INTRODUCTION
The mollusks form the second most diverse group of animals
after arthropods—with estimates of 80,000 to 100,000
described species (Strong et al., 2008). Freshwater mollusks
inhabit every continent except Antarctica and occur in nearly
all inland aquatic habitats. The freshwater mollusks are
common inhabitants of inland freshwater bodies such as rivers,
lakes, dams, wetlands, backwaters, streams, canals, ponds
and seasonal water ditches (Cummings and Lydeard, 2019).
Most live submerged, and many are specialized for particular
habitats—aquatic vegetation, stones, rocks, wood, and other
solid surfaces, or soft sediment. India, with a mere 2.4% of the
world’s area, accounts for 7.31% of the global faunal total
with a faunal species count of 89,451 species (Alfred, 1998).
The malacofauna of India is represented by 5070 species
which include 3371 species of marine mollusks and 1671
species of non-marine mollusks. According to recent estimates,
India has about 203 freshwater mollusk species belonging to
59 genera and 26 families (Ramakrishna and Dey, 2007). A
number of distinguished malacologists such as
Annandale, Prashad, Rao, and many others from the
Zoological Survey of India have contributed a lot to our
knowledge of freshwater mollusks of the Indian subcontinent
(Subba Rao, 1989). The significant contributions to
the malacofauna of the Maharashtra state were made by a
number of researchers (Tonapi and Mulherkar, 1963; Tonapi,
1971, 1980; Nagabhushnam and Kulkarni, 1973; Surya Rao
et al., 2002; Patil and Talmale, 2005). However, after
Patil and Talmale (2005), there is no updated information on
this group in Maharashtra.
The Newasa tahsil within Ahmednagar district is part of the
upper Godavari basin and drained by rivers such as the
Godavari, Pravara, and Mula. The Newasa tahsil also has
many seasonal ponds, irrigation canals, dam backwaters, and
seasonal streams. The region, thus, has vast potential for
harboring freshwater mollusks. The perusal of literature
shows that there is no published record of study on
the malacofauna of the Newasa tahsil. The information on
malacofaunal resources is highly useful in the taxonomy,
distribution, conservation, and management of the fauna. A
number of freshwater gastropods serve as a vector for
trematode parasites (Agrawal et al., 2000a, b). The information
on the diversity and distribution of vector snails is pivotal in
formulating strategies for their control and management. In
light of this, the present investigation was undertaken to study
the diversity, distribution, and importance of
freshwater malacofauna of selected water bodies
from Newasa tahsil.
MATERIALS AND METHODS
Study area
Newasa tahsil is an administrative block within Ahmednagar
district located in the state of Maharashtra with an area of 1343
km2 [Fig. 1]. It is one of the most irrigated areas of Ahmednagar
district and is well known in the state for its vast sugarcane
fields. The Newasa tahsil area is drained by rivers such as the
Godavari, Pravara, and Mula.
ABSTRACT
The Newasa tahsil is an important administrative block within Ahmednagar district, Maharashtra. Although
small in area, the Newasa tahsil is drained by the Godavari, the longest river of South India. The tahsil is known
for its vast sugarcane fields and sugar factories. This area also has a rich network of canals, seasonal ponds, and
backwaters of the famous Nathsagar dam. The area has great potential for harboring aquatic mollusks. With no
record of any previous study on malacofauna, the present study was undertaken to investigate the diversity,
distribution and importance of the freshwater malacofauna of Newasa tahsil. The study included a
malacofaunal survey of 9 different water bodies which included rivers, canals, ponds, and lakes. A total of 17
different species of freshwater mollusks were recorded. The mollusks species recorded include 12 gastropods
representing 5 families and 9 genera. The bivalves recorded include 5 species representing 2 families and 2
genera. The study is highlighted by the new locality record for Amerianna carinata as it is recorded for the first
time from the Godavari river. Many of the gastropod species recorded in the present study have been reported
earlier to be of medical, veterinary, and economic importance.

The study area is also having a good network of irrigation
canals, backwater, lakes, ponds, seasonal streams, and ditches.
The present investigation included the malacological survey
of 9 freshwater bodies from the study area [Table 1].
Collection and Maintenance: Malacological surveys were
carried as per the methodology described in handbooks on
freshwater mollusks of India by Zoological Survey of India
(Subba Rao, 1989; Ramakrishna and Dey, 2007). The mollusk
specimens were collected using the aquatic net or directly
by handpicking. The collected specimens were preserved in
70% ethanol. The specimen bottles were labeled with respect
to the date of collection, name of the water body, and name of
the collector.
Identification
The snail and bivalve specimens were sent to the Zoological
Survey of India, Western regional station, Pune, for
identification. The voucher specimens were deposited in
the ZSI, WRS, Pune. The experts from ZSI, identified mollusk
specimens using identification keys in the handbook on the
freshwater mollusks of India (Ramakrishna and Dey, 2007).
The mollusk specimens were photographed by placing them
upon a laminated graph paper with Nikon D5100 DSLR
camera.
RESULTS AND DISCUSSION
The trematode parasites use snails as intermediate hosts
and snails of the genus Bulinus, Biomphalaria,
and Oncomelania are common vectors of schistosomiasis in
African countries. At least 7 gastropod species recorded from
the study area are of medical and veterinary importance.
The gastropods R. acuminata, R. luteola, I. exustus, G.
Convexiusculus, M. tuberculata, T. scabra and T. granifera
have been reported to serve as intermediate hosts
for trematode parasites of medical and veterinary
importance(Agrawal et al., 1991; Pinto and de Melo, 2011;
Agrawal et al., 2000a,b;Jauhari and Nongthombam, 2014).
The snail M. tuberculata has been shown to serve as a vector
for 30 species of trematodes (Pinto and de Melo, 2011). In
one of the studies, snails R. luteola and I. exustus were found
to harbor cercariae of Schistosoma incognitum,
Orientobilharzia dattai), S. spindale, S. indicum and S. nasale
(Agrawal et al., 1991). A recent study confirms the role of
snails such as I. exustus, M. tuberculata, G. convexiusculus,
and R. acuminata in the transmission of cercarial dermatitis
in India (Jauhari and Nongthombam, 2014). The occurrence
of schistosomiasis in Maharashtra has been reported from
the Ratnagiri district (Gaitonde et al., 1981). In
the Newasa tahsil, like in other parts of the country, it is a

