Temporal variation of stream and intragravel water temperatures in an Atlantic salmon (Salmo salar) spawning area in Catamaran Brook (New Brunswick) by Daniel Caissie( Book )

2 editions published in 2003 in English and held by 52 WorldCat member libraries worldwide

The objective of this study was to characterize the stream & intragravel water temperatures within a salmon spawning area in Catamaran Brook, New Brunswick, from 1996 to 1998. A one-dimensional diffusion model is used to determine how well temporal patterns in intragravel water temperatures can be modelled. Results of measurements are presented & discussed with regard to daily patterns in water temperature, diurnal variations, monthly temperature patterns, and the relationship between temperature fluctuations & environmental events
The predation of zooplankton by the blue mussel (Mytilus edulis) and the clubbed tunicate (Styela clava)( Book )

3 editions published in 2007 in English and held by 37 WorldCat member libraries worldwide

This study was undertaken in response to industry concerns that tunicates may filter mussel larvae resulting in low recruitment of spat. The objective was to determine if Styela clava as well as adult mussels significantly reduce the number of mussel larvae by filter feeding. Other zooplankton taxa were also examined to better understand the filtering capabilities of the two species and their potential to affect recruitment of near shore marine communities.--Document
A third-generation direct-entry system for gathering biological data from fish by Clarence Bourque( Book )

2 editions published in 2005 in English and held by 37 WorldCat member libraries worldwide

The Department of Fisheries and Oceans scientific staff at the Gulf Fisheries Centre, in Moncton, New Brunswick measure 80,000 to 120,000 herring and gather detailed biological data from 6,000 to 10,000 of these each year as part of the annual stock assessment and evaluation process. These fish come from samples of the commercial fishery, at-sea surveys and other research projects carried out each year. To enhance efficiency and accuracy an automated online computerized data entry, coding and verification system was developed. This system was updated to a more user-friendly graphic user interface based system compatible with 16-bit computer and networking technology. The enhanced multimedia capabilities and faster hardware found in modern computers as well as network compatibility issues and security constraints commonly in place on Local Area Networks made it necessary to update the software to be compatible with the 32-bit Windows XP platform. The updated software uses multimedia prompting and warning messages to improve efficiency, reduce errors and user fatigue. New graphic user interface based software was developed to replace outdated MSDOS based programs used to manipulate and initialize the electronic fish measuring board hardware component which are no longer fully supported under modern platforms. This document provides an overview of the system's different facilities including main data-gathering functions and utilities developed along with the main software
The effect of sock spacing on the productivity of mussel on longline system( Book )

3 editions published in 2007 in English and held by 37 WorldCat member libraries worldwide

The objective of this study was to investigate the direct link between sock spacing and mussel productivity on four grow-out leases in Tracadie Bay, PEI by means of a controlled trial. A large-scale experiment was conducted in distinct leases of Tracadie Bay, PEI over a one-year production cycle. This report presents the study results.--Document
Quality assurance : quality control (QA/QC) program for the community aquatic monitoring program (CAMP) by M.-H Thériault( Book )

2 editions published in 2008 in English and held by 37 WorldCat member libraries worldwide

A quality assurance and quality control (QA/QC) program was carried out at six Community Aquatic Monitoring Program (CAMP) sites in July-August 2007 to determine the accuracy and the precision of faunal identification and abundance estimates provided by environmental nongovernmental organizations (ENGOs). ENGOs enumerated adults and young-of-the-year for each species, following CAMP protocols, but then retained the catch instead of releasing it live in order to be re-processed by Dept. of Fisheries and Oceans (DFO) biologists. Three to five of the six stations normally sampled within each site were examined. Species richness and total abundance for each species, by station and site, were compared between DFO biologists and ENGOs.--Document

2 editions published in 2008 in English and held by 37 WorldCat member libraries worldwide

This report details the results of efforts to remove algae and nutrient inputs from Lamèque Bay, a shallow temperate bay located in northeastern New Brunswick. Analyses of redox and sulphides are provided as well as evidence identifying the causes of improved oxygenation of sediments between 2001 and 2007.--Includes text from document
Avoidance by sand shrimp, Crangon septemspinosa, of sandy patches covered by hydrated lime (calcium hydroxide) deposits( Book )

3 editions published in 2011 in English and held by 35 WorldCat member libraries worldwide

