Population Connectivity of Peltorhamphus Novaezeelandiae Between the Neighbouring Otago and Southland Regions of New Zealand Population connectivity of Peltorhamphus novaezeelandiae between the neighbouring Otago and Southland regions of New Zealand. Patricia Mary Mockett A thesis submitted for the degree of Master of Science at the University of Otago, Dunedin, New Zealand. July 2013 ii Abstract Connectivity among subpopulations of organisms is a primary focus in marine ecology and this knowledge is particularly imperative to the development of regulations in the management of fisheries (Cowen et al., 2007). The structure of local populations can be identified using intrinsic markers such as morphological and life history characteristics, as well as genetic markers (Bailey, 1997, Begg and Waldman, 1999). Genetic techniques are limited in that they cannot detect low levels of exchange (Thresher, 1999). Life history, morphological and meristic characteristics have been regularly employed to identify differentiation between local populations and in order to create a robust study it is reccomended that a combination of traits be examined (Begg and Waldman, 1999). The objective of the present study is to determine the level of connectivity among subpopulations of the flatfish species Peltorhamphus novaezeelandiae in the neighbouring Otago and Southland regions of New Zealand. I endeavoured to determine whether these fish form a single panmictic population over this geographical landscape or, are in fact segregated into discrete sub- populations. Flatfish as a group are an important component in New Zealand’s annual commercial catch particularly in the Otago and Southland regions, yet there is little biological information available on each species including Peltorhamphus novaezeelandiae. Fish from each region were sampled by otter trawl and morphological, stable isotope, stomach content and age determination analyses were conducted. As a result of these analyses I concluded that Peltorhamphus novaezeelandiae exhibit a complex population structure within the Otago and Southland regions of New Zealand. These subpopulations experience connectivity whether it be via the dispersal and recruitment of eggs, larvae or juveniles or through the migration of adults. Subpopulations are subject to enough separation over spatial and temporal scales to enable and maintain significant differences in life history characteristics. It is evident that the population structure of P.novaezeelandiae occurs at smaller spatial scales than is currently recognised by the Quota Management System and it is hoped that the knowledge gained through the completion of this study enables more informed management decisions and the sustainability of this important fish stock. iii Acknowledgements Firstly, I would like to thank my supervisor Steve Wing for the extensive knowledge you have imparted on me during the development and completion of my thesis and to the University of Otago’s Marine Science Department which has given me the opportunity to meet some amazing people of whom I hope to never lose contact with. Early on in my thesis work I had the opportunity to travel to the National Fish Collection unit at Te Papa museum in Wellington where I was fortunate to meet collection manager, Andrew Stewart and visiting flatfish researcher from NOAA, Thomas Monroe. I would like to extend my sincere thanks to Tom as his knowledge and training in Peltorhamphus identification was invaluable. Your enthusiasm for the amazing world of flatfishes was very contagious. A special thanks to all staff at the Portobello Marine Lab, it was nice to see your smiling faces when I was getting frustrated with my work! To the Marine Studies Centre staff, I am grateful to have had the opportunity to work with you all and to be able to pursue my passion for all marine creatures while working in the aquarium. I even discovered that I enjoyed teaching much to my amazement. A big thank you to Ant Smith of the F.V Aurora, who went to immense trouble to collect fish required for this study, all of which were donated to me. And finally, to all of my family and friends who had lost hope that they would ever see the day that I finally submitted this thesis, my parents Debbie and Bruce Mockett, my In-laws Viv and Colin Adam. Thank you for your never ending support, there were times when I wanted to quit but you kept me going. To my dad Bruce, thank you for all your help in the field and the never ending discussions and requests for progress reports. To my loving husband Scott Adam, your ongoing enthusiasm for all marine creatures is my greatest encouragement of all and my involvement in your varied work history in the commercial fishing sector has enabled me to have some incredible experiences that I wouldn’t have had the opportunity to otherwise. Thank you for all of the hours you spent assisting me in fish collections, transporting animals back to the lab and frequent visits out to Portobello to feed them. This is just the beginning of many more adventures together. iv Table of contents Abstract ......................................................................................................................................... iii Acknowledgements ....................................................................................................................... iiv Table of contents............................................................................................................................. v List of figures ............................................................................................................................... ixx List of tables ................................................................................................................................... xi Chapter 1: GENERAL INTRODUCTION 1 1.1 Marine populations ............................................................................................................ 1 1.2 Population connectivity ..................................................................................................... 1 1.3 Identification of fish stocks ............................................................................................... 2 1.4 Techniques for identifying population connectivity and structure .................................... 3 1.5 Flatfish biology .................................................................................................................. 4 1.6 Peltorhamphus species ....................................................................................................... 5 1.7 Commercial interest and management .............................................................................. 5 1.8 Study Sites ........................................................................................................................ 8 1.8.1 Otago .......................................................................................................................... 8 1.8.2 Southland .................................................................................................................... 9 1.9 Objectives ....................................................................................................................... 10 Chapter 2: AGE AND GROWTH .............................................................................................. 11 2.1 Introduction ................................................................................................................... 11 2.1.1 The importance of age and growth in fisheries management................................... 11 2.1.2 Age determination using otoliths ............................................................................. 12 2.1.3 Forms of aging error ................................................................................................. 13 2.2 Objectives ....................................................................................................................... 15 2.3 Materials and Methods ................................................................................................. 16 2.3.1 Sample collection ..................................................................................................... 16 2.3.2 Otolith preparation for aging .................................................................................... 18 v 2.3.3 Age estimation...................................................................................................... 1919 2.3.4 Freezing Effects.................................................................................................... 1919 2.4 Data Analysis ............................................................................................................. 2222 2.4.1 Von Bertalanffy growth function 23 2.4.2 Growth curve comparison ........................................................................................ 23 2.5 Results ............................................................................................................................. 23 2.5.1 Length frequency and sex ratio ................................................................................ 23 2.5.2 Analysis of precision between readers ..................................................................... 26 2.5.3 Von Bertalanffy growth model ................................................................................ 27 2.6 Discussion ....................................................................................................................... 31 2.6.1 Aging precision between readers ............................................................................

