6. Blood potassium concentration (ls mean mEq/L ± s
(N))
in adult yellowtail flounder trawl-collected from six Northwest Atlantic
locations during 1978-85. (Station-related differences (i.e., between
the five inshore stations and the Georges Bank offshore station) for
a given season and sex are indicated by bold values (read horizontally).
Season-related differences for a given station and sex are indicated
by the presence or absence of superscripts for the values (read vertically);
values with the same or no superscript are not significantly different;
values with different superscripts are significantly different. Sex-related
differences for a given station and season are indicated by underlined
values (read vertically). For some stations and
seasons, no data (“nd”) were available. For statistical significance, P < 0.05.)'
