The aim of study is to analyze Length-Weight Correlation [LWC] and Condition Factor [CF] of wild spiny lobster juvenile Panulirus spp. (Decapoda: Palinuridae) inhabit in Cilacap waters. Juvenile of spiny lobsters are collected by dives and lighted attractor as juvenile trap from August to October 2018. The spiny lobster juvenile from study site is collected and accommodated in stereo foam box containing sea water and aerated. The juvenile is transported to laboratory and kept in 50×70×50 cm glass box containing sea water, aerated and identified. Total of 231 spiny lobster juveniles were collected and identified were found three species, namely P. homarus (213 individuals), P. versicolor (9 individuals) and P, ornatus (11 individuals). Minimum of CLand weight were found 3.2 mm and 0.01 g; and maximum were obtained 21 mm and 0.52 g. The LWC juvenile was found strong relation and were close to 1. The CF Panulirus spp. juvenile was obtained 0.009865 ± 0.00409 and the CF of P. ornatus was the highest value [0.011218 ± 0.00406] than other species. The habitat of Cilacap coastal waters demonstrated more support to the growth of P. ornatus than the growth of P. homarus and P. versicolor.
