Aquaculture and Marine Biotechnology

Programme on biosurfactants, exploration of marine enzymes, bioactive molecules, reproductive biology and cell cycling, plasmid immune response, neuro-peptide synthesis, bioreactors, vaccine development for fish, bacteriophage therapy in improvement of shrimp larvae, oligonucleotide probe for monitoring vibrio counts in hatcheries, genetic characterization of marine organisms, organ development, cell lines from seabass, shrimp genomics and fish nutrition are being implemented. Biosurfactants were screened using marine Acinetobacter genospecies. A prototype for raceway based shrimp production technology was utilized for nursery rearing of shrimp. Studies on occurrence of human pathogenic viruses in coastal marine waters were carried out. Marine cyanobacteria and chlorella species were studied for over expression of superoxide dismutase enzyme useful for bioremediation and salt tolerance.

Bioactive molecules were explored for antibacterial, antiviral and anticancer agents. Role of bacterial plasmid gene was studied in pathogenesis of Epizootic Ulcerative Syndrome and its virulence. Applications with the use of phytase were explored from yeast as an alternate fish feed supplement. Neuro-peptides synthesis was explored from Indian cone snails and conus peptide sequence was worked out. A bioreactor was under development for microbial based treatment system for seafood industrial discharge. Vaccine development for fish for Aeromonas showed promising leads. Bacteriophage therapy in improvement of shrimp larvae was pursued as an alternative to antibiotics in aquaculture. Oligonucleotide probe for monitoring vibrio counts in hatcheries were designed. Organ development and differentiation were studied using perivitelline fluid of Indian Horse Shoe Crab.
