Unique identifier for fish REA observations

Unique Identifier for ROUND record

Mission Identifier

One of the five Pacific Island regions CRED surveys

Island or Atoll surveyed

This field is used by the fish team to represent a different stratification scheme based on fishing pressure and wave exposure around an island

District / municipality specifically for sites in Timor Leste

The 5- to 6-character code for the site surveyed. Combines a 3-letter island code with a site number

Site latitude as recorded by divers on the Dive & Nav Info datasheets in decimal degrees

Site longitude as recorded by divers on the Dive & Nav Info datasheets in decimal degrees

The reef zone for the given site (Forereef, Backreef or Lagoon)

Classification of depth (shallow, mid, deep) based on midpoint between minimum and maximum depths of replicates at this site. Shallow=0-6 m, Mid=6-18 m, Deep=18-30 m

Unique Identifier for SITE_VISIT record

Date the survey was conducted

Year the survey was conducted

Initials of diver conducting survey

Unique identifier for the replicate sample within a Fish REA survey

Letter associated to replicate (A, B, C, or D)

Fish method employed: belt transect (BLT), stationary point count (SPC), or new stationary point count (nSPC)

Flag to indicate photographer of benthic photos. Two divers simultaneously conduct a survey at a site (indicated by the initials of the observer in the DIVER field), only one of which captures the benthic photos. Value = -1 indicates the photographer.

4-letter species code

Scientific name

Common name (from FishBase)

Common name of all families

Taxonomic family classification

Lowest defined rank in taxonomic hierarchy

AphiaID

Trophic level: APEX (apex predator), Cor (corallivore), H (herbivore), MI (mobile invertivore), Om (Omnivore), Pisc (piscivore), Pk (planktivore), SI (sessile invertivore), Z (zooplantivore)

Trophic level scheme used (Primary Consumer, Secondary Consumer, Planktivore, Piscivore)

Parameter "a" used in length-weight calculations

Parameter "b" used in length-weight calculations

Maximum length of the fish published in literature

Factor to convert length as total length by to get it to right form (SL or FL or TL) for available length weight A and B parameters for this species

Number of fish observed during survey

Total length of fish, measured from the tip of the snout to the tip of the longer lobe of the caudal fin, reported in centimeters. Total length for rays (Myliobatidae) is measured from pectoral fin tip to pectoral fin tip.
