Effect of addition of red spinach leaf extract (Amaranthus tricolor L.) in feed against the level of color brightness of sword platy fish (Xiphophorus helleri)

Color is important factor ornamental fish, especially sword platy fish, because can affect selling value. One factor influences color brightness is carotenoids. Carotenoids cannot synthesized by fish's body so must be supplied through feed provided. Red spinach is a natural ingredient that contains carotenoids. Aim of research was to determine effect of adding red spinach leaf extract to artificial feed to increase color brightness, growth and survival of Xiphophorus helleri. Research method used a completely randomized design with 4 treatments and 4 repetitions. Concentrations of red spinach leaf extract are 0%, 3%, 6% and 9%. Parameters observed were color brightness, absolute weight, absolute length, survival rate and water quality. Results showed that addition of red spinach leaf extract had a significant effect (P0.05) on growth, weight, length and survival rate. Highest increase in color brightness and absolute weight growth was obtained in 9% treatment with an average color brightness score of 6.66, an absolute weight of 0.36 g. Highest absolute length growth occurred treatments C (6%) and D (9%) at 0.41 cm and highest survival rate was obtained treatments A, B and C with a survival percentage of 88%

The growth performance of common carp (Cyprinus carpio) co-cultured with different vegetable plants in aquaponics system

A 28-days trial was conducted in an aquaponics culture system to determine the effect of the different vegetable plants application on the growth performance and survival rate of common carp (Cyprinus carpio). Common carp seeds were obtained from local fish farmers in Aceh Besar District. A total of 360 common carp fingerlings (size 3-5 cm) were used and placed in 12 containers with the capacity of 80 L each. The study used four treatments, namely A (control), B Kale (Ipomoea aquatica), C Lettuce (Lactuca sativa), and D Pakcoy (Brassica rapa subsp. chinensis), with three replications for each treatment. The result showed that different vegetable plants' applications significantly affected (P 0.05) the absolute weight gain, absolute length gain, and survival rate of common carp fingerlings. The highest value obtained was in treatment B (Ipomoea aquatic) with an absolute weight gain of 3.93 ± 0.28 g, absolute length gain of 3.81±0.21 cm, and survival rate of 100±0.0%, while the lowest was in treatment A (control) with an absolute weight gain of 1.21±0.76 g, absolute length gain of 1.70±0.10 cm and survival rate of 91±0.86%.

A nesting ability of male siamese fighting fish (Betta sple ndens) under different level of turbidity derived from palm oil mill effluent

Contamination of Palm Oil Mill Effluent (POME) into water bodies potentially disrupting the visualization and affects behaviourial changes such nesting ability of male Siamese Fighting Fish (Betta splendens). The study examined the effects of turbidity due to POME contamination toward nest area as one of the indicators for the reproductive behavior of the betta splendens. The research used Completely randomized Design with different level of turbidity: <1 NTU (control), 20 NTU (treatmen A), 40 NTU (tretment B), 60 NTU (Treatment C). Preference tests were carried out in a 6-L aquarium (20x20x20 cm3). Nest area was measured each hour for 8 hours. Nest area was captured using camera and measured with imageJ. Result showed there was no significant difference in nest area of Betta splendens in different level of turbidity. The range of nest area in sequence until the end of exposure were 0-0.8 cm2, 0.7-2.5 cm2, 4.6-6.7 cm2, 4.5-7.2 cm2, 7.6-8.7 cm2, 9.4-11.11 cm2, 9.7-12.5 cm2, dan 11.6-14.14 cm2. Turbidity due to POME collected from the last pond with low pollutant contamination has no impact on nesting ability of betta fish. Nest building behavior is often correlated with hormone concentrations due to pollutant contamination with a certain consentration of pollutant

Turbidity effect derived from palm oil mill effluent altered predation period of siamese fighting fish (Betta splendens, Regan 1910)

Contamination of palm oil mill effluent (POME) into water bodies potentially increases turbidity, resulting in disrupting aquatic organisms behaviour, including predation period. However, the effect of increased turbidity due to POME contamination toward the fish predation is still unexplored. Siamese fighting fish (Betta splendens) is one of the ideal test fish to investigate this effect. This study aims to analyze the effect of increased turbidity due to POME contamination toward the fish predation period of Siamese fighting  fish. The research design was completely randomized with six treatments (0, 20, 40, 60, 80 and 100 NTU) followed by five repetitions for each treatment. The experimental data parameters include the predation rate of Siamese fighting  fish during foraging activity, which was calculated from the percentage of the number of mosquito larvae consumed per 2 min during 15 min. The significance level of predation between treatments in each observation time period was analyzed using a one-way Analysis of Variance (ANOVA) with the confidence interval set at the 95% level.  The results showed that at a turbidity level of 100 NTU, the predation period of Siamese fighting  fish had been altered. In the period of 0-2 min, the predation rate decreased significantly. Meanwhile, the predation rate increased significantly during the period of 2-4 and 8-10 min. This finding should be considered  to support POME remediation management, especially turbidity parameters. Keywords: POME Feeding period Foraging area Turbidit
