Proteus mirabilis (MJA 2.6S) from saline-tolerant tilapia exhibits potent antagonistic activity against Vibrio spp., enhances immunity, controls \(\mathsf{NH_3}\) levels and improves growth and survival in juvenile giant tiger shrimp, Penaeus monodon
(Wiley, 2022-08-10)
Of several isolates from saline-tolerant tilapia exhibiting anti-vibrio activity, an isolate that demonstrated inhibitory activity with the biggest zone of inhibition against the shrimp pathogens, Vibrio harveyi and V. ...
Molluscan aquaculture in the Philippines: A review
(Springer, 2023-04-25)
Molluscs are among the most valuable resources of the Philippines, an archipelagic country of 7,107 islands bounded by 36,000 km of coastline and 26.6 million ha of coastal waters. In 2020, production from mussels and ...
Biofloc-based nursery production system: Heeding the call towards a sustainable shrimp culture industry in the Philippines
(International Network for Natural Sciences, 2022)
The increasing global population resulted in intense pressure on the food production sectors to meet the rise in food demand. The aquaculture industry, which is one of the major food production sectors, provides opportunities ...
Developing a self-sufficient Philippine milkfish industry through value chain analysis
(Elsevier, 2021-02-15)
The Philippine milkfish industry has been dependent on the importation of juveniles for grow-out ever since the decline of wild fry catch and with inadequate supply from local hatcheries. However, self-sufficiency is ...
Ice-Ice disease: An environmentally and microbiologically driven syndrome in tropical seaweed aquaculture
(Wiley, 2022-01)
Seaweeds account for nearly 30% of global aquaculture production by volume, and their cultivation provides important opportunities for employment and wealth generation, particularly in rural coastal communities. Eucheumatoids ...
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....
Microbial diversity assessment in milkfish culture ponds
(Sciencedomain International, 2020-02)
Aims: To determine bacterial diversity in milkfish culture ponds that contain different life-cycle stages of the milkfish (pond A: fry, pond B: juveniles and pond C: adults) by DNA sequence analysis of organisms and compare ...
Utilization of a portable glucometer for the measurement of tissue glucose as a stress indicator in ornamental fish
(Bioflux (Bioflux SRL), 2021)
The stress response in vertebrates is determined by measuring cortisol production following acute or chronic exposure to various environmental stimuli. Cortisol assays as responses to stressful events are done on blood ...
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 ...
Aquaculture governance: Five engagement arenas for sustainability transformation
(Elsevier, 2023-12)
A greater focus on governance is needed to facilitate effective and substantive progress toward sustainability transformations in the aquaculture sector. Concerted governance efforts can help move the sector beyond fragmented ...
