Abstract

The purpose of the research was to give information condition and potention of mud crab. This research used survey method which are a). observation, b). direct interview c). in situ treatment and d). sampling.  Research location at Sungai Musang Village, Aluh-Aluh, Banjar Regency, South Kalimantan Province. Parameters observe were mud crab species, water quality (water temperature, salinity, water pH, NO2-N, NO3-N, NH3-N, DO, and transfarance), and biology (plankton dan mud crab larvae). The results founded that 3 mud crab species 1). Scylla serrata 2). S. transquebarica and  3) S. oceanica. The range of water temperature was (30-340C), Salinity (0-1%o), water pH (7,80-8), NO2-N (0,36 mg/L), NO3-N (2,01 mg/L), NH3-N (0,46-2,5 mg/L), DO (1,65-4,20 ppm), transparance (32 cm), diversity index of phytoplankton (0,89), and  zooplankton (1,58).  Ecology and biology, showed that water quality was suitable to mud crab culture. Mud crab larvae was trap zoae and megalopa stadia with density of 20 ind/L. Little number of mud crab trapped, was assumed due todisfunction condition of  mangrove forest.

Abstract

The purpose of the research was to evaluate the response of the population abundance of Moina macrocopa to the addition of Spirulina platensis flour into mass culture media. In this research, each added 0 mg/day (control), 500 mg/day, 750 mg/day of  Spirulina platensis, as well as the treatments being tested. As a control, dry manure was used. This research was conducted at the Wet Laboratory (wet lab.) Faculty of Fisheries and Marine, Lambung Mangkurat University Banjarbaru. As an experimental container (experimental unit) were 12 aquariums measuring 45 x 25 x 30 cm. In this research, an experimental design was applied, namely Completely Randomized Design (CRD). Statistical testing using Test F or ANOVA with a significant level of 5% and 1%. The further statistical analysis used for the significant treatment calculated F value was Duncan's Test (DMRT). The results showed that at the peak of the abundance of Moina macrocopa (day 21), the highest population was in treatment B = 708 ind/liter, followed by treatment C=535.33 ind and treatment A=70.66 ind/liter. The results of statistical tests (ANOVA) showed that there was no significant difference (F < Ftable 0.05) in the abundance of Moina macrocopa in the three mass culture media added with Spirulina platensis flour.
