Mapping the nearshore using a unique towfish by Herbert Vandermeulen ( )
4 editions published in 2011 in English and held by 79 WorldCat member libraries worldwide
The specifications and design of a towfish system are described for shallow water use. The towfish contains a color video camera, high frequency sidescan and positioning transponder. The towfish offers rapid 'transect' views of the bottom useful for describing habitat classes. The towfish is unique in that the video acts as a ground truth for the sidescan imagery in real time. The transponder on the towfish interacts with a transceiver mounted to the vessel hull to produce positional data to dGPS specifications (sub-meter precision). All video is georeferenced and stored as digital video clips in MapInfo GIS projects which also include towfish tracks and high frequency sidescan images (330 kHz, 30 m swath). The GIS projects can be used to generate habitat maps
An echosounder system ground-truthed by towfish data a method to map larger nearshore areas by Herbert Vandermeulen ( )
4 editions published in 2011 in English and held by 79 WorldCat member libraries worldwide
The specifications and design of an echosounder system are described for shallow water use. A BioSonics, Inc. DT-X digital echosounder with 210 and 430 kHz single beam transducers was custom fitted to a 22' research vessel with a unique transducer cage. The echosounder system can be run at 4 knots, offering rapid coverage of large areas of the bottom. Towfish transects (video and sidescan) are used to ground-truth the echosounder data, creating benthic habitat classes and maps. All positional data is collected at dGPS specifications (sub-meter precision)
Herring tagging in the vicinity of the Scotian Shelf and Gulf of St. Lawrence by the Maritimes Region, 1973-1982 by Wayne T Stobo ( Book )
4 editions published in 2009 in English and held by 66 WorldCat member libraries worldwide
Between 1973 and 1982 over 341,000 herring were tagged throughout the Bay of Fundy, Scotian Shelf, and southern Gulf of St Lawrence to examine stock structure and movements. Every major herring fishery in these areas was a subject of this decade-long tagging program, which attempted to distinguish the various known and suspected spawning components perceived at the time. Much of the data has never been examined, and for some areas, previous examinations utilized only early tag recoveries. Our examination suggests that current understandings of stock identities and migration patterns might warrant reconsideration or modification. This is especially true for juvenile herring stock components, but also for a number of adult components
At-sea catch analysis of inshore Scotia Shelf lobster fishery and 4VSW commercial index groundfish sentinel fishery by C. E. den Heyer ( )
3 editions published in 2010 in English and held by 59 WorldCat member libraries worldwide
On the Scotian Shelf, there are several inshore fisheries including lobster, rock crab, sea urchin, eel, groundfish, gaspereau, herring, sea scallops, smelt clams, worms and marine plants. The lobster fishery is the single most valuable fishery in Nova Scotia, and the majority of the fishery is prosecuted inshore, broadly distributed along the entire coastline. This intense fishery provides an opportunity to collect data on abundance and distribution of species that are captured by lobster traps along the entire coast of Nova Scotia and over extended time periods corresponding to the lobster seasons. In addition, this shallow trap fishery may allow nondestructive sampling of fish and invertebrates as the survival of discarded by-catch is expected to be high. For this study, researchers explored the use of commercial fishing vessels as sampling platforms for the inshore ecosystem. They assessed the potential of at-sea analysis of inshore commercial fisheries to (1) estimate by-catch of commercial and non-commercial species, (2) collect data on the distribution and abundance of commercial and non-commercial species, (3) collect morphometric data on individuals of commercial and non-commercial species and (4) monitor ecosystem metrics such as species diversity.--Document

Review of oil spill trajectory modelling in the presence of ice ( )
4 editions published in 2011 in English and held by 56 WorldCat member libraries worldwide
"This report addresses marine oil spill trajectory modelling with a focus on the Arctic environment. The primary goals are a synthesis of the state-of-knowledge on oil spill trajectory modelling and the identification of the key gaps in this knowledge as it applies to the Canadian Arctic. The review addresses all the components of a comprehensive oil spill trajectory model including 1) a blowout plume model to determine the distribution of oil in the water column for spills that occur at depth, 2) models for the physical environmental forcing (wind, air temperature, precipitation, ocean currents, sea ice and waves); and 3) an oil fate-and-effects model to address weathering, evaporation, ice-oil interactions, and other details of the oil's interplay with the environment. Novel challenges presented by the Arctic environment include the presence of sea ice, sparse observations of ocean currents and limited ability to monitor the spill's evolution."--Document
Atlantic halibut all-sizes tagging program summary report for 2006 to 2011 ( )
3 editions published in 2012 in English and held by 55 WorldCat member libraries worldwide
In 2006, Fisheries and Oceans Canada (DFO) and the Atlantic Halibut Council (AHC) began the Halibut All Sizes Tagging (HAST) program to estimate exploitation rate, describe the movement and distribution of halibut within the Scotian Shelf-southern Grand Banks management unit (NAFO Divs. 3NOPs4VWX5Zc), and estimate population size. Between 2006 and 2010, 2771 Atlantic Halibut caught during the DFO-Industry Halibut Survey were double tagged with t-bar anchor tags and released. Fishermen were compensated for the release of tagged halibut of commercial value (81 cm). Tag release information was recorded by fisheries observers and entered into DFO's Industry Surveys Database (ISDB). Fishermen were asked to return tags to DFO with information on the size, sex, date and location of recapture of tagged halibut. Each reported halibut was rewarded with $100 and an entry into a quarterly lottery for $1000. The tag recapture data is entered directly into the Halibut Tagging Database, an event-based Oracle database developed to house the release data extracted from the ISDB and the reports of recapture. Here the authors document the tagging program and database and identify areas for improvement.--Document
An overview of discards from the Canadian inshore scallop fishery in SFA 28 and SFA 29 West for 2002 to 2009 by J. A Sameoto ( )
3 editions published in 2012 in English and held by 54 WorldCat member libraries worldwide
This study characterizes discards by weight from the inshore scallop fishery in the Maritimes region, Canada, in Scallop Fishing Areas 28 and 29 West from 2002 to 2009. This study builds on a previous overview of discards conducted by Gavaris et al. (2010). The estimates reported are for total discards, discard rates, and discards as a percent of the total fishery catch. No adjustments to the discard estimates for post-release survival and unpermitted discarding were made.--Document

