Evaluating and Understanding Fish Health Risks and Their Consequences in Propagated and Free-Ranging Fish Populations

摘要: Fishery managers and resource conservationists are increasingly interested in understand- ing the fish health disease risks of free-ranging fishes whether propagated or features practices used at culture facilities pose a risk to populations. Disease agents present most both captive all populations, but consequences extent infections populations often difficult measure, control, understand. Sampling methods, protocols, assay techniques developed assess not as applicable for assessments fishes. The use chemicals therapeutics control diseases parasites likely reduces introducing specific pathogens into environment, measures may have localized effects on environment surrounding facilities. To understand propa- gated free ranging fishes, we must consider facilities, releases, their interactions within greater geospatial aquatic environment.
