Climate is commonly defined as the weather averaged over a period of time. The periode of time is ranging from months to years or even longer time scales. Climate encompasses the statistics of temperature, humidity and wind. Ocean climate consists of average environmental components occuring over a long periode of time. Temperature, salinity and current.read more
Sea lice are the most common parasite on farmed salmon, and the biggest health issue for the industry. For a number of years, oral and bath treatments have been used to combat sea lice. Our monitoring of sea lice shows that their numbers are increasing noticeably, and that in some cases they are developing resistance to the favoured treatment. Sea lice belong to the copepod family, and are found naturally throughout the northern hemisphere.read more
Mackerel is a pelagic and fast swimming fish species. It is distributed in the Northeast Atlantic from the Northwestern part of Africa north to the Barents Sea, and westwards in the Norwegian Sea to Iceland and Jan Mayen. Mackerel also enters the Baltic Sea, and furthermore exists in the Mediterranean Sea and Black Sea.read more
While sending the video-platform Chimaera towards the bottom of the Barents Sea (250–300 m), we see a large amount of particles swirling through the water like snow. The large particles are observed from tenfold of meters above the seabed and down to the seafloor.read more
MAREANO's first cruise of 2015 set sail from Tromsø last Friday bound for the new Norwegian area of the Barents Sea. Sixteen scientists and technicians will spend the next two weeks onboard the research vessel G.O. Sars, investigating one of the world's richest seas. The benthic environment and faunal communities over an area of 12 000 km2 is to be sampled while a total of 44 line kilometers across 60 sites will be filmed with high resolution video.read more
The UN General Assembly has listed seamounts among marine habitat that may have particularly vulnerable benthic communities and fisheries resources. The recent cruise of the RV “Dr. Fridtjof Nansen”, from the 15. Jan to the 12. Feb 2015 aimed at mapping the occurrence and abundance of benthopelagic fish and sessile epibenthos in the southeast Atlantic.read more
For the first time, researchers have investigated how Atlantic cod behaves after catch-and-release. Their study shows that cod recover quickly if they get fished in shallow water, are handled properly and released immediately after capture.read more
In focus: European lobster
The European lobster has been found from the Mediterranean Sea to Northern Norway and west to the Shetland Island and western Ireland. It is usually found in shallow waters less than 40 m deep, where it is night active and shelter in burrows during daytime.
Their preferred habitat is moderately exposed areas with a complex bottom substrate of a mixture of sand and rocks. The lobster has a wide diet, hunting live prey and scavenging on dead organisms.
