JELLYFISH FISHERIES of the WORLD by Lucas Brotz B.Sc., The JELLYFISH FISHERIES OF THE WORLD by Lucas Brotz B.Sc., The University of British Columbia, 2000 M.Sc., The University of British Columbia, 2011 A DISSERTATION SUBMITTED IN PARTIAL FULFILLMENT OF THE REQUIREMENTS FOR THE DEGREE OF DOCTOR OF PHILOSOPHY in The Faculty of Graduate and Postdoctoral Studies (Zoology) THE UNIVERSITY OF BRITISH COLUMBIA (Vancouver) December 2016 © Lucas Brotz, 2016 Abstract Fisheries for jellyfish (primarily scyphomedusae) have a long history in Asia, where people have been catching and processing jellyfish as food for centuries. More recently, jellyfish fisheries have expanded to the Western Hemisphere, often driven by demand from buyers in Asia as well as collapses of more traditional local finfish and shellfish stocks. Despite this history and continued expansion, jellyfish fisheries are understudied, and relevant information is sparse and disaggregated. Catches of jellyfish are often not reported explicitly, with countries including them in fisheries statistics as “miscellaneous invertebrates” or not at all. Research and management of jellyfish fisheries is scant to nonexistent. Processing technologies for edible jellyfish have not advanced, and present major concerns for environmental and human health. Presented here is the first global assessment of jellyfish fisheries, including identification of countries that catch jellyfish, as well as which species are targeted. A global catch reconstruction is performed for jellyfish landings from 1950 to 2013, as well as an estimate of mean contemporary catches. Results reveal that all investigated aspects of jellyfish fisheries have been underestimated, including the number of fishing countries, the number of targeted species, and the magnitudes of catches. Contemporary global landings of jellyfish are at least 750,000 tonnes annually, more than double previous estimates. Jellyfish have historically been understudied, resulting in the current dearth of knowledge on population dynamics and jellyfish fishery management. However, many of the tools used in traditional fisheries science, such as length-frequency analysis, can be applied to jellyfish, as demonstrated herein. Research priorities are identified, along with a prospective outlook on the future of jellyfish fisheries. ii Preface This dissertation represents a synthesis of existing information and original work that was led by the author, and includes information contributed from numerous collaborators. The work is presented here in its entirety in order to provide the entire global overview. However, selected material has been extracted as contributions to 6 publications, including 2 peer-reviewed journal articles, 2 book chapters, and 2 report sections. Specifically, selected information formed the basis of a peer-reviewed journal article [Brotz, L., A. Schiariti, J. López-Martínez, J. Álvarez-Tello, Y.-H.P. Hsieh, R.P. Jones, J. Quiñones, Z. Dong, A.C. Morandini, M. Preciado, E. Laaz, & H. Mianzan in press. Jellyfish fisheries in the Americas: origin, state of the art, and perspectives on new fishing grounds. Reviews in Fish Biology and Fisheries doi:10.1007/s11160-016-9445-y]. Information from Chapters 1-3 was used as the basis for a book chapter [Brotz, L. 2016. Jellyfish fisheries – a global assessment, pp. 110-124 in D. Pauly & D. Zeller (eds.) Global Atlas of Marine Fisheries: A Critical Appraisal of Catches and Ecosystem Impacts. Island Press, Washington, D.C., U.S.A.]; which also had an abbreviated version that was published in a report [Brotz, L. 2014. Jellyfish fisheries – a global assessment, pp. 77-81 in D. Pauly & D. Zeller (eds.) So long, and thanks for all the fish: The Sea Around Us, 1999-2014 – A Fifteen-Year Retrospective, a report to the Pew Charitable Trusts, University of British Columbia]. Material gleaned from this dissertation was also combined with additional contributions and was published as a peer-reviewed book chapter [Brotz, L. & D. Pauly in press. Studying jellyfish fisheries: toward accurate national catch reports and appropriate methods for stock assessments in G.L. Mariottini (ed.) Jellyfish: Ecology, Distribution Patterns and Human Interactions. Nova Publishers, Hauppauge, New York, U.S.A.]. A summary of relevant information, especially using selections from Chapter 3, will also be published as a report section [Brotz, L. in press. Jellyfish Fisheries in R. Brodeur & S. Uye (eds.) Jellyfish blooms around the North Pacific Rim: Causes and consequences, PICES Scientific Report No. 51]. iii Finally, some conclusions and opinions related to this dissertation, especially from Chapters 2 and 5, were also expressed in another peer-reviewed journal article [Gibbons, M.J., F. Boero, & L. Brotz 2016. We should not assume that fishing jellyfish will solve our jellyfish problem.

