significantly lower than at high DO level (P=0.029). There was a
tendency that final moisture content in fish at low DO level was higher
than at high DO level (P=0.073) and final protein content in fish at low
DO level was lower than at high DO level (P=0.054). There were no
interaction effects of size and oxygen on moisture, crude protein and
crude fat contents (PN0.05), although a tendency on crude fat content
was found (P=0.058).
