Infectious diseases are a major problem in shrimp aquaculture. Strict
biosecurity measures should be implemented to control horizontal and vertical
transmission of pathogens. However, implementation of biosecurity measures
is neither consistent nor uniform. In this study, we generate baseline
information on the variety and degree of adoption of biosecurity measures in
shrimp hatcheries in India. Data were collected from 96 hatcheries using a
structured questionnaire. Hatcheries were classified as small (102 million
seed/annum), according to seed production capacity. Biosecurity measures
were categorized as personnel, operational, or screening for pathogens in
broodfish and live feeds. The highest biosecurity implementation rate of
personnel procedures was 50% in small and medium hatcheries and 40% in
large hatcheries. The highest implementation rate of operational measures
was 63% in small hatcheries, 84% in medium, and 47% in large. The highest
rates for screening of pathogens was 50% in small and large hatcheries and
25% in medium. The only measures implemented in all 96 hatcheries were
use of foot baths, disinfecting hands after handling brooders/larvae/live feed,
and virus screening of broodfish, indicating consistent practice in all
hatcheries and an implementation gap of 0%. A lack of understanding,
reluctance to implement, and the need for large financial inputs are
responsible for the poor implementation of biosecurity measures. The baseline
information generated in this study exposes the challenges in implementation
of biosecurity in shrimp hatcheries. The collected data can be used to further
refine and implement biosecurity practices.
