How Nutrient From The Sea Ended Up In The Forest?

It’s hard to believe that trees deep in the forest get their nutrients far-far away from the sea. That what the wonder on nature when they work together accordingly. One of examples that we can see is the returning of salmon during the breeding season.

Salmon is one of few species of animals that start their life in the freshwater and spend their growing time in the sea then return back only to lay their eggs. As they return their journey back to the deep forest that might take few thousand kilometres as example of chum salmon (Oncorhynchus keta) that travel the longest journey far up to Yukon River and deep into the Amur River basin where the journey will take more than 3,200 km (2,000 mi).

Within their journey they will become meals for numbers of other animal species such as eagle, otter, water birds, and bear that waiting for their returning from the sea. Then for the surviving salmon will continue their journey to their breeding place far into the forest. Their journey up the river requires them to have strong muscles, with it they are capable to leaps more than 2 meters height.

Travelling far from the sea will make salmon lost lots of energy all of them will die after spawning their eggs. Their carcases might be taken by other animals out of the water and left the remaining alone. Then the remaining will become home to blow fly’s larvae that will eat on the remaining flesh.

Once they are ready, the maggots will buried themselves in the soil until they emerge as adult flies. These flies again will do another important thing for plants and trees in the surrounding areas; pollinating the flowers to make sure they can produce seeds for their next generation.

We might think that salmon just one species of animal and maybe important to those few animals that eat them. With closer observation we can see how all the ecosystem intertwine together with every single piece of them nourishing one another.

Even though each female salmon can carry from 2,500 to 7,500 eggs depending on size and species, only some of them will hatched. From that numbers less than 2 percent will return to the same location to spawn again in the next 6 to 7 years.

More Interesting Things About Flying Fish

Flying fish is the only fish that can fly or actually gliding in the air in order to avoid their predators. Compared to its body size the distance they can achieve from the glide is considered very far. Even though this behaviour help them to run away from the predators, but their predators too have different techniques to catch this super leapers.

Flying fish are family of fish known as Exocoetidae, in the order of Beloniformes class Actinopterygii, with 64 species from 9 genera. They can be found in all of the oceans, mostly in tropical and warm subtropical waters. That’s the other reasons why flying fish is quite popular as part of people’s culture all over the world, from Japan, Vietnam, China, Indonesia, India, South America such as Barbados and Trinidad and Tobago. Besides of that, flying fish still can be found in many other areas (even when they are not become part of people consumptions for that areas).

Flying fish can achieve great distance when they gliding above the sea. The distance can get farther with the right condition of wave and wind. They can reach up to 4 feet heights and gliding distances up to 655 feet. Sometimes they will continue the jump soon after touching the water to reach longer distances up to 1,312 feet. They also can soar high enough and sometimes get stranded on the decks of ships.

Flying fish become important food source for other bigger species of fish in the sea and when they leap out the water, birds too will take advantage to make them as their food. With their size can reach up to 18 in (45 cm), flying fish is consider moderate in size. Flying fish had been using in many dishes all around the world. One of the popular dishes is the flying fish sashimi from Japan.

Fisherman caught them with different ways such as using gillnetting in Japan, Vietnam and China, while using dipnetting in Indonesia and India. There’s also a technique using lights to catch this fish as they are attracted to the lights (especially during the dark moon).

Even though flying fish is not considered as threaten species, their hunting should be controlled in order to avoid overfishing. Flying fish is important to human especially in some cultures, but they are more important to the nature itself.

Snail Farming and What It’s All About?

Never thought that snail farming to be one of the most profitable farming industries today. Even though it’s not as popular as many other farming industries, snail farming gain popularity when their usage get more than just for human consumption. While only few countries in the world popular with snail’s dishes but beauty industries spread to wider user and the substances for their products produces by this wonderful creature; snail.

