The transformation of the shrimp industry from one based on
wild harvest from the oceans to intensified culture in coastal
ponds has involved changes at multiple levels affecting many
different actors (Fig. 1). In this paper we focused on what drove
a switch from one species to another and the consequences
this had for the environment and farmers (Fig. 4). The systems
innovation approach helped clarify several issues hinted at in
earlier studies about the shrimp aquaculture industry.
