Potential biological removal and other currently used management rules for marine mammal populations: A comparison

摘要: Abstract The management of marine mammal populations requires the balancing conflicting interests and also compliance with national legislation international agreements. These conflicts are intensifying it is becoming urgent that goals, justifications, clear explicit. This paper summarises six methods currently used to assess status populations: IUCN Red List Criteria; regulations under European Union Habitats Directive; PBR; IWC's Revised Management Procedure; HELCOM's approach managing seals; Canadian Objective-Based Fisheries system for harp seals. It compares assumptions implications then describes how one them, PBR, can be re-presented make explicit subjective choice at its centre, push decision about conservation targets back from scientists policymakers, where belongs.
