* » Abstract |
The data described here include prey item identifications and specifications from dissected stomachs of longnose lancetfish, as part of NOAA's ongoing Lancetfish diet study. These data were gathered around the North Pacific from 2014 to 2023 and are currently ongoing. These data are part of NOAA Pacific Islands Fisheries Science Center (PIFSC), Ecosystem Sciences Division (ESD), Pelagic Research Program (PRP). These stomachs were collected from Pacific Islands Regional Office (PIRO) observers aboard longline vessels and prey data were recorded by employees in the labs at PIFSC. |
* Purpose |
The Lancetfish diet study is crucial to understanding the midwater prey community that supports other pelagic predators of interest like tuna and billfish. Lancetfish are common bycatch on the tuna longlines and are easily accessible. They provide us with high-quality prey that facilitate easy identification. |

Accuracy |
There are two species of lancetfish that are known to exist, however the shortnose lancetfish has not been found in the areas around the Hawaiian Islands. Prey items are identified with the help of experts at PIFSC and Scripss Institution of Oceanography using expertise and taxonomic identification guides. |

Completeness Report |
This is an ongoing time series data beginning in 2014. We have over 4,000 stomachs recorded with prey identifications made to the lowest taxonomic rank when possible. Sampling was paused during the COVID pandemic and resumed in 2022. Samples that do not contain corresponding catch data are not utilized. |
Conceptual Consistency |
All stomachs are processed in the same manner. |
» Quality Control Procedures Employed |
The diet database is thoroughly analyzed each year and revised when necessary. |
