  • Genetic Identification of Octopodidae Species in Southern California Seafood Markets: Species Diversity and Resource Implications

    Genetic Identification of Octopodidae Species in Southern California Seafood Markets: Species Diversity and Resource Implications

    Genetic Identification of Octopodidae Species in Southern California Seafood Markets: Species Diversity and Resource Implications Chase Martin Center for Marine Biodiversity and Conservation Scripps Institution of Oceanography University of California San Diego Abstract Various species of Octopodidae are commonly found in seafood markets throughout Southern California. Most of the octopus available for purchase is imported, with the majority of imports coming from various Asian nations. Despite the diversity of global octopus species, products are most commonly labeled as simply “octopus,” with some distinctions being made in size, e.g., “baby” or “little octopus.” In efforts to characterize species diversity, this study genetically tested 59 octopus samples from a variety of seafood markets in Los Angeles, Orange, and San Diego Counties. Universal 16S rRNA primers (ref) and CO1 primers developed by Folmer et al. (1994) were used for PCR amplification and sequencing of mtDNA. In all, 105 sequences were acquired. Seven species were identified with some confidence. Amphioctopus aegina was the most prevalent species, while two additional species were undetermined. Little available data exists pertaining to octopus fisheries of the countries of production of the samples. Most available information on octopus fisheries pertains to those of Mediterranean and North African nations, and identifies the Octopus vulgaris as the fished species. Characterizing octopus diversity in Southern California seafood markets and assessing labeling and countries of production provides the necessary first step for assessing the possible management implications of these fisheries and seafood supply chain logistics for this group of cephalopods. Introduction Octopuses are exclusively marine cephalopod mollusks that form the order Octopoda.

    Changing Jellyfish Populations: Trends in Large Marine Ecosystems

    CHANGING JELLYFISH POPULATIONS: TRENDS IN LARGE MARINE ECOSYSTEMS by Lucas Brotz B.Sc., The University of British Columbia, 2000 A THESIS SUBMITTED IN PARTIAL FULFILLMENT OF THE REQUIREMENTS FOR THE DEGREE OF MASTER OF SCIENCE in The Faculty of Graduate Studies (Oceanography) THE UNIVERSITY OF BRITISH COLUMBIA (Vancouver) October 2011 © Lucas Brotz, 2011 Abstract Although there are various indications and claims that jellyfish have been increasing at a global scale in recent decades, a rigorous demonstration to this effect has never been presented. As this is mainly due to scarcity of quantitative time series of jellyfish abundance from scientific surveys, an attempt is presented here to complement such data with non- conventional information from other sources. This was accomplished using the analytical framework of fuzzy logic, which allows the combination of information with variable degrees of cardinality, reliability, and temporal and spatial coverage. Data were aggregated and analysed at the scale of Large Marine Ecosystem (LME). Of the 66 LMEs defined thus far, which cover the world’s coastal waters and seas, trends of jellyfish abundance (increasing, decreasing, or stable/variable) were identified (occurring after 1950) for 45, with variable degrees of confidence. Of these 45 LMEs, the overwhelming majority (31 or 69%) showed increasing trends. Recent evidence also suggests that the observed increases in jellyfish populations may be due to the effects of human activities, such as overfishing, global warming, pollution, and coastal development. Changing jellyfish populations were tested for links with anthropogenic impacts at the LME scale, using a variety of indicators and a generalized additive model. Significant correlations were found with several indicators of ecosystem health, as well as marine aquaculture production, suggesting that the observed increases in jellyfish populations are indeed due to human activities and the continued degradation of the marine environment.

    The Form and Function of the Hypertrophied Tentacle of Deep-Sea Jelly Atolla Spp

    The Form and Function of the Hypertrophied Tentacle of Deep-Sea Jelly Atolla spp. Alexis Walker, University of California Santa Cruz Mentors: Bruce Robison, Rob Sherlock, Kristine Walz, and Henk-Jan Hoving, George Matsumoto Summer 2011 Keywords: Atolla, tentacle, histology, SEM, hypertrophied ABSTRACT In situ observations and species collection via remotely operated vehicle, laboratory observations, and structural microscopy were used with the objective to shed light on the form and subsequently the function of the hypertrophied tentacle exhibited by some Atolla species. Based upon the density of nematocysts, length, movement, and ultrastructure of the hypertrophied tentacle, the function of the tentacle is likely reproductive, sensory, and/or utilized in food acquisition. INTRODUCTION The meso- and bathypelagic habitats are of the largest and least known on the planet. They are extreme environments, characterized by high atmospheric pressure, zero to low light levels, scarcity of food sources, and cold water that is low in oxygen content. Animals that live and even thrive in these habitats exhibit unique characteristics enabling them to survive in such seemingly inhospitable conditions. One such organism, the deep- sea medusa of the genus Atolla, trails a singular elongated tentacle, morphologically 1 distinct from the marginal tentacles. This structure, often referred to as a trailing or hypertrophied tentacle, is unique within the cnidarian phylum. Ernst Haeckel described the first species of this deep pelagic jelly, Atolla wyvillei, during the 1872-1876 HMS Challenger Expedition. In the subsequent 135 years, the genus Atolla has expanded to several species not yet genetically established, which have been observed in all of the worlds oceans (Russell 1970).

    CNIDARIA Corals, Medusae, Hydroids, Myxozoans

    FOUR Phylum CNIDARIA corals, medusae, hydroids, myxozoans STEPHEN D. CAIRNS, LISA-ANN GERSHWIN, FRED J. BROOK, PHILIP PUGH, ELLIOT W. Dawson, OscaR OcaÑA V., WILLEM VERvooRT, GARY WILLIAMS, JEANETTE E. Watson, DENNIS M. OPREsko, PETER SCHUCHERT, P. MICHAEL HINE, DENNIS P. GORDON, HAMISH J. CAMPBELL, ANTHONY J. WRIGHT, JUAN A. SÁNCHEZ, DAPHNE G. FAUTIN his ancient phylum of mostly marine organisms is best known for its contribution to geomorphological features, forming thousands of square Tkilometres of coral reefs in warm tropical waters. Their fossil remains contribute to some limestones. Cnidarians are also significant components of the plankton, where large medusae – popularly called jellyfish – and colonial forms like Portuguese man-of-war and stringy siphonophores prey on other organisms including small fish. Some of these species are justly feared by humans for their stings, which in some cases can be fatal. Certainly, most New Zealanders will have encountered cnidarians when rambling along beaches and fossicking in rock pools where sea anemones and diminutive bushy hydroids abound. In New Zealand’s fiords and in deeper water on seamounts, black corals and branching gorgonians can form veritable trees five metres high or more. In contrast, inland inhabitants of continental landmasses who have never, or rarely, seen an ocean or visited a seashore can hardly be impressed with the Cnidaria as a phylum – freshwater cnidarians are relatively few, restricted to tiny hydras, the branching hydroid Cordylophora, and rare medusae. Worldwide, there are about 10,000 described species, with perhaps half as many again undescribed. All cnidarians have nettle cells known as nematocysts (or cnidae – from the Greek, knide, a nettle), extraordinarily complex structures that are effectively invaginated coiled tubes within a cell.
