Detrodigest

In fin and shellfish culture system hypolimnion of pond bottom is the most dynamic micro-ecosystem, which precisely determines the fate of grow outs in terms of production and onset of diseases. During the culture period, this thin sediment water interface is continuously modified with the deposition of un-eaten feed, faecal matter, moults, dead phyto or zooplankton etc. Accumulation of these detritus trough out the pond or in pockets leads to anoxic conditions paving the way for ammonia and hydrogen sulphide production, the two most toxic gases in aquaculture systems. Apart from aerating the water columns, another method to do away with the detritus is to apply highly efficient detritus degrading bacteria so as to prevent the accumulation of the former, avoiding massive dissolved oxygen demand. With this objective, a novel microbial preparation composed of Bacillus sp. has been designed for Indian Aquaculture sector and technically named as 'DETRODIGEST'. read more>>


Enterotrophotic

Enterotrophotic is a scientific blend of Bacillus cereus sensu lato (MCCB 101) (Genbank accession. no. EF 062509 and Arthrobacter nicotianae (Genbank accession no. EU402968). (MCCB 104) isolated from marine environment and characterized for application as gut probiotic. They control Vibrio in shrimp/prawn intestine by way antagonistic activity mediated by an extracellular anti-vibrio molecule and enhances feed acceptance and digestion by way of producing hydrolytic enzymes. read more>>


PS-1

Probiotics in shrimp culture have an outstanding positive impact in maintaining general health of the culture system, which includes both the animals and environment. 

Most of the probiotic preparations now available in India are the ones developed in other countries and imported as such or produced in India utilizing the organisms isolated from other countries. It is the case with the organisms isolated from unrelated environment say for example freshwater, soil and sewage. Because of these reasons the efficacy of such organisms in Indian aquaculture conditions happens to be much doubtful.

Considering this drawback with the available probiotic preparation this Centre had taken up a comprehensive research programme aiming at developing indigenous probiotics much needed for the Indian aquaculture and especially for shrimp culture. One among such products which the Centre could bring out was the PS –1. The preparation contains different Pseudomonas strains for Marine, Brackish and freshwater systems. read more>>
