Abstract

Penelitian ini bertujuan untuk mengetahui jenis, intensitas dan prevalensi ektoparasit yang menyerang Udang Pisang (Penaeus sp.) yang dibudidayakan di tambak Kabupaten Aceh Barat. Penelitian ini dilaksanakan pada bulan Mei sampai dengan Juli 2018. Metode yang digunakan pada penelitian ini adalah metode survey, dimana sampel Udang Pisang didapatkan dari tambak budidaya Kabupaten Aceh Barat. Selanjutnya dilakukan pengamatan ektoparasit pada Laboratorium MIPA Terpadu Universitas Teuku Umar. Hasil penelitian menunjukkan bahwa ditemukan tiga jenis ektoparasit pada sampel Udang Pisang selama penelitian yaitu Vorticella sp., Epistylis sp. dan Zoothamnium sp. Prevalensi untuk masing-masing ektoparasit adalah Zoothamnium sp. sebesar 75%, Vorticella sp. 65% dan Epistylissebanyak 50%. Intensitas ektoparasit untuk masing-masing jenis ektoparasit yang ditemukan adalah Zoothamnium sp. sebanyak 9.60ind/ekor,Vorticella sp. sebanyak 4.38ind/ekor dan Epistylissebanyak 6.80 ind/ekor. Parameter kualitas air selama penelitian adalah suhu 35.7oC, DO 3.98 mg/L, salinitas 23.2 ppt dan pH 7.

Abstract

The research was conducted on January 2011 for fourteen days in Krueng Cut River Aceh Besar District. The objective of this study was to determine the effective depth of oyster spats attachment. It used Completely Randomized Design (CRD) with 4 treatment and 3 replication for each treatment and used asbestor as the collector. The collectors depth for A, B, C and D treathment were 30 cm, 60 cm, 90 cm, and 120 cm respectively that measured from the water substrate. Data was analysed by MANOVA (Multivariate Analysis of Variance) used SPSS 17.0. The result showed that the averages of oyster spats attatchment were 86, 98, 35 and 6, respectively. There is tendency that depth collector could affect oyster spats attatchment.

Abstract

This study aimed to examine the effect of application of different stocking densities in  budikdamber system on the survival rate and growth of silver catfish (Pangasius djambal). The non-factorial Complete Randomized Design (RAL) used in this study consisted of four treatments and three tests. The treatments studied were the application of a stocking density of 5 fishes/container (P1), 10 fishes/container (P2), 15 fishes/container (P3), and  20 fishes/container (P4). The silver catfish used in this study was 6-8 cm in size. The maintenance period of silver catfish in this study was in 40 days. The research parameters that measured in this study were survival rate, absolute weight growth, absolute length growth, specific growth rate and water quality. The results of analysis of variance (ANOVA) showed that different stocking densities on rearing media with the “Budikdamber” system had no significant effect for survival rate, absolute weight growth and specific growth rate of silver catfish (Pangasius djambal), but had a significant effect on absolute length of silver catfish (Pangasius djambal). The best stocking density to increase the absolute length growth of silver catfish is 15 fishes / container (P3) in number 7.36 cm.