Hydrated lime (Ca(OH)2, also called calcium hydroxide or slaked lime) is commonly used as a pesticide by the mussel (Mytilus edulis) and oyster (Crassostrea virginica) industries on Prince Edward Island (PEI). Hydrated lime is a caustic agent that greatly elevates pH when dissolved in water. Though it is unstable in seawater (it readily combines with dissolved carbon dioxide to form harmless limestone, CaCO3), the fact that relatively large amounts of it may be released into the environment in single locations within a bay (i.e., on aquaculture lease sites) raises concerns about its possible effects on other organisms in the environment. One such organism is the sand shrimp, Crangon septemspinosa, also known by the common name seven-spined bay shrimp. The possibility exists that hydrated lime may at least temporarily foul sand shrimp habitat by creating a carpet of deposits over sandy patches, if the hydrated lime release site is in or near shallow water. Yet there is no information on the reaction of sand shrimp to such deposits. The goal of this study was to assess in the laboratory whether sand shrimp avoid sandy areas with carpets of hydrated lime deposits.--Document

The Community Aquatic Monitoring Program (CAMP) for measuring marine environmental health in coastal waters of the southern Gulf of St. Lawrence : 2007 overview by J. W Weldon( Book )

4 editions published in 2009 in English and held by 9 WorldCat member libraries worldwide

In 2003, the Department of Fisheries and Oceans (DFO) Gulf Region initiated the development of a monitoring program called the Community Aquatic Monitoring Program (CAMP). One of the program goals was to help determine the ecological health of estuaries and coastal shorelines in the southern Gulf of St. Lawrence (sGSL). The primary goal of CAMP continues to provide an outreach program for DFO to interact with community environmental groups. The monitoring portion of CAMP is being used to test the hypothesis that a relationship exists between the health of an estuary or coastal shoreline and the diversity and abundance of finfish and crustacean species which inhabit the intertidal and near shore zone. CAMP expanded the number of locations from 4 in its 2003 pilot year (Theriault et al. 2006) to 24 throughout the Maritime Provinces of Nova Scotia (NS), New Brunswick (NB) and Prince Edward Island (PEI) in 2004. Baseline sites, meaning sites at which 6 stations were sampled by day-time beach seining once a month from May to September inclusive numbered 13 in 2004. In 2005, the number of locations totalled 22 of which 20 were considered as baseline (Weldon et al. 2007). In 2006, there were 22 locations participating and 18 were able to collect data for the five full months. In 2007, the number of baseline sites increased to 25, 24 of which maintained baseline status. NGOs in each watershed adhered to the same sampling methodology and related protocols as outlined in Weldon et al. (2005). All species of finfish, crab and shrimp collected were identified, separated into adults and young of the year, enumerated and released. Habitat was also characterized by collecting information such as water temperature, salinity, dissolved oxygen, % plant cover and algae cover and, once a year in September, collection of a substrate sample for measurement of grain size distribution, % moisture content and % organic content. Two water samples were collected at each station at all locations all 5 months then sent away for analysis of nutrient content. This report summarizes baseline physical and biological data for the estuaries sampled in 2007. This year more almost six hundred thousand (597295) animals were processed and 37 different species were identified. In order to test the hypothesis that these data reflect environmental quality, we are getting close to the several years of data required to detect temporal and spatial patterns that may exist
Preliminary index of essential habitats for certain marine species of importance in the eastern region of New Brunswick by J Therrien( Book )

5 editions published in 2000 in English and held by 8 WorldCat member libraries worldwide

This document presents a representative portrait of the information currently available on major marine resources in eastern New Brunswick in the form of data on 30 essential habitats of 31 marine species or groups of species. The descriptions are divided into three ecozones: Chaleur Bay, Shediac Valley, and the Northumberland Strait. The term "essential habitat" is used to characterize each species/habitat grouping representative of a vital habitat for a particular wildlife species. These areas are essential for various crucial stages in the species life cycle (such as spawning ground, feeding ground, or migration area) or they constitute a major area of concentration, particularly for mostly sedentary species such as mollusks. Fish concentration areas are generally not included, except for those associated with one particular life stage or a threatened species. The final section includes a brief analysis of the ecological and socio-economic characteristics of the habitats
Comparison of eastern oyster (Crassostrea virginica) and blue mussel (Mytilus edulis) filtration rates at low temperatures( Book )

3 editions published in 2008 in English and held by 7 WorldCat member libraries worldwide

The eastern oyster, Crassostrea virginica, is highly tolerant of extremes in ambient temperatures. For suspension-feeding bivalves, low temperature decreases food intake by acting on the animals' physiological rates, and also by changing the water's physical properties, particularly viscosity. In this study, the researchers collected C. virginica in the Gulf of St. Lawrence (GSL) and estimated its filtration rate in cold waters. The blue mussel Mytilus edulis (L.) was used during the present study as a benchmark for comparison because it is ubiquitous in the GSL. The comparison of C. virginica and M. edulis may provide practical information for the management of shellfish closures in the GSL. Harmful algal blooms (HABs), consisting of the domoic-acid-producing diatom Pseudonitzschia multiseries, have historically occurred in autumn or spring, when water temperature is low.--Includes text from document
Off bottom oyster (Crassostrea virginica Gmelin) culture in Prince Edward Island : an evaluation of seed sources and stocking density by Luc A Comeau( Book )

