ABSTRACT
This study was carried out to investigate the
consumption pattern of frog meat in Ibadan.
Two local government areas in Ibadan city;
Akinyele and Ibadan north were randomly
selected for the study. Structured
questionnaires, field observation test and
personal interviews were used for the study.
Two sets of questionnaires were purposively
administered to two categories of
respondents in the study area. The first set of
questionnaire was administered to all frog
sellers available at the markets in the study
area. The second set of questionnaire was
administered randomly to 50 frog consumers
each from the two local government areas.
In all 27 frog traders and 100 frog
consumers were interviewed in the study
area. Data obtained were analysed using
descriptive statistics. The study revealed that
a total of 100 frog meat consumers sampled
in the study areas acquired about 284752
frogs and consumed 126672 various frog
species annually and that commercialization
of frogs was more in urban (Arisekola and
Bodija) but consumption rate on account of
the 100 consumers sampled was higher in
Ijaiye (rural area). The 27 frog sellers
sampled had a total of 53.5 bags of frog in
their possession at the time of survey.
Hildebrandtia ornate, Hoplobatrachus
occipitalis, Ptychadena pumilio and
Pyxicephalus edulis used for food together
with Bufo pentoni, Ptychadena
mascareniensis, Tomopterna cryptotis and
Amietophrynus regularis used for medicine
and mythic were the eight predominately
consumed frogs species in the study area.
Hoplobatrachus occipitalis mostly utilized
for food is the most commercialized species,
because of its large size and availability.
Frog meat serves as a good source of protein
and income for the inhabitants. But the
unsustainable use of these edible frog
species would have a detrimental effect on
the ecosystem. Hence frog farming and
conservation efforts must be encouraged.

INTRODUCTION
Frogs are transitional animals that
live partly in water and on land, striking a
balance between the two environments; they
belong to the class of vertebrates known as
amphibians (Omonona and Ekpenko, 2011).
They are amphibians in the order Anura
(meaning ‘‘tail-less’’ from Greek an- without; oura, tail), formerly referred to as
Salientia (Latin salere (salio), “to jump”).
The order Anura is the largest of amphibians
containing 5450 species in 48 families (Vitt
and Caldwell, 2009).

Amphibian populations are declining
worldwide; overexploitation is identified as
one of the reasons for the worldwide
amphibian decline (Stuart et al., 2004 and
2008). Niasse et al., (2004) stated that
utilization is the main threat for 281
amphibians species, 54% of these already
listed as vulnerable, endangered or critically
endangered when IUCN Red List categories
are applied. A recent study by Warketin et
al., (2009) summarized alarming data on
numbers of Asian frogs collected for human
consumption while Mohneke (2011)
revealed that a total of two million, seven
hundred and thirty eight thousand six
hundred and ten (2,738,610) various frog
species were collected by thirty two (32)
frog collectors annually in south-west states
of Nigeria.
One of the major obvious effects of
human population increase at global level is
food shortage and Africa lies behind other
developing countries in food production
(Lameed, 2008). This has resulted in a
significant short fall between the production
and supply of animal protein to feed the ever
increasing population (Akpan et al., (2009).
In many African countries (such as Benin,
Burkina Faso, Cameroon, Cote d’Ivoire,
Ghana, Guinea, Namibia, Nigeria, South
Africa and Togo) frogs have always been
collected on a local scale as an essential
source of animal protein (Angulo, 2008;
Mohneke et al., 2009). An increase in the
size of human population tends to increase
the existing pressure on wildlife populations.
Frog species mainly used for food,
medicinal purposes and pet trade in different
parts of the world are normally sourced from
the wild (Mohneke et al., 2011). Farming of
these utilized species of frogs in Africa and
the world as a whole has been generally
neglected whereas the rate of utilization is
continuously increasing.
Most of the frogs utilized in
developed countries are sourced from
developing countries. Consequently, the rate
of exportation of frogs (irrespective of the
conservation status) from developing to
developed countries has been increasing
because of the market created by the high
demand. Onadeko et al., (2011) reported
that frog legs were popular delicacy in
Europe and were even eaten in countries
where it is legally prohibited to hunt frogs.
In some regions of Asia (Indonesia) and
Africa (Nigeria), frogs are referred to as
“jumping chickens,” as the taste is perceived
to be similar to chicken (Altherr et al.,
2011). Their availability, palatability to
humans and the need to meet protein
demand are some of the major reasons why
billions of frogs are consumed annually.
Frogs are also collected for leather
production and souvenirs, pet trade and
cultural reasons, including traditional
medicine (Kusrini and Alford, 2006;
Gonwouo and Rodel, 2008). However,
overexploitation of these resources is one of
the major threats to biodiversity.
Within the past decade, frogs have
become an international trading item,
involving more than 30 countries, and in
1998 the trade on frog species was valued at
approximately USD 48.7 million (Teixeira
et al., 2001). Such exploitation without
planning for the sustainability of these

amphibian species would have direct and
indirect impacts on both frog species and the
ecosystem. Amphibians are important
components in various terrestrial and aquatic
ecosystems and their reduction or
disappearance would have consequence
effect to the ecosystem and other relative
components (Toledo et al., 2007; Mohneke
and Rodel, 2009).
MATERIALS AND METHOD
The study areas were selected using
random sampling technique; two local
government areas; Akinyele and Ibadan
North (40.0%) were randomly selected from
the five local government areas in Ibadan
city. Ibadan city is geographically located on
latitude 7°23' 47'' N and longitude 3°55' 0''
E. Data for the study were obtained through
pre-tested semi-structured questionnaires,
in-depth interviews and field observations.
Two sets of pre-tested semi-structured
questionnaires were administered
purposively to two categories of
respondents. The first set of questionnaire
was administered to all frog sellers (traders)
available at the markets in each of the two
selected local government areas. The second
set of questionnaire was administered
randomly to 50 frog consumers each from
the two local government areas. In all 27
frog traders and 100 frog consumers were
interviewed in the study area while traders
involved in sales of frogs for medicinal
purposes were also interviewed. The
questionnaires were written in English to
avoid communication problems, all
interviews were carried out with the help of
field assistants who speaks the local
languages (Hausa and Yoruba). In general,
the questionnaires comprised questions
eliciting information on the
knowledge/experience the interviewees had
concerning utilization/consumption and
sales of frogs.
RESULTS
Demand and Consumption Rate of Frog
Meat
Results on the demand and
consumption rate of frog meat in Ibadan city
is presented in Table 1, Figure 1 and Figure
2. Table 1 and Figure 1, shows the quantity
of frogs the traders started with, the quantity
in their possession at the time of the survey,
the quantity they usually buy and the
quantity they wished for if they had more
money. Figure 1 reveal that
commercialization of frog meat was high at
Arisekola; where the sellers started the frog
market with 9 bags of frogs and had 16.5
bags of frogs in their possession at the time
of survey and was low at Ojoo; where the
frog sellers started the frog market with 2
bags of frogs and had 4 bags of frogs in their
possession at the time of survey and on
cumulative bases, the entire traders (100%)
started the frog market with 27 bags of
frogs. Although the entire sellers (100%)
acquired a total of 58.5 bags of frogs from
various frog markets, only 53.5 bags were in
their possession at the time of survey. The
traders also showed a great deal of willing to
boast their frog market to a total of 120 bags
on an average of four bags of frogs per
seller, if they had more money. Table 1, also
reveal the quantity of frog meat consumers
acquired at once (5476 pieces), quantity
