ABSTRACT
Informalion about catch co~npostilion,catch per unit effort {CPIlE), let~gthand weight of fish
and localion of fishing ground of lemuru ( Sardinella lelrruru Bleeker, 1853) schools are quite
important for ihc succeed of purse seine fishing operation without fish aggegating device.

(Rastreliger spp.) and ternbang (SurdineElafimhriata).
Two years (1996-1998) monthly catch data were used for evaluating CPUE of purse seine
fisheries landing in Muncar fish landing place. The highest CPUE occurred in October as
high as 3,033 kglvessel-operating-day, and the lowest was 304 kdvessel-operatingday in
March.
The lemuru hi@est percentage in the catch composition was more then 80% from August to
February, and the lowest percentage was less than 20% from March to May fishing season.
The smallest lemuru fish fork length(FL) = 6 cm, caught during August to September and the
biggest lemum fish FL>?O cm caught in May. Regression analysis of 620 lemuru fish
samples gave the length-weight relationship as : W = 0.0075 F L ~ ( ~ % . 9 135).
The relation between lemuru fish total length (TL) and fork length (FL) is mentioned as :
TL.4.1508 c1.1139 FL ( ~ ~ = 0 . 9 5 0 7 ) .
The highest lemuru fish FL(19-20 cm) was caught during transition I (March to May) in DPB : Java shore fishing ground, DP-C : southern fishing ground and DP-D : Bali shore fishing
ground.
The smallest lemuru fish FI.(8-10 cm) was caught during southeast monsoon in DP-A :
northern fishing ground.
