Influence of water temperature on induced reproduction of milkfish during the off-season
(Aqua Research Pte Ltd, 2022)
Scientific studies on milkfish’s induced spawning and larval rearing by increasing water temperature in tanks are very limited. In order to increase the production capacity of milkfish fingerlings, a preliminary experiment ...
Microsatellite and mitochondrial haplotype diversity reveals population differentiation in the tiger shrimp (Penaeus monodon) in the Indo-Pacific region
(International Society for Animal Genetics, 2008)
The black tiger shrimp (Penaeus monodon) is an ecologically and economically important penaeid species and is widely distributed in the Indo-Pacific region. Here we investigated the genetic diversity of P. monodon (n = ...
In vitro and in vivo evaluation of the efficacies of commercial probiotics and disinfectant against acute hepatopancreatic necrosis disease and luminescent vibriosis in Litopenaeus vannamei
(Elsevier, 2024-05)
The bioactivities of two commercially available probiotics and one chemical disinfectant were tested against strains of Vibrio parahaemolyticus (VP<sub>AHPND</sub>) and V. harveyi. This study aimed to determine shrimp pathogenic Vibrios' in vitro and in vivo sensitivities to commercial probiotics and a chemical disinfectant. The probiotics and disinfectant were tested first in vitro, followed by the in vivo trials. Results showed that upon administration of probiotics either through diet or adding into the tank water, the survivability of shrimp was increased during challenge with VP<sub>AHPND</sub> and V. harveyi. Also, the disinfectant was tested against the same pathogens and showed positive bactericidal effects at 2500 ppm and 5000 ppm. The present findings suggest that adding probiotics to the rearing water or the shrimp feeds effectively prevents infection by lowering the load of pathogenic bacteria. In comparison, the effectiveness of the disinfectant (PUR) depends on its appropriate concentration and timing of application. It is not only limited to rearing water but is also applicable for decontaminating pond liners, tanks, and other paraphernalia....
Sandfish (Holothuria scabra) as potential reservoir of white spot syndrome virus (WSSV) when co-cultured with black tiger prawn (Penaeus monodon)
(European Association of Fish Pathologists, 2024-03-08)
Since the first occurrence of White Spot Disease (WSD) in 1992, it is still listed as one of the crustacean diseases by the World Organisation for Animal Health in 2022. Horizontal transmission in co-culture systems is one ...
Complete genome sequence of Vibrio parahaemolyticus strain PH1273, isolated from aquacultured shrimp in the Philippines
(American Society for Microbiology, 2023-10-19)
We announce the complete genome sequence of Vibrio parahaemolyticus strain PH1273. This strain was collected from a Penaeus vannamei pond in the Philippines in 2015. Genome analysis revealed that it lacks the gene pirAB ...
Seasonal growth, carrageenan properties, and resistance to disease and epiphytic pests between Kappaphycus alvarezii (Rhodophyta) var. tambalang (brown) tissue-cultured and farm-sourced seaweeds
(Springer, 2024-01-08)
Growth performance (specific growth rate [SGR] and biomass yield), carrageenan properties (yield, viscosity, and gel strength), and disease and pest incidence were compared between Kappaphycus alvarezii var. tambalang ...
Susceptibility of different weight ranges of Epinephelus coioides to piscine nodavirus
(European Association of Fish Pathologists, 2017)
The susceptibility of different weight ranges of orange-spotted grouper (Epinephelus coioides) to piscine nodavirus was studied by experimental infection. Size ranges of 1-2 g, 6-8 g, 10-13 g, 30-60 g, and 90-120 g were ...
Evaluation of various leguminous seeds as protein sources for milkfish, Chanos chanos Forsskal, juveniles
(Asian Fisheries Society, 1987)
The nutritive value of four leguminous plant seeds: pigeonpea (Cajanus cajan), mungo (Phaseolus radiatus), kidneybean (Phaseolus vulgaris) and soybean (Glycine max), were evaluated as protein sources for milkfish (Chanos ...

Detection of betanodaviruses from different organs of broodstocks and wild juveniles of orange-spotted grouper, Epinephelus coioides
(Japan International Research Center for Agricultural Sciences, 2006)
Aquaculture of grouper including orange-spotted grouper suffers losses from viral nervous necrosis (VNN). This disease usually occurs in larval stage resulting in a high rate of mortality. It is conceivable that vertical ...
