Oily fish seafloor, whereas oily fish are pelagic, living in the water column away from the bottom.

For this reason the consumption of oily fish rather than white fish can be more beneficial to humans, particularly concerning cardiovascular diseases; however, oily fish are known to carry higher levels of contaminants (such as mercury or dioxin) than whitefish. Among other benefits, studies suggest that the omega-3 fatty acids in oily fish may
