Aquaculture: Fisheries and aquaculture emergency response guidance

摘要

The various segments of the aquaculture production and supply chain are invariably vulnerable to most risk events, which make the tasks of protection and rehabilitation complex and demanding. Broodstock farms (brood banks) or wild sources of broodstock, hatchery facilities, nurseries and grow out facilities are highly exposed to natural and biological hazards (with the exception of recirculation aquaculture systems or RAS3, sensitive to disruptions in power (especially RAS), and changes in water parameters. The supply of viable seed for the rehabilitation of a vast area of fish farms would depend on distant hatcheries that are not affected by the disaster. This poses difficulties in logistics as well as entails higher cost. For fed aquaculture, commercial feed sources could very well be rendered temporarily out of business or the transport and distribution systems for feed are paralyzed, or the ingredients for farm-made feed become scarce as they could also have been affected by the risk event.
