1) Reduced availability and capture of anchoveta
Off the coast of Peru, the catchability of Peruvian anchoveta
(Engraulis ringens) changed as vulnerability increased because of high densities coupled with improved detection ability through sonar and radar (Bertrand et al.

Catches of anchoveta
and herring were approx imately 18,000 t in 1964, increasing to 77,000 t by 1973.
For example, the Peruvian anchoveta
is the world's largest single-species fishery.
In addition to herring that is used for fishmeal production, other poorly consumed small fish species can be used, such as anchoveta
and European sprat, or the muscle-rich backbones that are left over when fish are filleted.
Increased farming of large predators, such as salmon and tuna, has led to overfishing of prey fish, including anchoveta
and herring, which commonly are used as fishmeal.

This cold mass of water flows from Antarctica to the equator, bringing with it large schools of fish called anchoveta
To maximize growth and enhance flavor, aquaculture farms use large quantities of fishmeal and fish oil made from less valuable wild-caught species, including anchoveta
Then in 10 minutes we see striped marlin attacking swirling shoals of sardines, followed by young tuna fish and a sei whale; a moving tornado of mackerel being slaughtered by spotted dolphin and sailfish and a stunning pirouette of anchoveta
being dive-bombed by Cory shearwaters.
These products are produced from small pelagic (open sea) fish species including Peruvian anchoveta
, Icelandic herring, menhaden from the Gulf of Mexico, Norwegian capelin, and sand eels from the North Sea.
