Capture fisheries is also a system. It links fish and the aquatic environment – be it the sea, a river or
a lake – with humans, as fish are captured, processed, sold and eaten. This sequence of interactions
in the system starts with the fish and the ecosystem and goes through many different steps until it
reaches the consumer. This chain is called the fish supply chain. It is important to understand the
impact of an action or change on the whole system. Each element has a value and role in the system,
and the system may not work well when one element is changed or missing. As ecosystems are
always changing as a result of varying conditions, they have a limited life span. Therefore, ecosystem
health is closely linked to the idea of sustainability. A sustainable ecosystem is one that has all the
elements living in balance that are capable of surviving, functioning and renewing themselves over
time.
