Spotted this by chance. A stingray at the ferry pier in Discovery Bay, Lantau. An approaching ferry spooked it and it fled to the rocks under the pier in shallow water. Click here for my page on rays in Hong Kong.

Whale Shark Sighting

Earlier this week an online video of a whale shark in Hong Kong went viral.

Unfortunately there is no specific protection for this species in Hong Kong, so experts are calling on the government to introduce laws to protect whale sharks which are infrequent visitors to Hong Kong waters in the summer months.

The footage was posted by a Lamma Island resident Robert Lockyer, who said the footage was sent to him by one of the fishermen who encountered the shark on Tuesday.

Lockyer said there had been another local sighting on May 22, but he believed it was a different shark at another location.

The fisherman who took the video did not wish for his identity or the location of the sighting to be known.

Relocated Seahorses Missing

Two endangered seahorses which were moved from Lung Mei Beach near Tai Po, to make way for man-made pleasure beach, ca not be found anymore. Whether they survived the move is not known.

The Civil Engineering and Development Department failed to find them during a search in late January.

“We have not located the seahorses but we have not found any bodies either,” said senior engineer Raymond Cheng Kin-man. “We are

confident that they are still alive.”

Trawling Ban Enforced – Man Given Suspended Jail Sentence for Trawling 

A man who illegally used trawling gear for fishing on January 17th 2018 has been convicted and sentenced to two months’ imprisonment suspended for two years and a fine of $4,000 at Kwun Tong Magistrates’ Court on January 18th 2018.

The Agriculture, Fisheries and Conservation Department (AFCD) and the Marine Police mounted an anti-illegal fishing operation in the eastern waters of Hong Kong yesterday, and found a mainland shrimp trawler suspected to be trawling at Ninepin Islands. The vessel was inspected and gear used for trawling was seized on board the vessel. Upon investigation by the AFCD, a male master on the vessel was charged for contravening the Fisheries Protection Regulations by using prohibited fishing gear. He was convicted and sentenced.

The ban on trawling came into force on December 31st, 2012. All electricity transmitting devices used for fishing are also prohibited. Under the Fisheries Protection Ordinance, any person who contravenes the ban is liable to a maximum penalty of a fine of $200,000 and imprisonment for six months.

Trawling is a non-selective fishing method which severely damages the seabed, especially trawling with electricity which kills all marine life around the trawl net and causes serious damage to the marine ecosystem.

Four new Reef Fish Species for Hong Kong

A study by Allen W.L. Lo and Stanley K.H. Shea published recently in Msrine Biodiversity Records, has found 4 species of reef fish not previously known from Hong Kong waters. They also conclude that these 4 species are not introduced. So here is a welcome list of Hong Kong’s newest residents:

Ambyleleottis japonica

A Goby that grows to only 8.5 cm length and lives near the bottom and about which very little is known.