  • Medusa Catostylus Tagi: (I) Preliminary Studies on Morphology, Chemical Composition, Bioluminescence and Antioxidant Activity
    MEDUSA CATOSTYLUS TAGI: (I) PRELIMINARY STUDIES ON MORPHOLOGY, CHEMICAL COMPOSITION, BIOLUMINESCENCE AND ANTIOXIDANT ACTIVITY Ana Maria PINTÃO, Inês Matos COSTA, José Carlos GOUVEIA, Ana Rita MADEIRA, Zilda Braga MORAIS Centro de Polímeros Biomédicos, Cooperativa Egas Moniz, Campus Universitário Quinta da Granja, 2829-511, Portugal, [email protected] The Portuguese continental coast, specially Tejo and Sado estuaries, is the habitat of Catostylus tagi [1]. This barely studied medusa was first described in 1869, by Haeckel, and is classified in the Cnidaria phylum, Scyphozoa class, Rhizostomeae order, Catostylidae family, Catostylus genus. According to the European Register of Marine Species, the referred medusa is the only species of the Catostylidae family found in the European continent [2]. C. tagi is particularly abundant during the summer. Several medusas from the Rhizostomae order are traditionally used as food in some oriental countries [3]. Simultaneously, modern medusa utilizations are related to bioluminescence [4], toxicology [5] and biopolymers [6]. The lack of information on this genus along with the recent discoveries of new marine molecules showing anti-arthritic, anti-inflammatory or antioxidant properties motivated our studies [7]. In addition, the abundant medusa biomass could be evaluated as another natural collagen source, alternative to bovine collagen, with its multiple cosmetic and surgical potential uses [8]. The capture and sample preparation methods were optimized in 2003 [9]. Results reported in this poster relate to 65 animals that were captured in the river Sado in August and September of 2004. Macroscopic aspects, like mass and dimensions, were evaluated as well as their C. tagi by J.Gouveia chemical characteristics.

This study identified the putative toxins of two species of jellyfish—edible jellyfish Rhopilema esculentum Kishinouye, 1891, also known as flame jellyfish, and Amuska jellyfish Sanderia malayensis Goette, 1886. Utilizing nano-flow liquid chromatography tandem mass spectrometry (nLC–MS/MS), 3000 proteins were identified from the nematocysts in each of the above two jellyfish species. Forty and fifty-one putative toxins were identified in R. esculentum and S. malayensis, respectively, which were further classified into eight toxin families according to their predicted functions. Amongst the identified putative toxins, hemostasis-impairing toxins and proteases were found to be the most dominant members (>60%).

  • DOCTORAL THESIS a Physio-Ecological Study of Ephyrae
    DOCTORAL THESIS A Physio-ecological Study of Ephyrae of the Common Jellyfish Aurelia aurita s.l. (Cnidaria: Scyphozoa), with Special Reference to their Survival Capability under Starvation Zhilu Fu Graduate School of Biosphere Science Hiroshima University September 2014 DOCTORAL THESIS A Physio-ecological Study of Ephyrae of the Common Jellyfish Aurelia aurita s.l. (Cnidaria: Scyphozoa), with Special Reference to their Survival Capability under Starvation Zhilu Fu Department of environmental Dynamics and Management Graduate School of Biosphere Science Hiroshima University September 2014 Abstract The moon jellyfish Aurelia aurita s.l. is the most common scyphozoan jellyfish in the coastal waters around the world, and the mass occurrences of this species have been reported from various regions. In recent decades, A. aurita blooms have become increasingly prominent in East Asian seas, causing serious problems to human sectors such as fisheries and coastal power plant operations. Therefore, it is important to identify causes for the enhancement of A. aurita populations to forecast likely outbreaks prior to the season of medusa blooms. In the population dynamics of scyphozoan jellyfish, the following two factors are important to determine the size of adult (medusa) population: (1) the abundance of benthic polyps, which reproduce asexually and undergo seasonal strobilation to release planktonic ephyrae, and (2) the mortality of ephyrae before recruitment to the medusa stage. Although much knowledge has been accumulated about physio-ecology of the polyp stage by previous studies, only few studies have been conducted for the ephyra stage. The success for survival through larval stage is basically affected by two factors, viz. food availability and predation.

