This thesis can be found at The National Library The Library of Nha Trang University INTRODUCTION The production of rabbitfish in Vietnam in particular and the world in general still faces various restrictions such as low spawning rate difficult larval rearing leading to the low survival rate of larvae and difficulty in achieving fingerling size. Currently research on reproductive biology physiology reproductive endocrinology and reproductive stimulation in captivity has not received sufficient attention 17 . In addition the study of changes in steroid hormone levels during the spawning cycle in rabbitfish has not been conducted 2 . In that setting the topic quot Study on the plasma steroid hormone levels in the reproductive cycle of the rabbitfish Siganus guttatus Bloch 1787 quot was carried out which aims at providing scientific data contributing to perfect the process of artificial reproduction and rabbitfish hatchery. The objective of the study Clarifying the fluctuation of steroid hormone levels in the blood plasma of rabbitfish Siganus guttatus Bloch 1787 during the spawning cycle as a basis for studies on artificial reproduction of rabbitfish in particular and marine fish in general. Scientific of the study Research can be attributed to agencies universities and research institutes by providing methodology information knowledge of fish reproductive endocrinology for university .
