Morphology of the Female Gonads of the Long-legged Spiny Lobster
Yusnaini Yusnaini, Indriyani Nur , Muhammad Idris and Farid Yasidi

Background and Objective: Spiny lobster is an economically valuable fishery commodity. For the development of its management, a further study on various biology aspects is necessary. The objective of this research was to study some aspects of long-legged spiny lobster reproduction particularly the gonad development based on morphology and microscopic examination of histological preparations of ovaries and the relationship between body and gonad weight with the aim of contributing to the basic knowledge of reproductive system and introducing this species into aquaculture. Materials and Methods: Lobsters (Panulirus longipes) were caught in South East Sulawesi, Indonesia coastal water. The lobsters were sampled to check for gonad development and maturity stages. The other lobsters were continued to be maintained under culture. Samples were dissected and characterized and the gonads were used for morphology and histological studies. Gonad developmental stages were classified according to the difference and developmental progress of gonad was observed. Photomicrographs of all stages were made and observed. Diameter sizes of mostly ova were measured in 3 separated parts: Anterior, middle and posterior. This was to determine whether this specie is total or partial spawner. Results: Gonadosomatic index (GSI) were also counted to determine the maturity of lobster sample. Maturity level 1 had an average GSI of 0.2%, while lobsters with a maturity level 2 and 3 had GSI of 2.97 and 4.19%, respectively. Gonad pigmentation was not specific between the maturity levels of gonads 2 and 3. Conclusion: Results showed that the ovaries contained gonads in different stages of development in the same ovary, indicating long-legged spiny lobster tend to spawn in different groups (partial spawners).
