Yesterday by a chance look of a balcony I spotted a sea turtle swimming around the shallow edges of the inside Discovery Bay Marina. About 40 cm long it was circling around the 3 construction barges and 3 jack-up drill platforms. Discovery Bay Marina is empty of boats and floating pontoon walkways as it being renovated. I was able to observe and take some smartphone photos for about 30 min before darkness set in.
As recommended by the AFCD I immediately tried to report my sighting by calling the government hotline 1823.
Sightings of endangered animals are rare. Let’s hope it was healthy and made it out of the marina again before the tugboats arrived this morning and work started again.
The marine environment of Hong Kong comprises of a vast diversity of marine lives. In order to enrich public’s understanding on the rich marine biodiversity in Hong Kong as well as to promote the message of marine conservation in the society, the Agriculture, Fisheries and Conservation Department organises the Hong Kong Marine Biodiversity Roving Exhibition at five venues between June and December 2018. Through interactive panels and games, display of marine lives models and photo and video galleries etc, this roving exhibition aims to introduce to the public the unique marine environment of Hong Kong, fun facts of some interesting marine species as well as various conservation measures implemented by Agriculture, Fisheries and Conservation Department.
Hong Kong Post unveiled a series of new postal stamps this week, including a set featuring Hong Kong’s rich marine biodiversity designed by Shirman Lai . Revealing our beautiful underwater world, this six-piece issue aims to promote awareness for marine conservation in the hope of making joint efforts to preserve our precious marine life. For extra fun, the souvenir sheet features fish-shape perforations to match the overall fish silhouette. Among others the stamp features the Chinese White dolphin, stingrays, corals green sea turtles and jellyfish.
Three men who used trawling gear to fish illegally on August 27 were convicted and sentenced to four weeks’ imprisonment suspended for one year at Kwun Tong Magistrates’ Courts on August 29.
The Marine Police found a trawler suspected to be trawling in the waters off Conic Island (Sai Kung Area) at about 7pm on August 27 and intercepted the vessel for an inspection. Two hundred catties of fish and some trawling apparatus were seized on board the vessel.
The AFCD took over the case. Upon investigation, three men on the vessel were charged for contravening the Fisheries Protection Regulations by using prohibited fishing gear. They appeared at Kwun Tong Magistrates’ Courts and were convicted and sentenced today. The fishing gear concerned was also forfeited.
An AFCD spokesman reminded the public that the ban on trawling came into force on December 31, 2012. 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 upon conviction.
Trawling is a non-selective fishing operation which damages the seabed and marine ecosystems. A ban on trawling has brought this harmful depletion to an immediate halt, enabling marine ecosystems to be gradually rehabilitated to a sustainable level and be better conserved in the long run.
The spokesman said, “The AFCD and the Police will continue to carry out joint enforcement operations to crack down on illegal fishing activities.”
Introducing Hoilungia hongkongensis a Placozoan. What’s a placozoan? Literally it means “flat animal” and these animals represent one of the simplest multicellular life forms known. And up until this year the entire phylum (major branch of the tree of life) of Placozoans had only 1 species: Trichoplax adharens! That would be like saying that the sum of all known vertebrates was just one species.
But a team of scientists have now added Hoilungia hongkongensis making it 2!
Hoilungia – meaning sea dragon – was isolated from HK and therefore honoured with the species name hongkongensis. Don’t rush to go looking for this 1 mm across flattish blob though. Placozoans are utterly featureless and have only 5-6 different cell types – one of which is the epithelial cell which has little beating hairs that propel the animal across the sediment (slooowly) where it feeds like an amoeba by engulfing detritus. Like other featureless or cryptic species this one was identified and separated from others by genetic analysis alone. Basically there is nothing to look at.
