IN BRIEF - We could eat 90% of the fish we feed other fish
Saturday, February 18, 2017
There’s a reason why fish is fed other fish. You know how people say fish is good for you because it contains healthy fats such as omega 3? Well, most fish we eat today comes from aquaculture, and aquaculture fish doesn’t really have the oils we’re looking for. That’s why these cultured creatures are often fed other, wild fish — especially anchovy, menhaden or herring that nobody is clamoring for, anyway. It’s truly ironic and backward, isn’t it? We want to eat fish because it has good stuff, but the fish we eat doesn’t have good stuff. So we feed the fish with the good stuff to the fish without the good stuff so we can get the good stuff. So why aren’t we doing this directly?
Well, many growers will tell you that that’s not really possible, mostly for economic reasons. People don’t want to buy that kind of fish, there just isn’t a market for it. Well, this new study published on Monday in the journal Fish and Fisheries claims differently.
They found that out of the 20 million tons of fish destined for fishmeal production each year, 70% is destined for other fish to eat. The rest is fed to pig and chicken to speed growth and encourage the development of some nutrient. But this isn’t really necessary, and it adds a lot of unneeded pressure on already diminishing stocks. Furthermore, while many Americans often prefer shrimp and salmon, global preferences are quite different. Tilapia and carp top the preference list in China, for instance.

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.
