Book Synopsis Recent Trends in the Abundance of the Invasive Green Crab (Carcinus Maenas) in Bras D'Or Lakes and Eastern Nova Scotia Based on Trap Surveys by : M. J. Tremblay
Download or read book Recent Trends in the Abundance of the Invasive Green Crab (Carcinus Maenas) in Bras D'Or Lakes and Eastern Nova Scotia Based on Trap Surveys written by M. J. Tremblay and published by . This book was released on 2006 with total page 40 pages. Available in PDF, EPUB and Kindle. Book excerpt: Trapping surveys for the invasive green crab (Carcinus maenas) were undertaken in Eastern Nova Scotia and in the Bras d'Or Lakes in 1999-2000 and 2005. Interviews were also conducted with fishermen and other coastal inhabitants. Green crab were widespread throughout the sampling area and showed no change in range over the time period. Green crab abundance either decreased or did not change between 1999-2000 and 2005. Catch rates of green crab in the Bras d'Or Lakes were lower in 2005 than the earlier period. The decline in green crab abundance in Bras d'Or Lakes was not clearly linked to lower water temperatures. Outside of the Bras d'Or Lakes, there were no significant differences in green crab catch rate between 1999-2000 and 2005.--Abstract.

This book was released on 2015 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Environmental management is becoming more informed through the use of less conventional knowledge sources to understand environmental systems. Following this realization, our study accesses both local and scientific knowledge to improve understanding of which environmental factors drive local-scale distribution of an invasive species, the European Green Crab (Carcinus maenas L.). It also attempts to understand how C. maenas behaviour might differ in the South Shore area of Nova Scotia, Canada. We synthesized scientific knowledge through an extensive literature review, while interviewing local South Shore fishermen who have experience with C. maenas. While several environmental factors are delineated, our research also notes internal (i.e. age, sex, moult phase) and temporal (i.e. seasonal, tidal, diel) variables that affect local distribution patterns. Local knowledge of this species is still developing, however it may play a significant role in understanding the local distributions and movements of this species, especially as knowledge develops.

This book was released on 2015 with total page 88 pages. Available in PDF, EPUB and Kindle. Book excerpt: The European Green Crab, Carcinus maenas is native to coastal areas from northern Europe to North Africa. It is also a highly invasive species worldwide with reproductive populations in Australia, South Africa, North America and South America. In British Columbia, European Green Crabs were surveyed from 2006 to 2013. Data collected during annual surveys was used to elucidate C. maenas distribution, life history, growth and reproductive habits on the coast of British Columbia. Niche overlap with local crabs and other marine species was described in order to understand ecological impacts on native species by the establishment of C. maenas in British Columbia. In this document, methods and results related to location and catch rates, crab sizes, sex ratio and eggs, shell condition and colour, age structure and recruitment, native crab species, and bycatch are presented.--Includes text from document.
Book Synopsis A Handbook of Global Freshwater Invasive Species by : Robert A. Francis
Download or read book A Handbook of Global Freshwater Invasive Species written by Robert A. Francis and published by Routledge. This book was released on 2012-03-12 with total page 918 pages. Available in PDF, EPUB and Kindle. Book excerpt: Invasive non-native species are a major threat to global biodiversity. Often introduced accidentally through international travel or trade, they invade and colonize new habitats, often with devastating consequences for the local flora and fauna. Their environmental impacts can range from damage to resource production (e.g. agriculture and forestry) and infrastructure (e.g. buildings, road and water supply), to human health. They consequently can have major economic impacts. It is a priority to prevent their introduction and spread, as well as to control them. Freshwater ecosystems are particularly at risk from invasions and are landscape corridors that facilitate the spread of invasives. This book reviews the current state of knowledge of the most notable global invasive freshwater species or groups, based on their severity of economic impact, geographic distribution outside of their native range, extent of research, and recognition of the ecological severity of the impact of the species by the IUCN. As well as some of the very well-known species, the book also covers some invasives that are emerging as serious threats. Examples covered include a range of aquatic and riparian plants, insects, molluscs, crustacea, fish, amphibians, reptiles and mammals, as well as some major pathogens of aquatic organisms. The book also includes overview chapters synthesizing the ecological impact of invasive species in fresh water and summarizing practical implications for the management of rivers and other freshwater habitats.

