Jellyfish has always been considered an inedible and therefore useless catch by the fishing communities in the country’s coastal districts. Despite never being considered as commercially viable, new research by Bangladeshi scientists indicates jellyfish can eventually become a source of export earnings. Like elsewhere, the coast of Bangladesh too plays host to a large number of jellyfish. However, the researchers do not yet know how many jellyfish there are in the waters of Bangladesh. This amount will have to be verified in the research they have now started. Made up of 90 percent water, jellyfish have no brain, blood, or bones. Scientists say that the number of jellyfish depends largely on the salinity and temperature of the water. Due to the lack of rain this year, the salinity of the seawater was high, resulting in an abundance of jellyfish washing up on shore.

Rashed-Un-Nabi, Professor, Department of Fisheries, Chittagong University told UNB, "Many countries in the world are researching how to use jellyfish, we have also started research. It shows that it has a lot of economic potential.” Scientists saw a boom or excess of jellyfish on Patuakhali beach and Cox's Bazar beach in August. At that time, many fishermen were forced to cut their nets because they were filled with jellyfish. Golam Mostafa, associate professor of Noakhali Science and Technology University (NSTU) said, “We can divide the jellyfish found in the sea of Bangladesh into three categories.” “One is edible jellyfish. We don't eat it here. But it is in demand as food in Taiwan, Vietnam, Thailand, and China. Each of these jellyfish can weigh up to 8 to 10 kg,” he said.

This type of jellyfish can also be used as raw material for the pharmaceutical and cosmetics industry. There is another type of jellyfish, which is poisonous. Physical contact with this type can damage a person’s nervous system and lead to paralysis. However it is only a very specific subtype of jellyfish that tends to be poisonous. The Box Jellyfish, so-called for its box-like physique, is classified as one of the most venomous creatures on Earth, containing toxins that attack the heart, nervous system, and skin cells. Golam Mostafa observes that fishermen need to be made aware of and trained on this type of jellyfish.

The third and final type of jellyfish found in Bangladesh is a very small creature. These are used in aquariums or as part of beautification in many countries, he said. “You can call it recreational use. Many countries, including Thailand, have such aquariums, where palm-shaped transparent jellyfish are kept. The colour of the light you cast becomes that colour. It is a very attractive thing for tourists,'' Golam Mostafa said, an associate professor of NSTU. He said that the researchers of oceanography and fisheries departments of some universities and the Bangladesh Oceanographic Research Institute (BORI) are researching the potential of jellyfish.

Around fifty carcasses of jellyfish washed ashore along different points of Cox’s Bazar beach on Sunday morning. These dead jellyfish have been washed ashore by the tidal water throughout Sunday from Labani point to Sugandha point of the beach. Around 50 small and large jellyfish carcasses were found stuck in the sand at various points of the beach. But no one could tell the reasons behind this huge number of dead jellyfish turning up Abdur Sukkur, a fisherman in the Himchari area, said that it's very unusual for so many jellyfish to die at a time. Read: 38 held for illegal fishing in Sundarbans Deepak Sharma Dipu, president of Cox's Bazar Forest and Environment Conservation Council, said it is important to investigate the reason behind the sudden death of so many jellyfishes. These jellyfish might have come close to the shore and got caught in the fishermen's nets. Later, the carcasses started washing up on the beach as the fishers threw those away, said Abu Syed Muhammad Sharif, head of the Biological Oceanographic Division of the Council. He said that if people come in contact with dead jellyfish lying on the beach, it can cause various problems, including itching. Jellyfish can still emit toxins when dead or broken apart. General Secretary of Cox's Bazar Fishing Boat Owners Association Delwar Hossain said that there was no report of jellyfish being caught in any trawler's net. Although rare, this is the second such occurrence in the space of a month. Earlier on August 4, it was reported in the media that almost 100 such jellyfish carcasses had washed up on Cox's Bazar beach in one day.
