Cochin
The Central Marine Fisheries Research Institute is one of the eight Research Organisations in the the network of Central Fisheries Research Institutes under the Indian Council of Agricultural Research devoted to research , education , training and transfer of technologies in support of development of fisheries in india . CMFRI ' s mandate is to conduct researches on exploited , under - and unexploited marine fisheries resources and fisheries oceanography , to advise on rational exploitation and make forecast of abundance , development and upgradation of technologies for maximising production through mariculture and conducting teaching , training and extension programmes for development of human resources in fisheries .
The Institute with its headquarters at cochin and research and field centres all along the indian coastline , conducts mission - oriented researches in important areas of marine capture and culture fisheries on all - india basis as well as regional basis in addition to making district - wise , species-wise and gear wise production estimates . Besides , the CMFRI also conducts researches on short -term but frontier areas of marine fisheries through ad hoc projects funded by different agencies .
RESEARCH HIGHLIGHTS
Estimating Fish Production
Collection of marine fisheries and making gear-wise , species - wise production estimates is one of the principal tasks of CMFRI . Besides being useful for various developmental and planning purposes , this information serves as an essential input for research in marine capture fisheries and enable formulation of strategies for sustaining production in india during 1996 registered an increase of 6.9% over 1995 with the estimated production at 2 . 41 million tonnes (mt) .
Studying Fishery and Resource Characteristics
The marine fish production as is well-known , is stagnating around 2.3 mt during the past few years and is close to the level of potential yield of of 2.2 mt in the currently exploited ground . The situation warrants close monitoring of the exploitation and develop suitable strategies for sustaining the yields on an economic level using the advise emanating from the results of research . The research projects in the capture sector are implemented to meet this requirements .
Monitoring the Fishery Environment
Sea truth data collected during premonsoon , southwest monsoon and postmonsoon seasons confirmed the presence of upwelling in the area between Mangalore and Kasargod during southwest monsoon season .
Remote Sensing and Potential Fishing Zones (PFZs)
The validation of PFZ forecasts in the minicoy region yielded positive results with higher yield of skipjack tuna in the pole and line fishery . Off Kerala coast relatively higher catches by pursuing fishing and gill netting suggest reliability of PFZ forecast through satellite imageries .
Mariculture Technologies
In the seed production of portunus pelaginus , 14 beeders produced 87 lakh zoeae of which 14.8 lakh were reared through 5 zoeal stages , megalopa and first instar .
Upgradation , location testing and transfer of bivalve culture technology
Grafting experiments were carried out with different species of pearl oyster to obtain pearls of improved quality . The experiments using graft tissue of fucata in same species produced good quality pearls .
Improving mariculture technologies
nutrition : The protein content of dry cassava chips fermented using fungi increased from 1.6% to 10.8%. similarly the fermented ( using fungi ) and dried cashew fruit showed increase in protein 2.44% to 13.08% .
Physiology : The edible oyster and clam subjected to different salinities for 45 days showed that the highest survival rate of Crassostrea madrasensis of 85% could be obtained at 20 and 25 ppt salinity . in meretrix casta the maximum survival of 75% and maximum weight gain of 7.18% were at 20 ppt .
Pathology : Histopathological study of white spot disease syndrome (wss) in P. monodon revealed intra nuclear inclusion bodies on mesodermal and epidermal tissues . for the first time a protozoan was reported in the inter and intra tubular spaces of hepatopancreas .
Genetics : studies on Rastrelliger kanagurta and sardinella longiceps revealed that muscle proteins of former species and MtDNA of both the species are potential genetic markers for evaluation of intraspecific genetic variability .
