Pomacentrids survey data from long-term vermetid removal reefs in Moorea, French Polynesia from 2013-2015

Expand/Collapse All

Description

Pomancentrid identity, size and abundance were enumerated around the Long Term Vermetid Removal (LTVR) Reefs 129-144 and 193-198 beginning in 2012. Common Pomancetrids were recognized and size class determined. Together all of these data provide information about the factors that may influence (or be influenced by) Thalassoma and Vermetid.

Long Term Vermetid Removal (LTVR) Reef sites in this project are manipulated reefs characterized in the Long Term Reef Physical Characteristics dataset.

Reefs numbered 129-144, are a subset of a larger number of Long Term Reefs (LTR) that were monitored as part of the project "Cryptic density dependence: the effects of spatial, ontogenetic, and individual variation in reef fish" beginning in 2003. This long term study continues to monitor those reefs in addition to reefs 193-198 starting in 2012. Data for these reefs between the years 2003 and 2009 can be found on the project site http://www.bco-dmo.org/project/540423.

Location: Moorea, French Polynesia (17.48 degrees S, 149.82 degrees W)

Methods & Sampling

Sampling and Analytical Methodology:
A single snorkeler approaches one of the patch reefs (for size of reef, see the “physical characteristics” file in the project “Cryptic density dependence: the effects of spatial, ontogenetic, and individual variation in reef fish”). He or she swam around the reef, recognized and estimated the size of all the common Pomacentrids in broad size categories depending on the species. The rare species were just counted.

Materials: Snorkel, dive slate

Instruments

Diving Mask and Snorkel

Supplied Name: Mask and snorkel

Supplied Description:

Instrument Type

Generic Name: Diving Mask and Snorkel

Generic Description:

A diving mask (also half mask, dive mask or scuba mask) is an item of diving equipment that allows underwater divers, including, scuba divers, free-divers, and snorkelers to see clearly underwater.

Snorkel: A breathing apparatus for swimmers and surface divers that allows swimming or continuous use of a face mask without lifting the head to breathe, consisting of a tube that curves out of the mouth and extends above the surface of the water.

Measuring Tape

Supplied Name: Transect Tape

Supplied Description:

Materials: transect tape and slates

Instrument Type

Generic Name: Measuring Tape

Generic Description:

A tape measure or measuring tape is a flexible ruler. It consists of a ribbon of cloth, plastic, fibre glass, or metal strip with linear-measurement markings. It is a common tool for measuring distance or length.

Underwater Writing Slate

Supplied Name: Slate

Supplied Description:

Materials: transect tape and slates

Instrument Type

Generic Name: Underwater Writing Slate

Generic Description:

Underwater writing slates and pencils are used to transport pre-dive plans underwater, to record facts whilst underwater and to aid communication with other divers.
