Misteri Fenomena Air Laut Merah Di Sabah

By Mizz Coki - Mac 27, 2012

Misteri Fenomena Air Laut Merah Di Sabah ! Sebenarnya tak la misteri mana pun. Ianya adalah fenomena biasa yang selalu berlaku di persisiran pantai, muara sungai dan laut. Fenomena ini berlaku apabila kepekatan besar mikroorganisma akuatik meningkat secara mendadak dan dikenali sebagai algal bloom. 

Oleh it, untuk mengelakkan keadaan panik dikalangan penduduk tempatan, Jabatan Perikanan Sabah telah memaklumkan bahawa kejadian Air Laut Merah atau lebih dikenali sebagai Red Tied, akan melanda di sekitar kawasan Perairan Pantai Kota Kinabalu Sabah. Antara kawasan² yang terlibat, antaranya, di Perairan Laut Pulau Gaya, Teluk Sepanggar, Persisiran Pantai Likas, Yayasan Sabah dan beberapa lokasi berhampiran. 



Sehubungan itu, Jabatan Perikanan Sabah menasihatkan kepada semua penduduk sekitar supaya tidak memakan makanan laut seperti jenis kerang dan ikan-ikan, kerana dikhuatiri dicemari alga merbahaya. Walaubagaimanapun, makanan laut dari seperti ketam, udang dan sotong adalah selamat dimakan dengan syarat insang dan organ dalaman, perlu dibuang terlebih dahulu dan dicuci sehingga bersih sebelum dimasak. 

 Kesan selepas memakan kerang beracun dalam kuantiti yang banyak, akan menyebabkan mangsa berasa mual dan boleh membawa kelumpuhan pada otot dada dan perut. Sekiranya dibiarkan tanpa rawatan dalam tempoh dua jam, mangsa mungkin akan menemui ajal.

Red tide is a common name for a phenomenon also known as an algal bloom (large concentrations of aquatic microorganisms), an event in which estuarine, marine, or fresh water algae accumulate rapidly in the water column and results in discoloration of the surface water. It is usually found in coastal areas.[1]
These algae, known as phytoplankton, are single-celled protists, plant-like organisms that can form dense, visible patches near the water’s surface. Certain species of phytoplanktondinoflagellates, contain photosynthetic pigments that vary in color from green to brown to red.
When the algae are present in high concentrations, the water appears to be discolored or murky, varying in color from purple to almost pink, normally being red or green. Not all algal blooms are dense enough to cause water discoloration, and not all discolored waters associated with algal blooms are red. Additionally, red tides are not typically associated with tidal movement of water, hence the preference among scientists to use the term algal bloom.
Some red tides are associated with the production of natural toxins, depletion of dissolved oxygen or other harmful effects, and are generally described as harmful algal blooms. The most conspicuous effects of these kind of red tides are the associated wildlife mortalities of marine and coastal species of fish, birds, marine mammals, and other organisms. In the case of Florida red tides, these mortalities are caused by exposure to a potent neurotoxin called brevetoxin which is produced naturally by the marine algae Karenia brevis. -wikipedia
