Technologies/ concepts/ findings

  • Protocol culture of black tiger prawn, Penaeus Monodon (Fabricius) in open sea floating cage.
  • Culture of Asian sea bass, Lates Calcarifer (Bloch,1790) in open sea floating cage off Kakinada coast in the bay of Bengal,
  • Development of nursery rearing system for Asian sea bass, Lates Calcarifer (Bloch,1790) in the floating cage in sea.
  • Open sea floating cage- a device for domestication and brood stock development of greasy grouper, Epinephelus tauvina (Forsskal,1775) off Visakhapatnam in the Bay of Bengal.
  • Identification of Arachidonic acid from littoral Oligochaete Pontodrilus Bermudensis as Penaeid shrimp maturation stimulator.
  • Protocol for culture of littoral Oligochaete Pontodrilus Bermudensis
  • Publications: International-22, National-57, Special publications-4, book chapters-39, posters-2 and others-109.
  • Books: 1. Handbook of Prawns, 2.Handbook of Marine Prawns of India
  • MSY and FMSY for shrimps targeted by trawlers in Maharashtra were estimated as 44,647 t and 7.75 million trawling hours. The optimum number of trawlers in the state was computed at 2,778 as against present fleet of 5,613, indicating overcapacity in the trawling fleet.
  • Average annual all India trawl landings for the period 2008-2011 is 17,21,000 t. which formed 51 % of the total marine fish landings in the country.

  • Farming technologies for mussels, oysters, pearl oysters, clams.
  • Commercial mussel and oyster farming was extended to new areas in Kerala and Karnataka and the 2011 production was estimated at 12,950 tonnes.
  • Controlled breeding and spat production in Pinctada fucata, Crassostrea madrasensis, Perna viridis, Perna indica, Marcia opima, Paphia malabarica, Meretrix meretrix, Placuna placenta.
  • An automatic mussel seeder developed for seeding mussels on to ropes.
  • Several oyster and oceanic squid products developed in collaboration with NIFPHATT which were test marketed in Kochi successfully
  • Blacklip pearl oyster spat production process, farming protocols and pearl and mabe pearl production technologies
  • Depuration protocols for oysters and clams
  • Development of live oyster value chain, Depuration display unit and protocols developed for live oyster consumption in high end restaurants.
  • Process/protocols for steam shucking of oysters and clams (Patent application made in 2013).
  • Developed all technological know-how for the launch of the oceanic squid value chain including fishing methods, area and season of abundance, stock abundance in relation to environmental factors, MSY and plan for exploitation.
  • Determined that FAD fishing for cuttlefish is destructive to the stock and as per CMFRI advice the Government of Karnataka has banned the fishing practice.
  • Developed Fishery Management Plan (FMP) for Ashtamudi Lake short-neck clam fisheries, based on which the Kollam District administration has formed the Ashtamudi Lake Clam Fisheries Governance Council (ACFGC) which is a fisheries co-management council.
  • Responsible for science back-up for MSC ecolabel for the Ashtamudi Lake short- neck clam fishery - which is the first certified fishery in the country.
  • Developed advisories (66 recommendations) for management of marine fisheries of Kerala including extension of trawl ban and new ban for ring seiners
