However, individual muskellunge may migrate up to at least 40 km between spawning areas and nonspawning areas (Becker 1983), so occurrences may be large. It is important to evaluate seasonal changes in habitat to ensure that an occupied habitat occurrence for a particular population does not artificially separate spawning areas and nonspawning areas as different occurrences. <br> Separation distances (in stream kilometers) are arbitrary but reflect the probability that these relatively large fishes move large distances and so warrant a large separation distance. Because of the difficulty in defining suitable versus unsuitable habitat, especially with respect to dispersal, and to simplify the delineation of occurrences, a single separation distance is used regardless of habitat quality. A gap of 10 km or more of any apparently unoccupied aquatic habitat separates occurrences.","versionDate":"2001-05-21","versionAuthor":"Hammerson, G.","versionNotes":null,"lastModified":"2020-04-30T02:09:23.743159Z"}],"plantCharacteristics":null,"elementManagement":{"elementGlobalId":102929,"eoManagementGroupName":null,"stewardshipOverview":null,"impacts":"Where introduced, this fish can be a threat to native fish species.","restorationPotential":null,"siteConservationPlansConsidered":null,"managementMethods":null,"monitoringMethods":null,"managementProgramContacts":null,"monitoringProgramContacts":null,"managementResearchPrograms":null,"managementResearchNeeds":null,"biologicalResearchNeeds":null,"additionalTopics":null},"occurrenceViabilities":[{"eoRankSpecsDetailId":104424,"eoRankSpecsGroupName":null,"locationUseClass":{"id":1,"locationUseClassDescEn":"Not applicable","locationUseClassDescEs":"No se aplica","locationUseClassDescFr":"Sans objet","displayOrder":1},"excellentViability":null,"goodViability":null,"fairViability":null,"poorViability":null,"viabilityJustification":"Use the Generic Guidelines for the Application of Occurrence Ranks (2008).<br>The Key for Ranking Species Occurrences Using the Generic Approach provides a step-wise process for implementing this method.","versionDate":null,"versionAuthor":null,"versionNotes":null,"lastModified":"2020-05-14T02:22:46.631649Z"}],"references":[{"id":153052,"citation":"Becker, G.
