At the end of the monsoon rains every year, Mumbai's fishing community perform a traditional religious ceremony to mark their return to the sea, with offerings of coconuts and flowers, and prayers for safety and bounty.
This week, as they launched their freshly painted boats into the water, there was an added prayer: the preservation of their homes and livelihoods as a new coastal law threatens them.
Changes to India's Coastal Regulation Zone (CRZ) rules this year have lifted the ban on land reclamation for commercial purposes, will allow tourism in ecologically sensitive coastal areas and permit construction of the world's tallest statue on an artificial island near Mumbai.
The fishermen - known as kolis - say the changes will lead to environmental damage, displace coastal communities and hurt the livelihoods of millions who depend on the sea for their survival.
"The coastal lands are ours by tradition. The state plans to take them away with this law," said Rajhans Tapke, general secretary of the Koli Mahasangh association.
"Our land will be lost, our access to the sea will be affected, our catch will be affected. How will we live?" said Tapke, who lives in Versova koliwada, or fishing village, home to his family for generations.
The kolis are among the city's earliest inhabitants, with settlements dating back more than 400 years.
The name Mumbai is believed to derive from Mumba devi, patron deity of the kolis.
Yet most kolis do not have titles to their homes or the land on which they spread their nets and dry their catch.
Versova is one of nearly 40 koliwadas in Mumbai, its squat homes and colourful boats dwarfed by towering apartment blocks and malls in the city which boasts some of the priciest real estate in the world.
City officials have long clashed with the kolis' right of use of coastal land.
The kolis, whose song and dance are part of Mumbai tradition and who have featured in Bollywood movies, have lost swathes of land over the years to railway stations, schools and parks.
They have resisted attempts by city officials to classify their settlements as slums, so they can be redeveloped with some land taken for commercial developments.
"Use of coastal land has always been tenuous, with the state pushing against people who have traditional land-use rights," said Manju Menon, a senior fellow at the Centre for Policy Research, a think tank in Delhi.
"In an urban area like Mumbai, with competing interests of the tourism and real estate industries, it is particularly contentious," she told the Thomson Reuters Foundation. India's coastline is more than 7,500 km (4,660 miles) long, and about 3.5 million people make a living from fishing and related activities.
There are more than 3,000 fishing villages along the coast, from remote rural hamlets to bustling urban settlements in cities such as Mumbai and Chennai.
The set of rules regulating coastal development, known as the CRZ notification, was first issued in 1991.
The 2011 notification, which placed greater limitations on development, came about after consultations with kolis, and created coastal committees that also represented them.
Amendments to the notification this year, permitting reclamation of seabed land for coastal roads and tourism facilities, were made despite objections from fishing communities and environmentalists, analysts say. Kolis in Mumbai say they will be badly hit.
The notification also allows Maharashtra state to build a proposed 192-metre (630 ft) tall statue to commemorate Shivaji, a 17th century warrior king.
Fisherfolk say construction will disturb their catch, and pollution will increase from ferries plying to and from the statue.
Separately, a 10-km sealink that is part of a proposed coastal road to connect the city's southern tip to the suburbs will destroy mangroves and affect their catches, they say.
Fishermen are already battling industrial effluents and solid waste that drains into the sea, pollutes the mangroves and washes up on the beach.
"The CRZ was meant for our protection, but now they have diluted it so much we have lost all protection," said T. Peter, general secretary of the National Fisherworkers' Forum.
"They want to smash the fishing villages and build hotels and flats; where will we keep our boats and nets?"
Fishermen and environmental groups have filed a petition against the sealink with the National Green Tribunal (NGT), a special court handling environmental cases.
The court has ruled in favour of kolis in some earlier cases, and is becoming an important way to appeal the CRZ, said Menon.
"But it is not an easy option. They have to mobilise, and it takes time and money," she said.
The CRZ notification comes as fishermen have to go further out to sea for a decent catch, and more are turning to other means to supplement falling incomes.
Mumbai fishermen have called for the 12-mile nautical limit to be increased to improve their catch.
They have also long demanded that the koliwadas be mapped and given protection in the CRZ III category which will preserve the settlements while allowing for redevelopment.
The kolis also want to be recognised as indigenous people, so their land and rights are better protected.
But this is a politically fraught issue, even though India's newly elected president, Ram Nath Kovind, is a Dalit koli.
The federal government has earmarked more than 12 billion rupees ($188 million) for developing tourism at India's beaches.
Maharashtra Revenue Minister Chandrakant Patil said a committee has been set up to demarcate Mumbai's koliwadas.
For now, the kolis in Versova are celebrating their return to the sea with feasting, song and dance that reminds the community of their long history in the city.
"Mumbai began as a fishing village - this is its culture, its history, its tradition," said Tapke.
"We protect the sea, the coast, the marine life; now our lives, our livelihoods are threatened because they want to give our land to movie stars and wealthy people who want sea views and beach sports." - Thomson Reuters Foundation
