Описание: This document assesses tilapia farming and the value chain in Brazil by examining tilapia farming technology and practices, evaluating the sector's social and economic performance, discussing the importance of proper governance, and highlighting opportunities and challenges in the development of tilapia farming, as well as aquaculture in general, in Brazil. The analysis shows that, in Brazil, agribusiness has undergone profound changes in the past few decades, and technological innovations have made the country one of the largest food exporters in the world. Tilapia has been the largest aquaculture item, contributing to nearly half of the country's aquaculture production tonnage in 2017. Aquaculture production increased 14 percent annually, from 13 000 tonnes in 1987 to 595 000 tonnes in 2017, making it a regional aquaculture powerhouse that represented 20 percent of production in Latin America and the Caribbean in 2017. However, institutional instability and regulatory uncertainties pose a challenge to the development of the tilapia industry. For this reason, the report suggests improving public-private partnerships to create an enabling environment for Brazil to fully harness its comparative advantages in tilapia farming. Participatory communication and consultation would also help to create a road map to help Brazil’s tilapia aquaculture develop into an economically viable, environmentally sustainable and socially responsible sector.
Описание: This first ever global assessment of aquatic genetic resources (AqGR) presents a snapshot of the current status of AqGR and also constitutes a valuable technical reference document, providing standardized terminology and concepts.
Описание: This book is divided into three thematic areas. The first covers a revision of the taxonomy of algae, based on the algae portal, as well as the general aspects of biology and the methodologies used in this branch of marine biology. The second subject area focuses on the use of algae in environmental assessment, with an intensive implementation in Western economies and some emerging economies. The third topic is the potential use of algae in various industries including food, pharmaceuticals, cosmetics, agricultural fertilizers, and the emerging biofuels industries.

Описание: Algae have been used since ancient times as food, fodder, fertilizer and as source of medicine. Nowadays seaweeds represent an unlimited source of the raw materials used in pharmaceutical, food industries, medicine and cosmetics. They are nutritionally valuable as fresh or dried vegetables, or as ingredients in a wide variety of prepared foods. In particular, seaweeds contain significant quantities of protein, lipids, minerals and vitamins. There is limited information about the role of algae and algal metabolites in medicine. Only a few taxa have been studied for their use in medicine. Many traditional cultures report curative powers from selected alga, in particular tropical and subtropical marine forms. This is especially true in the maritime areas of Asia, where the sea plays a significant role in daily activities. Nonetheless, at present, only a few genera and species of algae are involved in aspects of medicine and therapy. Beneficial uses of algae or algal products include those that may mimic specific manifestations of human diseases, production of antibiotic compounds, or improvement of human nutrition in obstetrics, dental research, thallassotherapy, and forensic medicine.

Описание:
Apart from being commercially and socially significant, anchovies and sardines populations occupy crucial positions in the oceans' ecosystems. Low in the food chain, clupeoids tend towards abundance, as if their purpose in life was to be eaten and fuel the upper levels of marine trophic chains. The present book covers a broad spectrum of topics on the biology (sytematics, phylogeography, reproduction, feeding) and ecology (habitat characterization, recruitment variability) of anchovies and sardines. It also puts together important information on the state of their fisheries, exploitation, and management.

Описание: This book is an important addition to the knowledge of lobster research. The book complements other books published on lobster research and management as it focuses on Indian lobster fisheries and aquaculture developments where there have been nearly 350 research papers and reports and 19 PhD awards. The book has 15 chapters written by international experts covering many aspects of the biology of a number of spiny and slipper lobster species occurring in India and world oceans with maps illustrating global distribution of spiny lobster families, genera and species. An updated taxonomy and checklist of marine lobsters, the status and management of lobster fisheries in India and Indian Ocean Rim countries and a review of aquaculture research in India and other major countries have also been presented. The book is timely as the 2nd International Indian Ocean Expedition (IIOE) is currently underway (2015-2020), 50 years after the original IIOE (1959-1965), with some of the original lobster research on the biology and distribution of phyllosoma larvae being undertaken on the plankton samples collected during the first IIOE. Many of the chapters are contributed by the authors from Central Marine Fisheries Research Institute (CMFRI), which has been collecting fishery and biological data on lobsters since 1950 when lobster fishing began on a subsistence scale, followed by some industrial fishing for lobsters in different parts of India. Unfortunately, the development of some of these lobster fisheries was followed by overfishing due to lack of enforcement of regulations. The book provides a valuable addition to our knowledge of the biology, fisheries and aquaculture of spiny and slipper lobsters.

Описание:
This book on ancient fishes unites the work of many specialists coming from different areas of biology. Hagfishes, lungfishes, Chondrosteans, and Holosteans constitute the main subject of study. Fossil records and extant species are compared to establish the conservation or the degeneration of specific characters. However, phylogenetic relationships have mostly been revisited in the light of new molecular and developmental data. The morphology of several organs is also revisited.
This volume includes a phylogenetic account of the cardiac outflow tract, and the particulars of the heart and circulation in lungfishes. The control of breathing and the lung-swim bladder issue is discussed. The developmental anatomy of the sturgeon gut and accounts of the gut structure in lungfishes and garfishes are also included. Biochemical and physiological aspects of the behavior of lungfishes and gars are presented. Reports on the fish olfactory system, and on the amazing slime glands of hagfishes, are also covered.

Описание:
Anguillid eels have fascinated biologists for centuries due to their spectacular long-distance migrations between freshwater habitats and their spawning areas far out in the ocean. This book provides a long overdue update on the biology and ecology of anguillid eels and features comprehensive coverage of the key features of the genus Anguilla. It covers a broad spectrum of topics on the biology (taxonomy, phylogeny, evolution, reproduction, feeding, salinity adaptation) and ecology (life history, recruitment, migration) of anguillid eels. It also brings together important information on the state of eel fisheries, conservation, exploitation, and management.
