  • Carcinus Maenas in South Africa: Status, Impacts and Management
    Carcinus maenas in South Africa: status, impacts and management Clova Airth Mabin Dissertation presented for the degree of Doctor of Philosophy (Zoology) Department of Botany and Zoology Stellenbosch University Supervisor: Dr Tammy Robinson-Smythe Co-supervisors: Prof John Wilson Prof Jaco Le Roux March 2018 Stellenbosch University https://scholar.sun.ac.za Declaration By submitting this dissertation electronically, I declare that the entirety of the work contained therein is my own, original work, that I am the sole author thereof (save to the extent explicitly otherwise stated), that reproduction and publication thereof by Stellenbosch University will not infringe any third-party rights and that I have not previously in its entirety or in part submitted it for obtaining any qualification. I would like to declare that Dr Henning Winker at the Department of Agriculture, Forestry and Fisheries developed the code for the Bayesian depletion model used in Chapter 3. This allowed me to use the data collected during management of Carcinus to estimate the population’s response to the intervention. Throughout the thesis, the term Carcinus is used when referring to South African populations of crabs from this genus. This is a result of the detection of hybrids between C. maenas and C. aestuarii in Chapter 5, and the recognition that the results obtained in this thesis can thus not be ascribed to a particular Carcinus species. During the management programme, I played the role of lead scientist, co-ordinating the research and contributing to decisions regarding the management plan. During the course of my doctoral studies, I also completed the field work for and published the following paper: Mabin CA, Wilson JR, Robinson TB (2015) The Chilean black urchin, Tetrapygus niger (Molina, 1782) in South Africa: gone but not forgotten.

  • Catching the Complexity of Salmon-Louse Interactions
    Fish and Shellfish Immunology 90 (2019) 199–209 Contents lists available at ScienceDirect Fish and Shellfish Immunology journal homepage: www.elsevier.com/locate/fsi Full length article Catching the complexity of salmon-louse interactions T ∗ Cristian Gallardo-Escáratea, , Valentina Valenzuela-Muñoza, Gustavo Núñez-Acuñaa, Crisleri Carreraa, Ana Teresa Gonçalvesa, Diego Valenzuela-Mirandaa, Bárbara P. Benaventea, Steven Robertsb a Interdisciplinary Center for Aquaculture Research, Laboratory of Biotechnology and Aquatic Genomics, Department of Oceanography, Universidad de Concepción, Concepción, Chile b School of Aquatic and Fishery Sciences (SAFS), University of Washington, Seattle, USA ABSTRACT The study of host-parasite relationships is an integral part of the immunology of aquatic species, where the complexity of both organisms has to be overlayed with the lifecycle stages of the parasite and immunological status of the host. A deep understanding of how the parasite survives in its host and how they display molecular mechanisms to face the immune system can be applied for novel parasite control strategies. This review highlights current knowledge about salmon and sea louse, two key aquatic animals for aquaculture research worldwide. With the aim to catch the complexity of the salmon-louse interactions, molecular information gleaned through genomic studies are presented. The host recognition system and the chemosensory receptors found in sea lice reveal complex molecular components, that in turn, can be disrupted through specific molecules such as non-coding RNAs. 1. Introduction worldwide the most studied sea lice species are Lepeophtheirus salmonis and Caligus rogercresseyi [8–10]. Annually the salmon industry presents Host-parasite interactions are a complex relationship where one estimated losses of US $ 480 million, representing between 4 and 10% organism benefits the other and often where there is a negative impact of production costs [10].

The study of the Portuguese marine ichthyofauna has a long historical tradition, rooted back in the 18th Century. Here we present an annotated checklist of the marine fishes from Portuguese waters, including the area encompassed by the proposed extension of the Portuguese continental shelf and the Economic Exclusive Zone (EEZ). The list is based on historical literature records and taxon occurrence data obtained from natural history collections, together with new revisions and occurrences.

DOI: 10.3856/vol37-issue3-fulltext-21 Short Communication Note on the fisheries and biology of the golden crab (Chaceon fenneri) off the northern coast of Brazil Tiago Barros Carvalho1, Ronaldo Ruy de Oliveira Filho1 & Tito Monteiro da Cruz Lotufo1 1Laboratório de Ecologia Animal, Instituto de Ciências do Mar (LABOMAR) Universidade Federal do Ceará, Av. Abolição 3207, CEP 60165-081, Fortaleza, CE, Brazil ABSTRACT. The occurrence of golden crabs (Chaceon fenneri) off the northern coast of Brazil was first re- ported in 2001. Since then, a few companies and boats have exploited this resource. In the state of Ceará, one company has been fishing for these crabs with a single boat since 2003. The production and fishing effort of this company indicated a decrease in the number of trips and total catches per year. Data collected on one trip in 2006 showed that the CPUE was highest at over 650 m depth. As registered for other geryonid crabs, C. fenneri was segregated by sex along the northern slope of Brazil. Male crabs were significantly larger than fe- males, presenting an isometric relationship between carapace width and length and an allometric relationship between carapace width and body weight. Keywords: biology, fishery, Chaceon fenneri, golden crab, Geryonidae, Brazil. Nota sobre la biología y la pesca del cangrejo dorado (Chaceon fenneri) frente a la costa norte de Brasil RESUMEN.

Ruiz Legacy Program Abstract: SSpecies introductions have increased dramatically in number, rate, and magnitude of impact in recent decades. In marine systems, invertebrates are the largest and most diverse component of coastal invasions throughout the world. Ascidians are conspicuous and well-studied members of this group, however, much of what is known about their invasion history is limited to particular species or locations. Here, we provide a large-scale assessment of invasions, using an extensive literature review and standardized field surveys, to characterize the invasion dynamics of non-native ascidians in the continental United States and Alaska.
