The aims of this research are to analyzing the species composition, measure and

frequencies of spiny lobster (Panulirus sp) in Cilacap water. The data are 20 % of

populations as daily fishing catch that was landing from April 30 to May 29, 2006.Identifications result of species composition from 199 species sample of spiny

lobster were green sand lobster (Panulirus homarus), pearl lobster (P. ornatus), bamboo

lobster (P.versicolor), spot/stone lobster ( P. penicullatus). The lobster species

composition were green lobster 66 %, pearl lobster 13 %, bamboo 8 % and spot lobster 3%.

The measures of spiny lobster were weight, total length and carapace length. The

dominant of weight frequency of green sand lobster was 50-100 g interval class (83species), the pearl, bamboo and stone lobsters was 100-150 g interval class. The

dominance interval class of all lobster species was 100 150 g .

The dominance frequency of total length for green sand lobster was 76 95 mmclass interval, pearl lobster 160-176 mm, bamboo 136-155 mm and stone lobster was

116-135 mm. The dominance frequency of total length for all species was 156-175 mm

interval class and dominance frequencies of weight were 36-50 g and 101 125 g.The dominance class interval of Carapace length green sand lobster was 31-35

mm, pearl lobster was 60-65 mm, bamboo and stone lobster was 41 45 mm. Lobstercatch have been influence by fixation of fishing ground, fishing gear construction, fishing

technique and fishing boat. Fisherman conditions as small scale fishery fixingcompositions and measure of spiny lobster focusing the dominances of class interval

frequencies.

Key words : species composition, dominance frequency, measure, spiny lobster.
