Pelagic fish food web linkages, Queensland, Australia (2003-2005)

OBIS and OBIS Australia

This data was collected to primarily provide preliminary information on the diets of ten pelagic fish species common to the Northern Prawn Fishery, specifically to investigate any effects of prawn predation by pelagic fish. After the project was initiated the scope of the study was broadened to investigate the age, growth (by otoliths) and reproductive dynamics (by GSI and histology) of these species. Tissue samples from at about 100 specimens representing each species were also taken and stored in DMSO solution and is available for any researcher wishing to undertake a genetic stock structure study. This study was solely funded by CMR as a pilot study. As a result of limited funds, fish specimens were collected opportunistically from recreational fisher donations, commercial catches and from bycatch samples from scientific cruises. As a result, the capture location of the majority of specimens does not have a lat/long, and is generally only identified by the general area of capture (i.e. 'Weipa' or 'Gladstone'). The method of capture was recorded to the best of our knowledge (i.e. hook and line, gillnet etc), although actual gear specifications and shot information were generally not available.

N/A

This dataset was downloaded from OBIS (https://obis.org/). The records for only marine mammals, seabirds, sea turtles and rays and sharks were extracted. Records with no longitude/latitude or no date (eventDate) were excluded.

Overview

This section explains attributes included in the original dataset. OBIS-SEAMAP restricts the attributes available to the public to date/time, lat/lon and species names/counts only. Should you need other attributes described here, you are encouraged to contact the data provider.

Attributes described below represent those in the original dataset provided by the provider.
All attributes are included in the downloadable file (CSV or ESRI File Geodatabase) for "Complete Set of Dataset".
