Salmon farms destroying wild salmon populations in Canada, Europe: study ALISON AULD . Canadian Press NewsWire . Toronto: Feb 11, 2008. Abstract (Summary) The authors, including the late Halifax biologist Ransom Myers, claim the study is the first of its kind to take an international view of stock sizes in countries that have significant salmon aquaculture industries. The paper didn't look to the causes of the declines, which have been discussed in a series of studies over the last decade that have linked disease, interbreeding of escaped salmon and lice from farmed fish with reductions. Full Text (618 words) Copyright Canadian Press Feb 11, 2008 HALIFAX _ Salmon farming operations have reduced wild salmon populations by up to 70 per cent in several areas around the world and are threatening the future of the endangered stocks, according a new scientific study. The research by two Canadian marine biologists showed dramatic declines in the abundance of wild salmon populations whose migration takes them past salmon farms in Canada, Ireland and Scotland. ``Our estimates are that they reduced the survival of wild populations by more than half,'' Jennifer Ford, lead author of the study published Monday in the Public Library of Science journal, said in Halifax. ``Less than half of the juvenile salmon from those populations that would have survived to come back and reproduce actually come back because they're killed by some mechanism that has to do with salmon farming.'' The authors, including the late Halifax biologist Ransom Myers, claim the study is the first of its kind to take an international view of stock sizes in countries that have significant salmon aquaculture industries.

    Identification guide to the deep–sea cartilaginous fishes of the Southeastern Atlantic Ocean FAO. 2015. 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.

INFORMATION TO USERS This manuscript has been reproduced from the microfilm master. UMI films the text directly from the original or copy submitted. Thus, some thesis and dissertation copies are in typewriter face, while others may be from any type of computer printer. The quality of this reproduction is dependent upon the quality of the copy submitted. Broken or indistinct print, colored or poor quality illustrations and photographs, print bleedthrough, substandard margins, and improper alignment can adversely affect reproduction. In the unlikely event that the author did not send UMI a complete manuscript and there are missing pages, these will be noted.