This book was released on 2021 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: "Global food waste is an issue that we are faced with each and every day. Poor management practices at each level of the food chain contributes to the overall loss of food. The fishery and aquacultural industry, for instance, generates a large percentage of unavoidable waste and losses that are rich in nutrients, such as proteins, lipids, and pigments. Therefore, the use of fishery waste to generate value-added products is a part of sustainable practices that have become a growing trend to reduce global food waste altogether. However, another form of waste that lacks exposure is the destruction of invasive aquatic species in nature. European green crab (Carcinus maenas) is an underutilized invasive species distributed on the shallow waters in the northern-western Atlantic coastline. Green crabs are known to be a very small aggressive specie with a large appetite that poses a threat to Canadian ecosystems and the fishery industry. Currently, the green crab has little use as a food source, and are often discarded into the environment as waste. Thus, there is an interest to explore green crab to generate high value-added products. In this study, the biochemical composition and enzyme-assisted extraction of carotenoprotein and chitin from green crab were investigated. Initially, green crab harvested from Nova Scotia coastline was analyzed for lipid and protein composition. The crab samples contained comparable crude protein (20.98% dry wt. basis) and lipid (3.00 % dry wt. basis) content as those previously published in the literature. The lipid profile of green crab characterized using GC-MS showed a higher content of unsaturated fatty acids, including MUFAs mainly, oleic acid and PUFAs, such as EPA and DHA. Furthermore, carotenoprotein is a natural pigment comprised of a carotenoid and protein complex found in crustacean shells. The use of proteases, such as trypsin, is a mild and successful method to extract carotenoprotein from crab shells. The enzyme-assisted extraction with the aid of trypsin from porcine pancreas yield green crab carotenoprotein extract consisting of 67.58 % total soluble protein and 139.26 μg/g carotenoids. The amino acid analysis showed carotenoprotein extract was rich in essential amino acids (49.87 %), hydrophobic amino acids (44.17 %), and dominant in aspartic acid, asparagine, glutamic acid, and glutamine amino acids. Also, thin layer chromatography indicated the main carotenoids in carotenoprotein were astaxanthin and astaxanthin diester. The combined effect of carotenoid, amino acids, and peptides from extracted carotenoprotein showed the highest antioxidant activities at 4 mg/mL against DPPH and hydroxyl radicals and iron-reducing power. Moreover, crab shells are an excellent source to generate chitin for biomedical or pharmaceutical applications. However, the high content of ash (38.05 %) in green crab indicated that an extensive demineralization step was required to generate quality chitin. Consequently, the optimization of citric acid demineralization using Box-Behnken design to investigate the effects of time, concentration, and temperature on the total residual ash was conducted. The optimal condition was determined as 1.0 M of citric acid, at a temperature of 4"°C" and time of 18h to obtain 1.38 % total residual ash in green crab. The mineral analysis of green crab using ICP-MPS showed the shells were rich in calcium (196 mg/g ), sodium (16.4 mg/g ), phosphorous (12.8 mg/g), magnesium (8.50 mg/g), potassium (5.20 mg/g) and strontium (2.74 mg/g). However, extracted chitin following optimal demineralization conditions showed relatively lower levels of sodium (4.20 mg/g), calcium (1.40 mg/g), and phosphorous (0.900 mg/g). Chemical characterization using XRD analysis further confirmed CaCO3 was effectively chelated with citric acid. The extracted chitin showed characteristic bands similar to commercial crab chitin, following FTIR analysis, indicating a potential source for further application"--

Available in PDF, EPUB and Kindle. Book excerpt: Hardbound. Clams have been harvested along the coasts of North America for as long as records have been kept. They support commercial, sport and subsistence fisheries although unfortunately, with few exceptions, the harvest of these invertebrates is declining. This decline is probably caused by a number of factors including pollution and overfishing. In an effort to ameliorate this situation, interest in the aquaculture of these species has grown.Intensive semi-controlled clam culture has been attempted in North America for almost three decades. However, it was not until the last decade that a number of entrepreneurs actually began clam farming and developing successful and profitable operations. This success has been possible because of numerous scientific and practical contributions made by a great number of scientists, growers, and clammers over the years, and by a healthy market demand caused by a downward trend in the wild harvest.Many of the

Download or read book Ecological Comparisons of Sedimentary Shores written by K. Reise and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 392 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sedimentary coasts with their unique forms of life and productive ecosystems are one of the most threatened parts of the biosphere. This volume analyzes and compares ecological structures and processes at sandy beaches, tidal mudflats and in shallow coastal waters all around the world. Analyses of local processes are paired with comparisons between distant shores, across latitudinal gradients or between separate biogeographic provinces. Emphasis is given to suspension feeders in coastal mud and sand, to biogenic stabilizations and disturbances in coastal sediments, to seagrass beds and faunal assemblages across latitudes and oceans, to recovery dynamics in benthic communities, shorebird predation, and to experimental approaches to the biota of sedimentary shores.
