After depending on the exotic shrimp species Penaeus vannamei, which is prone to disease outbreak, aqua culturists in the country have opted for Indian white shrimp as it has proven to be more robust and resistant to diseases.
This native species will be promoted as an alternative to exotic species under the Make in India program.
“It has performed very well in terms of growth and disease resistance under culture conditions and has surpassed the growth of P Vannamei during the first two and half months of culture though it is non- Specific Pathogen Free(SPF) and has not been subjected to any selective breeding”, said Akshya Panigrahi, principal scientist at the Central Institute of Brackish water Aquaculture( CIBA).
P.vannamei, a pacific white shrimp, was introduced in 2009 after recurrent outbreaks of disease led to loss in the production of another Indian species P.monodon.
“Now P.vannamei has also become a victim of many viral, bacterial and parasitic disease and suffered slow growth syndrome,” said Mr Panigrahi, who led a research on upgrading of breeding and culture of Indian white shrimp.
Successful farming trials of P.indicus have been conducted in six maritime states Odisha, West Bengal, Andhra Pradesh, Tamil Nadu, Kerala and Gujarat under the National fisheries Development Board (NFDB).
The results were encouraging as the productivity level ranged between three tonnes and six tonnes per hectare.
On August 3,the farmers’ group signed a Memorandum of Understanding(MoU) with the CIBA for rearing the Indian white shrimp. CIBA Director KK Vijayan said there was an urgent need to promote the farming of native indigenous species along with the exotic P.Vannamei.
Mr.Panigrahi said promotion of P.indicus would dispense with the need for depending on other countries for brood stock.
“P.indicus is available all over the Indian coast and breeding of the species is also easy,” he explained.
“Native species like P.monodon has become rare after the introduction of P.vannamei,” he said.
CIBA has submitted a project report to the Indian government for development of Indian white shrimp.
It envisages developing a total of 25,000 hectares and additional production of 1.5 lakh tonnes of native shrimp.
