The condition and nutrient content of introduced freshwater shrimp Macrobrachium lanchesteri at two urban small ponds, Cibinong, West Java, Indonesia

Abstract

'Situ' Lotus and 'Situ' Cibuntu are small ponds located in urban areas at Cibinong Science Center-Botanical Garden, National Research and Innovation Agency, Indonesia. This study was conducted to determine the development of the introduced freshwater shrimp Macrobrachium lanchesteri in that ponds. Observations were carried out in January and February 2019. There are four sampling points in each pond. The number of shrimp obtained at Lotus Pond is more than Cibuntu Pond. The average total length and weight of shrimp obtained at Lotus Pond during the first observation were 1.61 - 2.55 cm and 0.07 - 0.20 gram, while the second was 1.67 - 2.27 cm and 0.11 - 0.31 gram. Meanwhile, M. lanchesteri obtained at Cibuntu Pond in the first observation had an average total length of 2.20 - 2.63 cm and weight 0.16 - 0.20 gram; and when the second sampling was 2.27 - 3.00 cm and 0.16 - 0.34 gram. Proximate analysis of shrimp from Cibuntu Pond showed that this shrimp's protein, fat, ash, crude fiber, and carbohydrate content were 58.68%; 10.70%; 15.31%; 7.70%, and 7.61%, respectively. The water quality observed in both ponds is still good and can support the shrimp's life. Utilization of this shrimp as an alternative source of protein can be done if pond water quality is always maintained in the future.
