P. chilensis is a generalist predator, its diet consisting mainly of
crustaceans, with smaller quantities of fish and
polycheate worms; less often eaten are
molluscs,
brittle stars,
sea urchins,
proboscis worms,
peanut worms,
spoon worms and
tunicates. Small fish (less than long) fed largely of the amphipod
Ampelisca araucana while medium size fish mostly took
mysids such as
Neomysis sp. The largest fish (over long) mostly preyed on other species of fish, worms, molluscs and sea urchins. The diet also varies according to the time of year and the seasonal availability of prey species, with more fish being taken in the autumn. This fish is
oviparous, with spawning taking place in the spring. ==References==
