  • Fishing for a Solution

    As writer Rowan Jacobsen explores in our recent feature “Has Meat Met Its Match?,” animal agriculture’s hefty environmental footprint is creating interest in exploring ways to meet humans’ growing appetite for animal protein that extend beyond beef, chicken and pork. In some places, that ...

  • The advantages and disadvantages of culturing fish.

    The advantages and disadvantages of culturing fish. Experts develop practical recommendations for decision-makers, scientists and producers for a sustainable development of Mediterranean aquaculture. Human demand for fish is growing steadily. With fisheries decreasing worldwide, aquaculture is becoming an important socio-economic alternative and a source of proteins and healthy oils. ...

  • Qualitative algal analysis from the fish-gut: Tested in the rice fish cropping system

    Abstract: Algae constitute a major proportion of fish food in rice-fish culture system. Study of algal preferences and their availability in the natural environment might be important for developing natural fish feed. Preparation of formulated feeds using under-exploited materials such as algae not only reduces production costs, but also increases procurement accessibility of locally available ...

  • MonoScan for stock management of animal feed case study

    MonoScan provides a reliable and accurate continuous level indication of animal feed. MonoScan is deployed in a very large regional large feed mill. This feed mill supplies feed for poultry, turkeys, ruminants, fish, rabbits, and pigeons. The plant has a modern premix department that produces vitamin and trace mineral premixes for customers by demand. The problems In ...

  • Seasteading could be the answer to sustainably feeding 9 billion people

    Self-sufficient nation states in the middle of the ocean might be our ticket to a sustainable future. Oceans cover 71 percent of Earth’s surface, yet provide less than 2 percent of the food we eat. The growing demand for seafood, however — predicted to rise to 8 percent during the next decade — from an already depleted and exhausted ocean is forcing ...

  • The treatment of (fish) ponds on an environmentally friendly manner with the usage of the LG Sonic case study

    Aquaculture, or aqua farming, is the cultivation of aquatic organisms, such as fish or shrimps, in a controlled environment. Where this happens in a closed water container, algae may occur that pollute the water and may damage the organisms grown. Many of the traditional methods to fight algae are either insufficient, cumbersome, environmentally unfriendly, or all of these. LG Sonic uses ...

  • Creating a Sustainable Food Future: Interim Findings - A menu of solutions to sustainably feed more than 9 billion people by 2050

    The world’s agricultural system faces a great balancing act. To meet different human needs, by 2050 it must simultaneously produce far more food for a population expected to reach about 9.6 billion, provide economic opportunities for the hundreds of millions of rural poor who depend on agriculture for their livelihoods, and reduce environmental impacts, including ecosystem degradation and ...

  • Model of an aquaponic system for minimised water, energy and nitrogen requirements

    Water and nutrient savings can be established by coupling water streams between interacting processes. Wastewater from production processes contains nutrients like nitrogen (N), which can and should be recycled in order to meet future regulatory discharge demands. Optimisation of interacting water systems is a complex task. An effective way of understanding, analysing and optimising such ...

  • Salmon aquaculture could incorporate seaweed and sea urchins to reduce nitrogen enrichment

    Farming fish together with seaweed and other species could help improve the sustainability of aquaculture and reduce pollution. A new study provides a tool for designing sustainable fish farming systems and calculates their potential to recycle waste. An example of a salmon farming system incorporating seaweed and sea urchins could reduce nitrogen releases to the environment by 45%. Over half of ...

  • What does climate change mean for America’s $73 billion angling industry?

    Inland fish play critical roles in North American ecosystems and economics: In the U.S. alone in 2011, freshwater anglers spent more than $30 billion on their hobby, generating $73 billion in economic output. And fish help keep nature in balance as they feed on aquatic plants and animals and in turn provide ...

  • Freshwater ecosystems

    Freshwater ecosystems in Europe are rich in biodiversity and provide essential ecosystem services to humans Europe's freshwater ecosystems range from rivers, flood plains, lakes and ponds, marshes and peatlands, to man-made water bodies such as canals and reservoirs (EC, 2007a; EC, 2007b). They encompass a broad variety of wetlands. These different systems also interact with groundwater. ...

  • Pigs: Montfort Boys Town, Fiji

    Before 1996, Montfort Boy's Town, a school for disadvantaged boys in Suva, Fiji, taught students how to raise both food and funds by farming fish in ponds. In 1996, ZERI and Professor George Chan arrived, proposing a new integrated farming system that would expand their current efforts into FIVE healthy new enterprises by simply gathering the waste generated by a local brewery. These new revenue ...

  • Case study - Boonsawang, Thailand

    While shrimp and prawn production still represent the highest volumes in Thailand, an increasing number of farms started to diversify into other species. Private hatcheries and nurseries now supply the market with weaned fry for species such as barramundi and sea bass. Boonsawang Co. in Chonburi, owned by Suthi Mahalao, also exports fry to Vietnam, Malaysia, Singapore, Taiwan, Australia and ...

  • Effects of androstenedione exposure on fathead minnow (Pimephales promelas) reproduction and embryonic development

    High concentrations (300 ng/L) of androstenedione (A4) were identified in snowmelt runoff from fields fertilized with manure from livestock feeding operations in Wisconsin. In fishes, A4 is an active androgen and substrate for biosynthesis of functional androgens (e.g., testosterone and 11‐ketotestosterone) and estrogens (e.g., estradiol‐1713). Thus, A4 has the potential to be a powerful ...

  • Does one of the world’s most abundant animals need protection from our appetite?

    As demand grows and habitat disappears, scientists ponder tighter controls on the Antarctic krill harvest. Barely longer than your thumb, weighing under an ounce and nearly translucent, delicate crustaceans known as krill are vital to ocean ecosystems around the world. In the waters that encircle Antarctica, krill are an essential food source for penguins, baleen and blue ...

  • Rising Meat Consumption Takes Big Bite out of Grain Harvest

    http://www.earth-policy.org/data_highlights/2011/highlights22 World consumption of animal protein is everywhere on the rise. Meat consumption increased from 44 million tons in 1950 to 284 million tons in 2009, more than doubling annual consumption per person to over 90 pounds. The rise in consumption of milk and eggs is equally dramatic. Wherever incomes rise, so does meat consumption. ...

    Plan B is shaped by what is needed to save civilization, not by what may currently be considered politically feasible. Plan B does not fit within a particular discipline, sector, or set of assumptions. Implementing Plan B means undertaking several actions simultaneously, including eradicating poverty, stabilizing population, and restoring the earth’s natural systems. It also involves cutting ...

  • Shrimp farming: Why prevention is better than medicine

    Disease challenges that have affected a number of key shrimp production regions around the world in recent years have increased the focus on producing healthier and more robust stocks. In addition to establishing very strict sanitary requirements, many shrimp farmers have sought new health-specific diets across the shrimp lifecycle that progress growth and reduce bacterial challenges. Some, ...

  • The number one thing each of us can do to protect biodiversity

    Reducing our consumption of animal products can go a long way toward conserving endangered habitat around the world. Agriculture expansion is the leading driver of natural habitat loss worldwide. However, most of this growth is not to produce vegetables, fruits or grains to be eaten by people. Ecosystems are destroyed overwhelmingly to feed livestock. Livestock production ...
