The Oxygen Requirements of Fishes (OXYREF) data base is
an ASCII text, non-binary, file that contains test results
reported in published literature on the respiratory oxygen
requirements of fishes.

This file is based on results of
a computerized literature search, over the time period 1969-1986,
of three separate journal referencing services: Biological
Sciences Information Service (BIOSIS PREVIEWS), Aquatic
Sciences and Fisheries Abstracts (ASFA), and Canadian
Water Resources References (AQUAREF). Key words used
in the search included that for fishes as a group, and
any combination with oxygen, respiration, ventilation, and gases.
The minimum information needed for a test to qualify
for OXYREF was identification of the test fish species,
number of fish per test, fish weight, test temperature,
indication of fish activity (which we classified according
to the conventional metabolic activity categories: standard, routine,
active, and burst), and oxygen consumption per unit of time.
If there was more than one fish in a test, the weight recorded
in the file is the mean weight. If test salinity was not reported,
it was recorded as 35 o/oo for a marine species and as 0 o/oo for
a freshwater species. Partial pressure of oxygen in the test
water (in mm Hg) was recorded as reported, or if not reported
it was possible to make certain assumptions for most tests from
the description of the test methods. When assumptions about partial
pressure were made, these included corrections for test temperature
and water salinity.
Oxygen consumption was reported in a variety of ways, but all
were converted to mg O2 per kg of fish per hour (mg/kg/h). Additional
information recorded for each test, if available, included
fish length, age (in years), sex (female, male, both, or unknown),
and swimming speed, either reported as, or converted to, body lengths
per second (bl/s).
OXYREF also includes the literature reference for each test, and, where
appropriate, explanatory comments that sometimes describe the purpose of the test.
Although OXYREF contains information only from publications reporting primary data,
the operating definition of primary data included coordinate measurements of data points read
from graphs if that was the only way the data were presented. If data were presented in both
tabulated and pictorial form, tabulation was chosen.
