Effect of different diets on the ultrastructure of hepatocytes of Chanos chanos fry (Chanidae: Teleostei): An electron microscopic and morphometric analysis
(Springer-Verlag, 1983)
The hepatocytes of milkfish fry offered different artificial diets (carbohydrate-, lipid-, protein-oriented) and live food (Artemia spp., Brachionus plicatilis) differ considerably both qualitatively and quantitatively as ...
Occurrence and pathology of an Amyloodinium-like protozoan parasite on gills of grey mullet, Mugil cephalus
(Biologische Anstalt Helgoland, 1984)
In cultured grey mullets, Mugil cephalus L., mortalities caused by a dinoflagellate-like parasite were observed under normal rearing conditions. Moribund fish were abnormally swimming near the water surface and exhibited ...
Uptake and elimination of iodine-131 by the freshwater clam Corbicula manilensis Philippi from water
(College of Arts and Sciences, University of the Philippines, 1988)
Whole body uptake of Iodine-131 by the freshwater clam, Corbicula manilensis, from contaminated water was followed using NaI scintillation counter. The bioaccumulation factor (BF) exclusive of shell was 5.44. The degree ...
Fry-to-fingerling production of Tilapia nilotica in aquaria using phytoplankton as natural feed
(University of the Philippines at Los Baños, 1982)
Two experiments were conducted to demonstrate the efficiency of phytoplankton as natural feed in fry-to-fingerling production of Tilapia nilotica . In the first experiment, growth and survival rates of fry given a sustained ...
Acclimation of Penaeus monodon postlarvae to fresh water
(Fisheries Research Society of the Philippines, 1980)
Gradual acclimation of Penaeus monodon Fabricius to fresh water was conducted in glass aquaria and marine plywood tanks over a one-day, two-day, and three-day acclimation periods. Different stages of postlarvae were ...
Effects of initial stocking size on the growth of Nile tilapia fingerlings in cages without supplemental feed in Laguna Lake, Philippines
(University of the Philippines, 1988)
Oreochromis niloticus fingerlings were stocked at three different initial size ranges of 1-3, 7-12 and 20-30 g in fixed net cages in Laguna Lake, Philippines. These were reared without supplemental feed for 120 days. ...

The authors surveyed the fishing methods and gears in Panay and smaller neighboring islands in the Philippines in September-December 1979 and in March-May 1980. This paper is a report on the fishing methods and gears used ...
Shift in steroidogenesis in the ovarian follicles of the goldfish (Carassius auratus) during gonadotropin-induced oocyte maturation
(Japanese Society of Developmental Biologists, 1986)
Both partially purified chum salmon gonadotropin and 17α-hydroxyprogesterone stimulated in vitro production of testosterone by postvitellogenic follicles of goldfish (Carassius auratus). Chum salmon gonadotropin further ...
Specific amino acid-free semi-purified diets for Penaeus monodon juveniles
(Kagoshima University Research Center for the South Pacific, 1986)
To determine the effects of deficiency of individual amino acids believed to be essential to Penaeus monodon juveniles, a 28-day feeding experiment was carried out with P. monodon postlarvae.
P. monodon postlarvae ...
Preliminary results of feeding aquatic macrophytes to Penaeus monodon juveniles
(Elsevier, 1989)
Penaeus monodon juveniles (PL<sub>50</sub>) were fed live and decaying aquatic macrophytes and a commercial grow-out pellet (40% crude protein) in 80-l glass tanks over a 30-day period. Growth and survival were significantly ...
