Typical agriculture sectors like animal production and processing, aquaculture and its processing, and fruit and vegetable processing, can be water-intensive and generate complex and sometimes severe pollution. Controlling pollution hinges on knowing its quantity (wastewater and solid waste volume) and characteristics (major pollutants and their concentration range, nature of wastes, …
Movement of nutrients across ecosystem boundaries can have important effects on food webs and population dynamics. An example from the North Pacific Rim is the connection between productive marine ecosystems and freshwaters driven by annual spawning migrations of Pacific salmon (Oncorhynchus spp). While a growing body of research has highlighted …
Rotational harvesting is one of the oldest management strategies applied to terrestrial and marine natural resources, with crop rotations dating back to the time of the Roman Empire. The efficacy of this strategy for sessile marine species is of considerable interest given that these resources are vital to underpin food …
The smallest and rarest marine dolphin in the world could be extinct within 15 years if protection is not stepped up, new research suggests. Conservationists say the remaining population of Maui's dolphins has dropped below 50. The critically endangered species is found only in waters off New Zealand. Measures to …
Peru is bracing for a moderate El Nino weather event in coming months, with warming sea temperatures threatening to set the stage for another disastrous year for anchovy fishing and fishmeal exports. Enfen, the Peruvian bureau tasked with forecasting el Nino, put policymakers on alert and said a "moderate" El …
One of the world's iconic freshwater fish, the giant humpback Mahseer found in India, is on the brink of extinction, thanks to a conservation programme that has backfired, according to scientists. In fact, the humpback Mahseer which lacks a valid scientific name could potentially go extinct before being named, the …
The Western Ghats region of India is an area of exceptional freshwater biodiversity and endemism. Mahseer of the genus Tor are considered prized sport fishes of great cultural significance; nevertheless, they are threatened as a result of increasing anthropogenic stressors. In the River Cauvery, the mahseer community comprises a ‘blue-finned’ …
NAGPUR: Taking cognizance of the alarming decline in the population of Mahseer, an endangered fish species, Tata Power, India's largest integrated power company, has supplied 10,000 healthy Mahseer fingerlings to Hira Bambai reservoir near Nagpur. The company has set up a breeding centre at Walwan Gardens, Lonavala, as part of …
With as few as about a dozen of the mammals left, federal regulators say a unique species of baleen whales in the Gulf of Mexico about 70 miles off the Florida Panhandle may be threatened with extinction and could get special protection from federal regulators. In April, the National Marine …
For the last decade, scientists have deployed increasingly capable underwater robots to map and monitor pockets of the ocean to track the health of fisheries, and survey marine habitats and species. In general, such robots are effective at carrying out low-level tasks, specifically assigned to them by human engineers — …
Climate change and consequent warming of the oceans poses multiple threats to fisheries sector, said Vice-Chancellor of Kerala University of Fisheries and Ocean Studies B. Madhusoodana Kurup at a technical session on the impact of global warming on fisheries and aquaculture at the International Conference on Global Warming and Food …
Residents of the tiny village of Fanalei in the Solomon Islands killed more than 1,600 dolphins in 2013 for their teeth, a local currency and popular adornment, researchers said. The overall recorded tally from 1976-2013 was more than 15,400, according to research published in the journal Royal Society Open Science. …
Port Harcourt — Pastor Christian Lekova Kpanddei wears his camera like a weapon, slung over a T-shirt telling oil giant Shell to "Own Up. Pay Up. Clean Up". He was a fish-farmer in the Ogoniland town of Bodo, in the oil-rich Niger Delta, before a rusty 55-year-old pipeline owned by …
A new study may reveal an unprecedented surge in biodiversity that occurred 20 million years ago. Researchers have discovered that species migrations across the Isthmus of Panama began during this time period, which is six times earlier than commonly assumed. "Even organisms that need very specific conditions to survive, such …
The commercial value of the Earth's oceans currently measures up to the world's leading economies. However, a new report indicates that wealth is rapidly decreasing - and it's up to humanity to avoid the destruction of the ocean environment. 'Reviving the Ocean Economy: The case for action - 2015' is …
According to the IPCC’s Fifth Assessment Report, changes in the climate over the last 30 years have already reduced global agricultural production by 1 – 5 % per decade relative to a baseline without climate change. In addition, recent studies indicate that even a 2 degrees increase in global temperature …
Decision to scrap habitat conservation plans sparks outrage as regulators and water contractors push forward with multi-billion dollar engineering project For the past eight years, California politicians, utility companies, farmers and environmentalists have been arguing over the Bay Delta Conservation Plan (BDCP). Environmental groups are now speaking out after recent …
OSLO – Economic output by the world’s oceans is worth $2.5 trillion a year, rivaling nations such as Britain or Brazil, but marine wealth is sinking fast because of overfishing, pollution and climate change, a study said on Thursday. “The deterioration of the oceans has never been so fast as …
As if climate change and pollution weren’t bad enough, overfishing is making a mess of the Great Barrier Reef, the latest research from James Cook University in Queensland, Australia, published Tuesday, has found. Researchers discovered that the removal of certain predatory species like coral trout and snapper from the food …
The monetary value of the world’s oceans has been estimated at US$24tn in a new report that warns that overfishing, pollution and climate change are putting an unprecedented strain upon marine ecosystems. The report, commissioned by WWF, states the asset value of oceans is $24tn and values the annual “goods …
Removing species such as coral trout and snapper weakens the Great Barrier Reef’s ecosystem and resilience, a new James Cook University study finds Commercial and recreational fishing is imposing a toll on the Great Barrier Reef’s food chain, researchers say. A study produced at James Cook University has found removing …
