Habitat: Forests
Larger than a domestic cat, the Fishing Cat is well adapted
to catching fish, its primary prey. They have a deep-chested body with short legs, a big, broad head, and a
short tail. The short, coarse fur is a grizzled grey in colour, and tinged with brown. There are elongated dark
brown spots arranged in longitudinal rows extending over the entire body. There are six to
eight dark lines running from
the forehead to the neck, and the underparts are whitish and spotted. The head is relatively big and broad,
the muzzle somewhat elongated. Their eyes have greenish irises, and the ears are rather short and rounded,
with black on the backand prominent white spots in the middle. The legs are short with the forelimbs having
two distinct elbow bars. The tail is less than half the head and body length, is relatively thick, and has a
series of incomplete rings with a black tip.
Their front feet are partially webbed and their claw tips
protrude from their sheaths even when retracted, leaving a signature track imprint.
One remarkable feature is the layered structure of their
fur, a crucial adaptation to life in the water. Next to the skin lies a layer of short hair so dense that water
cannot penetrate it. Like snug-fitting thermal underwear, this coat helps keep the animal warm and dry even
during chilly fishing expeditions. Sprouting up through the first coat is another layer of long guard hairs
which gives the cat its pattern and glossy sheen.
Distribution
Fishing Cats have a discontinuous distribution in South East Asia including the islands of Java,
Sumatra and Peninsular Malaysia, northern India and Sri Lanka.
These cats are strongly
associated with wetland, and are typically found in a number of water habitats, including marshy
thickets, mangrove swamps, and densely vegetated areas along rivers and streams. They have been recorded
at elevations up to 1,525 metres in the Indian Himalayas where they frequent dense vegetation near rivers and
streams. They have also been observed in degraded habitat such as near aquaculture ponds.
A study on the island of Java found that Fishing Cats
inhabit coastal wetlands less than 15 km from the ocean, no higher than 20 metres above sea level.
Another radio telemetry study in
a Nepal national park found Fishing Cats were active only at night, and spent most of their time in dense
grassland, sometimes away from water. Home ranges of three females were 4-6 km2, and that of a
single male was 16-22 km2.
Their presence in
Cambodia was only confirmed in 2009, and their distribution in that country is poorly known. The
identification of Fishing Cats there is difficult, due to their resemblance to the large geographical size
variations of the Leopard Cat Prionailurus bengalensis. Juveniles
of the two species are visually very similar.
Ecology
Fishing Cats are another feline that contradicts the belief that cats don’t like water. They are strong swimmers, and can
cover long distances underwater. They have been seen wading and swimming in shallow water, hunting for a variety of aquatic
prey. They often hunt for fish while fully immersed in water, and have
been seen catching fish by plunging their heads under water, and flicking or scooping them out with their paws. One
report describes them catching waterfowl by swimming underwater and seizing their legs from
beneath.
A one year study of scat analysis in India revealed that 76% of
their food was fish, with some birds, insects and rodents also taken. Grass was present in the diet in all months
except August, during the monsoon season.
Fishing Cats are capable of
taking large mammal prey, and have been seen scavenging livestock carcasses and
Tiger Panthera tigris kills. They are thought to be primarily nocturnal but little is known of their
behaviour in the wild.
Reproduction
These cats are assumed to be polyestrous year round. They
are said to have a characteristic mating call, but the call has not been described. Dens are constructed in
dense shrubbery, reeds, hollow trees, in rocky crevices, or in other secluded locations. Kittens have been seen
in the wild in April and June, and have been born at the Philadelphia Zoo in March and August. One to four,
usually two, kittens are born after a 63 - 70 day gestation, and weigh around 170 grams at birth.
Their eyes are open by 16 days, meat is taken around 53 days,
and the kittens are weaned between four and six months. Adult size is attained at eight to
nine months, and the young are
independent between 12 - 18 months. It is thought that in the
wild the adult male may help
with the care and supervision of the young, but this is unverified. Captive individuals have lived to 12
years of age.
Conservation
Locally common in some areas of eastern India and
Bangladesh, they have become increasingly difficult to locate throughout the remainder of their range. The
scarcity of recent records suggests that over the past decade, they have undergone a serious and significant
population decline. Even in protected wetlands and former Fishing Cat study areas, researchers have been unable
to document their presence.
On the island of Java, their prime mangrove habitat now
covers less than 11% of the original area. Pollution by pesticide run-off from rice fields threatens these
wetland predators who may accumulate toxins from their prey species. Fishing Cats on Java are also hunted and
caught in fish traps.
Poachers in Cambodia report the Fishing Cat is easily
hunted for food, and protected areas contain evidence of widespread hunting where noose snares are commonly
encountered.
Wetland destruction is the primary threat facing this
species, as over 50% of Asian wetlands are under threat and disappearing. Indiscriminate trapping, snaring and
poisoning are also taking a toll. Fishing Cats
are considered a food item in
many areas of their range, and are also persecuted for taking domestic
stock.
A long-term study in Thailand found 9 of
their 17 radio-collared cats had disappeared or been killed by poachers. Working with government officials,
the researchers have had the Fishing Cat made part of the provincial natural
resources protection policy, and an extensive public awareness conservation campaign is
underway.
Fishing Cats were upgraded from Vulnerable to Endangered in
2008.
Legends
At one time, missionaries and local people mistakenly
reported this feline as a 'kidnapper', snatching infants from their cradles while they were
sleeping.
