An assessment of algal growth in net cages in Laguna Lake
(Fisheries Research Society of the Philippines, 1981)
Quantitative determination of the algal population, in terms of cells/ml and biomass/ml, was conducted during the first month of growing P. monodon postlarvae in Laguna Lake. Algae were sampled from each side of net cages ...
Biological evaluation of phytoplankton (Chlorella sp., Tetraselmis sp. and Isochrysis galbana) as food for milkfish (Chanos chanos) fry.
(Elsevier, 1984)
Phytoplankton cultures of Chlorella sp., Tetraselmis sp. and Isochrysis galbana were used alone as feed to rear separate batches of newly caught milkfish (Chanos chanos) fry (about 21 days old). Ultrastructural studies of ...
Investigations on the feeding behavior of juvenile milkfish (Chanos chanos Forsskål) in brackishwater lagoons on South Tarawa, Kiribati
(Verlag Natur und Wissenschaft, 2002)
This study evaluated the feeding behavior of the milkfish (Chanos chanos Forsskål) in extensively managed brackishwater lagoons on South Tarawa, Kiribati (Central Pacific) in August 1998. Feed intake, dietary overlap, fish ...
Fry-to-fingerling production of Tilapia nilotica in aquaria using phytoplankton as natural feed
(University of the Philippines at Los Baños, 1982)
Two experiments were conducted to demonstrate the efficiency of phytoplankton as natural feed in fry-to-fingerling production of Tilapia nilotica . In the first experiment, growth and survival rates of fry given a sustained ...
Efficiency of Chlorella sp. and Tilapia hornorum in controlling the growth of luminous bacteria in a simulated shrimp culture environment
(Elsevier, 2005)
This study clarifies the effect of green water from Chlorella sp., Tilapia hornorum and the combination of the two organisms on the growth of luminous bacteria in a simulated shrimp culture environment. Results showed that ...
Effects of low nitrogen-phosphorus ratios in the phytoplankton community in Laguna de Bay, a shallow eutrophic lake in the Philippines
(Springer Verlag, 2004)
The effects of low nitrogen-phosphorus ratios on microalgae from a large eutrophic freshwater lake in the Philippines were investigated. Natural microalgal populations from Laguna de Bay, the largest lake in the Philippines, ...
Anti-luminous Vibrio factors associated with the ‘green water’ grow-out culture of the tiger shrimp Penaeus monodon
(Elsevier, 2005)
The ability of the “green water” grow-out culture of the tiger shrimp Penaeus monodon to prevent outbreaks of Luminous Vibriosis was investigated by screening associated isolates of bacteria, fungi, phytoplankton and fish ...
The macronutrient composition of natural food organisms mass cultured as larval feed for fish and prawns
(Society of Israeli Aquaculture and Marine Biotechnology, 1990)
The macronutrient composition of natural food organisms that are mass cultured as feed for the larval stages of fish and prawns in the SEAFDEC Aquaculture Department was determined by chemical analysis. The food organisms ...
Winter distribution of phytoplankton and zooplankton around some sandbanks of the Belgian coastal zone
(Oxford University Press, 1998)
The distribution of phytoplankton and zooplankton around three sandbanks (Gootebank, Westhinder and Buitenratel sandbank) off the Belgian Coast was investigated in February 1994. The abundance of phytoplankton taxa was ...
Accumulation and tissue distribution of radioiodine (131I) from algal phytoplankton by the freshwater clam Corbicula manilensis
(Springer Verlag, 1991)
Radioactive wastes discharged from establishments involved in the use of radioisotopes such as nuclear powered industries, tracer research and nuclear medicine are a potential public health hazard. Such wastes contain ...
