Empowering consumers to make informed choices In the information age, making informed decisions should be straightforward. Consumers need information about sustainability and nutrient values, as well as provenance, and potential risks and benefits of the products they consume. However, when it comes to seafood consumption, the complexities of health benefits, sustainability, and climate impacts ...

Fish pond anti-seepage geomembrane is one of the used geotechnical materials for small family fish farming, ornamental fish ponds, and large fish pond liners. The reasons for using this material are as follows: First, the cost of the anti-seepage geomembrane material is much lower than that of concrete; the second is that the construction of the anti-seepage geomembrane material is more ...
pH affects the toxicity of substances in water. A typical pH-drop leads to a two- to threefold increase in the level of toxic free CO2, initiates the formation of H2S, and increases the toxicity of several metals, including copper (Cu2+). Conversely, an increase in pH-value will raise the concentration of unionized ammonia (NH3), which is also toxic to fish. Therefore, regulation of alkalinity ...
Fish farming a profitable business in Nigeria, let’s now proceed to decide which specie of fish we want to farm. Below are some of the most popular fish species that is suitable for Aquaculture. 1. Catfish Even though Catfish is not the most popular fish in Nigeria, this fish species is by far the most cultivated in Nigeria. One thing good about catfish is that it is one of the easiest fish ...
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 ...
Six years ago, the Norwegian coast guard filmed a Scottish fishing vessel riding gray swells, dumping 5 metric tons of dead fish back into the North Sea. Over the European Union catch quota, and so unable to keep all the fish they’d caught, the fishermen had to ditch some. To the Norwegians, who aren’t part of the EU and hold a strict discards ban, the waste was shocking. When this ...

Understanding variability of contaminant bioaccumulation within and among fish populations is critical for distinguishing between the chemical and biological mechanisms that contribute to food web biomagnification and quantifying contaminant exposure risks in aquatic ecosystems. The present study examined the relative contributions of chemical hydrophobicity (KOW) and habitat use as factors ...
Endocrine‐disrupting chemicals are known to alter the fitness of individual organisms via changes in growth, behavior, and reproduction. It is largely unknown, however, whether these effects cascade through the food web and indirectly affect other, less sensitive organisms. The authors present results from a mesocosm experiment whereby the effects of the synthetic estrogen 17α‐ethinylestradiol ...
Gamma‐aminobutyric acid (GABA) and GABA receptors play an important role in neuroendocrine regulation in fish. Disruption of the GABAergic system by environmental contaminants could interfere with normal regulation of the hypothalamic‐pituitary‐gonadal axis, leading to impaired fish reproduction. The present study used a 21‐d fathead minnow (Pimephales promelas) reproduction assay to ...
This study was conducted during 2006–2010 on River Swat, North of Pakistan. River Swat is the largest tributary of the Kabul River, which ultimately joins the Indus River. Fishing is a regular activity on the entire River Swat and is a major source of recreation and livelihood. This activity caused a decline in fish populations and ultimately fishing has been banned since 1982. This study ...
As government leaders prepare for next month’s UN Conference on Sustainable Development (Rio+20) in Brazil, one issue is conspicuously absent from the agenda: land rights. Strong property rights—the rights for people to access, control, transfer, and exclude others from land and natural resources—create incentives to invest in sound land management and help protect land from ...
Changes in the Small Pelagic Fish (SPF) densities and distribution during ENSO 1997?1998 were found from observations made between 1994 and 2001 along the northwestern coast of Baja California, Mexico. Results showed that temperature and variables associated with the surface mixing processes had an effect on the SPF shoal behaviour and distribution. Between September and December 1997, acoustic ...
The Southern Bluefin Tuna cases offer a rare judicial pronouncement on the application of the Precautionary Principle in marine conservation. Specifically, the 1999 application for provisional measures to the International Tribunal for the Law of the Sea (ITLOS), initiated by Australia and New Zealand to limit a unilateral Japanese experimental fishing programme, yielded reasoned judicial ...
