ABSTRACT

The lobster life phase is eggs, phyllosoma, puerulus, juvenile, and young lobster. The metamorphose coincides with its inshore movement and ends up into adult lobsters that inhabit the continental shelf area. The wild population of lobsters is determined by the survival rate of the puerulus. Fish larvae aggregating devices have been given significant results as a shelter or refuge area for several fish species. This device is then referred to as the Larva Shelter Device (LSD). The question is whether there is a preference for lobster larvae on attractor or shelter materials. The innovation of shelter materials in LSD is cement sack paper, waring nets and gunny sacks. The number of lobster larvae in different materials was analyzed. The research was carried out in February-May 2021 at Mutiara Beach Karanggongso of Prigi Bay, Tasikmadu, Watulimo, Trenggalek, East Java, Indonesia. The identification method of puerulus species is based on taxonomic and morphological characteristics. Initial identification is done by recording and photographing species, then adjusting to the experiences of fishermen compared to Jones and Dao 2010. The study found there were 3 types of puerulus species collected including puerulus of Panulirus ornatus, P. homarus, and P. versicolor. The highest species presentation in the three shelter materials was P. homarus. The data indicate that different shelter materials had no significant effect on the species composition of the spiny lobster puerulus.
