Book Description
Fisheries genetics researchers will find invaluable the thirty-eight peer-reviewed contributions in this book, presented at the 20th Lowell Wakefield Fisheries Symposium "Genetics of Subpolar Fish and Invertebrates," held in May 2002 in Juneau, Alaska. Looming over concerns of lost fisheries stocks and persistent erosion of genetic variability are predictions of global warming, which may further tax genetic resources. One consequence is an increased reliance on genetic applications to many aspects of fisheries management, aquaculture, and conservation. The contributions in this book are important to modern fisheries science and genetics, and illustrate the evolution of the field over the past decade. The improved technology provides tools to address increasingly complicated problems in traditional applications and ecological and behavioral studies. The union between molecular and quantitative genetics, where many of the major questions about population structure and evolution remain unanswered, will also benefit from the new technologies.

Book Description
From a global perspective aquaculture is an activity related to food production with large potential for growth. Considering a continuously growing population, the efficiency and sustainability of this activity will be crucial to meet the needs of protein for human consumption in the near future. However, for continuous enhancement of the culture of both fish and shellfish there are still challenges to overcome, mostly related to the biology of the cultured species and their interaction with (increasingly changing) environmental factors. Examples of these challenges include early sexual maturation, feed meal replacement, immune response to infectious diseases and parasites, and temperature and salinity tolerance. Moreover, it is estimated that less than 10% of the total aquaculture production in the world is based on populations genetically improved by means of artificial selection. Thus, there is considerable room for implementing breeding schemes aimed at improving productive traits having significant economic impact. By far the most economically relevant trait is growth rate, which can be efficiently improved by conventional genetic selection (i.e. based on breeding values of selection candidates). However, there are other important traits that cannot be measured directly on selection candidates, such as resistance against infectious and parasitic agents and carcass quality traits (e.g. fillet yield and meat color). However, these traits can be more efficiently improved using molecular tools to assist breeding programs by means of marker-assisted selection, using a few markers explaining a high proportion of the trait variation, or genomic selection, using thousands of markers to estimate genomic breeding values. The development and implementation of new technologies applied to molecular biology and genomics, such as next-generation sequencing methods and high-throughput genotyping platforms, are allowing the rapid increase of availability of genomic resources in aquaculture species. These resources will provide powerful tools to the research community and will aid in the determination of the genetic factors involved in several biological aspects of aquaculture species. In this regard, it is important to establish discussion in terms of which strategies will be more efficient to solve the primary challenges that are affecting aquaculture systems around the world. The main objective of this Research Topic is to provide a forum to communicate recent research and implementation strategies in the use of genomics in aquaculture species with emphasis on (1) a better understanding of fish and shellfish biological processes having considerable impact on aquaculture systems; and (2) the efficient incorporation of molecular information into breeding programs to accelerate genetic progress of economically relevant traits.

Book Description
Devoted to fishes of high latitudes (Arctic and Antarctic). This book includes themes such as: the uniqueness of the physiology of fishes that live in cold polar environments, an analysis of physiological patterns exemplified by fishes that live poles apart, and how fishes differ from fishes living in more temperate and tropical habitats.

Book Description
The Polar and Subpolar region comprise one of the seven regions in the world, from the Arctic to the Antarctic, the Atlantic, Pacific, and Indian Oceans. Marine biodiversity in the polar and subpolar regions is one of the richest on earth, hosting important populations of crustaceans, pelagic and benthic species that provide resources for the many seabirds and marine mammals that congregate there. However, these ecosystems, as well as their biodiversity, are vulnerable and already affected by the impacts of climate change and other threats. The high climatic dynamics in those areas have already generated strong modifications to the environment, with irreversible losses in biodiversity and diminished ecosystem services that are essential for the whole planet. The current need to study and understand the biodiversity of the world's oceans makes polar and sub-polar areas key regions for taxonomic and ecological studies.

Book Description
This open access book provides a comprehensive examination of the European Landing Obligation policy from many relevant perspectives. It includes evaluations of its impacts at economical, socio-cultural, ecological and institutional levels. It also discusses the feasibility and benefits of several potential mitigation strategies. The book was timely published, exactly at the time where the Landing Obligation was planned to be fully implemented. This book is of significant interest to all stakeholders involved, but also to the general public of Europe and to other jurisdictions throughout the world that are also searching for ways to deal with by-catch and discard issues.

Book Description
Effects of Petroleum on Arctic and Subarctic Marine Environments and Organisms, Volume II: Biological Effects examines the biological effects of petroleum on marine ecosystems and organisms in Arctic and subarctic regions. The effects of petroleum on disease and disease resistance in marine fish and invertebrates are analyzed, along with the metabolism of petroleum hydrocarbons and their accumulation and biotransformation in marine organisms. The consequences of oil fouling on marine mammals are also considered. Comprised of nine chapters, this volume begins with a discussion on the acute toxic effects of petroleum on Arctic and subarctic marine organisms, together with the bioassay techniques used to conduct acute toxicity tests. The next chapter assesses the effects of petroleum on marine fish and invertebrates, with emphasis on their disease and disease resistance. Subsequent chapters explore the metabolism of petroleum hydrocarbons and their accumulation and biotransformation in marine organisms; the sublethal effects of petroleum on the physiology, behavior, growth and development, and reproduction of bacteria, algae, and invertebrates; the biological effects of petroleum on fish, birds, and marine mammals; and the effects of oil fouling and oil spills. This book will be of interest to marine scientists and ecologists as well as environmental policymakers.
