“Gracilariopsis Heteroclada protein concentrate as soybean meal replacement in the diet of black tiger shrimp (Penaeus monodon) post larvae” was cited as the Best Research Presentation Award in the Student Oral Presentation (graduate level) category during the gathering of aquaculture and fisheries experts held in Iloilo City.
One oral presentation and two posters of the graduate students from the College of Fisheries and Ocean Sciences (CFOS) won the student research competition at the 12th Asian Fisheries and Aquaculture Forum (AFAF) held in the Iloilo Convention Center on April 8-12, 2019.
Presented by Carl John Saromines, the study revealed that an extracted protein concentrate from the red microalga, Gracilaripsis heteroclada, can be an alternative protein source to soybean meal of up to 50% replacement level on the growth performance, feed utilization and survival of the black tiger shrimp.
Poster presentations of Angeleca Sumogod and Gene Rose Maquirang were adjudged Best Research Presentation in the poster category (graduate level).
Sumogod presented the findings of her study on the “Extraction and purification of hyaluronic acid (HA) from yellow fin tuna (Thunnus albacares) eyeball.” Utilizing varying extraction methods, incubation periods, digestion times, salt concentrations and ethanol, the study showed the potential of tuna eyeballs in producing HA.
Entitled “Influence of various microalgae on the digestion, clearance and ingestion rates of green mussel Perna viridis pediveliger larvae,” the poster presented by Maquirang assessed three species of microalgae as feed in green mussel. These microalgae were Isochryrsis galbana, Chaetoceros calcitrans and Tetraselmis tetrahele. The study demonstrated that the three microalgae were all digestible and acceptable to the animal. However, I. galbana and C. calcitrans are the best in terms of clearance and ingestion rate.
The 12AFAF was organized by the Asian Fisheries Society (AFS), a scientific society founded by fishery professionals in Asia in 1984, in partnership with the University of the Philippines Visayas (UPV) and the UPV Foundation, Inc. with the theme “Transforming Asian Fisheries and Aquaculture for Sustainable Production and Nutrition.”
Held every three years, the AFAF provides an international platform for distinguished scientists, researchers, managers, and practitioners around the globe to share new knowledge, developments, and innovations as well as tackle various issues and challenges towards sustainable fisheries and aquaculture in the Asia-Pacific region.
The next AFAF will be held in Taiwan.
