Abstract

Tawang Bay and Karranggongso Bay have been well-known as settlement areas for lobster larvae in East Java Indonesia,19 which may suggest that the location are suitable environments including diet availability for lobster larvae. Therefore, the study aimed to 20 investigate the abundance and diversity of plankton in the both locations to discover potential live diets for lobster larvae. Plankton 21 samples were collected in both locations using a plankton net at four different depths: 0.3m, 2.5m, m, and 20m with three replicates.22 The result revealed that 17 plankton species were identified from the 0.30m depth, 13 species at a depth of 2.5m, 11 species at a depth of 23 5m, and 13 species at 20m at karanggongso Bay. While, 17 plankton species were discovered on the surface of Tawang Bay waters: 11 24 species at a 2.5m, 12 species at 5m, and 12 species at 20m. The diversity index and uniformity indices of plankton in both locations 25 were considered at a moderate. While there were no dominant species at both locations, indicated by the dominance index values ranged 26 from 0.13-0.30. Among the identified plankton species, Oithona sp., and Acartia sp. are considered potential live feed for lobster larvae,27 and thus should be further studied.
