| Abstract |
Gastropoda is one of the families of the molluscum phylum found in abundant amounts. Its existence in the mangrove forest ecosystem of Merauke Regency brings potential in developing alternative foodstuffs from the sea in addition to other fishery protein sources such as Fish and Shrimp. The study took place in two mangrove ecosystem locations at Lampu Satu Beach and Payum Beach using the line transect method with purposive sampling placed quadrants successfully identified as many as 8 (eight) gastropod species included in 4 (four) families namely Littorinidae, Potamididae, Neritidae and Ellobiidae. The species with the highest abundance is owned by L. Scabra at 44.03 ind/m2 with a relative density of 87% at Station I, while at station II is owned by species L. Scabra 20.83 ind/m2, T. sulcata 13.4 ind/m2 and C. obstusa 11.3 ind/m2. Furthermore, for Frequency of Attendance at Station I L.scabra at 100% and C. obstusa 67%, at Station II L. scabra and C. obstusa both at 97%. Based on the analysis of the shell length it is known that the species with the longest shell size are owned by the species T. telescopium 7 cm; T. sulcata 6.21 cm and T. palustris 5.29 cm. The edible portion of gastropods can be seen from the weight of the meat to the total weight, so that the species with the highest percentage is known to Nerita sp. 43%, C. angulifera and N. lineata 35%, and L. scabra 34%. |
