Lipids are mainly storred in fish body as triacylglycerol in
several organs and tissues like liver, muscle and visceral fat. The
4-h transport did not affect the tissue lipid content in any
treatment. During the recovery, lipid reserves were mobilized
evidenced by diminished muscle lipid and blood tryacilglycerol.
Once cortisol had already returned to the resting levels at the
recovery period, it is supposed that other hormones, such as
glucagon, are involved in lipolysis. This supposition is supported
by the fact that glucagon is released during starvation period
(Suarez & Mommsen, 1987) and that matrinxãs were not fed
during the experimental period.
