“President Joko Widodo said that Indonesia has to be the World Maritime Axis Country. Therefore, Indonesia has the responsibility of managing abundant fisheries resources, “ Dean of Faculty of Fisheries and Marine Sciences, Universitas Airlangga Prof. Dr. Mirni Lamid MP remarked during opening of the first annual International Fisheries and Marine Biotechnology Seminar that was held via Zoom on Tuesday, September 8, 2020.
The webinar on Recent Advance on The Sustainable Aquaculture, Fisheries, and Marine Biotechnology invited four international keynote speakers, Prof. Dr. Sonia Ventura of Portugal’s Universidade de Aveiro; Prof. Albert Linton Charles of National Pingtung University of Science and Technology Taiwan; Assoc. Prof. Dr. Nurul Huda from Universiti Malaysia Sabah Malaysia; and Assist. Prof. Md. Asaduzzaman from Chittagong Veterinary and Animal Sciences University Bangladesh.
Each keynote speaker presented on a different topic of discussion. Prof. Albert Linton Charles explained about his research, Characterization Of Freeze-Dried Microencapsulation Tuna Fish Oil With Arrowroot Starch And Maltodextrin. Tuna fish oil can be packaged in capsules made from arrowroot starch and Maltodextrin, then it was compared with fish oil content packaged from 2 different ingredients.
“These are the food processing challenges of fish oil for consumption,” said Prof. Albert.
Next, Prof. Nurul Huda explained the potential content of collagen in marine life which can be used as an ingredient for wound healing. Fish byproducts are in high demand for the production of collagen and its hydrolyzates, which act as wound healing factors. Fish collagen is found in the skin, bones, fins and scales.
“Meanwhile, hydrolyzed collagen (peptides) has been found in jellyfish, Allaska Pollock fish skin, tilapia, salmon and haddock,” he explained.
“Most of the fish potentials mentioned above are sub-tropical fish, but it would be nice for us (researchers in tropical regions, ed) to explore the potential fish which can be used for wound healing,” he added.
Meanwhile, from Dr. Md Asaduzzaman who examined the development of muscle tissue in fish, revealed that as the fish age, muscle tissue increases through 2 cell mechanisms; Hyperplasia and Hyperthrophy. In mammals, however, as we age, muscle mass decreases.
“Fish is the right model for the development and growth of muscle tissue, aging, and the regeneration mechanism,” he said.
The last speaker, Prof. Dr. Sonia Ventura explained the development of marine biota processing technology, especially for red algae. Red algae contain phycoerythrin which functions as an antioxidant, antidiabetic, and anti-cancer.
“It takes several processes to extract phycoerythrin, through extraction and purification using the thermo responsive system ,” concluded Prof. Sonia.
