[edit] Conservation
Skates have slow growth rates and, since they mature late, low reproductive rates. As a result skates are vulnerable to overfishing and it appears that skates have been overfished and are suffering reduced population levels in many parts of the world. The barndoor skate, Raja laevis, is currently listed with the IUCN as vulnerable due to being severely overfished.[2] However, population data are lacking to determine the exploitation of the big skate at this time.[citation needed]
In 2010, Greenpeace International has added the barndoor skate, bottlenose skate, spotback skate, and maltese skate to its seafood red list. "The Greenpeace International seafood red list is a list of fish that are commonly sold in supermarkets around the world, and which have a very high risk of being sourced from unsustainable fisheries."[3]
