Abstract
Clownfish collection 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.
For species codes, see: https://www.bco-dmo.org/dataset/785633
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.
BCO-DMO Data Processing:
- refomatted 'fish_corr_date column to ISO_Date format (yyyy-mm-dd)

Relationship Description: Taxon and dive-type codes used in 2018 sampling
Relationship Description: Clownfish log dataset taken in association with the "Clownfish photos" dataset.
| Parameter | Description | Units |
| fish_table_id | unique identifier of fish observation | unitless |
| anem_table_id | unique identifier of observation event (whole number): links to the anemones table | unitless |
| fish_spp | species code of fish; can be APCL = Amphiprion clarkii; APOC = A. ocellaris; APPE = A. periderion; APSA = A. sandaracinos; APFR = A. frenatus or A. melanopus; APPO = A. polymnus; APTH = A. theillei; PRBI = Premnas biaculeatus | unitless |
| size | size of the fish - either estimated by eye or measured with calipers | centimeters |
| fin_id | tissue sample id: series begins with 1 at the beginning of the field season; reflects the number of tissue samples collected and the order except for 2015_05 field season where the last 6 digits of the pit tag were used for fish that were tagged and clipped. | unitless |
| sample_id | tissue sample id including species of fish and year collected | unitless |
| color | tail color code: can be O = a tail containing any orange color; YP = a tail that is yellow and pointed; YR = a tail that is yellow and rounded; W = a tail that contains white; B = tail that contains black; BW = a tail that is black and white | unitless |
| recap | indicates if the fish had a PIT tag when scanned: can by Y if tag was present or N if tag was not present; fish have only been scanned since 2015; previous years are null. The fish captured during Patrick's pilot study are only listed once and the recapture/size info is in their notes because there are not dive/anem_table_ids for these recapture events. | unitless |
| tag_id | tag number (including city) of PIT tag injected into fish | unitless |
| fish_notes | any notes pertaining to this fish | unitless |
| fish_collector | intials of person who filled out data sheet for this observation | unitless |
| fish_correction | Y indicates that a correction has been made to the data since data entry from the data sheet | unitless |
| fish_corr_date | the date of the most recent correction | unitless |
| fish_corr_editor | the editor of the most recent correction | unitless |
| fish_corr_message | comments on which field was changed from what old value to what new value and reason and based on what evidence. If another correction was already present then amend the message to include the date and correction editor of previous corrections | unitless |
| fish_obs_time | the time that the fish photo was taken or the fish was scanned with the pit scanner; recorded in the Asia/Manila time zone | unitless |
| sex | the sex of the fish with possible values of M = male F = female and J = juvenile | unitless |
| Dataset-specific Instrument Name | Biomark 601 PIT tag reader |
| Generic Instrument Name | tracking tag |
| Dataset-specific 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. |
| Generic Instrument 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. |

RAPID: Mega-typhoon impacts on the metapopulation resilience of coral reef fishes (Reef Fish Resilience)
Description from NSF award abstract:
When Typhoon Haiyan hit the Philippines it had sustained winds of 305 to 315 kph and was the strongest storm ever to make landfall. Storms are one of the most important disturbances to coral reef ecosystems. Previous research has primarily emphasized that habitat recovery is important for the recovery of reef fish communities after disturbance. We understand little, however, about the role of larval dispersal in mediating species responses to disturbance. Reef fish function as metapopulations connected by larval dispersal among reefs, and larval connectivity is therefore a critical process for their dynamics. A field site directly in Typhoon Haiyan's path provides an ideal opportunity to address the role of larval dispersal during recovery. Over the course of four field seasons (2008 to 2013), nearly two thousand clownfish were surveyed along 20km of coastline. Clownfish possess the same basic life history as most reef fish (sedentary adults and pelagic larvae), but are sufficiently rare and visible that genetic parentage methods can be used to follow larval dispersal. This study site is therefore a unique location in which to understand the metapopulation impacts of a massive storm. This project will focus on three hypotheses: 1) Habitat destruction determines the short-term impacts of storms disturbance, 2) Metapopulation processes shape recolonization after disturbance, and 3) Disturbance allows rare competitors to increase in abundance. The project will address these questions with a combination of fixed and random transects to assess reef habitat and reef fish abundance and diversity, as well as detailed, spatially explicit surveys of anemones and clownfish. Genetic mark-recapture and parentage methods with yellowtail clownfish will pinpoint the origin of new recruits that recolonize the reef post-typhoon.
