Genetic Resources of Neotropical Fishes by Alexandre W. S. Hilsdorf,Eric M. Hallerman Pdf
The aim of this book is to systematize and discuss population genetic studies of freshwater fish in a region that harbors the greatest diversity of species among all inland water ecosystems. This volume explores the genetic evaluation for a number of orders, families and species of Neotropical fishes, and provides an overview on genetic resources and diversity and their relationships with fish domestication, breeding, and food production.
Genetic Resources of Neotropical Fishes by Anonim Pdf
The fish faunas of continental South and Central America constitute one of the greatest concentrations of aquatic diversity on Earth, consisting of about 10 percent of all living vertebrate species. National policies have historically encouraged unsustainable practices, and recent decades have witnessed a sharp increase in harmful activities. Conservation of the Neotropical fish diversity is a key target to maintain world fish functional diversity, but this should not hide the pressing need to conserve the vulnerable fish faunas of the rest of the world, in which functional diversity is to a large extent supported by threatened species.Genetic Resources of Neotropical Fishes is focused on identifying and differentiating the myriad species, circumscribing their habitats and geographic ranges, and resolving their phylogenetic interrelationships. It explores the genetic evaluation for a number of orders, families and species of Neotropical fishes, and provides an overview on genetic resources and diversity and their relationships with fish domestication, breeding, and food production. Neotropical fish species show an amazing variety of sex chromosome systems, where different stages of differentiation can be found, ranging from homomorphic to highly differentiated sex chromosomes. Here, we draw attention on the impact of recent developments in molecular cytogenetic analyses that helped to elucidate many unknown questions about fish sex chromosome evolution, using excellent characiform models occurring in the Neotropical region, namely the Erythrinidae family and the Triportheus genus.In relation to populations in Neotropical marine waters, the studies have shown the presence of cryptic species, which has important implications for fishery management. Different levels of genetic structuring can be found among Neotropical freshwater migratory fish species. This raises important implications for fish population genetic diversity and consequently its sustainable utilization in inland fisheries and aquaculture, specifically for conservation of ichthyo-diversity and survival. This book serves as beneficial guide to students, academic researchers and fish scientists worldwide to know more about the genetic value of the richest fish diversity in the world.
Genetics, Evolution, and Conservation of Neotropical Fishes by Rodrigo A. Torres,Roberto Ferreira Artoni Pdf
Fish represent the most ancestral and specious group of vertebrates, and occupy more diverse aquatic environments around the world. Ichthyofauna is extremely diverse, especially in megadiverse countries occupying biogeographical regions such as the Neotropical Region, which covers an extensive area between North and South America. Much of this biodiversity will be extinct, even before science knows any aspect of its biology. Like this, Neotropical fish genetics started in the end of the 70’s with papers studying the chromosomes of Hoplias malabaricus (Family Erythrinidae) and the karyotype variation among three genera of the family Anostomidae. The topic at that time was concentrated in two Institutions from the state of São Paulo, Southeastern Brazil. In the middle 80’s, the first Symposium on Neotropical Fish Cytogenetics was organized. Nowadays, the field of Neotropical Fish Genetics is present in Brazil, Colombia, Argentina, Uruguai, Venezula, Chile, and Equador, as well as outside South America in Panama, Mexico, USA, Canada, Czech Republic, Germany, and Spain. The research developed in cytogenetics has focused mainly on karyotype evolution and cytotaxonomy, chromosome structure and, more recently, cytogenomics. In relation to the use of molecular markers, support has been sought for the management of populations for conservation or production in captivity. In addition, many studies have been carried out with the aim of establishing supra-specific phylogenetic relationships and clarifying species distribution scenarios by phylogeographic modeling. The genome and transcriptome of some model species begin to emerge as extremely promising and informative areas for neotropical fish. In 2017, the Neotropical fish genetics research community celebrates the 30th anniversary of its main Meeting (today entitled Symposium on Neotropical Fish Genetics and Cytogenetics). This Research Topic is part of this celebration and aims at reporting the state of the art and its current advances in the frontier of knowledge in genetics, evolution, and conservation of neotropical fish, as well as to detect the challenges to be overcome in the next years.

The State of the World’s Aquatic Genetic Resources for Food and Agriculture by Food and Agriculture Organization of the United Nations Pdf
The conservation, sustainable use and development of aquatic genetic resources (AqGR) is critical to the future supply of fish. The State of the World’s Aquatic Genetic Resources for Food and Agriculture is the first ever global assessment of these resources, with the scope of this first Report being limited to cultured AqGR and their wild relatives, within national jurisdiction. The Report draws on 92 reports from FAO member countries and five specially commissioned thematic background studies. The reporting countries are responsible for 96 percent of global aquaculture production. The Report sets the context with a review of the state of world’s aquaculture and fisheries and includes overviews of the uses and exchanges of AqGR, the drivers and trends impacting AqGR and the extent of ex situ and in situ conservation efforts. The Report also investigates the roles of stakeholders in AqGR and the levels of activity in research, education, training and extension, and reviews national policies and the levels of regional and international cooperation on AqGR. Finally, needs and challenges are assessed in the context of the findings from the data collected from the countries. The Report represents a snapshot of the present status of AqGR and forms a valuable technical reference document, particularly where it presents standardized key terminology and concepts.
