Adsorption isotherm of uranyl ions by scales of Corvina fish
Fish scale is a by-product of fishery. The scales are mainly formed by hydroxyapatite and collagen, forming a kind of natural composite with a large specific surface area that intensifies the adsorption process. In this paper, the potential of adsorption of scales of Corvina fish for uranyl ions from nitric solutions was studied. Equilibrium and kinetic studies in adsorption of uranyl ions in ...

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 ...

Taxpayer dollars subsidizing destruction
One way to correct market failures is tax shifting—raising taxes on activities that harm the environment so that their prices begin to reflect their true cost and offsetting this with a reduction in income taxes. A complimentary way to achieve this goal is subsidy shifting. Each year the world's taxpayers provide at least $700 billion in subsidies for environmentally destructive activities, such ...

The Role of Mangroves in Fisheries Enhancement
In 2011 humans caught and consumed 78.9 million tonnes of fish, crustaceans, molluscs and other species groups from the world’s oceans, accounting for 16.6% of the world’s animal protein intake (FAO 2012). This is projected to increase further, to over 93 million tonnes by 2030 (World Bank 2013). Global demand for fish products has increased dramatically over recent decades. Fishing ...

Prevent Fish Kill in the Spring
Pond Deicing Can Help Prevent Fish Kill Keeping the pond open will help keep oxygen in the water, attract water fowl and help prevent fish kills in the spring. The most common cause of fish kills is suffocation due to lack of dissolved oxygen. Most dissolved oxygen is produced by algae and aquatic plants through photosynthesis. A lesser but also important source of oxygen in water is diffusion ...

Moving Up the Food Chain
For most of the time that human beings have walked the earth, we lived as hunter-gatherers. The share of the human diet that came from hunting versus gathering varied with geographic location, hunting skills, and the season of the year. During the northern hemisphere winter, for instance, when there was little food to gather, people there depended heavily on hunting for survival. Our long history ...

Expanding marine protected areas to restore fisheries
After World War II, accelerating population growth and steadily rising incomes drove the demand for seafood upward at a record pace. At the same time, advances in fishing technologies, including huge refrigerated processing ships that enabled trawlers to exploit distant oceans, enabled fishers to respond to the growing world demand. In response, the oceanic fish catch climbed from 19 million tons ...
