Source: AFCD 7.14 Figure Chinese White Dolphins Sightings reclamation works, including the marine fish culture zone at Ma Wan and capture fisheries in the North Western WCZ. Based on preliminary water quality modelling results, construction activities are not expected to result in any significant impact on the culture fisheries at Ma Wan Fish Culture Zone. However, the permanent loss of water body would affect fisheries resources and fishing operations, as the proposed reclamation area currently supports a medium-low fisheries production. The permanent loss in fisheries production is preliminarily estimated to be around 0.08% of Hong Kong’s yearly production (58,700-117,400 kg loss). The mechanism for compensation for capture and culture fisheries impacted by reclamation and/ or construction works is well established. Should Option 2 be pursued, further discussions with the Government and the affected parties would be required. Indo-Pacific Humpback Dolphin Potential impact on the Indo-Pacific humpback dolphin (Sousa chinensis), or Chinese White Dolphin (CWD), is another important issue. The local population of dolphins in Hong Kong waters is estimated to be about 100 – 200 individuals, depending on the time of year27. The Agriculture, Fisheries and Conservation Department’s (AFCD) current database (see Figure 7.14) on CWD has been reviewed. The review identified that CWDs are widely distributed throughout northwest Lantau, northeast Lantau, west Lantau and southwest Lantau, while they are rarely observed in the Note: Density of Chinese white dolphins with corrected survey effort per sq.km. in waters around Lantau Island, using data collected during 2002-2009.
