The Ecologically Destructive Technique of Blast Fishing and Cyanide Fishing

Leave a comment

Blast fishing was introduced in Southeast Asia post World War II, by American soldiers who threw grenades into bodies of water to yield a large cache of fish, a technique which is used  during the modern day to produce fish as a food resource in local markets. Dynamite is often used but any explosive will perform the task effectively, even improvised devices which utilize an explosive chemical within a glass drinking bottle with an improvised wick lit by a cigarette. Cyanide fishing is an ecologically destructive method of catching fish in which a diver takes bottled cyanide and pumps it into reef areas where fish reside, stunning the fish and making them easier to catch, so that they can be extracted for the pet and live fish trades. These techniques result in coral reefs losing their color and ultimately dying, eliminating a major food source for marine life within the region. Both methods are extremely damaging to the ecosystem and left unchecked, can decimate entire ecosystems within a few short years. Portions of and entire coral reefs which have slowly built over thousands of years can be destroyed in a matter of seconds by using either of these harmful techniques. Fortunately, both methods of fishing are illegal in most of Southeast Asia

The Discovery of the Sunken S.S. Titanic

Leave a comment

The S.S. Titanic’s shipwreck site was found by the U.S. Navy whilst embarking upon a clandestine military submarine sea voyage operation in 1982. The intent of the mission was to surpass the Russians on every front, including land, sea, air, and space. Geologist and Navy Captain Robert Ballard was the person who developed the mission idea by suggesting that the U.S. Navy scour the seafloor to gather intelligence and search for evidence of Soviet placed hardware. The original intention of the mission was to locate and recover 2 U.S. Navy submarines which were classified as top secret nuclear attack vessels and lost during the 1960’s. The first submarine was the U.S.S. Scorpion, lost in 1968 with 99 onboard, and the second was the U.S.S. Thresher, lost in 1963 with 129 onboard. Recovery of these vessels during the 1960’s was limited to the Sound Navigation and Ranging technology of the era, commonly abbreviated as “SONAR”. Ballard only had 12 days to locate the S.S. Titanic during the mission without exposing his cover story, a feat which was unable to be completed by the French and the Americans, despite having much longer time spans and multiple expeditions to achieve this goal. Ballard narrowed down the search area to 80 square kilometers and focused towards the south as he believed that ocean currents would have carried sunken debris in that direction. Ballard continued searching for a trail of scattered debris from the S.S. Titanic and on the 9th day of the expedition, with time quickly running out, the operators of the remotely operated vehicle ARGO, found wreckage from a modern iron ship which appeared to be from the early 20th century. It was confirmed shortly after on September 1, 1985 at 12:48 AM that these remains were 1 of the 29 boilers belonging to the S.S. Titanic. It had been 73 years since the S.S. Titanic was last seen, resting nearly 4 kilometers below sea level, with it’s 1500 onboard passengers and crew

The Annual Hindu Rain Festival of Ambubachi Mela

1 Comment

For 3 days each June, typically always starting upon June 22 and ending upon June 26, but fluctuating due to various influences, the Hindu festival of Ambubachi Mela is observed. Sadhu’s, that is, holy men of the Hindu faith, and pilgrims from all over India gather at the Kamakhya Temple (pronounced “kah-mah-kee-yah”) in Guwahati, India, a site located upon a hill near the Brahmaputra River, to pray for rain. It is believed by Hindus that the presiding goddess of the temple, Devi Kamakhya, who is the Mother Shakti, goes through her annual cycle of menstruation during this festival. The Kamakhya Temple becomes closed for 3 days during the mela as it is believed by Hindus that the Earth, commonly associated as Mother Earth, becomes unclean for 3 days and therefore should be secluded in the same format that some traditionally practicing Hindu women seclude themselves during their own menstrual cycles. During these 3 days, some restrictions are observed by the Hindu devotees (e.g. cessation of cooking, cessation of performing worship which is referred to as “puja”, cessation of reading holy books, cessation of farming etc.). After 3 days, Devi Kamakhya is bathed by cleaning the statue which represents her with red pigment flowing from her vaginal canal, alongside other rituals which are carried out to ensure that the devi retrieves purity. The doors of the Kamakhya Temple are reopened on the 4th day and devotees are permitted to enter Kamakhya Temple to worship Devi Kamakhya. The devotion of these pilgrims is believed to bring rain and fertility back to the Earth

The Etymology of Guatemala and Traditional Guatemalan Fishing Techniques

Leave a comment

Guatemala

The term “Guatemala” comes from the Nahuatl term “Cuauhtēmallān” which means “place of many trees”, a derivative of the K’iche’ Mayan language term for “many trees”. In Guatemala, those who fish commonly do so by using a technique not seen in many other places. People who fish slap the water with the horizontal edge of their machete to stun fish who are swimming nearby. Once stunned, the fish is caught and brought out of the water so that it can be cleaned and consumed

The Connection Between Parrot Fish and Sand

On some beach islands in the Maldives, as much as 70% of all sand comes from the excrement of parrot fish. Parrot fish primarily consume coral which is composed of calcium carbonate and causes their excrement to become white sand. A single parrot fish can eat enough coral to expel 1 tonne of sand within a single year
