The mortality of tinfoil barb during transportation is relatively high due to the oxygen consumption rate and excretion of these fishes. Therefore, the use of an appropriate anesthetic drug becomes one of the solutions for solving this transportation problem of tinfoil barb. One of the natural anesthetic drugs with potential to be studied is Chromolaena odorata leaves. The purpose of this study is to evaluate the effectiveness of anesthetic compounds from Chromolaena odorata leaves in the closed transportation of tinfoil barb. The experimental design used was a non-factorial completely randomized design that consisted of four treatments and three replications,then followed by a Tukey test to see if there was a significant difference. The experimental treatments were A (0 ml/L of leaves filtrate), B (80 ml/L of leaves filtrate), C (90 ml/L of leaves filtrate), and D (100 ml/L of leaves filtrate). The observed parameters were fish behavior towards unconscious condition, onset time, immotilization time, survival rate, and water quality. The results showed that the shortest onset time was obtained from treatment D (100 ml/L leaves filtrate), namely 58 minutes towards unconscious condition, then the longest immotilization time was also shown by treatment D, which was 371 minutes. The highest survival rates were also shown by treatment D which were 94,33% during transportation and 76,33% during culture. The water quality parameters during the experiment were in an optimum condition of tinfoil barb. Keywords:AnestheticChromolaenaodorataTransportationTinfoil barb

Abstract This study aims to determine the effect of giving Morinda fruit distilation for handling Argulus on Carrasius auratus auratus. The research method that used was experimentally with Completely Randomized Design (CRD) with five treatments and four replications. The used treatment are : medium with Morinda distilation mixed 0% (A), medium with Morinda distilation mixed 2,5% (B), medium with Morinda distilation mixed 3% (C), medium with Morinda distilation mixed 3,5% (D), medium with Morinda distilation mixed 4% (E). The results showed that giving Morinda fruit distillation on Carrasius auratus auratus which have Argulus infest significantly different (p <0.05) with the best treatment in D with six releasing Argulus and that fish can survive within 15 minutes dipping. The lowest treatment result in A (control) with nothing releasing Argulus. Water quality parameters are supporting this research. Supporting parameters measured during the study is the water temperature ranges 27° C, pH 7,5-8,5, DO 8 mg/L to 5 mg/L, and salinity from 0 to 3 ppt. Water quality parameter are still within tolerance limit for Carrasius auratus auratus

Ikan diberi perlakuan dengan konsentrasi deterjen yang berbeda, perlakuan yang diberikan yaitu: perlakuan A (Kontrol), B (deterjen 3 %), C (Konsentrasi deterjen 6 %) dan D (Konsentrasi deterjen 9 %). Pengambilan data dilakukan setiap 7 hari sekali. Adapun rancangan yang digunakan pada penelitian ini adalah Rancangan Acak Lengkap (RAL) dengan 4 perlakuan 3 ulangan dan dilanjutkan dengan Uji Beda Nyata Jujur jika terdapat perbedaan. Parameter yang diamati adalah parameter pada laju pertumbuhan, kelangsungan hidup, histologi insang dan efisiensi pakan serta parameter kualitas air (suhu dan pH). Hasil penelitian menunjukkan bahwa ikan nila yang diberi perlakuan konsentrasi deterjen 3 %, 6 %, 9 % berpengaruh terhadap pertumbuhan dan kelangsungan hidup. Perlakuan kontrol menghasilkan nilai, laju pertumbuhan dan efisiensi paling baik, yaitu masing-masing sebesar 2,84 gram, 97,36 %, sedangkan untuk kelangsungan hidup menunjukkan hasil yang terbaik pada perlakuan konsentrasi deterjen 3 % yaitu 100 %. Parameter kualitas air selama penelitian yang diukur antara lain adalah suhu air dengan kisaran 26,6-28,1 ᵒC, dan pH 7,1-7,8. This study aimed to know the effect of surfactant on growth, survival rate and gill histology of tilapia fingerling.

Abstract Dissolved oxygen is the parameters key of water quality. Low level of dissolved oxygen can affect the function and slow growth, can even cause death to fish in hypoxia condition. The aims of this experiment were to determine the effect of population density of Daphnia spp. of dissolved oxygen concentration and the correlation between dissolved oxygen concentration with color scoring of Daphnia spp. This method was experimental with Completely Randomized Design as experiment design with 6 treatments and 4 replications. The treatment that was given were the differences of Daphnia spp. density that consisted of treatment A (50 individu/200 ml), treatment B (250 individu/200 ml), treatment C (450 individu/200 ml), treatment D (650 individu/200 ml), treatment E (850 individu/200 ml), and treatment F (1050 individu/200 ml). The results showed that the difference of Daphnia spp. density showed highly significant effect of dissolved oxygen concentration of treatment medium (p<0,01). In addition, this experiment also showed that the dissolved oxygen concentration in treatment medium showed negative correlation with color score of Daphnia spp.
