For decades researchers have recorded sounds from whales and other marine mammals, using a variety of methods including passive acoustic monitoring (PAM) to better understand how these animals use sound to interact with each other and with the environment. Now, for the first time, researchers report using this technology to record spawning cod in the wild. Acoustic behavior in cod has been of interest for several decades, but few studies have observed their use of sound as part of...

A new investigation put in evidence the key role of cod as regulator of the whole Baltic Sea ecosystem. The study shows that when the cod population in the central Baltic increases, it spreads into larger areas and spills over into adjacent marginal systems where it usually does not occur, as for example the Gulf of Riga. On the other hand, when the cod population size in the central Baltic decreases, it concentrates into the southern Baltic Sea and disappears from the other systems where...
Hake is constantly fished in the waters of the European Atlantic Ocean and, nevertheless, resists stock depletion relatively well. At times nature is capable of correcting the mistakes made by humans. Ms Nerea Goikoetxea, a researcher at Azti-Tecnalia, has been witness to this. She has investigated the population dynamics of the northern European hake population, observing which environment has favored the species since the 90s to date: the sea has turned milder, and so larvae have grown...
Less expensive species are labeled and sold as cod while environmental impact of purchases is concealed by product labels28% of cod products in Ireland are mislabelled, as compared to 7% in the UK, according to research published today in the journal Fish and Fisheries.This is the first time that researchers have compared the labelling of cod products sold in Ireland and the UK. Both countries operate under the same EU policies for seafood traceability and labelling.Using a DNA barcoding...
Despite a 30-year warming trend, the last three years in the Bering Sea have been the coldest on record. A University of Alaska Fairbanks scientist says that the cold temperatures have helped produce larger zooplankton in the Bering Sea, which may be changing the way Walleye pollock are feeding.Alexei Pinchuk, research professional at the UAF Seward Marine Center, has spent the last three years gathering zooplankton samples in the Bering Sea. He and his colleagues have been looking at how...
The UK trawl fishing fleet has to work 17 times harder to catch the same amount of fish today as it did when most of its boats were powered by sail, according to new research.Researchers from the University of York and the Marine Conservation Society (MCS) used UK Government data on the amount of fish caught and the size and number of boats involved "“ the fleet's fishing power "“ to analyze the change in fish stocks since 1889. They found that trawl fish landings peaked in 1937, 14 times...

Many types of fish have been given the common name Whiting. The fish originally known by that name in English is Merlangius merlangus, in the family Gadidae. In the USA it is known as the English Whiting. In the USA, the name Whiting on its own is often used for various species of Hake, genus Merluccius. In Canada, it is used for the Alaska pollock Theragra chalcogramma. Like the true Whitings, these are all members of the order Gadiformes. In India and Australia, the name Whiting (though...
The Haddock or Offshore Hake is a marine fish distributed on both sides of the North Atlantic. Haddock is a popular food fish, widely fished commercially.