FIRST REPORT ON THE FRESHWATER MALACOFAUNA
mollusks as food by local communities from Newasa tahsil.
The present investigation is the first exclusive report on
freshwater mollusk fauna from the Newasa tahsil of
Ahmednagar district that lies within the upper Godavari basin.
A total of 17 mollusk species were recorded that highlight the
malacofaunal richness of the study area and the suitability of
the study area as a habitat for the mollusks. This is a good
indication that further investigations are needed on the
malacofauna of the region. This study reports a new locality
(i.e., the Godavari river site I, Ahmednagar district), for the
snails Amerianna carinata which was earlier reported for the
first time in India from Pune district of Maharashtra (Subba
Rao et al., 1994). The snail A. carinata was by mistake
identified as new species Bulinus indicus in India (Subba Rao
et al., 1994) which was later corrected by Brown (1997). The
snail A. carinata is native of the Australian region and found
in many parts of the World. All other gastropod species
recorded from the study area have been recorded earlier from
traditional common practice among the farmers to use water
from river and pond as drinking water for their cattle. The
swimming in rivers and ponds is common in summer among
the local population. The local fishermen carry out fishing
activities many times a year. The proximity of people
and cattle with local water bodies creates high chances for
infection by trematode larvae released by snails. However,
there has been no official or published
record regarding schistosomiasis infection in the study area.
Hence, scientific research is highly needed in this regard. Some
of the mollusks from the study area are edible. The two
gastropod species: F. bengalensis and I. dissimilis, and two
bivalve species: L. corrianus and P. caerulea from the study
area has been reported as being used as food in some of the
Indian states (Subba Rao and Dey, 1986; Mahata, 2002;
Ramakrishna and Dey, 2007). However, these edible mollusks
are not used as a source of food by any of the local communities
as per our inquiry. There is no published record of the use of

2005). The bivalves recorded from the study area have also
been reported from water bodies of neighboring districts such
as Pune, Aurangabad and Nashik (Surya Rao et al., 2002; Patil
and Ramakrishna, 2005, Shinde, 2016; Pande et al., 2020)

FIRST REPORT ON THE FRESHWATER MALACOFAUNA
Some of the mollusk species reported from the study area
such as F. bengalensis, I. dissimilis, L. corrianus and P.
corrugata are edible mollusks and used as food in many north-
eastern states of India (Subba Rao and Dey, 1986; Ramakrishna
and Dey, 2007). Many of the gastropods recorded to serve as
vectors for trematodes that cause schistosomiasis and are of
medical importance (Kali, 2015).The snail R. acuminata and
I. exustus reported in the present study are widely distributed
in India (Ramakrishna and Dey, 2007) and are used as model
experimental animals in a variety of fundamental research
(Pande et al., 2009, 2010; Singh et al., 2013).
The work on the malacofauna of the Maharashtra state was
embarked by distinguished malacologists such as Annandale,
Prashad, and Hora (Patil and Ramakrishna, 2005). There is
no recent published record on the freshwater mollusks of
Maharashtra (Patil and Talmale, 2005). The literature on the
diversity, distribution, and conservation status of malacofauna
of the state is limited and scattered. A total of 53 species of
mollusks were reported from Pune district alone (Tonapi and
Mulherkar, 1963; Tonapi, 1971, 1980). In one more study,
about 11 mollusk species were reported from Ujani Wetland
in Pune district (Surya Rao et al., 2002). A total of 27 mollusk
species were recorded from the Nathsagar dam from
Aurangabad district (Patil and Ramakrishna, 2005). However,
the mollusk fauna of other districts of Maharashtra has not
been studied in detail. In light of this background, the present
investigation is the first exclusive report on freshwater mollusk
fauna from of the study area. The results obtained will enrich
the faunal data of Maharashtra state and India. The information
on the diversity, distribution, and medical importance of
malacofauna can be useful in taxonomy, distribution,
conservation of malacofauna. It will also be helpful in
formulating strategies for the control and management of
medically important vector snails.
