Flounder metamorphosis: its regulation by various hormones
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1996)The elongation and shortening of the flounder fin rays during its metamorphosis may be parallel to the appearance and resorption of the tadpole tail during amphibian metamorphosis. The dorsal fin rays of the Japanese ... -
Role of growth hormone in the adaptation to sea water of juveline brown trout, (Salmo trutta)
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1996)The first part of the study investigates the ability of ovine growth hormone (oGH) to enhance the hypo-osmoregulatory and growth performance of juvenile brown trout after exposure to sea water (SW). Three groups of fish ... -
