Nutritive values of fishes landed in the East coast of Tamil Nadu

  • Nutritive values including protein, fat, ash, cholesterol, calcium, iron and phosphorus contents of 80 fishes were tested. Protein varied from 8.49 to 26.14%; lipids from 0.13 to 14.72%; cholesterol from 4.86 to 180.52 mg%;  calcium from 64.24 to 1887.10 mg%;  iron from 0.06 to 28.46 mg% and phosphorus from 15.25 to 443.26%. Lethrinus elongatus had high protein, while
  • Leiognathus dussumiera had high lipids.  Cholesterol was high in the squid Loligo duvaceli.
  • Fatty acid compositions of 53 fishes were tested by the gas chromatography. DHA was found to be higher in Pellona ditchela (29% of fatty acid), Stolephorus commersonii (20%) and S. devisi (18%). EPA was higher in Stolephorus devisi (11.4%), S.commersonii (9.9%), Portunus pelagicus (9.8%), Dussumeria acuta (9.7%) and Leiognathus dussumeri (9.6%). Therefore, small sized pelagic fishes are therefore good sources of DHA and EPA.
  • Instruments such as HPLC, GLC, thermalcyler, gel documentation system, refrigerated centrifuge, etc. were added to create facilities for testing the nutritional quality of fishes.


Application of information and communication technologies (ICTs) in marine capture fisheries of Andhra Pradesh

  • With respect to the response to ICT tools, the majority of fishermen who operate mechanized fishing vessels perceived the ICT tools to be  reliable, complex to use, costly, useful, very much needed by them and more  willing to use the ICT  tools in fisheries.
  • A majority of the fishermen respondents had medium level of positive perception about the application of ICT tools. Among the various ICT tools owned/operated by the respondents, mobile, TV, VHF, Echo sounder and GPS were the popular ones.