4 editions published in 2012 in English and held by 7 WorldCat member libraries worldwide

The trend in the oyster aquaculture industry for Eastern Oyster, Crassostrea virginica, in Prince Edward Island (PEI) is towards off bottom culture in at least a portion of the oyster aquaculture production cycle and the use of bags mounted on racks has gained favor among oyster aquaculturists. Growth rate, survival and shell shape are generally considered important traits to determine the quality and grade of cultivated oysters. The purpose of this study was to examine the effects of seed source and stocking density on the productivity of oysters cultivated off the bottom. Specfically, there were three objectives. The first was to compare the growth and mortality rates of oysters obtained from five seed collection areas on PEI and maintained in one growing area. The second was to compare growth and mortality rates of oysters demonstrating superior growth traits from four of the five seed collection areas on PEI. The third was to examine the effects of stocking density on oyster growth, mortality and shell shape (grade).--Includes text from document
The Community Aquatic Monitoring Program (CAMP) for measuring marine environmental health in coastal waters of the southern Gulf of St. Lawrence 2006 overview by J. W Weldon( Book )

3 editions published in 2008 in English and held by 5 WorldCat member libraries worldwide

In 2003, the Department of Fisheries and Oceans (DFO) Gulf Region developed a monitoring program called the Community Aquatic Monitoring Program (CAMP) to help determine the ecological health of estuaries and coastal shorelines in the southern Gulf of St. Lawrence (sGSL). The primary goal of CAMP continues to provide an outreach program for DFO to interact with community environmental groups. The monitoring aspect developed from this partnership was to test the hypothesis that a relationship exists between the health of an estuary or coastal shoreline and the diversity and abundance of finfish and crustacean species which inhabit the littoral or near shore zone. CAMP expanded the number of locations from 4 in its 2003 pilot year (Theriault et al. 2006) to 24 throughout the Maritime Provinces of Nova Scotia (NS), New Brunswick (NB) and Prince Edward Island (PEI) in 2004. Baseline sites, meaning sites at which 6 stations were sampled by day-time beach seining once a month from May to September inclusive numbered 15 in 2004. In 2005, the number of locations totalled 22 of which 20 were considered as baseline (Weldon et al. 2007). In 2006, there were 22 locations participating and 18 were able to collect data for the five full months. Each community environmental group adhered to the same sampling methodology and related protocols as outlined in Weldon et al. (2005). All species of finfish, crabs and shrimp collected were identified, separated into young of the year and adults, enumerated and then released. Habitat was also characterized by collecting information such as water temperature, salinity, dissolved oxygen, % plant cover and algae cover and, once a year in September, collection of a substrate sample for measurement of grain size distribution, % moisture content and % organic content. Two water samples were collected at each location and analysed for nutrient content. This report summarizes baseline physical and biological data for the estuaries sampled in 2006. This year slightly less than four hundred thousand animals were processed and 35 different species were identified. In order to test the hypothesis that these data reflect environmental quality, several years of data will be required to detect temporal and spatial patterns that may exist. Ultimately it is hoped that this program will prove to be a simple method of characterizing estuarine health that community groups will find both useful and easy to apply
Acute and chronic toxicity of two formulations of the pyrethroid pesticide deltamethryn to an amphipod, sand shrimp and lobster larvae( Book )

4 editions published in 2010 in English and held by 5 WorldCat member libraries worldwide

Pyrethroid insecticides are among the most toxic insecticides known, and among the pyrethroids, deltamethrin is often the most toxic to crustaceans in comparative tests. Two formulated deltamethrin products are in use in Atlantic Canada. The agricultural formulation is called Decis and the aquaculture formulation is called AlphaMax. The objectives of this study were to use marine crustaceans to measure acute toxicity of deltamethrin formulations in sea water using conventional 96-hr toxicity test methods, 1-hr pulse exposures and chronic and sublethal toxicity tests. The marine organisms chosen for this study were: Homarus americanus, the American lobster (a decapod crustacean); Crangon septemspinosa, the sand shrimp (a decapod crustacean); and Eohaustorius estuarius, a marine amphipod (an amphipod crustacean). These organisms are relevant to the study of pesticide toxicity at environmentally relevant concentrations for the marine environment of Atlantic Canada.--Includes text from document
Calibration exercise for the Community Aquatic Monitoring Program (CAMP) nutrient analyses : establishing variability between filtered and unfiltered water samples and two analytical laboratories by M.-H Thériault( Book )

3 editions published in 2012 in English and held by 2 WorldCat member libraries worldwide

