Abstract
An attempt was made to evaluate the biochemical
composition of myctophid fishes Diaphus watasei
and Myctophum obtusirostre collected from Arabian
Sea (8°30’50"N - 9°07’50"N lat and 75°49’20"E -
75°58’60"E long). The moisture content in D. watasei
was significantly lower (63.19 ± 0.47%) compared to
M. obtusirostre (71.32%), while fat content was
significantly higher in D. watasei (15.13%) compared
to M obtusirostre (3.54%). Protein also comprised
significant proportions in these myctophids, contributing
21.40% in D. watasei and 22.64% in M.
obtusirostre, with substantial amount of essential
amino acids. The foremost amino acid was glutamic
acid in both the species. Ash content was significantly
higher in M. obtusirostre (3.06%) compared to
D. watasei (1.33%). The present study indicates that
both species contain good quantity of essential
amino acids required for human nutrition.
