The direct threat from the killer warty comb jellyfish to the Baltic cod population has been shown not to be so serious after all. Even though the invasive killer jelly feeds constantly, cod eggs seem not to be on the menu. In fact, if they accidentally swallow an egg, they even throw it up again.
Eel stocks are currently undergoing a steep decline, although no one knows exactly why. This is why researchers from a number of institutions including DTU Aqua are in the process of examining the European eel’s (
Anguilla anguilla) behaviour in order to understand what happens during its reproductive migration from Europe to the Sargasso Sea. The studies are part of the EU financed project EELIAD (

The oceanic life of eel is still a mystery. New findings from the Danish Galathea 3 Expedition to the Sargasso Sea now shed light on the conditions for larval growth and feeding and point to an alternative route for larval drift towards Europe
The reproduction of eels in captivity has become an important research focus due to the severe decline of the natural stocks. Leading scientists from European research institutes and the aquaculture industry are determined to reproduce the European eel in captivity. The result is a € 5 mill research project: PRO-EEL, coordinated by DTU and supported financially by the European Commission.
The Danish research vessel Dana and a group of scientist from Denmark and abroad are in Greenland to study the impact of climate changes. In turn, the scientists will write home about their work onboard.
DTU Aqua has received a grant of DKK 5.6 million from The Danish Centre for Marine Research to conduct comprehensive climate change surveys in Greenland with Denmarks largest marine research vessel Dana.
Researchers at DTU Aqua have developed a method that can document fishery electronically. Public authorities as well as environmental organizations and fishermen consider the method as a good tool for developing sustainable fisheries, says the profile magazine of the Technical University of Denmark , DTU in Profile
The world’s strongest animal, the copepod, is barely 1 mm long.It shows that copepods – in relation to their size – are more than 10 times as strong as has been previously documented for any other animal.
The seafood Spoilage and Safetcy Predictor is available in version 3.1. The free software helps producers of seafood to prevent unacceptable growth of human pathogenic bacteria.
Scientist from the EU-funded EELIAD project has by attaching pop up satellite tags (PSAT) to eels, revealed the first stage of the European eels mysterious migration to the Sargasso Sea. The results are published this week in Science.
Staff from The National Institute of Aquatic Resources (DTU Aqua) in Denmark will be at DanFish International 2009 to present and discuss the results of a recently completed project on electronic monitoring. The final report is online now.
The world’s fastest ambush has been caught on film. Behind the attack is a copepod which must be ‘faster than its shadow’ to capture its prey in water thicker than syrup.
The rate of evolution due to natural selection is generally so slow that the consequences only become apparent over tens of thousands of years. However if the selection pressure is strong and acts on a trait that has high heritability then changes may occur much more rapidly, as shown by the success of selective breeding programmes in agriculture.
Bluefin tuna disappeared from Danish waters in the 1960s. Now the species could become depleted throughout the northeast Atlantic and Mediterranean, according to analyses by the Technical University of Denmark (DTU Aqua) and University of New Hampshire. The species is highly valued as sushi.

From 1 January 2008 the Danish Institute for Fisheries Research has changed its name to DTU Aqua, National Institute of Aquatic Resources.
Scientists studying ancient fish bones in Scandinavia have discovered that warm-water species like anchovies and black sea bream once thrived in Danish waters during a prehistoric warm period and are now returning. Some cold-water species, such as cod, were also abundant during this period, having benefited from a lower fishing effort.
A new folder gives a brief description of the multi-disciplinary IMPSEL Project (IMPlementation of SELective and sustainable fisheries) and presents the main points from the study.
Researchers at The Danish Institute for Fisheries Research, Technical University of Denmark have succeeded in producing viable eggs and cultured larvae of captive European eel for up to 12 days. During this period, the larvae completed the critical period, where they completely rely on the nutrition from the egg and reached the stage where they are ready to start feeding. The result is a breakthrough, because reproduction of eels in
captivity has proven difficult. The results were presented in October at a conference held by The European Aquaculture Society. The long term goal is to produce glass eels for self-sustaining aquaculture and thereby help the endangered European eel.
The idea that small swimming organism could change the circulation in the oceans is intuitively appealing. And yet the conclusion in a newly published Science article is no: Their movements do not cause enough mixing to alter the ocean's circulation.
Danish eel researchers recently succeeded in beating the world record by keeping larvae of the European eel alive for five days.
The Department for Seafood Research at DIFRES has recently held a successful seminar on the control of Listeria monocytogenes in the seafood industry.
DIFRES research group calculate relation that make the counting of fish in the oceans easier.