The ECNASAP Pilot Project consists of inshore and offshore case studies, and is a cooperative effort among several U.S. and Canadian agencies. Digital map and data products are being developed in the Offshore Case Study for groundfish, seabirds, temperature, salinity, and sediments. This report summarizes the initial results for the groundfish component. About Partitioning the Total Mortality of Atlantic Cod Stocks Project In 1995, Canada's Department of Fisheries and Oceans (DFO) initiated a series of research projects to address high priority issues for the Atlantic and Pacific coasts. The Cod Mortality Project is a component of this effort; its objective is to assess the main causes for the decline of cod resources since the mid-1980s. A subproject is to examine long-term changes in groundfish assemblages on a biogeographic scale, and to determine whether or not these changes coincided with changes in ocean climate.

  • Early Stages of Fishes in the Western North Atlantic Ocean Volume
    ISBN 0-9689167-4-x Early Stages of Fishes in the Western North Atlantic Ocean (Davis Strait, Southern Greenland and Flemish Cap to Cape Hatteras) Volume One Acipenseriformes through Syngnathiformes Michael P. Fahay ii Early Stages of Fishes in the Western North Atlantic Ocean iii Dedication This monograph is dedicated to those highly skilled larval fish illustrators whose talents and efforts have greatly facilitated the study of fish ontogeny. The works of many of those fine illustrators grace these pages. iv Early Stages of Fishes in the Western North Atlantic Ocean v Preface The contents of this monograph are a revision and update of an earlier atlas describing the eggs and larvae of western Atlantic marine fishes occurring between the Scotian Shelf and Cape Hatteras, North Carolina (Fahay, 1983). The three-fold increase in the total num- ber of species covered in the current compilation is the result of both a larger study area and a recent increase in published ontogenetic studies of fishes by many authors and students of the morphology of early stages of marine fishes. It is a tribute to the efforts of those authors that the ontogeny of greater than 70% of species known from the western North Atlantic Ocean is now well described. Michael Fahay 241 Sabino Road West Bath, Maine 04530 U.S.A. vi Acknowledgements I greatly appreciate the help provided by a number of very knowledgeable friends and colleagues dur- ing the preparation of this monograph. Jon Hare undertook a painstakingly critical review of the entire monograph, corrected omissions, inconsistencies, and errors of fact, and made suggestions which markedly improved its organization and presentation.

The samples were collected with bongo nets and a Multi Plankton Sampler (MPS), both in summer and winter 2002. A total of 352 flatfishes larvae were collected in summer and 343 in winter, representing three families and a total of 13 taxa: Paralichthyidae ( Citharichthys cornutus, C. spilopterus, Citharichthys sp ., Cyclopsetta chittendeni, Syacium spp ., Etropus spp . and Paralichthys spp .), Bothidae ( Bothus ocellatus and Monolene antillarum ) and Cynoglossidae ( Symphurus trewavasae, S. jenynsi, S. plagusia and S. ginsburgi ). The most abundant taxa were Etropus spp ., Syacium spp . and Bothus ocellatus . Etropus spp . occurred mainly as far out as the 200 m isobath and Syacium spp . from 100 m. B. ocellatus was present mainly in the oceanic zone between Ubatuba and Rio de Janeiro as from the 200 m isobath. The greatest average densities of these species occurred in the strata from 0 to 20 m depth in summer and between 20 and 40 m in winter. RESUMO O objetivo deste estudo foi descrever a composição, abundância, densidade, distribuição horizontal e vertical das larvas de Pleuronectiformes ao longo da plataforma continental Sudeste brasileira.

  • Complete Mitochondrial Genome Sequences of Three Rhombosoleid
    Wang et al. Zoological Studies 2014, 53:80 http://www.zoologicalstudies.com/content/53/1/80 RESEARCH Open Access Complete mitochondrial genome sequences of three rhombosoleid fishes and comparative analyses with other flatfishes (Pleuronectiformes) Shu-Ying Wang, Wei Shi, Xian-Guang Miao and Xiao-Yu Kong* Abstract Background: Peltorhamphus novaezeelandiae, Colistium nudipinnis, and Pelotretis flavilatus belong to the family Rhombosoleidae of Pleuronectiformes. Their high phenotypic similarity has provoked great differences in the number and nomenclature of the taxa that depend primarily on morphological features. These facts have made it necessary to develop molecular markers for taxonomy and phylogenetic studies. In this study, the complete mitogenomes (mtDNA) of the three rhombosoleid fishes were determined for the comparative studies and potential development of molecular markers in the future. Results: The lengths of the complete mitogenome of the three flatfishes are 16,889, 16,588, and 16,937 bp in the order mentioned above. The difference of lengths mainly results from the presence of tandem repeats at the 3′-end with variations of motif length and copy number in the control regions (CR). The gene content and arrangement is identical to that of the typical teleostean mtDNA. Two large intergenic spacers of 28 and 18 bp were found in P. flavilatus mtDNA. The genes are highly conserved except for the sizes of ND1 (which is 28 bp shorter than the two others), ND5 (13 bp longer), and tRNAGlu (5 bp longer) in P. flavilatus mtDNA. The symbolic structures of the CRs are observed as in other fishes, including ETAS, CSB-F, E, D, C, B, A, G-BOX, pyrimidine tract, and CSB2, 3.
