It was with great sadness that we learned that our dear friend Professor Sena De Silva passed away on 6 May, 2020. On behalf of the Governing Council, the Chair Dr Yingjie Liu, and the NACA Secretariat, would like to express our sincere condolences to his family. The aquaculture community, and the region, has lost one of its true champions. We, the staff of the NACA Secretariat, will miss Sena. He was not just a colleague, teacher and mentor, he was also our friend.

Potential new species in the Kingdom of Saudi Arabia: Sabaki tilapia (Oreochromis spilurus); Role of fish & fisheries in national nutrition of Pakistan; Success story of first fish farmer in India to be awarded ‘Padma Shri’; Insights into the fishing gear and ichthyofauna of major lentic water bodies of Kashmir Valley; NACA Newsletter.

For the sustainable economic development of Saudi Arabia, the government set up the goals of Vision 2030. In 2030, the Saudi aquaculture industries expect to produce a combined 600,000 tonnes. At present, the total aquaculture production of Saudi Arabia is around 55,000 tonnes. To match the production goal, we need to find some new species to farm. Candidate species should be unique, easy to manage, low cost and have high market demand. The fisheries authority has chosen Sabaki tilapia (Oreochromis spilurus) to be our promotional species. This article describes efforts to establish Sabaki tilapia aquaculture operations in the Kingdom of Saudi Arabia.

The fisheries sector of Pakistan comprises over 290,000 square kilometres of marine waters and 8.6 million hectares of inland water resources including the world’s largest irrigation system and favourable climatic conditions for aquaculture development. Despite these promising circumstances Pakistan stands thirty-third in world fisheries production. This article considers the true fish production potential of Pakistan and makes a comparison with other regional countries that produce more despite having less water resources, e.g. Bangladesh. Considering the ground reality and gaps in fisheries statistics collection, assessment and reporting, the possibility that fish production and consumption are under reported is explored.
