The treatments given consisted of treatment A (control, without adding FRWM), treatment B (adding FRWM 10%), treatment C (adding FRWM 20%), treatment D (adding FRWM 30%) and treatment E (adding FRWM 40%). The study was conducted from July to October 2019 at the Aquaculture Laboratory and Hatchery in Ciparanje of the Faculty of Fisheries and Marine Sciences, Universitas Padjadjaran. The parameters observed include the breaking rate test, sinking rate test, durability test, and stability test. Results showed that the use of FRWM given significant difference (p&lt;0.05) for breaking rate and stability value. However, result showed that the sinking rate and durability value generally did not show significant difference (p&gt;0.05). The FRWM can be used up to a concentration of 30% which gives effect to the sinking rate of the fish pellet which is similar to the control fish pellet namely 0.38 cm/s while the concentration of the meal of the FRWM gives the closest value of breaking rate and stability control as much as treatment B (adding FRWM 10%) with a break rate for 19.93 hours and stability in water for 10 minutes by 91.66%, 30 minutes by 87.60%, and for 60 minutes by 75.26%. The different adding concerntration of FRWM gives effect to the quality of fish pellet while more than 10% can decrease its quality. The difference were show in all treatment in some parameters observed.</p> Meri Alex Sandra, Yuli Andriani, Kiki Haetami, Walim Lili, Irfan Zidni, Muhammad Fatah Wiyatna ##submission.copyrightStatement## http://journalajfar.com/index.php/AJFAR/article/view/30074 Mon, 06 Jan 2020 00:00:00 +0000 A Comparison between Chicken Viscera and Housefly Maggot Cultured from this By-products for Nile Tilapia Diets: Growth Performance, Feed Utilization and Whole Body Composition http://journalajfar.com/index.php/AJFAR/article/view/30075 <p><strong>Aims:</strong> The feeding trials were conducted to compare the effects of partial fishmeal replacement by two different animal protein sources on growth performance, feed utilization efficiency and body composition of juvenile Nile tilapia.</p> <p><strong>Place and Duration of Study: </strong>The study was carried out at the Aquaculture Research Center, Department of Zoology, Faculty of Sciences and Technics, University of Abomey-Calavi for a period of 84 days.</p> <p><strong>Methodology:</strong> Three isonitrogenous and isoenergetic diets were formulated containing fishmeal (CD), chicken viscera meal (CVM) and housefly maggot meal (HMM), as partial fishmeal replacement. Commercial diet Skretting (SK) was used as reference diet. All male <em>Oreochromis niloticus</em> with an average initial body weight of 8.65 g were fed thrice a day to apparent satiation. Each treatment was randomly attributed to three replicates.</p> <p><strong>Results:</strong> Fish fed all experimental diets showed no effects (<em>P&gt;.05</em>) on survival rate (91.33-96.00 %), condition factor (1.85-1.9), protein efficient ratio (2.05-2.37) and feed conversion ratio (1.21-1.40), although higher values were observed with control diets. Final mean weight and daily weight gain of fish fed HMM diet (88.31 g&nbsp;; 0.95 g. days<sup>-1</sup>) were not significantly different from those fed control diets C (88.54 g; 0.95 g/j) and Sk (87.59 g; 0.94 g/j) respectively. Growth performances significantly decreased (<em>P&lt;.05</em>) in CVM group (75.09 g; 0.75 ± g/j). Whole-body protein contents were similar in all groups, whereas lipid content was highest in those fed CVM.</p> <p><strong>Conclusion:</strong> The results indicated that 200 g fishmeal per kilo diet can be successfully replaced with 250 g.Kg<sup>-1</sup> of HMM without adverse effect on growth and feed utilization whereas CVM inclusion did not perform also well.&nbsp;</p> Cayen S.

This research uses a phytoremediation method using floating water plants. The purpose of this research was to obtain water plants that have better absorption ability as phytoremediation agents for tofu liquid waste between Lemna and Kiapu aquatic plants. This research was conducted at the Laboratory of Aquatic Resources, Faculty of Fisheries and Marine Sciences, Padjadjaran University from March to September 2019. The method used in this research was an experimental method with a Completely Randomized Design (CRD) consisting of three treatments and five replications. Tofu liquid waste samples were obtained from the Tofu Factory in the Cibuntu Tofu Industry Center. Physical and chemical parameters observed include temperature, acidity, dissolved oxygen, BOD<sub>5</sub>, nitrate, and phosphate. The results showed that the Kiapu had better nitrate and phosphate absorption ability than Lemna and the combination treatments for 15 days of observation. The result showed that the decrease in nitrate concentration was 10.12-62.24% and the decrease in phosphate concentration was 6.67-54.23%. Kiapu can be recommended as phytoremediation agents for tofu liquid waste to remediate high organic matter before being discharged directly into water bodies.</p> Qulsum C.