Snail farming is not new to human. The farming practice had been described long ago in Lumaca romana, (translation: Roman snail) by Fulvius Lippinus (49 BC). We don’t know how long it’s been practiced before the documentation. It also indicate snail was one of the important resources since long-long ago.

Snail farming known as heliciculture, or heliculture is the process of raising land snails for human use either as food source or other usage such as producing slime for cosmetics industries or snail eggs as a type of caviar. There are many land snails use as food all around the world, but the popular snails known as escargot mostly refers to either Helix aspersa or Helix pomatia, and they both are tasty.

While for cosmetic purposes, snails slime been used since ancient Greek to improve face moisture, to reduce wrinkles and to rejuvenate the skin (that includes reducing scars or blemishes). Snail’s slime or mucin contain hyaluronic acid, glycoprotein enzymes and peptides – that used in many other products not produced by the snail mucin.

If you’re interested to try the snail mucin products, it’s better you to try the ready cosmetics – for the mucus/mucin already treated clinically for safety usage (so use the known brands for extra safety). Snails as any other animals can be infested by many diseases, pest, worms and many other kind of infection. Proper preparation is very important to make sure your safety for using such kind of products.

Back to the snail’s farming, it can generate large margin of income – for the cost of running snail’s farm is lower. Instead snail’s farm getting popular not only in European countries but it also grows rapidly in Africa, North and South America and Australia. In fact there are many other species of snails being farmed. Some of the species included;

  • Helix aspersa, also known as "petit gris," "small grey snail," the "escargot chagrine," or "la zigrinata".
  • Helix pomatia, also known as "Roman snail," "apple snail," "lunar," "la vignaiola," the German "Weinbergschnecke," the French "escargot de Bourgogne" or "Burgundy snail," or "gros blanc".
  • Otala lacteal, also known as "vineyard snail," "milk snail," or "Spanish snail".
  • Iberus alonensis, the Spanish "vaqueta" or "serrana".
  • Cepaea nemoralis, "grove snail," or the Spanish "vaqueta" from central and Europe and introduced to United States.
  • Cepaea hortensis, "white-lipped snail" native to central and northern Europe.
  • Otala punctate, "vaqueta" found in some part of Spain.
  • Eobania vermiculata, "vinyala," "mongeta," or "xona", from the Mediterranean countries, then introduced into Louisiana and Texas.
  • Helix lucorum, "escargo turc" quite big with size up to 45 mm across from central Italy and Yugoslavia, Crimea to Turkey and around Black Sea.
  • Helix adanensis, from Turkey.
  • Helix aperta, native to France, Italy and other Mediterranean countries. Nowadays already established in California and Louisiana.
  • Theba pisana, "banded snail" or the "cargol avellanenc", native to Sicily and spread to several European countries, including England.
  • Sphincterochila candidissima, also known as "cargol mongeta," or "cargol jueu"
  • Achatina fulica, or giant African Snails can reach size up to 326 mm (1 ft ¾ in) in length. Native to south of the Sahara in East Africa. Also caused serious agricultural pest problem in other areas such as California, Hawaii and North Miami Florida. Still giant African Snails is the most popular snail as pet.

All of the snails above are example of land snails that grown in snails farming. Without proper care snails can be serious agricultural pest problem especially when it come from other areas. Some snail species can increase in numbers very rapidly when the condition is right such as giant African snail that threaten not only native snails but also others animals that feed on the same food sources.

As the snails farming is still considered new. Many other possibilities can be achieved with more research and development to identify the potential of snail’s base products. While at the same time, farmers need to be responsible to make sure the safety of the farming method to avoid the harmful effect of snails to natural/local environment.

Fish Farming Of The Future

Fish is one of the important protein sources but badly affected by many issues from pollution, over-fishing, unsafe even for farmed fish and caused threats to environment. While stopping fish farming will never stop the other threats for the wild fish and we still need fish as part of our foods. Luckily some of us never stop to find better ways to raise farm fish with better condition.

