Description The average annual estimated catch of lizardfishes off Visakhapatnam is 229 t,
which formed 5.3% of the total landings during the period 1990-2001. Five species
of lizardfishes are landed of which, Saurida undosquamis and S. tumbil
are the dominant and contributed 88% to the total lizardfish landings of small
trawlers. The fishery, biology and some aspects of population dynamics of S.
undosquamis are studied. The estimated asymptotic length (L
) and growth
constant (K) in S. undosquamis are 395 mm and 0.31 year –1 respectively. The
fish attained maturity at 230 mm, with spawning period extending from October
to March. The estimated mortality rates Z, F, and M in the species are 1.81,
1.05 and 0.76 respectively. The exploitation rate (E) of S.undosquamis is 0.58.
