Internet use, eHealth literacy and fear of COVID-19 among nursing students in the Philippines
No full textThe COVID-19 outbreak situation brought into focus not only the safety but also the mental wellbeing of nursing students. At present, the level of fear of COVID-19 and associated factors among nursing students in the Philippines is not well understood. This cross-sectional online survey determined the relationship between Internet use and eHealth literacy with fear of COVID-19. One thousand three hundred and sixty-seven (n=1,367) answered an online survey using the adopted eHealth Literacy Scale (eHEALS), and Fear of COVID-19 Scale (FCV-19S) administered from May 1 to 15, 2020. Descriptive statistics, tests for differences, and correlational analysis were performed. Results indicated that the composite score of the FCV-19S was 3.65, indicating moderate to high levels of fear. Fear of COVID-19 significantly differed based on sex, year level, and location. A significant inverse relationship was found between the average daily use of the Internet and fear of COVID-19. On the other hand, no significant association was noted between eHealth literacy and fear of COVID-19. The first wave of the COVID-19 outbreak has resulted in a far-reaching impact on nursing students' psychological wellbeing. This study highlights the value of the Internet and its use during the outbreak may not always lead to higher fear related to COVID-19. Nursing schools may need to create strategies to promote regulated and responsible Internet use, address students' mental health concerns and develop interventions to respond proactively to mitigate or reduce fear among nursing students during the pandemic
Developing technologies for giant grouper (Epinephelus lanceolatus) aquaculture in Vietnam, the Philippines and Australia
No full textThis project established a sustainable aquaculture industry for giant grouper in Vietnam and the Philippines through the development of captive breeding and larval-rearing techniques.
Captive breeding innovations and larval-rearing techniques, developed through a collaborative Fisheries project, are sustaining the aquaculture industry for giant grouper in Vietnam and the Philippines.
Groupers are vital to the live reef food-fish trade in South-East Asia, and the giant grouper is a high-value, fast-growing species with significant aquaculture potential.
Establishing a sustainable giant grouper aquaculture industry is a high priority for the region, but research is hampered by the high level of investment required to hold and maintain giant grouper broodstock. Lack of commercial production is also due to limited knowledge about the giant grouper’s maturation and spawning behaviour, and low larval survival
Identification of a chromosomally-encoded sucrose operon-like gene cluster in Vibrio parahaemolyticus strain PH05 isolated from Negros Island, Philippines
Get PDFThe ability of bacteria to metabolize a wide variety of carbon sources has been known to aid in their ability for efficient colonization. Vibrio parahaemolyticus, a known aquatic pathogen has been reported to have the ability to metabolize a number of carbohydrates including D-glucose, D-galactose, L-arabinose, D-mannose, and D-ribose to name a few. Classical isolation of V. parahaemolyticus from other members of the family Vibrionaceae relies on its carbon utilization pattern. Conventionally, V. parahaemolyticus lacks the ability to utilize sucrose and this has been the basis for its isolation using the Thiosulfate-citrate-bile salts-sucrose (TCBS) agar. Reports of V. parahaemolyticus having the ability to utilize sucrose have been presented yet there is paucity of information and detailed study on this phenotype. In this study, we report the V. parahaemolyticus strain PH05 that has the ability to metabolize sucrose. Phenotypic and genotypic characterization of this V. parahaemolyticus strain isolated from Negros Island, Philippines, revealed that V. parahaemolyticus strain PH05 is atypical appearing yellow on TCBS agar plates. It is capable of utilizing sucrose, unlike the majority of V. parahaemolyticus isolates. Genome analyses of this strain revealed the presence of a chromosomally encoded sucrose operon-like gene cluster encoded in chromosome 2 with the following sucrose-utilization associated genes: scrY, ccpA, treP, scrK, and scrB genes coding for sucrose porin, catabolite control protein A, PTS System sucrose-specific EIIBC component, fructokinase, and sucrose-6-phosphate hydrolase. The mode of transmission of these genes to V. parahaemolyticus strain PH05 is still unknown. However, the presence of insertion sequences (IS) and phage elements in the same chromosome suggests horizontal gene transfer events. Taken together, our results point to the possibility that acquired sucrose utilization genes may contribute to the fitness of V. parahaemolyticus strain PH05 in the environment.This work was supported by a Department of Science and Technology, Philippine Council for Agriculture, Aquatic and Natural Resources Research and Development (DOST-PCAARRD) grant to CPS, EAA, LDD, and a DOST Science Education Institute fellowship to CADM and RMM
Exploring, harnessing and conserving marine genetic resources towards a sustainable seaweed aquaculture
No full textSeaweed cultivation is the fastest‐growing aquaculture sector, with a demonstrable potential to drive development in some of the poorest coastal populations worldwide. However, sustainable exploitation, fair access and equitable benefits from marine genetic resources, such as seaweeds have yet to be fully realised. Patchy fundamental knowledge on the genetic diversity and metabolic potential of algae limits their exploitation; scant practical skills and low investment in breeding restricts germplasm availability and the Nagoya protocol has only partially remediated insufficient governance. Further developments and the addressing of knowledge gaps in relation to biosecurity, breeders’ rights and conservation of genetic resources are needed for progress.CMMG, JaB, RCS, PEL, IC, EJCC, VM, GW, VLM, FEM, JuB were supported by the United Kingdom Research and Innovation–Global Challenges Research Fund (UKRI‐ GCRF) ‘GlobalSeaweedSTAR' Programme (Grant No. BB/P027806/1), which also supported RVD through the research fund GSS/RF/015.

Biofloc technology (BFT): A promising approach for the intensive production of ornamental fish
No full textBiofloc technology (BFT) is an approach in the rearing of fish and shrimp as a means to support intensive culture, maintain optimum water quality, recycle the nutrients and reduce feed costs. The technology is primarily based on the principle of recycling nitrogenous wastes into microbial biomass that can be assimilated by the cultured animals as feeds or facilitates in maintaining good water quality. The rearing of larvae and juveniles of ornamental fish is confronted with issues on low survival rate, poor water quality and high incidence of diseases. These problems can be mitigated through the use of biofloc technology. From a number of studies reviewed, BFT offers a viable approach in ensuring sustainable production of ornamental fish. The benefits of using this technology include enhancement of water quality by reducing the levels of nitrogenous wastes, efficient feed conversion resulting in better growth and reduction in production costs and better immune response that will enable the fish to have higher resistance against infectious diseases.This work was partly supported by the University of San Agustin Professorial Chair Research Grant titled, “Gut Microbiome: A Potential Source of Probiotic Candidates for Ornamental Fish” awarded to CMA Caipang.

Trends in the major aquaculture food fish production in the Philippines
Get PDFPredictability of food fish derived from the aquaculture sector is a pragmatic concern for the society at large. In this paper, the trend in aquaculture production is presented, with emphasis on the two major food fish species, milkfish and tilapia. Particular interest is on the assessment of observed over-all decline on the rate of output generation in the recent years and its major cause. Accordingly, the impacts on supplies and estimates on the needed catch-up growth rates for the milkfish and tilapia sub-sectors (excluding municipal inland fisheries) are explained. Adjustments currently being implemented by the milkfish and tilapia farming sub-sectors are discussed. Finally, selected prospects related to farming site expansion, emerging farmer-oriented information needs and quality of critical inputs are discussed. In the context of this important occasion, the International Workshop on the Promotion of Sustainable Aquaculture, Aquatic Animal Health and Resource Enhancement in Southeast Asia (SARSEA), interventions offered herein are deemed relevant to the greater Southeast Asian region as well
