Abstract
The present study entitled 11Economics of
Brackish water prawn culture in Nellore district of
Andhra Pradesh was undertaken mainly to study costs and
returns of prawn farming, and resource use efficiency
along with marketing aspects. The study was undertaken
in Nellore district of Andhra Pradesh, taking the entire
district as sample area. Of the total 52 prawn farms
existing, 40 farms were selected and stratified into two
groups: small farms (below 4.8 ha) and large farms
(above 4.8 ha). In each group 20 farms were selected,
making a total sample of 40 prawn farms. Survey method
was adopted to elicit the response from the respondents
(prawn farmers) through suitably designed pre-tested
schedules. In order to measure the efficiency of the
resources used, analytical tools such as tabular
analysis and the Cobb-Douglas production function were
employed. Break-even analysis was carried out to know
the profitability of the business.
Human labour requirement per hectare was higher
in large farms (359 mandays) than in small farms (317
mandays). The total cost of production per hectare of
prawn farm was ~. 88,411.24 in case of small farms and
~. 84,648.42 in large farms, exhibiting an inverse
relationship.
An inverse relationship was also observed
between cost concepts (Cost A Cost B and Cost C) and
size of the farm. Net income per hectare was higher in
large farms (~. 50,978.28) and lower in small farms (~.
24,865.16). Farm business income, farm labour income,
farm investment income exhibited a direct relationship
with increasing farm size. Large size group registered
a higher input-output ratio (1:60) than the small farms
(1.28).
Results of the Cobb-Douglas production function
analysis indicate that human labour had the significant
influence on output in both the size groups. Seed in
number in small farms and establishment cost, feed cost,
and power cost in large farms have a significant
influence on output. The MVP/MFC ratio of all
significant variables indicates a greater p'otentiali ty
for further investment in both the size groups. Results of the Break-even analysis reveal that
t~ break-even output is less (229.29 kg) in large farms
than in small farms (280.97 kg).
The study of the price spread reveals that
producer's share in consumer's rupee was 57.50 per cent.
Marketing cost incurred by exporting units was 16.28
per cent of the consumer's rupee, and the margins
obtained by exporting units was 25.62 per cent of the
consumer's rupee.
From the present study it could be inferred that
brackishwater prawn production is capital intensive,
requires latest technological innovations and a better
marketing system along with adequate credit facilities
for boosting exports to earn more foreign exchange to
the Indian economy.
