Book Synopsis Temporal and Spatial Characteristics of the Ciliate Mesodinium Rubrum in the Western Isles Region of the Bay of Fundy by : J. L. Martin
Download or read book Temporal and Spatial Characteristics of the Ciliate Mesodinium Rubrum in the Western Isles Region of the Bay of Fundy written by J. L. Martin and published by . This book was released on 2007 with total page 36 pages. Available in PDF, EPUB and Kindle. Book excerpt: The abundance of the ciliate Mesodinium rubrum has been monitored at five locations in the Bay of Fundy, eastern Canada, at weekly to monthly intervals since 1987. M. rubrum was present at all stations an average of 94% of the sampling dates from 1987 to 2004. The date for the first appearance of M. rubrum in a given year was inter-annually variable and ranged from January to April. Maximum concentrations occurred anywhere between May and October and tended to be earliest at Lime Kiln Bay and the Wolves and latest in the more inshore Passamaquoddy Bay stations and Deadmans Harbour. Brandy Cove, the most inshore station in Passamaquoddy Bay, had the highest concentrations, suggesting that this region was more conducive to the higher cell densities and blooms of M. rubrum. The annual maximum concentration varied among stations and between years by up to 5.7 orders of magnitude. The median maximum value (cells·L−1) was 13740 (Station 3), 12600 (Station 15), 16400 (Station 16), 19460 (Station 17) and 70296 (Station 25). The annual duration of the presence of M. rubrum ranged throughout the year and had a mean of 224 d, whereas the duration of the presence containing the annual maximum concentration varied from 7-365 d. The characteristics of the annual M. rubrum blooms vary between years and stations with the number of blooms or high abundance periods varying from one to two per year

Book Synopsis Phytoplankton Monitoring in the Western Isles Region of the Bay of Fundy During 1997-98 by : J. L. Martin
Download or read book Phytoplankton Monitoring in the Western Isles Region of the Bay of Fundy During 1997-98 written by J. L. Martin and published by St. Andrews, N.B. : Fisheries and Oceans Canada. This book was released on 2001 with total page 94 pages. Available in PDF, EPUB and Kindle. Book excerpt: A monitoring program was initiated in May 1987 to study phytoplankton populations in the Western Isles region of the Bay of Fundy, southwest New Brunswick. This report provides another 2 yr of data to add to the results from 1987-96 published previously. Samples were collected for phytoplankton distribution and abundance as well as plant nutrients (ammonia, nitrate, phosphate and silicate) at four locations - Brandy Cove, Lime Kiln Bay, Deadmans Harbour and the Wolves Islands. Additional parameters measured included secchi depth, and depth profiles for fluorescence, temperature and salinity. Samples were collected at the surface from all locations and additional discrete depths of 10 m, 25 m, and 50 m were sampled at the Wolves. Dominant species (>103 cells L−1) during the 2-yr period were Guinardia delicatula, Leptocylindrus danicus, Leptocylindrus minimus, Mesodinium rubrum, Pseudo-nitzschia delicatissima group, and Skeletonema costatum. M. rub rum and the P. delicatissima group have been observed at concentrations > 10,000 during all of the past 12 yr. Whereas Alexandrium fundyense (the organism responsible for producing paralytic shellfish toxins) concentrations exceeded 103 cells L−1 during the 4 yr 1993-96, during 1997-98, highest concentrations observed were 8.2 x 103 cells L−1 and 6.7 x 103 cells L−1, respectively. During 1998, another sampling site in mid Passamaquoddy Bay was added as a result of concentrations of M. rubrum exceeding one million cells L−1 during a 4-wk period in the northern Passamaquoddy Bay area, which was responsible for low numbers of salmon mortalities. Highest and lowest temperatures (0.4-15.5°C) were measured at Brandy Cove as well as lowest salinities (23.85). Silicate values ranged from 0.44 to 14.6 μM; phosphate levels ranged from 0.34 to 1.13 μM; nitrate values were from 0.03 to 9.87 μM; and ammonia ranged between 1.18 to 6.72 μM

