Risk assessment for metazoan parasites of yellowtail kingfish Seriola lalandi (Perciformes: Carangidae) in South Australian sea-cage aquaculture

摘要: Metazoan parasites can threaten the sustainability and profitability of finfish sea-cage aquaculture. It is critical, therefore, to identify local parasite species determine which are potentially harmful. Although several studies have documented on wild farmed fish from aquaculture sites, few used qualitative risk analyses likelihood consequence transfer locally found fish. Indeed, most assessments for marine farming hazards diseases reported in other, often distant, countries. The usefulness this approach limited if an endemic with potential cause serious disease undetected before establishment This study performs a assessment 57 metazoan infect yellowtail kingfish (Seriola lalandi) Samson (S. hippos) southern Australia real risks S. lalandi South industry expansion elswhere.