As part of the Community Aquatic Monitoring Program (CAMP) unfiltered water samples were collected between 2006 and 2008 and analyzed for dissolved inorganic nutrients by the Bedford Institute of Oceanography (BIO). In 2009 the nutrient component of CAMP was suspended because BIO could no longer process the samples. As a result, steps were undertaken to have the Maurice Lamontagne Institute (MLI) analyze future nutrient samples. MLI conducts analyses for nitrate, nitrite and phosphate, using similar equipment and methodologies as BIO, but recommends filtered samples whereas BIO recommends unfiltered samples. Therefore, before changing laboratories a calibration exercise between laboratories (BIO and MLI) and between filtered and unfiltered water samples was carried out in August 2009 with water samples collected from six CAMP sites. This report describes the results of this calibration exercise.--Document
Preliminary carrying capacity analysis of current and future aquaculture scenarios in Malpeque Bay (Prince Edward Island) by R Filgueira( Book )

3 editions published in 2014 in English and held by 1 WorldCat member library worldwide

Mussel aquaculture in Prince Edward Island (PEI) has grown rapidly into a vital industry since the 1970s. Presently, however, there are very few sites in PEI where water is sufficiently deep to support new farming operations. The present study investigated the mussel carrying capacity of Malpeque Bay by means of computer modeling. A full spatial hydrodynamic-biogeochemical coupled model, integrating a series of known interactions between the cultured mussels and their environment, was developed. The main objective was to gauge the impact of current and future aquaculture scenarios on phytoplankton food resources (chlorophyll a).--Document
Workshop on the lobster (Homarus americanus) fishery data collection pilot project and general data collection issued held in Moncton, New Brunswick, 16-17 February 2009 abstracts and proceedings by Workshop on the Lobster (Homarus Americanus) Fishery Data Collection( )

2 editions published in 2011 in English and held by 0 WorldCat member libraries worldwide

A workshop on lobster (Homarus americanus) fishery data collection was held in Moncton, New Brunswick, on February 16-17, 2009 to convene all stakeholders of the lobster industry and encourage an exchange of ideas on various data collections issues. A total of 61 participants attended the workshop mainly from the Atlantic Provinces, but also from Quebec, the Department of Fisheries and Oceans Canada (DFO) headquarters in Ottawa, and invited guests from Iceland. A total of 15 presentations were given. The outcome of a pilot project on lobster data collection was presented which received great support from all stakeholders. The 3-year pilot project consisted of buyers recording fishery information in situ from harvesters with a handheld computer and a portable printer while catches were off-loaded. The recorded catch and effort data were then transferred daily to a DFO server through an Ethernet connection making them accessible to DFO scientists and managers. Possible challenges and opportunities associated with the project's continuation were discussed, and there was a general consensus that lessons learned from the project will be useful for the development of a broad-scale electronic fishery data collection system. The intent of the workshop was also to emphasize on the importance of timely and reliable fishery data. DFO scientists have been requesting better data since the 1980s, which was also echoed in two Fisheries Resource Conservation Council reports on lobster (1995 & 2007) where the need for adequate data was identified as a prerequisite for the proper management of the fishery. Market accessibility and competitiveness, traceability, eco-certification, and demonstration of a sustainable fishery were also recognized as compelling forces towards accurate and reliable lobster fishery data and the need to create an efficient data collection system. All participants recognized that the present landing reporting system needs to be improved and updated to take advantage of current technologies. It was also stressed that there should be one gatekeeper for all fishery data and that comprehensive databases should be made available to all users base on legally-bound sharing principles. Examples of other data collection systems and/or procedures in other fisheries were presented to demonstrate how the out of date DFO's current system is despite being used for the most valuable fishery in the Gulf region. The extensive data collection system implemented by the Directorate of Fisheries in Iceland represents, in many aspects, the best approach for easy and efficient fisheries monitoring and transparent management of public resources. At the conclusion of the workshop, a brief presentation was made by DFO's Fisheries Management Division to announce the creation of a working group to review the issues associated with the electronic collection of lobster fishery data, and to explore possible solutions. Extended abstracts from most of the presentations at the workshop are presented in this document, as well as a summary of key elements that were discussed following the presentations

An atlas of the January distribution of selected marine fish species in the Cabot Strait from 1994 to 1997 by G. A Chouinard( )

2 editions published in 2011 in English and held by 0 WorldCat member libraries worldwide

The geographic distribution of 25 marine fish species was examined using data collected during bottom trawl surveys conducted each January from 1994 to 1997. Over 90 species / species groups were captured during the four years of surveys. The geographic distribution of the 25 marine fish species that comprised 98% of the catches by weight is described. An analysis of diel differences in catchability was first conducted and correction factors were applied for 4 species. Standardized catches (in numbers and weights) were contoured using Delaunay triangulation. For seven commercial species, the distribution is described for fish smaller and larger than the minimum regulated size or size at maturity. High concentrations of commercial species were found throughout the area surveyed except in the shallowest areas. The results suggest that the Cabot Strait is an important over-wintering area for many fish populations, some of which are found in the Gulf of St. Lawrence during the summer
