Shibu Dasan has been artisanal fishing for the last 40 years. His familiar works of art at sea are various forms of hook and line fishing, especially natural reef areas deep sea. He has also experiences in different types of gill/driftnet fishing; echavala, valuvala. His fishing expeditions are not limited to the Kerala coast, he used to venture various types of net fishing activities in other states including Karnataka (Malappa) and Muttom in Tamil Nadu in his early period of fishing expeditions. Last year (2023), he conducted fishing expeditions based in Quilon for a couple of months. His fishing activities have been extended to Kayamkulam (Alappey district). During his early years of fishing expeditions, he has learned the indigenous technology of Kanicham (equivalent to modern GPS), from his elders, especially Mathias, the skillful fisherman from Marianad. Since the introduction of modern GPS, he has lost touch with the indigenous technology of Kanicham. For the period of five years (2007-2012), he was in Gulf Countries, in particular Abudabi for fishing related occupational activities. He did mainly hook and line fishing activities there in collaboration with other traditional fishers from Tamil Nadu and Gujarath. Since he returned from the Gulf countries, he continued to work with his fellow fishers in Marianad, engaging in hook and line fishing. But during the coroana pandemic, he had to shift his fishing technique to net fishing (rolu vala) again and during southwest monsoon period, he does boat seine fishing. He has some understanding of weather conditions at sea based on his Indigenous Ecological Knowledge. He noted there has been a change in ocean climate for the last some years.
