Hubungan Panjang Berat dan Faktor Kondisi Lobster (Panulirus SP.) di Perairan Pantai Simeulue

The purpose of this research was to know the long weight relation, condition factor and sex-ratio lobster located in the east of Simeulue beach. This research has been done on February 2016 in floating fish cages, the trade collector located at the bay Sinabang, East Simeulue regency is the owner of the floating fish cages. The method of this research was a survey method. Lobster sample was taken 30% of the total lobster captured. It was carried out as many six times as interval five days. The results of this work were found two type of the lobsters which includes Paniluirus penicillatus and Panulirus versicolor composition with 53 and 47%. Based on counting of a long weight relation of Panulirus penicillatus found an equivalence W= 0,00372L 2,571 and Panulirus versicolor with equivalence W= 0,003276 2,609, the value b indicates both type of the lobsters has negative allomatrict growth nature. the average body weight relative value (Wr) and condition factor (K) both type of those lobsters, Panulirus penicillatus value Wr= 100,76 ±12,58 and value K= 2,25 ±0,35, whereas, the Panulirus versicolor value Wr= 101,59 ±16,41 and K= 2,15 ±0,42. Body weight relative of both type of those lobsters over 100 grams indicates that the east Simeulue beach still support for the lobster growth. Condition factor value shows both type of those lobster has the same scale. Based on the survey was found that sex-ratio of Panulirus penicillatus 1:1,04 and Panulirus versicolor 1,17:1. This case showed that the sex-ratio of both these lobsters still in the same ratio
