Elemental sulfur in the gills of the mangrove mud clam Anodontia edentula (Family Lucinidae)
(National Shellfisheries Association, 2000)
Different sizes of the mangrove mud clam <i>Anodontia edentula</i> were collected from the mangroves in Brgy. San Roque in Estancia, Iloilo, central Philippines, and the mantle, gill, and foot tissues were analyzed for ...
Nursery rearing of Penaeus monodon (Fabricius) using suspended (hapa) net enclosures installed in a pond
(Elsevier, 1993)
The use of suspended (hapa) nets as nursery enclosures for shrimp fry was tested. In the first trial, four stocking densities (72, 144, 288, and 432 fry m<sup>−3</sup>) of P. monodon fry (PL<sub>20</sub>, body weight = 8 ...
Notes on the completion of the life cycle of Penaeus japonicus in captivity in the Philippines
(Science and Technology Information Institute, 1991)
Penaeus japonicus nauplii from wild spawners were reared up to the early postlarval stage (PL20) in 12-t concrete tanks. A survival rate of 13-15% was obtained. Hatchery-reared postlarvae were restocked in concrete tanks ...
Genetic diversity of wild and cultured black tiger shrimp (Penaeus monodon) in the Philippines using microsatellites
(Elsevier, 2001)
Six microsatellites were used to study (1) the genetic diversity of wild <i>Penaeus monodon</i> shrimp from four geographic regions (Palawan, Quezon, Capiz and Negros Occidental-W) in the Philippines, and (2) its association ...
The financial feasibility of small-scale grouper aquaculture in the Philippines
(International Association of Aquaculture Economics and Management (IAAEM), 2004)
This paper presents the results of an economic analysis of the aquaculture of two species of grouper E. coloides (orange‐spotted grouper, green grouper, red‐spotted grouper) and E. malabaricus (malabar grouper, black‐spotted ...
Nitrogen and phosphorus utilization in the cyanobacterium Microcystis aeruginosa isolated from Laguna de Bay, Philippines
(Springer Verlag, 2007)
Phytoplankton supports fisheries and aquaculture production. Its vital role as food for aquatic animals, like mollusks, shrimp, and fish cannot be overemphasized. Because of its contribution as a food source for fish, the ...
Accumulation and depletion of oxytetracycline (OTC) and oxolinic acid (OXA) in Pompano, Trachinotus blochii
(European Association of Fish Pathologists, 2022-09-03)
Accumulation and depletion including withdrawal period for oxytetracycline (OTC) and oxolinic acid (OXA) in pompano (<i>Trachinotus blochii</i>) were determined following oral administration. Pompano were cultured in 250-L ...
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 ...
Motile aeromonads recovered from tilapia (Oreochromis niloticus) cultured in earthen ponds in the Philippines: Assessment of antibiotic susceptibility and multidrug resistance to selected antibiotics
(AquacultureHub Inc., 2022-07)
A total of 177 motile Aeromonas spp., comprised of A. hydrophila (n=162) and A. sobria (n=15), isolated from the water, sediment, gills and intestines of tilapia collected from the grow-out culture earthen ponds in the ...
Genomic analysis of Vibrio harveyi strain PH1009, a potential multi-drug resistant pathogen due to acquisition of toxin genes
(Elsevier, 2023-03-25)
In has increasingly been observed that viral and bacterial coinfection frequently occurs among cultured shrimp and this coinfection could exacerbate the disease phenotype. Here, we describe a newly discovered bacterial strain, Vibrio harveyi PH1009 collected from Masbate Island, Philippines that was found to be co-infecting with the White Spot Syndrome virus a sample of black tiger prawn, Penaeus monodon. The genome of V. harveyi PH1009 was sequenced, assembled, and annotated. Average Nucleotide identity calculation with Vibrio harveyi strains confirmed its taxonomic identity. It is a potential multi-drug and multi-heavy metal resistant strain based on the multiple antibiotic and heavy metal resistance determinants annotated on its genome. Two prophage regions were identified in its genome. One contained genes for Zona occludens toxin (Zot) and Accessory cholera toxin (Ace), essential toxins of toxigenic V. cholerae strains apart from CTX toxins. Pan-genome analysis of V. harveyi strains, including PH1009, revealed an “open” pan-genome for V. harveyi and a core genome mainly composed of genes necessary for growth and metabolism. Phylogenetic tree based on the core genome alignment revealed that PH1009 was closest to strains QT520, CAIM 1754, and 823tez1. Published virulence factors present on the strain QT520 suggest similar pathogenicity with PH1009. However, PH1009 Zot was not found on related strains but was present in strains HENC-01 and CAIM 148. Most unique genes found in the PH1009 strain were identified as hypothetical proteins. Further annotation showed that several of these hypothetical proteins were phage transposases, integrases, and transcription regulators, implying the role of bacteriophages in the distinct genomic features of the PH1009 genome. The PH1009 genome will serve as a valuable genomic resource for comparative genomic studies and in understanding the disease mechanism of the Vibrio harveyi species....
