Following a short introduction to the species and its closest commercially viable related species, namely pirapatinga (Piaractus brachypomus) and pacu (Piaractus mesopotamicus), this field guide provides practical information on the culture and reproduction of tambaqui (Colossoma macropomum). As a field guide it aims to support the understanding and dissemination of applicable technologies for the culture and reproduction of tambaqui, i.e. what should be done – as well as when and how it should be done – in order to achieve success in the artificial propagation as well as the fingerling and table fish production stages. The concise technical descriptions in this guide are accompanied by self-explanatory illustrations and a reader-friendly glossary of technical terms, which is important for tambaqui aquaculture farmers.

Experts are predicting that demand for marine fish oil will soon outstrip supply, creating extreme urgency within the global aquafeed industry to find viable alternatives. Fish Oil Replacement and Alternative Lipid Sources in Aquaculture Feeds is the first comprehensive review of this multifaceted, complex issue. It also addresses the crucial questions about whether or not the industry will be able to meet increasing worldwide demand for fisheries products. The First & Only Book Specifically Addressing this Issue With contributions from more than 30 international experts, the book provides a global perspective on the production, rationale, and use of fish oils, vegetable oils, and animal fats in relation to the aquaculture and aquafeed industries. After a detailed discussion on alternative lipid sources, the book discusses groundbreaking research on the use of these lipid sources as fish oil substitutes, as well as their potential advantages and challenges for use in aquafeeds. Written by Leading Scientists & Industry Authorities Rounding out its solid coverage, the book then explores the important physiological effects of various lipid sources and their components on growth, lipid metabolism, health, and postharvest qualities of the farmed fish. Both timely and pertinent, Fish Oil Replacement and Alternative Lipid Sources in Aquaculture Feeds is the most authoritative and comprehensive review on the substitution of fish oil in aquaculture feeds addressing the issues, science, and future directions of using sustainable alternatives.

This paper focuses on millennials who are increasingly looking to find their way in the sharing economy, a phenomenon made possible by the emergence of digital platforms that facilitate the matching of buyer and seller. Jobs in the sharing economy—like driving for Uber or Lyft—help some millennials make ends meet, even if such temporary gigs are a far cry from the fulltime jobs with traditional pension plans and other benefits their parents often enjoyed. This generation also enthusiastically embraces the services of the sharing economy, which provides access to everything from beds to cars to boats without the hassle of ownership. Loath to buy big-ticket items such as cars and houses, millennials have sharply different spending habits from those of preceding generations. Millennials confront obstacles to prosperity that their parents didn’t face. They are better educated than previous generations—but in today’s world, that is not enough to guarantee financial success.

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.

The knowledge of isolation and identification of bacteria from aquatic animals and the aquatic environment is expanding at a rapid rate. New organisms, be they pathogens, environmental, normal flora, or potential probiotics, are being described and reported each month. This has resulted due to increases in aquaculture research, in intensive fish farming systems, and in the international trade of live aquatic animals and products as well as the emergence of new diseases. This manual provides a source that enables the identification of bacteria that may be found in animals (particularly fish) that inhabit the aquatic environment. The emphasis is on bacteria from farmed aquatic animals.

Aquaculture pond managers measure water-quality variables and attempt to maintain them within optimal ranges for shrimp and fish, but surprisingly little attention is paid to pond soil condition. Soil-water interactions can strongly impact water quality, and soil factors should be considered in aquaculture pond management. The importance of soils in pond management will be illustrated with an example from pond fertilization and another from aeration. Pond fertilization may not produce phytoplankton blooms in acidic ponds. Total alkalinity is too low to provide adequate carbon dioxide for photosynthesis, and acidic soils adsorb phosphate added in fertilizer before phytoplankton can use it. Agricultural lime stone application can raise total alkalinity and neutralize soil acidity. The amount of limestone necessary to cause these changes in a pond depends on the base unsaturation and exchange acidity of the bottom soil. Two ponds with the same total alkalinity and soil pH may require vastly different quantities of limestone because they differ in exchange acidity. Aeration enhances dissolved oxygen concentrations in pond water and permits greater feed inputs to enhance fish or shrimp production. As feeding rates are raised, organic matter accumulates in pond soils. In ponds with very high feeding rates, aeration may supply enough dissolved oxygen in the water column for fish or shrimp, but it may be impossible to maintain aerobic conditions in the surface layers of pond soil. Toxic metabolites produced by microorganisms in anaerobic soils may enter the pond water and harm fish or shrimp.
