parasites of S. marmoratus was carried out, listing at least 31 species. To the best of our knowledge, this is the first report of this fish species in the Atlantic. The introduction route is unknown, but the most likely possibility is via a ship’s ballast water as a larva or fry, which again would imply that the specimen has been in temperate waters for several years.

  • DESCRIBING DUSKY ROCKFISH (Sebastes Ci/Iatus) HABITAT in the GULF of ALASKA USING HISTORICAL DATA
    DESCRIBING DUSKY ROCKFISH (Sebastes ci/iatus) HABITAT IN THE GULF OF ALASKA USING HISTORICAL DATA A University Thesis Presented to the Faculty of California State University, Hayward In Partial Fulfillment of the Requirements for the Degree Master of Science in Marine Sciences by Rebecca Francesca Reuter March, 1999 Abstract Aspects of dusky rockfish (Sebastes ciliatus) habitat in the Gulf of Alaska are described using historical data sources. In this study Alaskan groundfish fishery data collected by observers between 1990-96 and research survey data collected from three triennial surveys conducted by the National Marine Fisheries Service were used. These two data sets provide data that are essential in the preliminary description of the habitat and ecology of S. ciliatus. Analyses using techniques such as geographic information systems (GIS) to describe the geographic distribution and hierarchical cluster analysis to describe rockfish species associations with S. ciliatus provide results that describe some of the parameters of their essential habitat. S. cilia/us occur in great abundance over localized areas throughout the Gulf of Alaska. Results of analyses using fishery data indicate that fishermen findS. ciliatus in abundance near mouths of submarine gullies/canyons and at deep banks. Analysis of survey data show that areas of S. ciliatus habitat are not adequately sampled, but they do support the results of the fishery data by showing that S. ciliatus do not have a dispersed distribution. The depth range where most adultS. ciliatus aggregations occur are located at I 00 - 200 m. Tllis information may be used to suggest a management scheme that calculates localized quotas for these habitat locations.

CALIFORNIA MARINE FISH LANDINGS FOR 1972 LEO PINKAS Marine Resources Region 1.1. INTRODUCTION The protection, propagation, and wise utilization of California's living marine resources (established as common property by statute, Section 1600, Fish and Game Code) is dependent upon the welding of biological, environment- al, economic, and sociological factors. Fundamental to each of these factors, as well as the entire management pro- cess, are harvest records. The California Department of Fish and Game began gathering commercial fisheries land- ing data in 1916. Commercial fish catches were first published in 1929 for the years 1926 and 1927. This report, the 32nd in the landing series, is for the calendar year 1972. It summarizes commercial fishing activities in marine as well as fresh waters and includes the catches of the sportfishing partyboat fleet. Preliminary landing data are published annually in the circular series which also enumerates certain fishery products produced from the catch.

Hyde1, 2,*, Carol Kimbrell2, Larry Robertson2, Kevin Clifford3, Eric Lynn2, Russell Vetter2 1Scripps Institution of Oceanography, 9500 Gilman Drive, La Jolla, California 92093-0203, USA 2Southwest Fisheries Science Center, NOAA/NMFS, 8604 La Jolla Shores Dr., La Jolla, California 92037, USA 3Oregon Coast Aquarium, 2820 SE Ferry Slip Rd, Newport, Oregon 97365, USA ABSTRACT: The understanding of mating systems is key to the proper management of exploited spe- cies, particularly highly fecund, r-selected fishes, which often show strong discrepancies between census and effective population sizes. The development of polymorphic genetic markers, such as codominant nuclear microsatellites, has made it possible to study the paternity of individuals within a brood, helping to elucidate the species’ mating system. In the present study, paternity analysis was performed on 35 broods, representing 17 species of the live-bearing scorpaenid genus Sebastes. We report on the finding of multiple paternity from several species of Sebastes and show that at least 3 sires can contribute paternity to a single brood. A phylogenetically and ecologically diverse sample of Sebastes species was examined, with multiple paternity found in 14 of the 35 broods and 10 of the 17 examined species, we suggest that this behavior is not a rare event within a single species and is likely common throughout the genus. Despite high variance in reproductive success, Sebastes spp., in general, show moderate to high levels of genetic diversity.
