Effect of light quality and eyestalk ablation on ovarian maturation in Penaeus monodon
Prawns were subjected to the following treatments: blue light, red light, natural light, and natural light plus unilateral eyestalk ablation. Unablated prawns under blue and natural light developed stage III ovaries; under ...
Studies on the chemical composition of a cyanophyte, Spirulina platensis
(Asian Fisheries Society, 1994)
The chemical composition of Spirulina platensis NIES-46 and K-2 strains grown under varios condition of hight intensity and temperature were determined. The dry weight, chla, carotenoid, carbohydrate, protein, and lipid ...
Colour preference and colour vision of the larvae of the giant freshwater prawn Macrobrachium rosenbergii
(Elsevier, 2016)
This paper reports on the innate colour preference and colour vision in the hatchery-reared larvae (10–16 days old, stages IV–VIII) of the giant freshwater prawn Macrobrachium rosenbergii (De Man) based on their response ...
Photoperiod effects on feeding, food conversion, growth, and survival of abalone (Haliotis asinina Linne) during nursery rearing
(Phuket Marine Biological Center, 2001)
Juveniles of Haliotis asinina, 10 mm shell length were subjected to four photoperiodic regimes namely, 6L:18D, OL:24D, diffused 12:12D, and ambient light (12L:12D) serving as control. Juveniles were fed fresh seaweed, ...
Postlarvae density and photoperiod effects on the settlement and metamorphosis of the donkey's ear abalone, Haliotis asinina Linne, 1758
(Phuket Marine Biological Center, 2000)
The effects of photoperiod and density of postlarvae on settlement and metamorphosis of the native abalone, <i>Haliotis asinina</i> were determined in two separate experiments. Abalone larvae were hatched from spontaneously ...
Limit of colour vision in dim light in larvae of the giant freshwater prawn Macrobrachium rosenbergii
(Springer Verlag, 2018)
Colour vision depends on sufficient ambient light and becomes ineffective at a particular low light intensity. It is not known how decapod crustaceans see colour in dim light. In the present study we investigated the colour ...
Effects of continuous lighting on growth and survival of first-feeding larval rabbitfish, Siganus guttatus
(Elsevier, 1988)
The effects of 24-h lighting on feeding, growth and survival of first-feeding larvae of Siganus guttatus were tested. Continuous light gave a higher mean survival (31.69%) with a maximum of 40.50% compared to natural ...
Light color and ovarian maturation in unablated and ablated giant tiger prawn Penaeus monodon (Fabricius)
(Elsevier, 1992)
The effect of light color (green, blue and white fluorescent lights, with natural light as a control) on maturation in intact and eyestalk-ablated Penaeus monodon was tested in 12-m<sup>3</sup> broodstock tanks. Size and ...
A fundamental study on the behavior of milkfish fry for improving the efficiency of traditional fry collecting gear in the Philippines
(Kagoshima University Research Center for the South Pacific, 1980)
The reaction of milkfish fry to miving and stationary nets of different meshes and colors in an experimental tank was determined. The underwater visibility of the nets saw measured and the water filtration in a fry-sweeper ...
Impact of AMPEP on the growth and occurrence of epiphytic Neosiphonia infestation on two varieties of commercially cultivated Kappaphycus alvarezii grown at different depths in the Philippines
(Springer, 2011)
Two varieties of the carrageenophyte Kappaphycus alvarezii (Tungawan, TUNG; and Giant tambalang, GTAM) from Zamboanga Sibugay, Philippines were used to test the efficacy of Acadian Marine Plant Extract Powder (AMPEP) as ...
