River Irwell suffers serious pollution for the second time in three weeks

The River Irwell appears to have been polluted for a second time in three weeks. Countless fish and insects died following reports a pesticide which was poured down a drain and devastated a 25-mile stretch of the river from Rawtenstall into Manchester city centre earlier this month. Now a second incident has been reported on a section of the Irwell north of Bury. The incident has been reported to the Environment Agency. Mike Duddy, chief executive of the Mersey Basin Rivers Trust, said virtually no river life had survived the previous incident.

Three rivers in the Cameron Highlands declared 'dead'

Regional Environment Awareness Cameron Highlands (REACH) president Ramakrishnan Ramasamy said most rivers in the highland, known for its tourism and agriculture, are heavily polluted. He said data from the Department of Environment (DoE) and the Drainage and Irrigation Department (DID) showed that only about 10 per cent of 123 rivers were in Class I and Class II, while the remainder were in Class III and Class IV. He also said three rivers had been declared biologically dead, and came under Class V of the classification.

Pesticide Impact on Bay Delta Fish Could Be Greater Than Realized

New monitoring in the Bay Delta shows that the water is a soup of urban and agricultural insecticides, herbicides and fungicides. When combined, pesticides at sublethal levels can have deadly synergistic effects on fish. “The Sacramento River and San Joaquin River have been monitored for years, but historically there has been little monitoring in the Delta itself,” says Michelle Hladik, an environmental chemist who leads the USGS Pesticide Fate Research Group.

Salmon slump on River Tweed

SALMON catches on River Tweed and its tributaries fell by seven per cent last year. A total of 7,680 fish were taken by rod and line during the 2016 season - down from 8,091 in 2015 – reflecting a year-on-year downward trend since 2013 when over 14,000 salmon were caught. There was an even sharper fall in the number of sea trout taken by anglers in 2016 – from 1,280 to 2,323 – the lowest catch in the past decade.

Declining salmon stocks on River Teifi sparks concern

CORACLE fishermen on the River Teifi have reacted immediately to concerns about the falling levels of fish stocks by agreeing to return any salmon they catch. The Teifi Coracle Netsmen has also called on other anglers to adopt a catch and release policy after shock new figures from Natural Resources Wales (NRW) showed a sharp decline in the number of fish caught. There was just over 40 declared net catches of salmon on the river in 2015 compared to about 115 in 2014. Declared rod catches were down from 300 in 2014 to just over 200 in 2015.

Fish stocks in the Mediterranean Sea are deteriorating at an alarming rate

A recent analysis by the European Commission's Joint Research Centre (JRC) shows that 93% of the assessed fish stocks are overexploited, and a number of them are on the verge of depletion. In addition, the Mediterranean Sea has lost 41% of its marine mammals and 34% of the total fish population over the past 50 years. An estimated 10 000 to 12 000 marine species inhabit the Mediterranean Sea, but this extraordinary biodiversity is in grave danger. Further delays in concerted action could result in irreversible damage and a collapse of key stocks that are essential to the fisheries sector.

Worry over fish and wildlife decline in B.C.

The B.C. Wildlife Federation is concerned about declining fish and wildlife populations – and is calling on the province to do something about it. The BCWF is kicking off a series of town halls across the province to discuss the matter. It's also urging people to sign a petition calling on government to dedicate all hunting licence and fee revenues directly to wildlife management. "B.C. is one of the most biodiverse jurisdictions in the world, yet one of the most under-funded fish and wildlife management jurisdictions," the group says. According to the federation, B.C.

Cod fish numbers decline greatly in the Gulf of Maine

Massachusetts scientists say they have reached the same conclusions as their federal counterparts in a study about the poor status of cod fish in the Gulf of Maine. The Boston Globe ( ) reports the scientists found the region's cod are at a historic low of about 80 percent less than the population from a decade ago. Micah Dean oversaw the survey for the Massachusetts Division of Marine Fisheries. He says he hopes fishermen who doubted federal government's science on the issue will find the results credible.

Der jurassische Grenzfluss Doubs ist in noch schlechterem Zustand als bekannt

Der durch idyllische Landschaften weitab von Paris und Bern fliessende Doubs leidet seit Jahrzehnten an Verschmutzungen durch Bauern und Abwasserreinigungsanlagen (ARA) sowie Übernutzung durch die Energiewirtschaft. Akut vom Aussterben bedroht ist darum die lokale Fischart Roi du Doubs; ein Aktionsplan von 2015 soll diesen retten. Im Jahr davor hatten Pro Natura, der WWF und der Schweizerische Fischereiverband (SFV) biologisch-chemische Gutachten über die Wasserqualität in Auftrag gegeben. Deren Ergebnisse liegen nun vor, wie die Organisationen am Donnerstag, 30. März 2017, mitteilten.

Berufsfischer fangen weniger Felchen

Mit rund 135 Tonnen Fisch haben die Berufsfischer am Untersee und Rhein im Jahr 2016 rund 4,5 Tonnen weniger gefangen als 2015. Der Rückgang beim Gesamtfang gegenüber dem Vorjahr liege vor allem am Einbruch bei den Felchenfängen, erklärte Werner Keller, der zweite Vorsitzende des Fischereivereins Untersee und Rhein, bei der Hauptversammlung im Hotel-Restaurant Mohren auf der Insel Reichenau. Vom sogenannten Brotfisch, der zwei Drittel des Gesamtfangs ausmacht, wurden 2015 knapp 100 Tonnen gefangen, im Jahr 2016 aber nur rund 88 200 Kilo – ein Rückgang von über elf Prozent.
