Occurrence and pathology of Penaeus monodon baculovirus infection in hatcheries and ponds in the Philippines
(Society of Israeli Aquaculture and Marine Biotechnology, 1991)
Samples from Penaeus monodon hatcheries (2-3 day old larvae or Zoea 1 to 34 day old post larvae or PL<sub>34</sub>) and ponds (15 to 159 days old in the pond) were histologically examined for the presence of eosinophilic ...
Growth of Gracilaria sp. (Gracilariales, Rhodophyta) in brackishwater ponds at different stocking densities.
(Society of Israeli Aquaculture and Marine Biotechnology, 1993)
The specific growth rate (% per day) and net production rate (g per m<sup>2</sup> per day) of Gracilaria sp. cultivated in net cages in a brackishwater pond were determined at different stocking densities (200, 250, 300 ...
Influence of stocking density and fertilization regime on growth, survival and gross production of Penaeus monodon Fabricius in brackishwater ponds
(Society of Israeli Aquaculture and Marine Biotechnology, 1991)
Twelve 0.1 ha earthen ponds were stocked at 3,500 or 7,000/ha with 1-month old nursery reared Penaeus monodon Fabricius (1.73 g). Fertilizer treatments were 125 kg chicken manure plus 4.1 kg diammonium phosphate (18-46-0) ...
Biomass and reproductive states of Gracilaria heteroclada Zhang et Xia collected from Jaro, central Philippines
(Walter de Gruyter, 1996)
Biomass production and reproductive states were investigated to determine the abundance of Gracilaria heteroclada Zhang et Xia at Jaro, central Philippines from March 1990 to February 1991. Biomass of Gracilaria heteroclada ...
The effects of different stocking densities and some abiotic factors on cage culture of Gracilaria sp. (Rhodophyta, Gigartinales)
(Walter de Gruyter, 1992)
Specific growth rates (% day<sup>-1</sup>) and production rates (g m<sup>-2</sup> day<sup>-1</sup>) of Gracilaria sp. reared in net cages on a bamboo floating raft from March 1989 to February 1990 were determined at different ...
Salinity effect on the embryonic development, larval growth and survival at metamorphosis of Placuna placenta Linnaeus (1758)
(Elsevier, 2002)
The effects of salinity on the embryonic development, growth, and survival of D-larvae to plantigrade as well as settling in <i>Placuna placenta</i> were studied. Embryos were developed to D-larvae of shell length (SL) ...
Growth, agar yield and quality of selected agarophyte species from the Philippines
(Walter de Gruyter, 2000)
Three local agarophyte species (Gracilaria firma, Gracilaria sp. and Gracilariopsis bailinae) were grown under controlled outdoor flow-through culture conditions. Growth rates and agar characteristics of the three species ...
Factors affecting the spatio-temporal variability in the production of sandfish Holothuria scabra juveniles in floating hapa ocean nursery systems
(Elsevier, 2021-04)
Hatchery production of the tropical sea cucumber Holothuria scabra or sandfish has been successfully demonstrated in various countries, especially during the past decade. However, the main bottleneck in up-scaling production ...
Seasonal growth, carrageenan properties, and resistance to disease and epiphytic pests between Kappaphycus alvarezii (Rhodophyta) var. tambalang (brown) tissue-cultured and farm-sourced seaweeds
(Springer, 2024-01-08)
Growth performance (specific growth rate [SGR] and biomass yield), carrageenan properties (yield, viscosity, and gel strength), and disease and pest incidence were compared between Kappaphycus alvarezii var. tambalang ...
Evaluation of various leguminous seeds as protein sources for milkfish, Chanos chanos Forsskal, juveniles
(Asian Fisheries Society, 1987)
The nutritive value of four leguminous plant seeds: pigeonpea (Cajanus cajan), mungo (Phaseolus radiatus), kidneybean (Phaseolus vulgaris) and soybean (Glycine max), were evaluated as protein sources for milkfish (Chanos ...