Early life history characteristics of the razor clam (Ensis Directus) and the moonsnails (Euspira spp.) with applications to fisheries and aquaculture by E Kenchington ( Book )
4 editions published in 1998 in English and held by 53 WorldCat member libraries worldwide
The purpose of this report is to provide new information on three species which show promise for aquaculture, based on attributes of species which are currently being cultured successfully. These three species are the razor clam, Ensis directus, and the moonsnails Euspira heros and E. triseriata. Part I documents periodic collection of razor clams from an intertidal bed in Nova Scotia for the purpose of determining growth rates and population size structure. It also describes an attempt to monitor growth of razor clams suspended from longlines on a commercial shellfish lease and attempts at harvesting subtidal beds using scuba gear and a hydraulic harvester. Part II describes observations and experimentation on the reproductive life cycle of moonsnails. Specifically, data were collected on food preference, mating behaviour, egg laying and settling behaviour of E. heros, intracapsular development under different temperature regimes in E. triseriata, post-metamorphosis growth and tentative identification of an unknown Canadian species, and observations of cannibalism. Implications for aquaculture and fisheries development are discussed
Description of three Ecopath with Ecosim ecosystem models developed for the Bay of Fundy, western Scotian Shelf and NAFO Division 4X by J. N Araújo ( )
3 editions published in 2011 in English and held by 53 WorldCat member libraries worldwide
The work described in this report is part of the Maritimes Region Ecosystem Research Initiative (ERI), a national program to enhance scientific research that was designed to contribute to progress on the ecosystem-based management (EBM) in Canada. This report documents the input data, and the development and balancing of three detailed mass balance trophic models (using the Ecopath with Ecosim (EwE) software) to represent the Bay of Fundy, western Scotian Shelf and the total area encompassing the first two systems, the 4X area, in the late 1990s (1995-2000)

Calibration of bottom trawl survey vessels : comparative fishing between the Alfred Needler and Teleost on the Scotian Shelf during the summer of 2005 by G. M Fowler ( Book )
4 editions published in 2009 in English and held by 45 WorldCat member libraries worldwide
Demersal surveys are conducted on Canada's Scotian Shelf (NAFO Divisions 4VWX) to provide ecological information on species inhabiting the continental shelf and slope waters off New Brunswick and Nova Scotia. From 1982 through 2003, the Scotian Shelf Summer (4VWX July) survey was conducted solely by one stern trawler, the Canadian Coast Guard Ship (CCGS) Alfred Needler. In August 2003, the Needler was seriously damaged by a fire while at sea. Repairs to engine and generator systems were lengthy, and the vessel was not ready to resume work until late August, 2004. Over the intervening period any standard surveys that had been the responsibility of the Needler was conducted by another DFO stern trawler, the CCGS Teleost. However, no data were available to quantify relative catchabilities of species between these two vessels. Thus the Teleost contribution to these surveys could not be used to gauge trends in abundance, or in any other time series context that required an assumption of equal catchabilities between vessels. Aside from the issue of how to interpret a single year of data provided by the Teleost, over the period that the Needler was undergoing repair and refit, it was recognized that the vessel might not be available on a consistent basis for future work. The Teleost was available as a replacement, but if used would also constitute a break in the time series, with no way to interpret trends in abundances or various other biological parameters from the Needler to the Teleost. To address this issue, an extensive series of comparative fishing experiments were conducted in 2004 and 2005, covering five standard groundfish surveys conducted annually in Atlantic Canada. The purpose of this document is to report on the results of one of these experiments-the Scotian Shelf Summer (4VWX July) survey conducted in 2005.--Document
Atlas of important habitat for key fish species of the Scotian Shelf, Canada by Tracy Horsman ( )
4 editions published in 2009 in English and held by 45 WorldCat member libraries worldwide
In 1997, Canada's Oceans Act was passed to provide a statutory framework for a national oceans management strategy based on the principles of sustainable development, integrated management and the precautionary approach. As part of this strategy, members of the Stakeholder Advisory Council for the Eastern Scotian Shelf Integrated Management (ESSIM) area developed a set of objectives under their identified goal for "Healthy Ecosystems." The species-based conservation objectives are to ensure that key species are not disturbed by human activity to the point of not being able to fulfill their role within the ecosystem. This atlas was prepared to provide contemporary regional information on the areas of importance during the summer for key species on the Scotian Shelf, Canada.--Document
