Looking at decades of data from the Gulf of Maine, researchers found that between the 1970s and 2000s, human fishing practices altered mercury levels in Atlantic cod and spiny dogfish
. Meanwhile, rising water temperatures caused mercury levels in Atlantic bluefin tuna to increase by an estimated 56%.
These spiny dogfish
are a threatened species after years of over-fishing and, although they are abundant in a few areas, schemes such as the Scottish Shark Tagging Programme and the Luce Bay Tagathon are required to track the health of the population.
Almost 60% of these animals were either lesser spotted dogfish, spotted ratfish or spiny dogfish
In the UK the spiny dogfish
, which is in the shark family and classed as vulnerable, is sold in chip shops under the more appetising name of rock salmon.
And overfish the spiny dogfish
to the extent their survival as a species is severely compromised?
Desert Island Biological Laboratory in Maine studying the physiology of spiny dogfish
Abstract--Recently, it has been suggested that spiny dogfish
(Squalus acanthias) in the western North Atlantic Ocean have a shorter gestation period than the widely cited 2 years, have an asynchronous reproductive cycle, and carry pups in various stages of development.
When prepared as food, the spiny dogfish
is given what name?
There are no recreational restrictions for Spiny Dogfish

Those characteristically from shelf break area, usually included in the incidental captures, were the argentine goatfish (Mullus argentinae), grey triggerfish (Balistes capriscus), whitemouth croaker (Micropogonias furnieri), flounders (Paralichthys spp.), spiny dogfish
