Secretary for Environment and Ecology Tse Chin-wan said he hopes to revitalise the city's agriculture and fisheries sectors by harnessing modern technology.

Speaking to RTHK to mark his third year within Chief Executive John Lee's administration, Tse said that his bureau has dedicated significant effort over the past three years towards this goal.

The minister explained that urban development has historically marginalised Hong Kong's agriculture and fisheries, but modern technology now offers a chance for the densely-populated city to revisit these industries.

"Hong Kong currently has four designated fish farming areas covering nearly 600 hectares. These areas will not use traditional methods but will instead employ new deep-sea cage farming techniques with modern computer controls," Tse said.

"This method is often referred to as marine ranching in other countries, and we see it as a very effective approach.

"We have already specified these areas, and we are currently inviting tenders to see if some fishermen can form cooperatives or collaborate with enterprises to develop this work."

Looking ahead, Tse said authorities have set an “ambitious” target of boosting both the volume and value of Hong Kong's aquaculture tenfold within 15 years.
