Fish and shellfish are contributing highly nutritious and healthy food to the food basket the world over. The world per capita seafood consumption reached a record level of 20 kg per person per year for the first time in history. This is twice the level of average per capita fish consumption in 1960s in the world. The global trade value of seafood has increased to $ 150 billion. The total fish production in the world is 150 million tons in 2014 (FAO) out of which 70 million tons is contributed by aquaculture. While the natural capture fishery resources are fast dwindling, contribution by aquaculture is ever increasing. The culture of crustaceans and finfishes is propelled mainly by intentional feeding of formulated feeds. As the demand for fish as food for human consumption is ever-increasing, aquaculture is the only alternative to bridge the gap between supply and demand. Indian aquaculture production has shown impressive growth with total aquaculture production nearing 7 million tons contributing almost 70% to the total seafood production. Indian aquaculture sector is mainly represented by the large scale culture of Indian Major Carps (catla, rohu and mrigal), exotic carps (grass carp, silver carp and common carp) and Pangasius catfish. Freshwater prawn and Penaeid shrimp are the crustaceans that are adding to seafood exports from the country. Aquaculture of Asian seabass, milkfish, mullets, grouper and cobia etc. has been gaining momentum. The total aqua feed production is touching almost 300,000 tons per annum.
This book uses real-world examples from the aquaculture industry to demonstrate how deep technology is assisting farmers and vulnerable communities. Works conducted by Poseidon-AI (a deep tech company involved in the aquaculture sector) in different countries are presented as case studies to show the positive impacts of deep tech involvement in the aquaculture sector. Primary industries, such as fisheries and aquaculture, rely heavily on labor. Furthermore, the manual practices of these farming methods increase material waste and reduce yields, resulting in higher costs and lower revenues. Poikilotherms make up the majority of aquatic animals, and environmental changes have a significant impact on them. This means that, due to climate change, farming of these animals cannot continue in the same way that it has for centuries. Artificial intelligence, machine learning, image processing, sensing, and automation are approaches that can assist these farms in dealing with rapid environmental changes while also assisting farmers in growing their businesses sustainably. This book is of interest to climate change scientists, entrepreneurs, investors, civil workers, and policymakers. Furthermore, the book is a great complimentary material for graduate students of fisheries, aquaculture, ecology, soil science, water management and environmental sciences. All national and international policymakers working in implementation of UNSDGs and sustainability, will find this book a useful read.
With reference to India.
Aquaculture now supplies half of the seafood and fisheries products consumed worldwide and is gaining international significance as a source of food and income. Future demands for seafood and fisheries products can only be met by expanded aquaculture production. Such production will likely become more intensive and will depend increasingly on nutritious and efficient aquaculture feeds containing ingredients from sustainable sources. To meet this challenge, Nutrient Requirements of Fish and Shrimp provides a comprehensive summary of current knowledge about nutrient requirements of fish and shrimp and supporting nutritional science. This edition incorporates new material and significant updates to information in the 1993 edition. It also examines the practical aspects of feeding of fish and shrimp. Nutrient Requirements of Fish and Shrimp will be a key resource for everyone involved in aquaculture and for others responsible for the feeding and care of fish and shrimp. It will also aid scientists in developing new and improved approaches to satisfy the demands of the growing aquaculture industry.
Fish Nutrition, Fourth Edition is an up-to-date, authoritative presentation of all key elements of the nutrition of fish and crustaceans. As aquaculture is rapidly expanding, more than 200 herbivorous and carnivorous species occupy a diverse range of ecological niches, and have therefore evolved to utilize a wide array of food sources. This new edition highlights these differences and covers the complexity and challenges associated with fish nutrition, addressing nutrient requirements to produce high-quality, healthful and sustainable resources, the essential nutrients for fish species, including proteins and amino acids, vitamins, minerals and essential fatty acids, a feed quality assessment, and fish pathology. Led by a team of international experts, this edition provides readers with new information on the use of high-throughput technologies in fish nutrition research, the role of feeds on the community structure of the microbiome, and advances in essential nutrient requirements. - Features expansive updates to the previous edition, including a new chapter dedicated to diet analysis and evaluation - Addresses the roles of fish nutrition and feeds on sustainability and the environmental impacts of aquaculture - Covers basic nutritional biochemistry and applied nutritional topics
This book provides descriptive information on fisheries and nutrition, and outlines actions that could be taken to enhance the contribution of fisheries to the alleviation of malnutrition. It derives generalizations regarding the evaluation and design of fisheries projects and fisheries policies. .
Coastal areas are commonly defined as the interface or transition areas between land and sea, including large inland lakes. Overall, about 50–70 % of the global population live within 100 km of the coastline covering only about 4 % of earth’s land, thereby drawing heavily on coastal and marine habitats for food, building sites, transportation, recreational areas, and waste disposal. The people of these zones depend mainly on low productive agriculture due to several constraints such as prolonged water logging and drainage congestion in predominantly low-lying areas with heavy soils during the wet season, preponderance of saline and acid sulphate soils, scarcity of good quality irrigation water, particularly in the dry season, seawater intrusion into adjoining lands, and water pollution due to eutrophication, and others affecting the aquatic habitats, etc. Carbon sequestration in coastal areas, such as, marshes, lagoons, etc. has significant influence on soil quality, and the carbon pool in soils as well as their impacts on the environment. Over and above these, the coastal areas are prone to disasters due to climate change leading to colossal loss of lives and properties in many areas. Forestry and mangrove dynamics, in particular, because of their continuing diminishing nature, are also subjects of interest affecting the ecology of coastal zones requiring appropriate attention. The international symposium held in this context on ‘ Transforming Coastal Zones for Sustainable Food and Income Security ’ in virtual mode in March, 2021 offered scope to present and discuss various thematic areas by eminent scientists from all over the world. The proceedings of selected papers presented reflect cross-sectoral views of the areas highlighting, wherever necessary, a fusion of technologies, with the ultimate target to suggest livelihood security and sustainable development for the sensitive coastal zones. The book intends to share the knowledge with researchers, academicians, and various other stakeholders to address the complex problems of coastal regions, production constraints, social, economic, technical and environmental issues to draw out strategies for resilient agricultural technologies and improving livelihood security in coastal agro-ecosystems.
The book on Fish Nutrition and Its Relevance to Human Health is an important document in filling the gap of requisite fish nutrition and sustainable aquaculture in different agro-climatic zones and its relevance to human health. The book includes 14 chapters addressing various aspect of nutritional requirement of cultivable finfishes of freshwater, brackish water and marine eco systems including cold water and valley region fisheries. Various aspects on larval and adult feeding with cultivation and intensification of live food organisms including copepods is discussed. Aspects on immunomodulation, role of digestive enzymes and nutraceuticals, probiotics including nutrigenomics have been well documented. Post harvest and value addition aspects have been the important contribution for fish farming and human nutrition value. A topic has been included on water quality management for safe husbandry practices on bio-flock technology and its relevance for sustainable aquaculture farming systems in a book on fish nutrition and its relevance to human health.
