Description Stocking density is an important factor in
cage aquaculture of finfish. Effects of high stocking
density (35 fish cubic m-1) on a range of biochemical
and immunological parameters in Asian seabass
reared in open sea floating net cages were compared
to fish held in relatively low density (15 fish -
cubic m-1). The results revealed that chronic stress
due to high stocking density induced variations in
most of the parameters studied as evidenced by
increased cortisol and glucose levels and decreased
activity of lysozyme, myeloperoxidase and complement.
Production of reactive oxygen species, total
leucocyte count and total serum protein were also
decreased, whereas anti-protease, alkaline phosphatase
and acid phosphatase activities were increased in
high stocking-density group when compared to low
stocking-density group. Effects of chronic stress due
to high stocking density were discussed in relation to
variations in these parameters.
