Mangroves as nurseries: Shrimp populations in mangrove and non-mangrove habitats
(Elsevier, 1998)
A total of 4845 penaeids belonging to nine species—Metapenaeus anchistus, M. ensis, M. moyebi, M. philippinensis, Penaeus merguiensis, P. monodon, P. semisulcatus, P. latisulcatus and Metapenaeopsis palmensis—were collected ...
Assessment of stocks of a natural Gracilaria population on Panay Island, Philippines
(Walter de Gruyter, 1991)
Two peaks in biomass were recorded from natural beds of Gracilaria sp. at Leganes, Iloilo and Batan, Aklan study sites. The major peak occurred in February 1989 for both areas. The minor peak occurred in September 1988 at ...
Agar production from Gracilariopsis heteroclada (Gracilariales, Rhodophyta) grown at different salinity levels
(Walter de Gruyter, 1994)
Gracilariopsis heteroclada grown in fiber glass tanks at four salinity levels was treated with three different concentrations of aqueous NaOH. Yield, gel strength, gelling and melting temperatures of the extracted agar ...
Survival of Penaeus monodon postlarvae and juveniles at different salinity and temperature levels.
(Society of Israeli Aquaculture and Marine Biotechnology, 1998)
Penaeus monodon postlarvae (PL1, PL5, PL10, and PL15) and juveniles (0.2 and 2 g mean weights) were acclimated gradually within 6 h to test temperatures of 22°, 28°, and 33°C. After 24 h, the postlarvae were abruptly ...
Assimilation of aquatic macrophytes in Penaeus monodon
(Taylor & Francis, 1993)
The macrophytes Najas graminea and Ruppia maritima are common aquatic plants found in brackishwater ponds in the Philippines. The assimilation efficiencies of these plants by male and female Penaeus monodon (30-40 g wet ...
