Description

Dive log from the west coast of Leyte, the Philippines in the municipalities of Albuera (10.91667, 124.69667) and Bay Bay City (11.07611, 124.87528), 2012-2018.

Methods & Sampling

Dataset acquisition description

Anemone surveyor:
- searches adjacent area for anemone tag (anemone could have moved a few feet since last encounter)
- records time, species, size of anemone, tag number if present
- watches anemone and counts number of fish and estimate sizes (same procedure regardless of species)
- records species of fish, estimate sizes
- adds tag after the fact if one was missing or if there was only one zip tie tag (old system tag)
- flags anemone with flagging tape that it is ready to be hunted if APCL were present.

Fish catcher:
- waits for flagging tape to indicate anemone is ready for fish capture, ok to chase fish if they fled the area
- catches all fish of desired size range and places in holding vessel adjacent to anemone
- can move on to next anemone if anemone surveyor has flagged it

Data entry was made with Excel or Google sheets, depending on the internet connection.
Data cleaning was performed in R using the tidyverse package.

Instruments

tracking tag

Supplied Name: Biomark 601 PIT tag reader

Supplied Description:

Passive Integrated Transponder (PIT) tags help scientists track individual organisms by providing a reliable lifetime 'barcode' for an individual animal. PIT tags are dormant until activated; they therefore do not require any internal source of power throughout their lifespan.To activate the tag, a low-frequency radio signal is emitted by a scanning device that generates a close-range electromagnetic field. The tag then sends a unique alpha-numeric code back to the reader (Keck 1994). Scanners are available as handheld, portable, battery-powered models and as stationary, automated models that are usually used for automated scanning.

Instrument Type

Generic Name: tracking tag

Generic Description:

Devices attached to living organisms with the purpose of determining the location of those organisms as a function of time after tagging and release.
