Guam Species Groups and Fisheries Categories

The species, families, and other groups used in the Guam DAWR tables and graphs are defined in this section. The species names are affected by differences in usage of local common names, and are currently being updated for consistency across regions. There have been changes in management groupings and in some cases the taxonomy has been reviewed or revised, affecting the appropriateness of former groupings. For example, the Magnuson Fishery Conservation and Management Act of 1976, was amended in 1992 to include tunas in the Pelagic Management Unit Species (PMUS) category. And species such as the dogtooth tuna have been recognized as not being true tunas (members of the Tribe Thunnini), although the word “tuna” is part of the common name.

These species tables are being revised to associate scientific names with English and local common names, and taxonomic groups will be clarified in this context. This is part of an ongoing effort to overhaul WPacFIN taxonomic references, to improve consistency and ease of interpretation for all our Pacific island partners.

The common names and corresponding scientific names are provided on this page. For the time being, the original species categorizations are used in the tables and graphs for comparative purposes.

1 Please note that in the CNMI, the kalikali is typically the “yellowtail Kalikali,” Pristipomoides auricilla, but on Guam this market category refers to the “pink Kalikali,” Pristipomoides sieboldii. This is one of the reasons scientific names are provided as a reference for common names used for each island area throughout this data.
2 This group includes species that comprise a very small portion of the catch, unidentified tunas, and apparent misidentifications. Because of the small amount of catch, and the tendency of vendors to throw in the dogtooth tuna with this group (although it is not actually a tuna), this group is combined with “other scombrids” in some of the charts.
3 May include any of the members of the larger group, which the vendor weighed as a lot to save time.
4 May include various deep bottom snappers (most Etelinae, some Lutjanus spp. listed above), groupers (Serranidae), emperors (Lethridae), deep jacks and trevallies (Carangidae).
5 Another catch all group, not necessarily distinct from “Bottomfishes.”
6 Eteline snappers are found only in bottomfishing catch; inshore near reefs, they are mainly species of Lutjanus.
