How a Handful of Fishers Show How Harpooning Can Be an Ecologically Sustainable

By Bharath Thampi
THIRUVANANTHAPURAM, India, Mar 20 2026 – Sudhi Kumar animatedly moves his hands, resembling a graceful dance performance, as he demonstrates how a fishing harpoon is used. He has been on a brief hiatus from harpooning, owing to the recent rough nature of the sea, and doesn’t have the tool with him as we speak. But more than three decades of experience using harpoons is apparent in how vividly he uses his body to mimic the process.

Sudhi, 51, is a fisher belonging to the globally sought-after tourist beach village, Kovalam, in Thiruvananthapuram – the southernmost district of Kerala, India. Sudhi has a unique distinction among the fishing communities of Thiruvananthapuram, which has a significant coastal population. He was the first one among the natives to learn and employ the method of ‘harpoon fishing’. Moreover, Sudhi belongs to a minuscule section of fishers in the whole of Kerala itself, who practise this uncommon, albeit highly sustainable and ecologically friendly, method of fishing.

“Harpooning and spear fishing may look very similar to an outsider but are vastly different,” Sudhi says. “Our ancestors have been known to have used spears built of tough wood or other materials. But a harpoon was a totally foreign object to the fishers here.”

Kovalam was a thriving beach tourism spot by the 1990s. Sudhi, barely out of his teens but an expert swimmer and diver by then, used to accompany his father for fishing, as well as act as a snorkelling guide for foreign tourists.

“One time, a Frenchman came to me with a harpoon, and he told me he needed my help in fishing with it in the sea. I was seeing the equipment for the first time in my life,” Sudhi recollects the event from nearly 35 years ago.

After the man was done fishing, Sudhi requested him to let him try the harpoon once. The foreigner was quite impressed by Sudhi’s deep-sea skills and handling of the harpoon despite being a debutant. Sudhi even caught a large Vela Paara (Silver Mooney fish) that day.

“Before he left Kovalam, he handed me the harpoon as a gift, to my pleasant surprise. I was so thrilled – I was the only one here who owned it,” says Sudhi.

He started harpooning quite frequently since then, an amusing sight for the other fishers in Kovalam. “I also realised that I could earn a lot more through harpooning than accompanying my father in his boat.”

But Sudhi was also aware that a harpoon was still a rare commodity to procure, not just in Kerala, but across the country, at the time. For one, it was costly, and most fishers couldn’t afford it. He held himself back from using it on significantly large fish because he was afraid of damaging or losing the harpoon.

Dr Shobha Joe Kizhakudan, head of the Finfish Fisheries Division at ICAR-CMFRI (Central Marine Fisheries Research Institute), agrees that harpooning is considered one of the most sustainable fishing methods by scientific experts as well. But there had been a bit of stigma attached to it in earlier years, she says, because of how “cruel” the method of killing could be.

“For example, harpooning was once a main technique used to catch whale sharks and other shark species, before the ban came into effect. Once harpooned, the fish would be dragged alive, fighting for its life, until the shore,” Kizhakudan says.

Sustainable Development Goal 14 (SDG 14: Life Below Water) aims to conserve oceans and sustainably use marine resources, with a core target of ending overfishing and illegal and destructive fishing practices by 2020. The way Sudhi uses it could fit with this definition.

However, Sudhi also acknowledges that he avoids shooting larger fish, which may survive a single harpoon shot, because it’s a merciless and amoral act. But he hadn’t always been so conscientious, he reminisces.

“Many years ago, as a young man, I once accompanied a tourist called Paul to the sea, who was capturing on video underwater marine habitat as well as my harpooning. Paul had been fixated on a pair of Bluefin Trevally, which clearly seemed to be doing a mating ritual. After waiting for a while, I grew impatient and killed one with a harpoon shot. Paul looked back at me with a heartbroken expression and nodded his head sadly. I felt awfully guilty. That feeling has stayed with me since.”

Harpooning is no easy feat, Sudhi points out, a key reason why there are very few practising it. For one, it’s a waiting game: you need to hold your breath and stay underwater for minutes at a time before a fish comes close enough, and you have the measure of its movements to harpoon it.

Friends of Marine Life (FML), a coastal indigenous civil society organisation based in Thiruvananthapuram, has been video-documenting the marine biodiversity of the region, especially the natural reef ecosystems, for quite some time now. Robert Panippilla, the founder of FML and a certified scuba diver, had extensively documented the harpooning method with Sudhi.

“Harpooning can only be practised in regions with rocky habitats. Hence, Kovalam is an ideal location for that,” Panippilla says. Having covered diverse fishing practices as part of his documentation, he says that harpooning is one of the most unique and toughest skills.

“Not only do they have remarkable underwater stamina and manoeuvrability, but it’s also imperative that they possess adequate geomorphological understanding of the sea and the behaviour of the fish. Just because someone comes to possess a harpoon, they may not be able to use it effectively.”

To Robert’s knowledge, barring the harpooners in Kovalam and a scattered few in Vizhinjam, there’s nowhere else in Kerala that harpooning is practised. He considers harpooning a great sustainable fishing method because it’s very selective in practice. “There’s no risk of overfishing, juvenile fish being caught alongside others, or the ecological issue of ghost nets being abandoned at the bottom of the ocean, like in net-fishing.”

Unlike the early years, when Sudhi was the only one who sported a harpoon, others have now gotten into the trade in the region. Most of them got the harpoons from abroad, particularly through those returning from the Middle East. Many of them were trained by Sudhi himself before they started doing it independently. At present, in and around Kovalam, there must be around 25 fishers engaged in harpoon fishing, he reckons. As far as Sudhi knows, harpooning is a rarity across India itself, most likely practised in islands.

The Southwest monsoon phase in Kerala, especially in the month of August, is the best time for harpoon fishing, in Sudhi’s experience. Groupers (fish) are aplenty on the Thiruvananthapuram coast, and some seasons have earned him catches worth lakhs of rupees. Rays and Barracudas are a couple of other common harpooning targets for him. Besides harpoon fishing, Sudhi frequently goes diving for mussels and cage fishing for lobsters.
