Sturgeon reappears in Baltic after century absence
A fisherman trawling off the Swedish island of Oeland netted a sturgeon from a species which had disappeared from the Baltic Sea a century ago, news agency TT reported Tuesday.
Fisherman Ulf Aakerlund was at first stumped when he found the 78-centimeter (two-and-a-half-foot) fish in his nets last week.
“Initially I had no idea what it was. But when we looked it up on the Internet and looked in a few books we realised it was a sturgeon,” he told TT.
The specimen was an Atlantic sturgeon, or Acipenser oxyrhynchus, which was thought to have been extinct in the Baltic Sea since the early 1900s due to overfishing.
But according to fish expert Mikael Svensson of the Swedish Species Information Centre, efforts have in recent years been made in Poland to breed sturgeon, and the specimen may have come from there.
“This is a good sign. It would be great if we could have this species in Swedish waters again. The sturgeon is a very special fish that doesn’t resemble anything else we have in our waters,” Svensson told TT.
Atlantic sturgeon can grow as big as 4.5 meters (15 feet) and weigh 360 kilograms (795 pounds).
The species is rare in European waters but is more common off North America’s eastern coast.
Large freshwater fish started disappearing in medieval times, sending fishers to sea: here.
Atlantic sturgeon in the North Sea: here.
Progress in protecting the Baltic Sea is slow, a report from Oceana has found, with many businesses carrying on as usual inside so-called protected areas. The report shows that over 30 percent of the Marine Protected Areas in the Baltic are safeguarded only on paper: here.

Entire fish species disappearing from M’sian waters
By SIRA HABIBU
GEORGETOWN: More than 80 types of fish have either become extinct or gone missing from local waters, said Sahabat Alam Malaysia president S. M. Mohd Idris.
These include various varieties of yu, pari, gelama, pelata, bagok, semilang and kurau.
Describing the situation as alarming, Mohd Idris said it was high time the authorities implemented preventive measures to safeguard the fisheries sector.
“Our fisheries sector is in crisis because of the lack of effective policies and laws on the conservation of marine resources, as well as a lack of enforcement of existing laws,” he said at the National Fisheries Dialogue here Tuesday.
Mohd Idris said the dialogue was organised by Sahabat Alam Malaysia to identify weaknesses in policies and practices, and to suggest ideas for sustainable and effective management of fisheries resources.
“The other objective is to advocate strong and sustainable fisheries policies that emphasise the interdependency of ecosystems and communities,” he said.
“The authorities must also take measures to check the destruction of marine life habitats. There must be a concerted effort to protect mangrove forests, sea grass and coral reefs,” he said.
He said that the impact of modern fishery practices must also be looked into, and added that there was no long-term policy to protect the coastal ecosystem.
“Extinction, over-exploitation and the depletion of fisheries resources must be addressed in the fourth Malaysian Fisheries Policy that is currently being formulated.
“Draft copies of the policy should be made available to the public, and a platform must be given for groups to give feedback and highlight concerns,” he added.