Farming fish is not an easy job especially salmon that requires both between salt water and fresh water. This fish is bigger in size with carnivorous appetite. Farming salmon in the net-pens over the rivers and lakes been practiced for so long and proven caused many problems for the fish itself and for the environment. Using other fishes as their food also another reason salmon farming will not solve the over-fishing problem.

With more people come forward and pressure from the consumers, fish farmers find another solution – to raise salmon in land away from natural water supply. With enclosed environment all factors are control properly from the quality of water, oxygen content in the water, salinity to food supplies. These lead to easier manage conditions; even though the cost of building the facilities far higher than traditional net-pens farming.

One of the pioneering company in this technology is KUTERRA that raising Atlantic salmon (Salmo salaron their farm at Northern Vancouver Island, Canada.

The land farming allows farmers to control many other threats to their fish such as predators, pollution from the water, diseases and water from the farm also never goes into the river/sea. With high circulation of water, low fish feed, controlled temperature and oxygen, the growth of fish are much faster with no diseases. In case of diseases they can change all the water and sanitized all the facilities again.

More and more land farm will be build. Photo by: undercurrentnews.com

Even though the cost to build land farm are far higher, but it can produce higher yield with good quality of fish. Not to mention they never caused any harm to nature (other than the land they need to use to build the farm). This technology is still in its early stage and there are more improvement in the process and management that will bring better result.

In fact salmon farming is not the only technology that got a facelift in recent years. All other fishes with high demands and threaten in the wild such as tuna, grouper, cobia, puffer fish, and few other shellfish/crustaceans also had been upgraded. This upgrade not only to produce more production but also to make sure that the produce will be safe for human consumption with less impact to the environment.

Deep sea farming also will be part of future fish farming. Photo by: innovasea.com 
With more people work together to improve the quality of fish farming industries, it will benefits both the consumers and the farmers. While at the same time we hope that will allow the restoring amount of the fish in the wild from over fishing – but still threatens by pollutions of many kinds.

New Fabric From Orange Fibre

Producing orange fibre to safe cost of disposal orange's waste. photo by: orangefiber.it

Most of modern fabrics are produce by synthetic materials and rarely new materials came from organic materials (as we already stick with few of the traditional materials as we known such as cotton, silk, linen, wool, jute, pineapple leaves, lotus silk and etc.). It shows that many other organic materials consist potential fibre to be use in producing fabric – perhaps need to go through different process.

At least that’s what student Adriana Santanocito and her friend Enrica Arena tried to do and successfully produced what they called Orange Fibre. Adriana was studying textiles at Politecnico of Milan, when she first thought about to produce the fabric from orange fibre. This idea came when she thought about how scientist can produced fabric out of milk and rice. Then she also thought about the problem of the citrus waste back at her home Sicily.

We can produce fabric with cellulose produced by plants that generally known as rayon. The fabric that made of bamboo is actually rayon. Still there’s nothing bad about it. In fact rayon can be produced at cheaper price, safe lots of energy and farmland to grow fibre plants such as cotton, flax, hemp, jute, nettles, yucca and many others.

By producing orange fabric, Adriana helps to make sure the orange waste used for something more useful rather than to left it rotten and safe the huge amount of money with the disposal cost. Instead of using new trees to produce pulp, why not using the cellulose from other waste product such as in this case – she did a very good job.

Rayon allows fabrics price become cheaper as the plants fibre produced by few types of plants are harder to produce. It also allow wider range usage of fabrics for applications from tea bags, to fabrics for high quality dress. The only things that we concern about rayon production is the usage of harmful chemicals and their effects to the workers and environmental effects (when the waste management not been carried properly).


Orange fabric is another example of creative idea on how we can safe resources that before treat as waste. As we know that in ancient times, clothes are afforded only by the riches and they are very hard to produce. With new materials engineering will allow us to explore more possibilities to get better materials that are not just cheaper but also good for the nature.
