Fish as feed inputs for aquaculture: practices, sustainability and implications

Status and trends on the use of small pelagic fish species in Chile 309


cultivated fish (mainly Atlantic salmon (Salmo salar) and rainbow trout (Oncorhynchus
mykiss)), 35 percent corresponds to pelagic fish (anchoveta, jack mackerel, South Pacific
hake and sardine) and the remaining 10 percent is comprised of other fish (Figure 19).
In 2005, 78 percent (116 000 tonnes) of frozen pelagic fish
products was made from jack mackerel, 16 percent South Pacific hake
(23 000 tonnes) and 5 percent chub mackerel (7.6 thousand tonnes), with anchoveta and
sardines together contributing only 1 percent (Table 12 and Figure 20).
Pelagic fish that are traditionally destined to the reduction industry have made a
significant contribution to the growth in the production of frozen products. Over the
period 1995–2005, their contribution has increased by around 700 percent, rising from
a total of 21 thousand tonnes in 1995 to 147 thousand tonnes in 2005. The greatest


contribution to growth is provided by jack mackerel, chub mackerel and South Pacific
hake, with an average increase during this period of almost 1 157 percent. Nevertheless,
the production of frozen product from smaller pelagic fish (anchoveta and sardines)
has decreased by an average of around 87 percent (Table 12 and Figure 21).
