Currently, 95 of every 100 young wild salmon will die at sea. Only five will return to their native river as adults. This low rate of return occurs throughout wild salmon’s natural range including both Scotland’s east and west coasts. Sea lice from salmon farming is often said to contribute to this high mortality but actually, just one fish out of the 95 will die as a result of sea lice that might have originated from a salmon farm. Wild salmon must contend with much bigger issues whilst at sea than sea lice.
With such high mortality, even for fish from some of Scotland’s most well-known rivers, conservation groups might be expected to be working hard to identify any way of ensuring more fish return to Scottish rivers. Far from it, they have instead focused their ire at the salmon farming industry, even about issues that have no direct relevance to the wild fish they aim to protect.
Salmon farming has received a great deal of media attention, much more than it truly deserves. It is accused of having a negative impact on the marine environment but the reality is that the impact from salmon farming is relatively small and salmon farmers are working continuously to reduce any impacts they have. Salmon farming is no different to any other form of agriculture.
Freshwater fish diversity is harmed as much by selective logging in rainforests as they are by complete deforestation, according to a new study.
Researchers had expected the level of damage would rise depending on the amount of logging and were surprised to discover the impact of removing relatively few trees.
There are many types of logging that occur in rainforests, from 'selective logging' - only taking certain species - to complete logging and the transformation of the rainforest to oil-palm plantations.

The beach in Dakar, Senegal is empty except for a group of singing fishermen, pushing their colorful wooden boat back to shore. The windy weather has kept many on land today – including Mamadou Mbaye, head of Senegal’s fishermen union. He says the sea is depleted of fish because of foreign trawlers, and fishermen often work three straight months in order to make just under USD 20 a day – half of which goes to expenses like gasoline. And here’s no guarantee they’ll catch something. The fish, he adds, started to go away about ten years ago.
While climate change is one issue leading to a depletion of fish stocks in West Africa, foreign industrial fleets – sometimes fishing illegally – come with their trawlers and capture large quantities of fish, leaving fewer fish for local fishermen to catch. One mega-trawler can capture up to 20,000 tons of fish a year, the annual capacity of about 1,700 of the large wooden canoes local West African fishermen use. As a result, West Africa is losing USD 1.3 billion a year. Senegal, one of the countries hardest hit, is losing USD 300 million a year, or 2 percent of its GDP.
Mozambique’s Minister of the Sea, Inland Waters and Fisheries, Agostinho Mondlane, and his visiting counterpart from Madagascar, Gilbert François, want to sign bilateral agreements to combat illegal tuna fishing in their maritime waters, APA can report on Wednesday.The two officials met late on Tuesday in the Mozambican capital, Maputo.
“A Memorandum of Understanding will be signed soon with a view to implementing the understandings reached, within the framework of the talks begun between the two countries”, he told a media briefing late on Tuesday.
Madagascar’s Fisheries Minister said “satellite, radar and port inspections will be used to crack down on illegal fishing in the Indian Ocean, where tuna catches have reached the maximum sustainable limits”, Francois said, adding that port inspections will play an increasingly major role in the crackdown, with authorities checking boats, documents and even cargo.
‘There’s a closure along the south coast for the spawning season, so I decided we’d try our luck off the Westfjords. But it hasn’t been a great trip and cod are thin on the ground these days,’ said Akurey’s skipper Eiríkur Jónsson, who expects to dock in Reykjavík around midday tomorrow.
‘We started the trip on the Mountains and as usual there was plenty of golden redfish, and we had some good hits of saithe. Then we tried the Eldey Bank, but there wasn’t much there. I knew that cod fishing had dropped off deep on the Selvogur Bank, at least outside twelve miles, I decided to try the Westfjords. We haven’t had much success and I expect we’ll have a couple of tows off the Snæfells glacier on the way home,’ he said. When we spoke to him, the trip had resulted in 100 tonnes in the fishroom.
A Ministry for Primary Industries (MPI) operation that was recently concluded with the assistance of police, has resulted in a group of Wellington divers facing charges for gathering excess paua and offering to sell it on the black market.
The operation targeted a group of people who had been diving in isolated areas around Wellington's south coast that are mainly accessible only by way of specifically equipped 4x4 vehicles.
MPI team manager (fisheries) for the eastern and lower North Island, Mike Green, says the operation concluded after MPI fishery officers went to an area on the capital's south coast to inspect the activities of 2 divers.
Tinned tuna zinc could harm bowel metabolism United States
New research carried out by Binghamton University, New York, suggests that tinned tuna contains up to 100 times more zinc than is safe, which could seriously affect people's bowel nutrient absorption.
