(Society of Israeli Aquaculture and Marine Biotechnology, 1999)
Mangrove red snapper, Lutjanus argentimaculatus, fry (n=30) were collected in 1993 and reared in concrete tanks. They were fed trash fish every other day initially at 10% to 5%, until they reached three years. They reached ...
Changes in the length and weight of milkfish, Chanos chanos, larvae preserved in formalin
(Fisheries Research Society of the Philippines, 1980)
Shore-caught milkfish fry (late postlarvae) and artificially-bred, laboratory-reared larvae (0-to 20-day old) were preserved in 5% and 10% freshwater-and/or seawater-formalin solutions after measuring their initial weights ...
A farmer-oriented Nile tilapia, Oreochromis niloticus L., breed improvement in the Philippines
(Blackwell Publishing, 2005)

Size measurement and nutritional condition evaluation methods in sandfish (Holothuria scabra Jaeger)
(Wiley, 2012)
The aims of this study were to establish an accurate size measurement method and a nutritional condition evaluation method of Holothuria scabra (Jaeger). Although 0.5% KCl and 0.05% MgSO<sub>4</sub> did not induce anaesthesia, ...
Baseline assessment of fisheries for three species of mud crabs (Scylla spp.) in the mangroves of Ibajay, Aklan, Philippines
(University of Miami, Rosenstiel School of Marine and Atmospheric Science, 2007)
Stock enhancement through habitat restoration and habitat release have both been considered as approaches to the management of declining Scylla spp. Prior to stock enhancement trials, the present study was conducted to ...
Effect of some vertebrate and invertebrate hormones on the population growth, mictic female production, and body size of the marine rotifer Brachionus plicatilis Müller
(Springer Verlag, 1997)
Eight vertebrate and invertebrate hormones were screened for their effect on population growth, mictic female production, and body size of the marine rotifer Brachionus plicatilis. Growth hormone (GH) or human chorionic ...
