Participation of women in oyster and mussel farming in Western Visayas, Philippines
(Blackwell Publishing, 1995)
This paper provides baseline information on the involvement of women in small-scale coastal aquaculture such as the farming of slipper oyster, Crassostrea iredalei (Faustino 1933), and green mussel, Perna viridis (Linnaeus ...
A simple semi flow-through culture technique for the controlled super-intensive production of Artemia juveniles and adults
(Elsevier, 1992)
A simple semi flow-through Artemia culture unit is described for possible integration in marine fish and shellfish hatcheries as source of a cheap nursery diet. The system does not require the use of feeding pumps and ...
Effects of unilateral eyestalk ablation on ovarian histology and oocyte size frequency of wild and pond-reared Penaeus monodon (Fabricius) broodstock
(Elsevier, 1991)
Effects of eyestalk ablation on ovarian maturation of wild and pond-reared Penaeus monodon were determined to compare their reproductive potential. This was done by counting the oocyte size frequency in four regions of the ...
Assessment of some agarophytes from the coastal areas of Iloilo, Philippines. I. Seasonal variations in the biomass of Gracilaria changii, Gracilaria manilaensis and Gracilariopsis bailinae (Gracilariales, Rhodophyta)
(Walter de Gruyter, 1996)
Monthly biomass (g dwt m<sup>-2</sup>) of Gracilaria changii, G. manilaensis and Gracilariopsis bailinae collected in four different coastal areas of Iloilo, Philippines showed significant differences. Gracilaria changii ...
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 ...
Influence of pyrite oxidation and soil acidification on some essential nutrient elements.
(Aquacultural Engineering Society (AES), 1997)
Influence of soil acidification on some essential nutrient elements was observed experimentally during periodic leaching at 10-day intervals of pyritic soil materials. Pyritic soil in glass columns saturated with distilled ...
Mortalities of pond-cultured juvenile shrimp, Penaeus monodon, associated with dominance of luminescent vibrios in the rearing environment
(Elsevier, 1998)
Severe mortalities due to luminescent vibrios occurred in pond-cultured Penaeus monodon juveniles particularly in the first 45 days of culture. Luminescent vibriosis epizootics led to reduced shrimp production due to ...
Food value of Brachionus plicatilis fed three selected algal species as live food for milkfish, Chanos chanos Forsskal, fry production
(Blackwell Publishing, 1990)
The effects of three selected algal species, Tetraselmis tetrahele, Isochrysis galbana and marine Chlorella sp. on the population growth of Brachionus plicatilis was evaluated after 3, 5 and 7 days of culture. The rotifers ...
Laboratory manipulation of Gracilariopsis bailinae Zhang et Xia (Gracilariales, Rhodophyta)
(Walter de Gruyter, 1997)
Carpospore germination, carposporeling development and tetraspore formation were investigated in Gracilariopsis bailinae Zhang et Xia by manipulating photoperiod, photon flux density, temperature, salinity and nutrients. ...
Effect of growth hormone and γ-aminobutyric acid on Brachionus plicatilis (Rotifera) reproduction at low food or high ammonia levels
(Elsevier, 1999)
Growth hormone (GH, 0.0025 and 0.025 I.U. ml<sup>−1</sup>) and γ-aminobutyric acid (GABA, 50 μg ml<sup>−1</sup>) enhance rotifer population growth in batch cultures. In order to further understand the mechanism of their ...
