Abstract
The examination of genetic variation of wild Penaeid population in Tamil Nadu which is the location of south east coast
region of India, using Randomly amplified polymorphic DNA analysis as DNA marker. The important penaeid species like
Fenneropenaeus indicus
,
Peaneus semisulcatus
,
Penaeus monodon
were collected at
different geographical location such as Chennai,
Nagapattinam, Pudukkottai, Ramnathapuram and Tuticorin, but
P.monodon
not obtained from Tuticorin. For RAPD analysis, 15
primer were used, among which 3, 4, and 6 primers are worked well for
F. indicus
,
P. semisulcatus
and
P. monodon
respectively. The
result of this study, genetic variation 6 %-30 % for
F. indicus
, 16 %-49 %
for
P. semisulcatus
16 %-51 %
for
P. monodon
.
As
conclusion, from the pattern of genetic diversity of three penaeid population could be considered that moderate to high and maximum
three population stocks are there with in collected area.

are cultured, among
which first two are mostly cultivable due to supplying
of seed from hatcheries, traditionally which enter
along the tidal water also cultured. The estimated
brackish water area suitable for undertaking shrimp
cultivation in India is around 11.91 lakh ha. spread
over 10 states and union territories such as West
Bengal, Orissa, Andhra Pradesh, Tamil Nadu,
Pondicherry, Kerala, Karnataka, Goa, Maharashtra
and Gujarat. Of this only around 1.356 lakh ha are
under shrimp farming now. The state with high shrimp
culture farms are Andhra Pradesh, Tamil Nadu, and
Orissa, east coast culture are higher than west coast.
Provide employment opportunities to coastal rural
population and to earn valuable foreign exchange.
The over exploitation of shrimp from Indian coastal
waters and the ever increasing demand for shrimp in
the world market has resulted in the wide gap between
the demand and supply. This has necessitated the need
for exploring newer avenues for increasing shrimp
production. Tamilnadu situated on the south east of
Peninsular India is about 130 000 Sq.km. The length
of its Coastline is about 1 050 km with its significant
portion on the east coast bordering Bay of Bengal.
Tamil Nadu is having the second longest coastline in
the country with rich natural resources in coastal areas
for coastal aqua farming. The total estimated brackish
water area of Tamil Nadu is about 56 000 ha. The total
area under shrimp farming is 4 455 ha. out of which 3
178
ha. are creek based and 1 277 ha. are sea based.
The present culture is 4 455 ha. Which is only 30 per
cent of the estimated potential area of 14 880 ha.
readily available for shrimp farm development. Hence
there is a wide scope for land based costal aquaculture
development in Tamil Nadu. The district-wise

Population genetic have proven valuable for estimating
stock boundaries and genetic variability of wild
shrimp population for fisheries (Benzie, 2000) Genetic
distances between any pair of individuals of same
group are smaller than those between pair of specimen
any two geographical region (Aubert and Lightner, 2000).
Species are often composed of discrete breeding units
