An atlas and classification of aquatic habitat on the east coast of Canada, with an evaluation of usage by the American eel ( )
4 editions published in 2012 in English and held by 84 WorldCat member libraries worldwide
This atlas proposes a new classification scheme for the coastal waters of eastern North America, that is based on cartographic data that are available for the entire region. This work is prompted by the conservation needs of the American eel (Anguilla rostrata). This document implements the classification scheme for eastern Canadian waters from the Strait of Belle Isle to the United States border, and evaluates the relation between classification categories and American eel distribution as indicated by commercial and research fishing records.--Document."
Identifying research needs in support of regulatory aspects of the aquaculture framework agreement by Paul D Keizer ( Book )
4 editions published in 2007 in English and held by 67 WorldCat member libraries worldwide
A framework is presented for the identification of priorities for research in support of the regulatory aspects of the Aquaculture Framework Agreement that is under development by the Canadian Council of Fisheries and Aquaculture Ministers. The proposed framework is based on the risk analysis of the hazards associated with aquaculture. The analysis is limited to the risks as defined by published information on the severity and probability of occurrence of undesirable outcomes. Recent comprehensive peer reviews of the scientific literature are used as the knowledge base. The analysis can be readily updated when additional knowledge is available. The framework is generally applicable and could be used to include the socioeconomic and political risks in the analysis
Discrimination of the endangered Atlantic whitefish (Coregonus huntsmani Scott, 1987) larvae and juveniles by Daniel J Hasselman ( )
3 editions published in 2012 in English and held by 54 WorldCat member libraries worldwide
Atlantic Whitefish (Coregonus huntsmani) are an endangered species endemic to Nova Scotia, Canada. Several actions identified in the Atlantic Whitefish recovery strategy require accurate identification of the species early life history stages. While criteria exists for the discrimination of adult specimens, no such criteria is available for larvae or juveniles. Using specimens obtained from the captive mating of wild caught adults, and those made available to this study, the authors conduct discriminant function analyses on phenetic characters, and incorporate species specific pigmentation patterns to develop discrimination criteria for early life history stage Atlantic Whitefish, Lake Whitefish (C. clupeaformis), and Cisco (C. artedii).--Document
Using otolith Sr concentrations to monitor marine migrations in rainbow trout (Oncorhynchus mykiss) from Shoal Harbour, Newfoundland by G Veinott ( )
3 editions published in 2011 in English and held by 53 WorldCat member libraries worldwide
The Shoal Harbour River rainbow trout population supports a local sport fishery. However, nothing is known about their marine migrations or the extent to which rainbow trout use the estuarine environment. The purpose of this study therefore, was to use Sr in the otoliths of rainbow trout from Shoal Harbour to study the frequency and duration of their marine migrations. Twelve rainbow trout were provided to DFO from anglers in the Shoal Harbour area. Eleven of the 12 specimens were female and most were sexually immature. Ages ranged from 3 to 7 years with river ages of 1-4 years and sea ages of 1-4 years. Only the oldest specimen had a spawning mark on its scales.--Document

Metabolic and cellular responses of Atlantic salmon (Salmo salar) gill to intermittent hypoxia ( )
2 editions published in 2012 in English and held by 47 WorldCat member libraries worldwide
Sea cage Atlantic salmon farming in Newfoundland is expanding rapidly, with notable increases in activity on the south coast including Fortune and Placentia bays. In marine cages, levels of dissolved oxygen (DO) are often unpredictable, with common occurrences of intermittent hypoxic conditions. Such changes may affect the physiology of the fish, as adequate DO is essential to fish health and successful production. Juvenile Atlantic salmon were exposed to intermittent hypoxic conditions over a 47 day period. Fish were killed 18 -36 hours post exposure and gills excised. Gill tissue from hypoxic and normoxic exposed fish were analyzed for enzyme activity, protein concentrations, and analyzed histologically for abnormalities and eosinophilic granulocyte (EGC) distribution and quantification.--Document

Effect of gear type and initial stocking density on production of meats and large whole scallops (Placopecten magellanicus) using suspension culture in Newfoundland by R. W Penney ( Book )
2 editions published in 1995 in English and held by 45 WorldCat member libraries worldwide
This paper investigates the production of large, whole giant sea scallops and meats in suspension culture using pearl nets and lantern nets, and describes the effect of varying initial stocking density on growth and survival during final growout to market size. The investigators reared the scallops (Placopecten magellanicus) at five different stocking densities at a shellfish farm at Notre Dame Bay, Newfoundland. Significant relationships are reported among mean shell height, total weight, meat weight, and stocking density and gear type. The report discusses the practical implications of the growth and survival results for commercial farm practices related to stocking densities, gear type selection, stock thinning, and labor costs, for the production of large, whole scallops, meats, and meat with roe products
Evaluation of habitat improvement and restoration initiatives for salmonids in Newfoundland, Canada by D. A Scruton ( Book )
2 editions published in 1997 in English and held by 45 WorldCat member libraries worldwide
This report provides a overview of these evaluations, as selected case studies including projects involving restoration of habitat degraded historic forest harvesting (Joe Farrell's Brook and Pamehac Brook), removal of a natural migration barrier (Dead Wolf Brook), and the addition of spawning gravel to increase juvenile salmonid production (Northeast Placentia River).--Abstract
A survey of benthic macroinvertebrates in rivers in Placentia Bay, Newfoundland by M. F O'Connell ( Book )
2 editions published in 1996 in English and held by 45 WorldCat member libraries worldwide
Presents results of a study of benthic macroinvertebrates and their diversity, conducted in six rivers in Placentia Bay as part of an overall environmental assessment prompted by industrialisation in the bay. Investigators sampled using a Suber sampler at two or three stations in each river, taking five or ten replicate samples at each station. They identified organisms to the level of genus in most cases and some to species, and examined community diversity using the Shannon-Wiener index. The information presented can be regarded as baseline data for four watersheds (Northeast River, North Harbour River, Bay De L'Eau River, Rushoon River) and as indicative of conditions prevailing at the time for the watersheds in the immediate vicinity of the Come By Chance oil refinery (Come By Chance River) and the Long Harbour phosphorus plant (Bottom Brook)
Effect of injection of lipopolysaccharides from Aeromonas salmonicida on some aspects of cod (Gadus morhua) immunity and appetite hormones ( )
3 editions published in 2010 in English and held by 43 WorldCat member libraries worldwide
Atlantic cod is a species of considerable economic importance in the North Atlantic and in recent years experimental farming has been successfully carried out in Canada. In this context, studies on the interaction of feeding and the immune system of Atlantic cod are highly relevant. The authors investigated the effects of lipopolysaccharide (LPS) from Aeromonas salmonicida on the mRNA expression of the appetite regulating peptides ghrelin, neuropeptide Y (NPY) and cocaine and amphetamine-regulated transcript (CART) of Atlantic cod juveniles. In addition, they measured the effects of LPS on the fish cellular immune responses (respiratory burst, RB) of head kidney and whole blood leukocytes and stress responses in juvenile Atlantic cod (Gadus morhua L.).--Includes text from document
