Cryopreservation of different strains of the euryhaline rotifer Brachionus plicatilis embryos
(Japanese Society of Fisheries Science, 1991)
Cryopreserevation of different strains of Brachionus plicatilis symmetrical stage embryos was conducted. One S-type strain, namely Yashima-S (YS), and three L-type strains, namely Yashima-L (YL), Nagasaki (NG), and Hamana ...

Increasing milkfish (Chanos chanos) yields in brackishwater ponds through increased stocking rates and supplementary feeding
(Asian Fisheries Society, 1990)
Brackishwater milkfish culture in the Philippines is normally practiced at fish stocking rates of 2,000-3,000 ha<sup>-1</sup> with fertilizers as the sole nutrient input. Supplementary feeding is not common. We stocked two ...
Daily amount of rotifers taken by a sea bass Lates calcarifer larvae
(Science and Technology Information Institute, 1990)
The amount of rotifers consumed by a single sea bass Lates calcarifer larva per day (R) was examined by both the direct and by the satiation-digestion methods. In the direct method, R is estimated by the number of rotifers ...
The milkfish fry shortage in the Philippines and supply from fisheries and hatcheries

Dessication, thermal shock, ultraviolet-irradiated seawater, and hydrogen peroxide, singly or in combination, failed to induce the tropical abalone, Haliotis asinina to spawn viable number of eggs or sperm. However, natural ...
Stable carbon and nitrogen isotope ratios of penaeid juveniles and primary producers in a riverine mangrove in Guimaras, Philippines
(University of Miami, Rosenstiel School of Marine and Atmospheric Science, 1996)
Stable carbon and nitrogen isotope ratios were analyzed for primary producers and juveniles of four penaeid species (Metapenaeus ensis, Penaeus indicus, P. merquiensi and P. monodon) in a riverine mangrove in Guimaras, ...
Economic analysis of prawn (Penaeus monodon) culture in the Philippines, I. Hatchery operations
(Asian Fisheries Society, 1995)
High prices of prawn (Penaeus monodon) fry, profitability of hatchery operations, and a low cost hatchery design introduced by the Southeast Asian Fisheries Development Center attracted millions of dollars of investments ...
Successive spawning of grouper, Epinephelus suillus (Valenciennes), in a tank and a floating net cage
(Elsevier, 1993)
Wild Epinephelus suillus (Valenciennes) were collected in 1989 to early 1990. To monitor natural spawning in captivity, 6 mature females (3.5–5.0 kg) and 4 mature males (7–12 kg) were transferred to a 4.6×4.6×2 m concrete ...
Economic assessment of commercial hatchery production of milkfish (Chanos chanos Forsskal) fry
(John Wiley and Sons, 1999)
The economic viabilities of two types of commercial hatchery milkfish (Chanos chanos) fry operations were assessed and compared. Based on the actual cost of input, the physical facilities, and the potential production ...
