Exotic plus native: findings in an unscheduled fish duoculture

ABSTRACT The development of native fish aquaculture represents an important alternative to mitigate ecological displacement generated by exotic fish. The introduction of native fish in polyculture systems with high commercial value fishes has provided a useful strategy for sustainable aquaculture de...
