Overfishing (as in the rate of depletion) at the Cross seamount appeared to be quite high, causing concerns.
Overfishing occurs in some areas, and the resource is managed by some governments.
The Marine Conservation Society has rated the scabbardfish as a species vulnerable to overfishing.
They continue to be of interest as game fish, and are among the most common types landed by boat anglers; in fact, there is evidence of overfishing in Monterey Bay and southern California.
The International Union for Conservation of Nature (IUCN) has assessed the Caribbean reef shark as Near Threatened; its population has declined off Belize and Cuba from overfishing and exploitation continues in other regions.
Anadromous fish such as Coho salmon and steelhead are found in local streams but are threatened by overfishing and habitat destruction caused by logging practices.
The International Union for Conservation of Nature has assessed this species as of Least Concern, while noting that local stocks may easily become overfished because of the shark's slow growth and limited migratory habits.
"Tridacna costata may be the earliest example of marine overexploitation," said researcher Claudio Richter, a marine ecologist at the Alfred Wegener Institute for Polar and Marine Research in Bremerhaven, Germany.
