  • 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 term Elasmobranchs or chondrichthyans refers to the The great majority of the commercially important species of group of marine organisms with a skeleton made of cartilage. chondrichthyans are elasmobranchs. The latter are named They include sharks, skates, rays and chimaeras.

In total, there are about 869+ extant species group of bony fishes in the characteristics like cartilaginous of elasmobranchs, with about 400+ of those being sharks skeleton, absence of swim bladders and presence of five and the rest skates and rays. Taxonomy is also perhaps to seven pairs of naked gill slits that are not covered by an infamously known for its constant, yet essential, revisions operculum. The chondrichthyans which are placed in Class of the relationships and identity of different organisms. Elasmobranchii are grouped into two main subdivisions Classification of elasmobranchs certainly does not evade this Holocephalii (Chimaeras or ratfishes and elephant fishes) process, and species are sometimes lumped in with other with three families and approximately 37 species inhabiting species, or renamed, or assigned to different families and deep cool waters; and the Elasmobranchii, which is a large, other taxonomic groupings. It is certain, however, that such diverse group (sharks, skates and rays) with representatives revisions will clarify our view of the taxonomy and phylogeny in all types of environments, from fresh waters to the bottom (evolutionary relationships) of elasmobranchs, leading to a of marine trenches and from polar regions to warm tropical better understanding of how these creatures evolved.

    A5 By-catch Species APPENDIX 5: BY-CATCH SPECIES A.5 By-catch species By-catch is the unintentional/incidental capture of non-target species during fishing operations. Different types of fisheries have different types and levels of by-catch, depending on the gear used, the time, area and depth fished, etc. Article IV of the Convention states: "the Commission shall be responsible for the study of the population of tuna and tuna-like fishes (the Scombriformes with the exception of Trichiuridae and Gempylidae and the genus Scomber) and such other species of fishes exploited in tuna fishing in the Convention area as are not under investigation by another international fishery organization". The following is a list of by-catch species recorded as being ever caught by any major tuna fishery in the Atlantic/Mediterranean. Note that the lists are qualitative and are not indicative of quantity or mortality. Thus, the presence of a species in the lists does not imply that it is caught in significant quantities, or that individuals that are caught necessarily die.

(IPMA), Avenida 5 de Outubro s/n, 8700-305 Olhão, Portugal 2 Centro de Ciências do Mar (CCMAR), Universidade do Algarve, Campus de Gambelas FCT Ed.7, 8005-170 Faro, Portugal Received 6 February 2012; Accepted 24 September 2012 Abstract – Hooking (or “at-haulback”) fishing mortality was analysed in elasmobranchs captured by Portuguese long- liners targeting swordfish in the Atlantic Ocean. Information was collected by on-board fishery observers who moni- tored 834 longline fishing sets between August 2008 and December 2011, and recorded information on 36 067 elasmo- branch specimens from 21 different taxa. The hooking mortality proportions were species-specific, with some species having relatively high percentages of live specimens at time of haulback (e.g., blue shark, crocodile shark, pelagic stingray, manta, devil and eagle rays), while others had higher percentages of dead specimens (e.g., smooth hammer- head, silky shark, bigeye thresher). For the most captured species (Prionace glauca, Pseudocarcharias kamoharai, Isurus oxyrinchus and Alopias superciliosus), logistic generalized linear models (GLMs) were carried out to compare the mortality rates between sexes, specimen sizes and the regions of operation of the fleet. The sex-specific proportions of hooking mortality were significantly different for blue and crocodile sharks, with the males of both species having higher proportions of hooking mortality than the females.

Identification guide to the deep–sea cartilaginous fishes of the Southeastern Atlantic Ocean. FishFinder Programme, by Ebert, D.A. and Mostarda, E., Rome, Italy. Supervision: Merete Tandstad, Jessica Sanders (FAO, Rome) Technical editor: Edoardo Mostarda (FAO, Rome) Colour illustrations, cover and graphic design: Emanuela D’Antoni (FAO, Rome) This guide was prepared under the “FAO Deep–sea Fisheries Programme” thanks to a generous funding from the Government of Norway (Support to the implementation of the International Guidelines on the Management of Deep-Sea Fisheries in the High Seas project) for the purpose of assisting states, institutions, the fishing industry and RFMO/As in the implementation of FAO International Guidelines for the Management of Deep-sea Fisheries in the High Seas. It was developed in close collaboration with the FishFinder Programme of the Marine and Inland Fisheries Branch, Fisheries Department, Food and Agriculture Organization of the United Nations (FAO). The present guide covers the deep–sea Southeastern Atlantic Ocean and that portion of Southwestern Indian Ocean from 18°42’E to 30°00’E (FAO Fishing Area 47). It includes a selection of cartilaginous fish species of major, moderate and minor importance to fisheries as well as those of doubtful or potential use to fisheries. It also covers those little known species that may be of research, educational, and ecological importance. In this region, the deep–sea chondrichthyan fauna is currently represented by 50 shark, 20 batoid and 8 chimaera species. This guide includes full species accounts for 37 shark, 9 batoid and 4 chimaera species selected as being the more difficult to identify and/or commonly caught.
