Description

Data on lionfish tagged for an assessment of juvenile growth patterns in the native Pacific (Guam and the Philippines) vs. invasive Atlantic (Bahamas and Caymans). Data from the Cayman Islands are in separate dataset: see the comparative lionfish growth - Caymans dataset.

Methods & Sampling

Dataset acquisition description

This sub-project aimed to compare native vs. invasive populations of lionfish, in order to assess some of the potential factors responsible for the invasive success of lionfish in the Atlantic. Assessment in the native range included analysis of behaviour and juvenile growth patterns, at two general locations: Guam and the Philippines. To assess growth, juvenile fish found mostly at shallow water sites, were inividually identified with the use of fluorecent elastomer tags (different colors and body positions) and measured to the nearest mm. Individually tagged fish were later relocated and remeasured at 2 week intervals, in order to obtain estimates of in-situ growth. Observations in the native range were then compared to those at invaded locations (Bahamas and Caymans). Data were QA/QCd by spot checking against original field data sheets.

Data Processing Description

Dataset Processing Description

BCO-DMO Processing Notes:
- Changed parameter names to conform with BCO-DMO naming conventions.
- Added lat and lon for each site from the metadata sheet.
- Replaced blanks with 'nd' to indicate 'no data'.
- Replaced commas with semi-colons in the columns containing text.
- Moved comments about site, fish, etc. to a single column ('notes').
- Re-arranged data so that date, day_num, and len_tot are in separate columns.
- 27-Dec-2017: removed embargo on dataset.