M rubrum and the P. delicatissima group have been observed at concentrations > 10,000 cells·L1 during all of the past 14 yr. Alexandrium fundyense (the organism responsible for producing paralytic shellfish toxins) concentrations exceeded 104 cells·L1 in all but 2 yr during the 1988-96 period, cell densities were 8.2 and 6.7 x 103 cells·L1 in 1997 and 1998, respectively, and the highest concentrations observed during 1999 were 3.2 x 103 cells·L1 in late July, while the highest densities recorded for 2000 were 2.5 x 103 cells·L1. During the 2 yr, the lowest temperature (1.0°C) was measured at Brandy Cove while the highest temperature was recorded at the mid-Passamaquoddy site (17.0°C), both occurring in 1999. Lowest salinities (21.19 psu) were measured at Brandy Cove. Nitrate values ranged from 0.09-12.10 μM; ammonia from 0.04-8.10 μM: nitrite from 0.05-0.68 μM; phosphate levels ranged frmn 0.29-1.26 μM and silicate from 0.30-19.7 μM

Book Synopsis Real-time Coastal Observing Systems for Marine Ecosystem Dynamics and Harmful Algal Blooms by : Babin, Marcel
Download or read book Real-time Coastal Observing Systems for Marine Ecosystem Dynamics and Harmful Algal Blooms written by Babin, Marcel and published by UNESCO. This book was released on 2008-06-05 with total page 880 pages. Available in PDF, EPUB and Kindle. Book excerpt: The proliferation of harmful phytoplankton in marine ecosystems can cause massive fish kills, contaminate seafood with toxins, impact local and regional economies and dramatically affect ecological balance. Real-time observations are essential for effective short-term operational forecasting, but observation and modelling systems are still being developed. This volume provides guidance for developing real-time and near real-time sensing systems for observing and predicting plankton dynamics, including harmful algal blooms, in coastal waters. The underlying theory is explained and current trends in research and monitoring are discussed.Topics covered include: coastal ecosystems and dynamics of harmful algal blooms; theory and practical applications of in situ and remotely sensed optical detection of microalgal distributions and composition; theory and practical applications of in situ biological and chemical sensors for targeted species and toxin detection; integrated observing systems and platforms for detection; diagnostic and predictive modelling of ecosystems and harmful algal blooms, including data assimilation techniques; observational needs for the public and government; and future directions for research and operations.

Book Synopsis Building an Ecosystem Approach to Aquaculture by : Doris Soto
Download or read book Building an Ecosystem Approach to Aquaculture written by Doris Soto and published by Fao Fisheries and Aquaculture. This book was released on 2008 with total page 240 pages. Available in PDF, EPUB and Kindle. Book excerpt: 520 Aquaculture growth worldwide involves the expansion of cultivated areas, a higher density of aquaculture installations and farmed individuals, and greater use of feed resources produced outside the immediate culture area. To ensure that such development of the sector does not carry negative impacts on the environment and on parts of society due to weak regulation or poor management, an ecosystem approach for aquaculture (EAA) is encouraged. These proceedings consider aspects relevant for an ecosystem-based management in aquaculture. The document also includes two comprehensive reviews covering the status of brackish, marine and freshwater aquaculture within an ecosystem approach perspective.--Publisher's description.
Book Synopsis Principles of Salmonid Culture by : W. Pennell
Download or read book Principles of Salmonid Culture written by W. Pennell and published by Elsevier. This book was released on 1996-10-11 with total page 1071 pages. Available in PDF, EPUB and Kindle. Book excerpt: As salmonids have been reared for more than a century in many countries, one might expect that principles are well established and provide a solid foundation for salmonid aquaculture. Indeed, some of the methods used today in salmonid rearing are nearly identical to those employed one hundred years ago. Areas of salmonid research today include nutrition, smolt and stress physiology, genetics and biotechnology.The purpose of this book is to provide a useful synthesis of the biology and culture of salmonid fishes. The important practices in salmonid culture as well as the theory behind them is described. This volume will be of interest to students, researchers, fisheries biologists and managers as well as practising aquaculturists.

Book Synopsis Expanding Mariculture Farther Offshore by : Alessandro Lovatelli
Download or read book Expanding Mariculture Farther Offshore written by Alessandro Lovatelli and published by Food & Agriculture Organization of the UN (FAO). This book was released on 2013 with total page 88 pages. Available in PDF, EPUB and Kindle. Book excerpt: It is also recommended that efforts be increased to farm lower trophic levels species and optimize feeds and feeding in order to minimize ecosystems impacts and ensure long-term sustainability. Similarly, risk assessments and/or environmental impact assessment and monitoring must always be in place before establishing offshore farms, and permanent environmental monitoring must be ensured. All coastal nations should be prepared to engage actively in developing the technological, legal and financial frameworks needed to support the future development of offshore mariculture to meet global food needs. The workshop report highlights the major opportunities and challenges for a sustainable mariculture industry to grow and further expand off the coast.
