Reef fish Survey

This survey began in 2006 and was conducted to monitor the marine resources in Hong Kong’s water. The investigation focused on the reef fish inhabiting the eastern water of Hong Kong. The data collected include the diversity, density and sizes of native reef fish. Furthermore, we held numbers of photo exhibition, seminars and species survey in order to raise public awareness on the conservation of reef fish and improve public understanding regarding reef fish.

Survey on seahorse

Seahorses are kinds of precious, small-sized fishes which predominantly live in coastal region. Unfortunately, they have been under tremendous pressure of excessive activity of fishery for the sake of their medical value in Chinese region. According to experienced divers, there was record of seahorse inhabitance in Hong Kong’s water. Spotted seahorse was common to find. Sadly, a considerably large area of seahorse’s natural habitat has been compromised due to the loss of natural shoreline as a result of urban development. In order to understand more about this beautiful creature and their distribution in Hong Kong, ERC together with Ocean Park Conservation Foundation and Green Power initiated a thorough investigation regarding the distribution of seahorses throughout Hong Kong in 2010 and 2011. Although various extends of damage has been found at different habitats where seahorses inhabit, numbers of untouched habitats have been discovered. Photo exhibitions and seminars were held for public education to raise awareness regarding the animal. This survey aimed at discovering the last surviving seahorse’s habitats and thus urge the authority to conserve them in better ways. Meanwhile, we would also like to invite the public to take part in the campaign of conservation.





Ecological research on Sea dragons

Sea dragons and seahorses belong to the same family – Syngnathidae, yet they are not similar. Sea dragons were believed to possess similar medical value as seahorses, and for the sake of this sea dragons are often hunt excessively instead of seahorses. Due to their mysterious behavior, we know little about this animal. Hence, attention on this creature remains inadequate in Hong Kong. Investigation on sea dragons was initiated in 2012 to reveal their distribution and other information about them. We would like to pay more attention on overlooked species such as sea dragons and begin conservation before being too late.





Sea weed bed Scouting

Sea weed bed provides fundamental elements such as food, shelter, breeding ground and nursery to many marine lives. In addition, it plays essential role in the cycle of nutrients in the ocean. Therefore, the habitat is considered as the third most valuable ecosystem in the world. However, it’s always been overlooked. According to our research on sea dragons, some of the locations where sea dragons were found were in fact sea weed bed. This indicates sea weed bed is one of the habitats for sea dragons. ERC started the campaign – sea weed bed scouting in 2014 in order to reveal the distribution of sea weed bed in Hong Kong. We like to make use of the data collected in terms of habitat protection. The campaign also includes public education on this particular habitat.

This campaign was sponsored by Airport Authority Hong Kong.





Coastal Search – unveiling the hidden

A dynamic shore is a cradle of colorful lives; it is also a library where we can seek knowledge. Surrounded by the sea, a long natural coastline is a blessing to Hong Kong. Unfortunately, we are depriving such valuable treasure from ourselves by sacrificing it for more land. Some species of animal didn’t survive the drastic change. In order to investigate the coastal biodiversity in Hong Kong and raise public awareness, ERC and Earth Watch co-organized “Coastal Search” in which citizens from range of background were welcome to take part in the campaign as “citizen scientists” to conduct data collection at coastal region.
