*******************************
The Agriculture, Fisheries and Conservation Department (AFCD) today (January 6) reminded mariculturists to keep a close watch on their fish culture zones and report any fish kills or irregularities in view of the recent red tide sightings that might be harmful to fish in the waters of Tolo Harbour and Long Harbour.
An AFCD spokesman said that the red tides sighted at various locations at Tolo Harbour and Long Harbour since last week still persist.
The red tides were formed mainly by Karenia mikimotoi. Overseas studies show that the species, which seldom forms red tide in Hong Kong waters, might cause adverse effects to fish.
Reports of fish loss have been received from mariculturists at Lo Fu Wat and Sham Wan fish culture zones, where the red tides have been detected since last week. The fish loss was probably associated with the occurrence of this species of algae.
The AFCD has stepped up monitoring at the 26 fish culture zones throughout Hong Kong with a view to providing early warning to lessen the impact on the mariculture industry and the public.
The spokesman reminded mariculturists to properly dispose of dead fish. Mariculturists in fish culture zones at Mirs Bay and not yet affected by the red tides may consider early harvesting their stock to minimise the associated risks.
The Red Tide Expert Advisory Group, comprising local scholars and scientists with expertise in red tides, was updated and consulted on the situation. The Mainland authorities were also notified of the occurrence of the red tides in Hong Kong.
