Abstract:
Data are from underwater visual surveys of fish stocks from 41 survey sites on the islands of Oahu and Hawaii, conducted by biologists and technicians of Hawaii's Division of Aquatic Resources (DAR). Survey data at Kealakekua Bay, Island of Hawaii, begin in 1952. Data begin in 1968 for all other sites. The datasets end in 2000, although updates are pending.

Serious weaknesses of the data include that (1) transect dimensions were not consistent even within survey sites, and have not generally been recorded on datasheets; (2) survey locations are generally given as place names which are at least somewhat meaningful (e.g. the Monument site at Kealakekua Bay is in front of Cook's Monument), but lat/long of start and end points are not given, and even more fundamentally depth ranges are not given; and (3) some surveys were conducted on SCUBA and some on snorkel but, again, that has not been consistently recorded on datasheets.

Additional DAR data from other locations and dates are planned for digitization.

Purpose:
Support restoration of sport fish and sustainability of ecosystem resources

Process_Description:
Serious weaknesses of the data include that (1) transect dimensions were not consistent even within survey sites, and have not generally been recorded on datasheets; (2) survey locations are generally given as place names which are at least somewhat meaningful (e.g. the Monument site at Kealakekua Bay is in front of Cook's Monument), but lat/long of start and end points are not given, and even more fundamentally depth ranges are not given; and (3) some surveys were conducted on SCUBA and some on snorkel, but, again, that has not been consistently recorded on datasheets.

All surveys done by pairs of divers (or snorkellers) either following a transect or a known stretch of shoreline. Divers swam in parallel recording the number, size (in inches) and taxa of all fishes within non-overlapping transects (i.e. each diver maintained a separate count-- the data were later pooled). Transect widths were generally 40ft (20ft on either side of each observer) for divers on snorkel and 20ft (10ft on each side of each observer) for snorkel surveys.

At Waikiki , surveys started and ended at known shoreline reference points, but mostly had lengths of around 300 to 400yds. For that location only, survey area estimates in the database are likely to be reliable.

At all other locations, survey lengths were generally (but apparently not always) 250yds. The survey transect was demarcated by laying out a weighted line from a boat starting from a standard triangulated position (location of which was known to existing staff) and in a standard direction. After a full 250 yd line has been laid out, the boat would return to the starting point and 2 divers or snorkellers would enter the water and follow the laid out line (hence considerable variability among the exact areas covered each time).

The attached database includes a record for each survey, with location and date (and when know, observers), and with information on whether surveys were done by snorkel and survey. For each record, survey area (m2) is given based on a variety of existing DAR records. It is probably reasonable to assume that survey areas of Waikiki transects are accurate, but all others are potentially wildly inaccurate. Default assumption for non-Waikiki should be that surveys were 250 yds long by 80ft wide for SCUBA surveys (each diver doing 250yds*40ft) and half that for snorkel surveys. However, as should be very apparent, it would be wise to rely too heavily on those assumptions.

Data were not centrally stored in electronic form, but copies of data sheets can still be unearthed at various storage areas in the DAR Oahu office. Starting in late 2003, DAR staff have gradually entered some of the data into an MS Access database, ie., the data included here. Considerably more data exists on data sheets for a variety of locations on Hawaii and Maui, and from Hanauma Bay on Oahu, and will be added to this database over the coming years.
