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 56 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( )
2 editions published in 2011 in English and held by 53 WorldCat member libraries worldwide
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. Chemical analyses (strontium concentrations) of the otoliths revealed that all specimens migrated from freshwater to the estuary or the sea. Time spent in the estuary, which is a mix of fresh and sea water, varied among individuals as did the time spent in full salinity sea water. Growth interpreted as "sea age" based on the scales often turned out to be estuarine growth based on the chemical analyses. There was no evidence that any of the specimens returned to fresh water to spawn or overwinter. This suggests that once out of the river the rainbow trout take up residency in the estuary or open ocean often for several years
Pour un nouveau cadre scientifique écosystémique en faveur d'une gestion intégrée ( )

Diet of cormorants, mergansers, and kingfishers in northeastern North America by David Kenneth Cairns( Book )
1 edition published in 1998 in English and held by 50 WorldCat member libraries worldwide
Reviews the literature on the diets of piscivorous birds in the Atlantic Provinces, eastern Quebec, and the Atlantic New England states. The review is based on published and unpublished dietary investigations on double-crested (Phalacrocorax auritus) and great (P. carbo) cormorants, common (Mergus merganser), red-breasted (M. serrator) and hooded (Lophodytes cucullatus) mergansers, and belted kingfishers (Ceryle alcyon), which are conspicuous members of riparian and estuarine ecosystems in the areas studied and are often at the centre of controversy regarding impact of predators on fish stocks. Diet compositions from individual studies are tabulated to the lowest taxonomic unit, and another table summarizes diet composition by region and prey group. Biases and gaps in the data are noted and prey selectivity among the birds is discussed

Annotated bibliography of demersal fish feeding with emphasis on selected studies from the Scotian Shelf and Grand Banks of the northwestern Atlantic by David Alan Methven( Book )
3 editions published in 1999 in English and held by 47 WorldCat member libraries worldwide
Summarizes 89 papers from the primary and secondary scientific literature that describe the diet and feeding ecology of demersal fish that occur on the Grand Banks, Scotian Shelf, and nearby waters. The following information, if available, is recorded for each study: purpose, predator, predator size, dominant prey, prey size, location and time of study, how prey were quantified, number of predator stomachs examined, depth, bottom type, and calorific content of prey. Text describing the contribution of the dominant prey of each predator is also included and is summarized with respect to sources of variation known to influence prey selection. The results are combined to gain an overview of the diet and feeding ecology of several of the best studied, most common, and commercially important species (gadids, pleuronectids, redfish, wolf-fish, and eelpout). Papers are arranged alphabetically by author

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

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)

Identifying research needs in support of regulatory aspects of the aquaculture framework agreement by Paul D Keizer( Book )
2 editions published in 2007 in English and held by 42 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."--Document
Temperature, salinity and sigma-t along the standard Flemish Cap transect by Eugene B Colbourne( Book )
2 editions published in 1996 in English and held by 41 WorldCat member libraries worldwide
Presents a review of the spatial and temporal distribution of the historical oceanographic data set on the Grand Banks of Newfoundland and on Flemish Cap along the standard transect adopted by the International Commission for the Northwest Atlantic Fisheries (47 degrees north latitude). Includes a brief descriptive analysis of various indices describing the temperature field along the transect and a discussion of the 1951-95 time series of the cross-sectional area of the cold intermediate layer. Annual time series of temperature, salinity, and density (sigma-t) are presented for the Avalon Channel, central Grand Bank, shelf edge, Flemish Pass, Flemish Cap, and Atlantic Ocean continental slope areas along the transect, based on all data available from 1931 to 1995. In addition, the monthly averaged vertical cross-sections for 1931-95 are presented, followed by monthly transects by year
