(Taylor & Francis, 2001)Gonadal maturation, spawning, fecundity and timing of reproduction of the snail Cerithidea cingulata in a brackish water pond in Molo, Iloilo, Philippines, are described. Snails 4–41 mm in shell length were sampled ... -
The seasonality and economic feasibility of cultivating Kappaphycus alvarezii in Panagatan Cays, Caluya, Antique, Philippines
(Elsevier, 2001)Vegetative thalli of brown and green Kappaphycus alvarezii were cultivated in Panagatan Cays, Caluya, Antique, Philippines, over 60- and 90-day periods using hanging-long line (HL), fixed off-bottom (FB), and hanging ... -
Live food production in Japan: recent progress and future aspects
(Elsevier, 2001)Techniques to culture rotifers at high-density (2000 to 20 000 ind./ml) have been developed by utilizing condensed phytoplankton products. Many public hatcheries in Japan have introduced automated systems for culturing and ... -
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, ... -
Use of GABA to enhance rotifer reproduction in enrichment culture
(Blackwell Publishing, 2001)Gamma-aminobutyric acid (GABA) has been shown to enhance the reproduction of the rotifer Brachionus plicatilis Muller in stressful culture conditions. During the enrichment of rotifers for feeding to marine fish larvae, ... -
Grow-out culture of tropical abalone, Haliotis asinina (Linnaeus) in suspended mesh cages with different shelter surface areas
(Kluwer Academic Publishers, 2001)This study investigated the effects of shelter surface area (SSA) on the feeding, growth and survival of the donkey-ear abalone, Haliotis asinina reared in mesh cages (0.38×0.38×0.28m) suspended in flow-through tanks (water ... -
Rapid wound healing in African catfish, Clarias gariepinus, fed diets supplemented with ascorbic acid
(Society of Israeli Aquaculture and Marine Biotechnology, 2001)Wound healing in African catfish, Clarias gariepinus, fed diets supplemented with ascorbic acid was studied under laboratory conditions. Fish weighing approximately 80-110 g were stocked in 500 l aquaria in a static water ... -
Use of juvenile instar Diaphanosoma celebensis (Stingelin) in hatchery rearing of Asian sea bass Lates calcarifer (Bloch)
(Society of Israeli Aquaculture and Marine Biotechnology, 2001)The effects of size, dry mass intake and nutritional value of the brackishwater cladoceran, Diaphanosoma celebensis, on the growth and survival of 15-30 day sea bass (Lates calcarifer) larvae reared in a static green water ... -
Luminescent vibrios associated with mortality in pond-cultured shrimp penaeus monodon in the Philippines: Species composition
(Japanese Society of Fish Pathology, 2001)Heavy mortalities due to luminescent vibriosis have been observed among pond-cultured Penaeus monodon shrimp in the Philippines. The species composition of luminescent Vibrio associated with mortalities was determined. A ... -
Occurrence and histopathogenesis of a didymozoid trematode (Gonapodasmius epinepheli) in pond-reared orange-spotted grouper, Epinephelus coioides
(Elsevier, 2001)A didymozoid trematode encapsulated in the gills of orange-spotted grouper, Epinephelus coioides Hamilton, was observed in October 1997 and September 1999 among pond-reared fish in the Philippines. Capsule prevalence was ... -
Effect of dietary phosphorus and vitamin D3 on phosphorus levels in effluent from the experimental culture of rainbow trout (Oncorhynchus mykiss)
(Elsevier, 2001)Excessive phosphorus (P) levels in aquaculture effluents violate federally mandated limits and pose a serious threat to the freshwater environment. In rainbow trout culture, effluent P probably originates as fecal and ... -
Effect of dietary protein and lipid levels and protein to energy ratios on growth, survival and body composition of the mangrove red snapper, Lutjanus argentimaculatus (Forsskal 1775)
(Wiley-Blackwell, 2001)The approximate levels of dietary protein and energy that would sustain good growth and survival of the mangrove red snapper Lutjanus argentimaculatus (Forsskal) were determined in two feeding experiments. In the ... -
Dietary phosphorus requirement of juvenile milkfish, Chanos chanos (Forsskal)
(Blackwell Publishing, 2001)Seven isocaloric and isonitrogenous diets with graded levels of monopotassium phosphate to yield total phosphorus levels of 0.28 (no P supplementation), 0.43, 0.58, 0.73, 0.88, 1.03 and 1.18% were prepared and fed to five ... -
Culture and economics of wild grouper (Epinephelus coioides) using three feed types in ponds
(Elsevier, 2001)The performance of wild Epinephelus coioides juveniles was compared by feeding with live tilapia juveniles, fish by-catch, and formulated diet for 5 months in grow-out ponds. To minimize cannibalism, the groupers were ... -
Reproductive performance of hatchery-bred donkey's ear abalone, Haliotis asinina, Linne, fed natural and artificial diets
