Description
Marine invertebrate species of commercial interest observed in Tonga during the PROCFish/C surveys (2002 to 2006) in Tongatapu with a mix of survey methods (manta tow, reef benthos transects, and day and night searches)
Data Records
The data in this occurrence resource has been published as a Darwin Core Archive (DwC-A), which is a standardized format for sharing biodiversity data as a set of one or more data tables. The core data table contains 1,715 records.
This IPT archives the data and thus serves as the data repository. The data and resource metadata are available for download in the downloads section. The versions table lists other versions of the resource that have been made publicly available and allows tracking changes made to the resource over time.

Project Data
The Pacific Regional Coastal Fisheries Development Programme (CoFish) and its associated programme PROCFish/C (the coastal component of the Pacific Regional Oceanic and Coastal Fisheries Development Programme) conducted fieldwork in 63 sites across 17 Pacific Island countries and territories over a seven-year period from 2002 to 2009.
| Title | Pacific Regional Oceanic and Coastal Fisheries Development Programme (PROCFish/C) |
|---|---|
| Identifier | BID-PA2016-0002-REG |
| Funding | Funded by the European Union for the implementation of the Pacific Regional Coastal Fisheries Development Programme (CoFish), which ran from 1 May 2004 to 31 December 2009 under funding from the ninth European Development Fund (EDF 9), and the coastal component of the Pacific Regional Oceanic and Coastal Fisheries Development Programme (PROCFish/C), which ran from 1 March 2002 to 28 February 2009 under funding from the eighth European Development Fund (EDF 8). Data prepared and published under project "Capacity building and data mobilization for conservation and decision making in the South Pacific" - BID-PA2016-0002-REG |
| Design Description | The aim of the survey work was to provide baseline information on the status of reef fisheries, and to help fill the massive information gap that hinders the effective management of reef fisheries. |

Sampling Methods
Diversity and abundance of invertebrate species were determined using a range of survey techniques, including broad-scale assessment (using the manta-tow technique) and finer-scale assessment of specific reef and benthic habitats. Broad-scale assessments were used to record large sedentary invertebrates; transects were 300 m long × 2 m wide, across inshore, midshore and more exposed oceanic habitats. Fine-scale assessments were conducted in target areas (areas with naturally higher abundance and/or the most suitable habitat) to specifically describe resource status. Fine-scale assessments were conducted of both reef (hard-bottom) and sandy (soft-bottom) areas to assess the range, size, and condition of invertebrate species present and to determine the nature and condition of the habitat with greater accuracy. These assessments were conducted using 40 m transects (1 m wide swathe, six replicates per station) recording most epi-benthic resources (those living on the bottom) and potential indicator species. For trochus and bêche-de-mer fisheries, searches to assess aggregations were made in the surf zone along exposed reef edges. On occasion, when time and conditions allowed, dives to 25–35 m were made to determine the availability of deeper-water sea cucumber populations. Night searches were conducted on inshore reefs to assess nocturnal sea cucumber species See http://purl.org/spc/digilib/doc/pfj5w

Method step description:
- Multiple observations for the same species aggregated by replicate. For replicates with a start and end positions (manta tow), the position provided is the middle point.
