In his presentation, Dr. Ransangan outlines the evolution of biotechnology in aquaculture. During which period did the focus shift to the "Genomic and Omics Revolution," where genome sequencing for key species like salmon and tilapia began?

Pre-1900s

2020 - Present

1980 - 1999

2000 - 2010

Dr. Ransangan mentioned several challenges facing biotechnology innovation in aquaculture. Which of the following points did he raise as a significant regulatory and legal barrier?

The lack of public acceptance for consuming any farm-raised fish.

The high cost of implementing high-throughput sequencing technologies.

The absence of unified international regulations for gene-edited and genetically modified aquatic organisms.

The difficulty in isolating environmental DNA (eDNA) from water samples.

What does Dr. Ransangan identify as a primary purpose for applying biotechnology in aquaculture and fisheries ?

To replace all traditional farming methods with fully automated digital systems.

To exclusively focus on the production of genetically modified organisms (GMOs) for export markets.

To improve aquatic organisms and their genetics, enhance production systems, and ensure sustainability.

To increase the use of antibiotics for preventing diseases in fish stocks.