To evaluate starvation resistance in first-feeding ephyrae of the moon jellyfish Aurelia aurita s.l., we determined their point of no return (PNR50), i.e. days of starvation after which 50% of ephyrae die even if they then feed. PNR50 values were 33.8, 38.4 and 58.6 d at 15, 12 and 9°C, respectively. Before reaching PNR50, the ephyrae showed significant body size reduc- tion: ca. 30 and 50% decrease in disc diameter and carbon content, respectively. These PNR50 val- ues are nearly 1 order of magnitude longer than those of larval marine molluscs, crustaceans and fishes, which is attributable to the ephyra’s extremely low metabolic (i.e. respiration) rate relative to its copious carbon reserves. Such a strong endurance under prolonged starvation is likely an adaptive strategy for A. aurita ephyrae, the release of which is programmed to occur during the annual period of lowest temperatures, allowing them to cope with the concomitant seasonal food scarcity.

Recently, however, the life cycle of the cubomedusa, Tripedalia cystophora became clear by WERNER, CuTRESS and STUDEBACKER (1971) and it was established that the Cubomedusae only stand in a quite separate position from other orders of Scyphomedusae. On the other hand, WERNER who published several papers on the Scyphozoan polyp, Stephanoscyphus (1966-1971) laid stress on the fact that Stephanoscyphus can be linked directly with the extinct fossil group of the Conulata and concluded that the Coronatae represent the most basic group of all living Scyphomedusae with the exception of Cubomedusae. Such being the case, the systematic position of the Stauromedusae remains proble­ matical. The present writer is of the opinion that the Stauromedusae are to be entitled to the Ephyridae and are closely related to the Discomedusae, though there occurs no strobilation in the order. The body of Stauromedusae is composed of two parts; the upper octomerous medusan part and the lower tetramerous scyphistoma portion. No strobilation and no ephyra. Throughout their life history, they lack pelagic life entirely; an egg develops to the solid blastula, which becomes to the planula.

Abstract: Spatial and temporal abundance and distribution of Stomolophus meleagris (Rhizostomae: Stomolophidae) in a lagoon system Southern Gulf of Mexico. The scyphomedusae feed mainly on micro- scopic crustaceans, eggs and fish larvae, molluscs and some other jellyfishes. The distribution and abundance of the scyphomedusae has an economic and ecological impact as they are predators that have an influence on the population dynamics of other fisheries. This investigation took place in the lagoon system ‘Arrastradero- Redonda’, Tabasco, from September 2013 to August 2014, with the purpose to provide information on the distri- bution, and spatial and temporal abundance of Stomolophus meleagris; along with its relation to environmental parameters. A total of 10 stations were defined and biological samples were taken on a monthly basis during this annual cycle. For this purpose, three pulls with a beach seine monofilament (20 m long by 3 m height, mesh opening 1.5 cm, 5 to 10 minutes) per station were made within a 1 km2 area.

Life- history traits of Chloroscombrus chrysurus (Actinopterygii: Perciformes: Carangidae) in tropical waters of the Atlantic Ocean. Acta Ichthyol. Piscat. 48 (1): 1–8. Background. In fishery biology, information on life-history traits is extremely useful for species conservation and the monitoring, management and sustaining of fish stocks. Nevertheless, detailed biological information is very limited for tropical fishes, especially for those with low economic value, such as the Atlantic bumper, Chloroscombrus chrysurus (Linnaeus, 1766). This species is commonly captured by artisanal fisheries in tropical waters and the lack of information makes difficult the development of strategies for the proper management of the species. Therefore, the presently reported study intended to provide new data on the biological parameters of C. chrysurus to fill the gap in the existing knowledge. Materials and methods. Life-history traits of the Atlantic bumper, C. chrysurus, were estimated from 335 fish collected in a western Atlantic region during fishery surveys carried out between 2010 and 2012.
