摘要：Various methods have been used to monitor fish aggregations, ranging from diver based
underwater visual surveys that are commonly used in shallow tropical waters (Sadovy et al.
2005), to industry based acoustic surveys that are used on deeper temperate water species such
as orange roughy (Hoplostethus atlanticus) and blue grenadier (Macruronus novaezelandiae)
(Honkalehto and Ryan 2005, Tilzey et al. 2006). The methods used are based on logistics and
characteristics of the species, with no single method appropriate in all situations.
