Lunar synchronization of spawning in sea bass, Lates calcarifer (Bloch): Effect of luteinizing hormone-releasing hormone analogue (LHRHa) treatment
(Wiley-Blackwell, 1992)
Based on egg collection records, spontaneous spawning activity of sea bass, Lates calcarifer (Bloch), reared in floating net cages followed a semilunar cycle. The peak of multiple spawnings coincided with declining spring ...
The effect of background color and rotifer density on rotifer intake, growth and survival of the grouper (Epinephelus suillus) larvae
(Elsevier, 1996)
Rotifer intake and early growth and survival of Epinephelus suillus larvae were determined in terms of rotifer visibility against the background color of rearing tanks and density. The larvae were stocked at 30 l<sup>−1</sup> ...
Milkfish (Chanos chanos) production and water quality in brackishwater ponds at different feeding levels and frequencies
(Wiley-Blackwell, 1998)
This study evaluated the effects of different feeding levels and frequencies on milkfish (Chanos chanos) growth, feed efficiency, and water quality in brackish water ponds. Milkfish juveniles (average weight, 1 g) were ...
Dietary vitamin C and E supplementation and reproduction of milkfish Chanos chanos Forsskal
(Blackwell Science Ltd, 2000)
Milkfish Chanos chanos Forsskal broodstock (11 years old, average body weight 5.23–5.73 kg) reared in 10-m-diameter by 3-m-deep floating net cages (31–36 fish per cage) at SEAFDEC AQD's Igang Marine Substation in Guimaras ...
Evaluation of the high rate algae pond system for softdrink waste treatment and for fish culture.
(Asean Journals Ltd., 1987)
The High Rate Algae Pond System (HRAP) as secondary treatment for Cola effluents showed potential for reducing both COD load (about 88%) and high pH level (down to pH 7.0 -8.0). The effluent quality improved and can be ...
The sulfide tolerance of milkfish and tilapia in relation to fish kills in farms and natural waters in the Philippines
(Kluwer Academic Publisher, 1998)
Fish kills of milkfish Chanos chanos and tilapia Oreochromis spp. now occur frequently in brackish, marine, and freshwater farms (ponds, pens, and cages) in the Philippines. Aquafarms with high organic load, limited water ...
Expression and purification of a biologically active recombinant rabbitfish (Siganus guttatus) growth hormone
(Elsevier, 2005)
Recombinant rabbitfish growth hormone (rfGH) protein was expressed in Escherichia coli, BL21(DE3) cells. The cDNA encoding the mature protein of rfGH was first cloned in pGEM-Teasy vector and then transferred to pET-3d ...
Growth response of Nile tilapia fry to salinity stress in the presence of an ‘internal reference’ fish
(Blackwell Publishing, 2005)
Growth of three strains of Oreochromis niloticus L. fry exposed to salinity stress in the presence of an internal reference fish were compared. The Central Luzon State University (CLSU) strain was obtained from the Freshwater ...
Multiple gonadal maturation and re-maturation after hormone-induced spawning in bighead carp Aristichthys nobilis Rich.
(San Carlos Publications, University of San Carlos, 1991)
Gonadal maturation and rematuration after hormone-induced spawning in cage-reared female bighead carp Aristichthys nobilis were observed. Percent maturation ranged from 54 to 100% for females and 0 to 40% for males. ...
Hatchery rearing of sea bass Lates calcarifer Bloch
(Science and Technology Information Institute, 1991)
A hatchery rearing scheme for sea bass (Lates calcarifer Bloch) is described. Survival rate from hatching (d0) to harvest (d30) was 34%. Feeding sea bass fry with Chlorella-fed or Selco-enriched instar II Artemia from d19 ...
