Yolk and oil globule utilization and developmental morphology of the digestive tract epithelium in larval rabbitfish, Siganus guttatus (Bloch)
(Elsevier, 1987)
The purpose of this study was to find out how yolk and oil globule absorption in Siganus guttatus proceed as the digestive tract develops, in order to determine the probable causes of early larval mortality. Yolk and oil ...

(Taylor & Francis, 1987)
Oreochromis niloticus fry reared in 50 L aquaria at a density of 1,000 fry manifested mortalities of 15% daily. Afflicted two-week old fry exhibited darker pigmentation, emaciation lesions, and surface swimming. Parasites ...
Evaluation of the high rate algae pond system for softdrink waste treatment and for fish culture.
(Asean Journals Ltd., 1987)

Induced spawning of maturing milkfish (Chanos chanos Forsskal) with gonadotropin-releasing hormone (GnRH) analogues administered in various ways
(Elsevier, 1987)
The response of mature female captive milkfish to mammalian and salmon gonadotropin-releasing hormone analogues (mGnRH-A and sGnRH-A) was investigated. Prior to spawning, six groups of three females received (1) 10–16 μg ...
