Gonadal maturation, fecundity, spawning and timing of reproduction in the mud snail, Cerithidea cingulata, a pest in milkfish ponds in the Philippines
(Taylor & Francis, 2001)
Gonadal maturation, spawning, fecundity and timing of reproduction of the snail <i>Cerithidea cingulata</i> in a brackish water pond in Molo, Iloilo, Philippines, are described. Snails 4–41 mm in shell length were sampled ...
Dietary P regulates phosphate transporter expression, phosphatase activity, and effluent P partitioning in trout culture
(Springer Verlag, 2003)
Phosphate utilization by fish is an important issue because of its critical roles in fish growth and aquatic environmental pollution. High dietary phosphorus (P) levels typically decrease the efficiency of P utilization, ...
Phosphorus utilization in rainbow trout (Oncorhynchus mykiss) fed practical diets and its consequences on effluent phosphorus levels
(Elsevier, 2003)
Excessive dietary phosphorous (P) concentrations in effluents from aquaculture present a major environmental problem. We therefore studied the effect of dietary P and vitamin D<sub>3</sub> on P utilization by rainbow ...
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 ...
Microcystin production during algal bloom occurrence in Laguna de Bay, the Philippines
(Japanese Society of Fisheries Science, 2003)
The amount of microcystin in Microcystis aeruginosa bloom was investigated during the rainy season of 1999 in Laguna de Bay, the Philippines. Bloom samples taken from the West Bay and East Cove stations of the lake were ...
Pathogenicity of the epizootic ulcerative syndrome (EUS)-associated rhabdovirus to snakehead Ophicephalus striatus
(Japanese Society of Fish Pathology, 2001)
The rhabdoviruses isolated from EUS-affected snakeheads in the Philippines was tested for pathogenicity to healthy, naive snakehead Ophicephalus striatus fry, fingerlings and juveniles. Virus exposure of naive snakehead ...
Utilization of feed pea, Pisum sativum, meal as protein source in practical diets for juvenile shrimp, Penaeus monodon
(Elsevier, 2003)
The potential of feed pea meal as an alternative protein source to soybean meal in practical diets for the juvenile tiger shrimp, Penaeus monodon, was assessed in several experiments. Six isonitrogenous diets were formulated ...
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 ...
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 ...
Presence of snapper, seabass, and siganid inhibits growth of luminous bacteria in a simulated shrimp culture system
(Elsevier, 2006)
The antibacterial effect of the presence of Tilapia hornorum against luminous bacteria in shrimp culture has been reported. This study investigates how the presence of commercially valued marine species such as seabass, ...
