Technology for raising fish in the desert reaches high productivity of Israel

More than half of Israel is desert, unfavorable climate, lack of water, but Jewish people have made the world admire the technology of raising fish in the desert. Not only can they supply enough fish for domestic demand but also export to other countries around the world.

Fish farming technology in the desert makes the world admire Israel

Agriculture is a highly developed industry in Israel : The country is an exporter of important fresh produce, the world's leading country in agricultural technology, although natural conditions are not conducive to agricultural production. however, the country always knows how to apply high technology to improve agricultural product quality.

Farming fish in the desert

Israel is also known as the 'Silicon Valley ' of the world in the field of agriculture and water technology. Only 1.7% of the population works in agriculture, but every year Israel exports more than US $ 3.5 billion of agricultural products, making it the world's leading agricultural exporter.

According to Mr. Dotan Bar-Noy - GFA Company CEO, over the past few years, widespread fishing has greatly influenced the marine resources. Without proper moves to prevent, many saltwater fish will disappear completely.

ISrael always knows how to apply high technology to increase agricultural productivity, especially fish farming technology in the desert.

Mr. Dotan Bar-Noy along with more than 30 other people, mostly engineers, marine biologists combined with folk techniques have found a new solution that contributes to reducing indiscriminate fishing that makes the species and the number of marine fish is declining today, it is the new technology that can allow marine fish farming in the mainland, especially in the desert . This is a system that uses special biofilters and bacteria to treat wastewater produced during fish farming, so it does not affect the environment.

After the independence day, geological surveys and water sources were carried out in desert and semi-desert areas such as the Negev. The Israelis have sought to find ways to extract saltwater from the ground and build water recycling systems to combine aquaculture and cultivation, maximizing the efficiency of water use, renovation and fallowing of abandoned land. .

Israeli fish farming systems will reuse 99% of water and filter fish waste as fertilizer for crops. Fishpond waste water will undergo a complex recycling system to clean up toxins and sludge, and then be reused for aquariums.

This Jewish system can be used anywhere on the mainland as long as there is a certain starting source .

Fishpond waste can be a nutrient for plants, but this closed system still needs to be cleaned about once a year due to sludge clinging to sieves and mechanical systems.

One factor that fish farmers are very worried about is the disease problem. However, on these closed fish farms, the source of infection usually comes from new fish stocks when taken to the farm, and the natural and wild fish will be very low.

Drip water

One of the key successes of the fish farming industry in Israel is the technology to identify groundwater as well as optimize the efficiency of water use to drop , thereby allowing people to raise fish on. desert with limited water.

Besides, due to limited water, Israelis often accumulate water in the winter to use for agriculture in the summer. Taking advantage of this, fish farms have used stored water to use aquaculture, providing additional food while ensuring the amount of water supplied to agriculture in the summer.

With regard to environmental and ecological pollution, Israel applies an extremely strict water treatment system, while raising awareness about water saving as well as environmental protection for people.

The Israeli government also has special support for investment in agriculture or aquaculture. Up to 24% of the total amount of government support is for agriculture and aquaculture projects and businesses in this sector are exempt from all import taxes.

Today, thanks to those early efforts, 'more than 10 ultra-large fish farms were built in many areas of the Negev, ' wrote Shmuel Rothbard. Water from the ground is fed into fish farming and then used for irrigation for crops.

Fish ponds are now available throughout Israel, many new fish species are introduced. Israelis feed carp, tilapia, grass carp, flatfish (mullet), bass, bream, salmon and some ornamental fish.

However, it is not difficult for Israeli fish industry.'Many farms in Lake Galilee are abandoned when water prices rise, ' said Israeli Fisheries Association secretary Yossi Yaish. ' The Galilee region has potable water and cannot use that precious water to fish'.

The key to the success of the Israeli aquaculture industry lies in knowing where there is abundant water, how to maximize the benefits of each drop . The country's most important technological progress in aquaculture is to realize the will to raise fish with a rare strategic reserve water in the smartest way.

Moreover, attention to quality of fish has helped Israel improve its native freshwater fish. Currently, the fish industry in Israel produces 20,000 tons of fish each year. With the current price of about 3.5USD / kg, the fish farming industry has a turnover of 70 million USD / year. Fish farmers in this country hope to dominate the European market soon, diversify products, and even develop seafood tourism.
