The Fermentation and Manufacturing Process of Ancient Roman Garum (Fish Sauce)

Leave a comment

The Ancient Roman’s created a special fermented fish sauce called “garum”. Garum was highly valuable and in modern times accounting for inflation, garum would cost $1250.00 for 1 liter. Garum was made from nothing more than salt and decayed fish. The original preparation is unknown as the ancient recipes have been lost. The fishes organs and digestive fluids help in the fermentation process. The container which the garum is made in is left in the sun for a few days to allow the process to ferment as much as possible. The oily slush oozing from the fishes organs and digestive enzymes is the garum and it is loaded with nutrients and contains glutamate which triggers chemical receptors on the tongue to make the brain crave more of it. Glutamate is the primary ingredient/component in monosodium glutamate, commonly abbreviated as “MSG”, and is used by many chefs all over the world

The First Human Beings to Migrate to North America

1 Comment

The first people to arrive in North America are suspected to have arrived 15,800 years ago. Sea levels were much lower because of polar ice caps being frozen, which allowed modern day Siberia and Alaska, United States of America, to be connected. How migration occurred is still debated, with some scholars hypothesizing that walking whilst hunting large mammals was the most likely way, while others propose that the indigenous people of North America hunted along the shoreline using maritime skill sets and travel vehicles. 10,000 years ago, the ice sheets receded northbound allowing for civilizations to domesticate northern British Columbia, Canada

The Reason Life Upon Earth Migrated From the Ocean Onto Land

Leave a comment

Billions of years ago when the first living organisms started harnessing the energy of the sun through photosynthesis, they began producing a waste product which was oxygen. When oxygen rises high up into the atmosphere, it transforms into ozone which is why the Earth has a thin protective layer of ozone which alongside the magnetic field, helps protect the Earth from the violent ultraviolet radiation spewed out by the sun. As plants, microbes, and fungi migrated from the water to land, even more oxygen was produced, extending the ozone layer to become much more formidable. This was the catalyst for life migrating onto dry land which occurred 450,000,000 – 500,000,000 (450 million – 500 million) years ago during the Paleozoic Era, specifically during the Ordovician and Silurian periods

The Country With the Most Vegetarians Per Capita and the First Notation of Vegetarianism Within Western Literature

1 Comment

The country with the most vegetarians per capita is India, with 39% of the country identifying as vegetarian and/or vegan, a value which equates to 276,000,000 (276 million) people. This is primarily due to the dominant religion within India which is Hinduism, a faith which 79.8% of the country subscribes to, and to a lesser extent, Sikhism, a faith which promotes vegetarianism and is subscribed to by 1.7% of the country. Mexico trails India for the second spot internationally with 19% of the country identifying as vegetarian and Brazil takes the third spot with 14% having adopted this diet. The first time vegetarianism is mentioned within recorded western history is by the Ancient Greek mathematician Pythagoras around 500 BC, however it is unclear if this is the first recorded text worldwide

The Reason it is Impossible to Store, Purchase, and/or Sell Live Tuna

1 Comment

It is virtually impossible to store, purchase, and/or sell tuna fish live as tuna die shortly after capture. This is due to the fact that tuna breathe using ram-gill ventilation, which means that they must constantly stay in motion to have water pass over their gills and feed their body with oxygen. Motion is required continuously, exerted during both hours spent awake and time spent asleep. As the tuna is in motion, water flows into its mouth and over its gills and gill filaments, diffusing oxygen into the tunas bloodstream while simultaneously releasing carbon dioxide. This function is performed equally well at both slow and high rates of speed as long as consistent motion is achieved

The Ecologically Destructive Technique of Blast Fishing and Cyanide Fishing

2 Comments

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 Titanic

Leave a comment

The 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

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

Leave a comment

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
