Effect of dietary organic acid salts, potassium diformate and sodium diformate on the growth performance of male Nile tilapia Oreochromis niloticus
The effect of two organic acid salts on the production performance of juvenile male Nile tilapia Oreochromis niloticus were studied in two separate experiments. In the first trial the fish (initial size: 7.84kg) were fed ...
Embryonic development of the Caridean prawn Macrobrachium mammillodactylus (Crustacea: Decapoda: Palaemonidae)
(Taylor & Francis, 2014)
The freshwater knob-tooth prawn Macrobrachium mammillodactylus is a commercially exploited species in the Philippines. To study the biology of this species, broodstock from the wild was collected, transported to the ...
Net mesh size affects production of giant freshwater prawn Macrobrachium rosenbergii cultured in lake-based cages
(Wiley, 2013)
Cage culture of freshwater prawns in open waters is prone to the entry of predators and competitors that particularly hamper production. This study was conducted to determine how smaller net mesh sizes to reduce entry of ...
Cage culture of the Pacific white shrimp Litopenaeus vannamei (Boone, 1931) at different stocking densities in a shallow eutrophic lake
(Blackwell Publishing, 2009)
Postlarvae of Litopenaeus vannamei were acclimated and stocked in lake-based cages at the following stocking densities: 10, 20, 30 and 40 shrimp m<sup>−2</sup>. Another set of shrimp was stocked in concrete tanks as reference ...
Culture of Macrobrachium rosenbergii (De Man 1879) in experimental cages in a freshwater eutrophic lake at different stocking densities
(Blackwell Publishing, 2007)
Macrobrachium rosenbergii (de Man 1879) juveniles (0.4 g) were cultured in experimental cages (L × W × H: 2.5 × 1 × 1 m) in Laguna de Bay, the largest lake in the Philippines. The following stocking densities at four ...
Uptake and elimination of inorganic mercury and selenium by minnows Phoxinus phoxinus
(Elsevier, 1988)
Minnows were kept in aquaria containing filtered water dosed with measured amounts of mercury as mercuric chloride and selenium as sodium selenate. Fishes exposed to selenium in combination with mercury showed significantly ...
Tissue distribution of mercury and selenium in minnows, Phoxinus phoxinus
(Springer Verlag, 1990)
The protective effect of selenium against mercury toxicity has been extensively demonstrated in a number of studies (Burke eta]. 1977; Kasuya 1976). Since mercury uptake is not always diminished by the presence of selenium ...
Uptake and elimination of iodine-131 by the freshwater clam Corbicula manilensis Philippi from water
(College of Arts and Sciences, University of the Philippines, 1988)
Whole body uptake of Iodine-131 by the freshwater clam, Corbicula manilensis, from contaminated water was followed using NaI scintillation counter. The bioaccumulation factor (BF) exclusive of shell was 5.44. The degree ...
Survival and heavy metal accumulation of two Oreochromis niloticus (L.) strains exposed to mixtures of zinc, cadmium and mercury
(Elsevier, 1994)
Two Nile tilapia strains of Oreochromis niloticus (L.) (Cichlidae, Teleostei) fingerlings were exposed to mixtures of zinc, cadmium and mercury. The two strains used were Chitralada or NIFI (originally from the National ...
Skip feeding as an alternative strategy in the production of Nile tilapia Oreochromis niloticus (Linn.) in cages in selected lakes in the Philippines
(College of Agriculture, University of the Philippines Los Baños,, 2012-12)
Many inland water bodies in the Philippines are currently used for fish cage culture. Inappropriate practices including feed management in aquaculture results not only in the degradation of water quality but also in economic ...
