Abstract

The Alligator gar, Atractosteus spatula (Lacepède, 1803), is a high-predatory fish native to North America. In 2020, two specimens were captured as a new species in the public waters of Klawing River, Central Java, Indonesia at 7°'19’.27"S 109°20'10"E. Therefore, this study aims to describe the meristic and morphometric features of Atractosteus spatula based on an in-situ observation in the river.

Abstract

This research aimed to know the effect of quail manure on an abundance of Daphnia magna. The research method for D. magna was a Completely Randomized Design (CRD) with four settings, each repeated four times, namely the use of P0 (Control without fertilizer), P1 (Quail manure fertilize 1 g/L), P2 (Quail manure fertilize 3 g/L), P3 (Quail manure fertilize 5 g/L). D. magna was cultured for 15 days in a container with a volume of 3 liters. The updated parameters were abundance of D. magna, mortality of D. magna, and water quality. The results were analyzed using ANOVA analysis. The results showed that the highest abundance was in P2 (3g / L), and the lowest was in P0 (control). Water quality during the research was temperature 21-24°C, pH 7,5-8,4, DO 6,2-7,8 ppm, and ammonia 0-0,25 mg/L.
