Survival, growth and production of Penaeus monodon Fabricius at different stocking densities in earthen ponds with flow-through system and supplemental feeding.
(Fisheries Research Society of the Philippines, 1981)
Penaeus monodon juveniles (P<sub>53</sub>-P<sub>54</sub>, 0.45 g) were stocked in 200 m<sup>2</sup> earthen ponds with water exchange rate of 5-10% daily, and reared for 3.5 months. Stocking density levels of 2.5, 5.0, 10 ...
Changes in plasma osmolality and chloride concentration during abrupt transfer of milkfish (Chanos chanos) from seawater to different test salinities
(Elsevier, 1988)
Milkfish juveniles (40, 120 or 260 g) were acclimated to 32 ppt seawater, then abruptly transferred to water with salinities of 0, 16, 32 (control) or 48 ppt. Blood samples were taken 0, 1, 2, 3, 5, 7 or 14 days after ...
Supplemental feeding of Penaeus monodon juveniles with diets containing various levels of defatted soybean meal
(Elsevier, 1990)
Varying levels of defattedsoybeanmeal DSM (15, 25, 35, 45 and 55%) in supplementaldiets with approximately 40% crude protein and 10% crude fat were fed to tiger prawn juveniles in 1 m×1 m×1 m net cages set on the bottom ...
Effect of tagging on maturation and survival of ablated Penaeus monodon in painted and unpainted tanks
(San Carlos Publications, University of San Carlos, 1989)
A study was conducted to determine the effects of tags and tank color on reproductive performance and survival of pond-reared Penaeus monodon after eyestalk ablation. In 1986, the best over-all reproductive performance was ...
Natural spawning, egg and fry production of milkfish, Chanos chanos (Forsskal), broodstock reared in concrete tanks
(Blackwell Publishing, 1994)
Gonadal maturation, rematuration, and spawning of nine- (1982 stock) and ten-year-old (1981 stock) milkfish reared in 150 and 200 m<sup>3</sup> concrete tanks were observed in 1990 and 1991. From 23 September to 9 November ...
Growth, survival and feed conversion of Nile tilapia fingerlings fed diets containing Bayo-n-ox, a commercial growth promoter
(Society of Israeli Aquaculture and Marine Biotechnology, 1991)
A feeding experiment was conducted to determine the effect of a commercial growth promoter, Bayo-n-ox, on Nile tilapia fingerlings (mean initial weight 3.6 g). After 6 weeks, the weight gain of fish given 25 mg Bayo-n-ox/kg ...
Effects of DHA-enriched live food on growth, survival and incidence of opercular deformities in milkfish (Chanos chanos)
(Elsevier, 2001)
The use of commercial enrichers to improve the nutritional quality of live food in larviculture of milkfish was investigated. Fish were either fed rotifers cultured on Chlorella sp. and newly hatched Artemia nauplii (Control, ...
A preliminary study on the protein requirements of Chanos chanos (Forskal) fry in a controlled environment
(Elsevier, 1979)
Milkfish (Chanos chanos) fry with an average weight of 40 mg per fish were stocked in 60-l wooden-glass aquaria filled with 30 l of filtered sea water with a salinity of 32–34 p.p.t. and a temperature of 25–28°C. They were ...
Growth response of cultured larvae of silver therapon Leiopotherapon plumbeus (Kner, 1864) in outdoor tanks in relation to fertilizer type and fish density
(Wiley, 2016)
This study evaluated the effects of fertilizer type and fish density on early growth and survival of silver therapon Leiopotherapon plumbeus (Kner, 1864) larvae reared in outdoor tanks. In the first experiment, larvae (1.92 ...
Effect of salinity on survival of Metapenaeus anchistus juveniles and subadults
(University of the Philippines in the Visayas, 1997)
Survival of Metapenaeus anchistus (De Man) juveniles and subadults at 5, 15, 25, 35 (control) and 45 ppt salinity levels was determined and compared. Salinity levels lower than 35 ppt level were prepared by diluting pure ...
