Description Lactarius lactarius, commonly known as false
trevally is exploited mainly by trawlers from the
inshore waters (5-30 m depth) along the Karnataka
coast. Bottom-set gillnets and purseseines also
land minor quantities of whitefish, besides the
indigenous gears operated during monsoon. The
average annual production of false travelly from
multiday trawls operated along Mangalore coast
remained at 416 t during the period from 2000 to
2002. A declining trend in the fishery was noticed
since the year 2000 consequent to reduction in
catch rates and the production reached an all-time
low of 117 t in 2004. Thereafter, the catch rates in
multiday trawl improved significantly from 0.09 kgh–1
in 2004 to an annual average of 0.33 kgh–1 in 2008
(Fig. 1). During the year, 50% of the annual
whitefish landing was observed in October-
November months, when the catch rates increased
from 0.6 to 0.8 kgh–1.
