Abstract
Yellowfin tuna (Thunnus albacares) formed an average
33.5% of the total tuna catch of Andhra Pradesh, during
the past decade. Fishing grounds for yellowfin tuna
off northern Andhra Pradesh at depths of 200 m and
more are gainfully exploited by the local fishers since
2002 using motorized crafts (theppas) with hooks and
lines and trolls. Since 2006 a few mechanized trawlers
were also converted to long liners for catching tunas
