Description The lizardfishes form an important demersal fishery resource off Veraval with
average annual estimated landings of 455 t, forming 0.74% of the total trawl
production. Two species viz. Saurida tumbil and S. undosquamis contributed
to the fishery of which, S. tumbil formed 85% of the lizardfish landings.
Asymptotic length (L∞) and growth coefficient (K) estimated for S. tumbil are
577 mm and 0.70 y-1 respectively and the size at first capture (tc) is 202 mm.
The estimated mortality rates Z, F and M are 3.46 y-1, 2.30 y-1 and 1.16 y-1
respectively. The exploitation ratio (E) and Exploitation rate (U) were estimated
separately as 0.66 and 0.64 respectively. The yield per recruit study shows
that the species has reached close to the optimum level of exploitation in the
present fishing ground. The annual estimated stock is 587 t.
