The intertidal zones of different koliwadas of Mumbai exhibit a diversity of ecologies. Worli Koliwada has rocky shores whereas Trombay Koliwada has a sticky mud called, ‘chikhal’. The sticky quicksand is brown at the surface but the layers underneath turn mat-black, especially near inlets of sewage.

Trombay’s chikhal holds a growing wet mangrove forest, home to multiple living organisms. These include older occupants like crabs, mudskippers and snails along with a burgeoning population of newer occupants, like flamingos.

The chikhal’s form and composition changes every day and every season with the rhythm of the tides, while accumulating plastic, glass, and all sorts of pollutants that the sea and land send its way.

The ever-rising chikhal of this coastal village is interacting, reacting, and changing its texture with the changes in the environment around it.

The fishers of Trombay have co-existed with this stretch in-between the sea and the land, and its unique ecology has influenced Trombay’s fishing practices. Crabs are one species that the chikhal hosts so abundantly as to leave traces of crabs almost everywhere in Trombay! They are seen crawling throughout the market and the village, integral to Trombay’s wetscape. Crabs that are rejected for their small size or deceased are often left at the market's periphery for composters to collect.

As a result, the marketplace is often teeming with tiny crabs scuttling toward the sea. Some fortunate ones manage to reach the water, while others are crushed or become prey to birds like crows. Trombay’s fishers employ five (boat and non-boat) crab fishing methods in the chikhal’s according to the different seasons. Men, women, children, everyone has found a way to catch crabs in this patch which is neither land nor sea but both land and sea.

Trombay is known not just for its creek prawns and javla, but also its crabs, nevti (mudskippers), and kala kolim (black prawns) in the chikhal and salt pans around it. During the bustling morning  market auction in Trombay, avid customers, especially locals, flock to acquire the delicacy of crabs.

Crabs are a lucrative catch, fetching prices ranging from Rs. 600 to 2000 depending on their weight. Previously, Trombay was known for both the khari chimbori and gori chimbori species. However, gori chimbori has become exceedingly rare in the chikhal of recent times.

Pushpa and Indubai in their 60s, are the last remaining women in Trombay, brave enough to venture into the chikhal of the wet mangrove forest to catch crabs and mudskippers.

They spend hours scanning the surface for the crab’s telltale trail marks and gauging the size of the nest hole for the presence of matured crabs to forage – all while effortlessly gliding over the quicksand, a tacit skill that was practiced by numerous women in the past.

They wrap one hand in a cloth to avoid the crab bites and insert it deep inside the crab holes until their bodies lean flat on the chikhal. They catch hold of the crab, pull it out, tie its pincers, and collect it in a bag.

In case of a crab bite, they use their teeth to break off the pincer as it won't release its vice-like grip otherwise. The bag, the cloth, and their bodies are all the tools these handpickers need to earn a daily income of around Rs. 1000.

The construction of concrete jetties and bridges on both sides of the Trombay Koliwada Thane Creek however have thickened and changed the texture of Trombay’s chikhal. Not just the toxins and the increasing depth but also the pieces of broken glass are making this livelihood more physically challenging with each passing day.

This has caused many women to exit this profession or switch their fishing practice from crab to other species.

While all other women except Pushpa and Indubai have left this generational livelihood, women are still the face of the retail market for crabs. They purchase crabs wholesale from male crab fishers or from a tribe called Kakori who specializes in catching crabs in significant quantities.

While many men pursue crab fishing as a part-time occupation, it's rare to find a man selling their catch at the Trombay wholesale market. Instead, most of them prefer to sell directly to women vendors or hand it over to their wives who then take care of the market aspect.

The various fishing gear employed by men for catching crabs include the "fag" which involves small round nets placed in the chikhal with a chicken foot used as bait at the center.

Another is the "pagoli," where multiple baits are attached to a long string laid out in the chikhal.

There's also the "perya" where a team of two, pulls a lengthy net on both ends in the shallow waters of the chikhal.

Elder members of the village often reminisce nostalgically about crabs that hold a special place in their memories. Handpicking crabs in the chikhal and selling them in the market used to be a means of earning pocket money as children. Some even contributed to their family income through this practice, marking their early entry into fishing.

"The art was to catch the crab carefully, preventing it from biting. When I used to pick crabs with my friends if someone got bitten, the kid would yell in pain, and we'd all burst out laughing! Those are cherished memories from our childhood," shared the current Chairman of Trombay’s fishers cooperative society.

However, these stories belong to the past. The children who learned their earliest fishing lessons through crab hunting are now old, and the new generation of children either aren't permitted to enter the toxic chikhal or simply aren't interested in doing so.

While Indubai and Pushpa have remained in this practice throughout their lives, others have moved on to become boat owners, while still others have departed from their traditional fishing occupation.

The presence of industrial pollutants, waste from dumping grounds, and plastic wrappers suffocating the crabs within their nests has significantly reduced the number of crabs in Trombay. Those who continue crab fishing might indeed represent the last generation engaging in this occupation.

Though the rising chikhal has had a detrimental effect on crabs, it has worked in favor of flamingoes and mangroves. Trombay has been witnessing flocks of flamingoes visiting their Koliwada like never before. The flamingoes that feed on nevti, a local delicacy of mudskipper have severely affected the quantity and quality of this fish. For this reason, the flamingoes that fascinate Mumbai do not make the fishers of Trombay as happy as the rest of the city.

The fishers of Trombay have long called for building a floating jetty instead of a concrete one to control the rise of chikhal but these have gone unheeded. The Bombay Municipal Corporation seems to have other plans for Trombay Koliwada. Trombay’s fishers found this out by reading in the newspapers about the City Corporation’s proposal to start an eco-tourism project there, centered around a flamingo watch tower!

Yes, crabs have also found a small place in this project at a crab pond with turtles along with a Mangrove cafe and kayaking.  

Though the villagers are upset that they found out about this project only through the newspapers, some are also hopeful that it might open up new avenues of livelihood related to tourism. Ferrying tourists, setting up restaurants, and allied tourism businesses hold more prospects for the future given the slow dying of fishing in these parts.

However, how such an ecotourism project might affect different fishers within the community is difficult to foresee.

As mangroves spread in the Koliwada’s fishing commons, the Forest Department declares it a protected zone, restricting its use by fishers, who for so long have been its indigenous custodians. The wet forest is entering the village, the chikhal that holds it is rising, leading to an infestation of flamingoes, and these make way for the Forest department and the municipality to enter the socio-natural, economic, and cultural life-worlds of Trombay’s fishers.

Only time can tell how this project will shape the ecology currently shared by the chikhal, crabs, mangroves, mudskippers, plastic waste, industrial fluids, and now, flamingoes. And where the crabs that are currently everywhere, will go in the future.
