The fish samples used is a goldfish measuring 3-4 cm. The purpose of this study was to determine the effect of filter material from fibers, rice straw and bagasse as a water filter on the maintenance of a goldfish. This research used experimental method with a completely randomized design (CRD) non factorial with four treatments and three replications. Added greatest long fibers present in the filter material is 1.14 cm. The weight gain fibers contained in the filter material is 1.29 grams and the smallest in the control treatment that is 0.42 grams. Value range of water quality parameters at the time of the study ranged from 25.7 to 29.7 ° C as temperature, pH ranges from 7.1 to 7.6, DO ranged from 3.6 to 5.8 mg / L, turbidity ranges from 1.14 to 22 , 15 and ammonia ranged from 0.022 to 2.056.

Abstract

Banyaknya industri yang berkembang saat ini menyebabkan meningkatnya kadar logam berat seperti merkuri dalam perairan. Penelitian ini bertujuan untuk mengetahui kerusakan struktur jaringan lambung ikan kakap putih (L. calcarifer) yang dipaparkan pada [Hg (NO3)2] dengan konsentrasi yang berbeda. Dalam penelitian ini, ikan dipaparkan dengan konsentrasi 3,16 x 10-2 ppm, 9,99 x 10-2 ppm, 3,16 x 10-1 ppm dan 9,97 x 10-1 ppm. Total ikan yang digunakan untuk histologi adalah 15 ekor. Hasil penelitian menunjukkan bahwa semakin tinggi konsentrasi [Hg (NO3)2] maka kerusakan pada jaringan lambung ikan juga akan meningkat dan mempercepat waktu kematian ikan. Kerusakan yang terjadi yaitu Hipertropi pada sel mukosa lambung, hancurnya villi, terdapatnya ruang antar lapisan otot dan villi serta menipisnya lapisan villi pada konsentrasi [Hg (NO3)2] yang lebih tinggi. Many industries today lead to increased levels of heavy metals such as mercury in water. This research aims to determine the effect of different concentrations of [Hg (NO3) 2] to Asean Sea Bass (L. calcarifer): Gill Histology. In this study, this fishes was treated with 3,16 x 10-2 ppm, 9,99 x 10-2 ppm, 3,16 x 10-1 ppm, and 9,97 x 10-1 ppm. Total fishes used for histological study was 15 fishes. Results of this research showed that increasing the consentrations of the [Hg(NO3)2] will also increase the damage on the stomach structure and fasten the mortality time of the fish. Damage that occurs is hypertrophy aand hyperplacia on epitel cells, , fuse of secundary lamellae and haemorhage on gill that were exposed to high consentration of [Hg(NO3)2].

Abstract

With this study, ascorbic acid and erythorbic acid were used for the first time to prevent melanosis in shrimp. Three shrimp species (Aristaeomorpha foliacea, Plesionika edwardsi and Melicertus hathor) were used. It was determined that melanosis scores were higher in the control groups. Combination of ascorbic acid and erythorbic acid with metabisulphite was found to be more effective in inhibiting of melanosis than the application alone. No significant differences were found between the groups in terms of TVB-N values. The TMA-N value of the control group was significantly higher than those of application groups. Ascorbic acid, Erythorbic acid and their combinations with sodium metabisulphite were found effective on inhibition of melanosis and quality changes in three shrimp species.Keywords: reducing agents; ascorbic acid; erythorbic acid; melanosis; quality; shrimp

Tujuan penelitian ini adalah untuk mengetahui pengaruh penggunaan berbagai bahan untuk fermentasi dedak (ampas tahu, ampas kelapa dan ragi) terhadap laju pertumbuhan dan kelangsungan hidup ikan patin (Pangasius pangasius). Penelitian ini dilaksanakan pada tanggal 10 Mei - 09 Juni 2014  yang berlokasi di Laboratorium Hatchery dan Teknologi Budidaya Perairan Program Studi Budidaya Perairan. Hasil penelitian menunjukkan bahwa penggunaan dedak yang difermentasi dengan bahan yang berbeda (ampas tahu, ampas kelapa dan ragi) sebagai pakan tambahan berpengaruh terhadap pertumbuhan ikan patin. Pertambahan panjang dan bobot tertinggi pada perlakuan B yaitu pemberian pakan pelet dan pakan dedak halus yang difermentasikan dengan ampas tahu dengan nilai rata-rata 0,525 cm dan 0,657 gram. Kelangsungan hidup 100% dan konversi pakan yang terbaik terdapat pada perlakuan B yaitu sebesar 4,333 gram. Parameter kualitas air berada pada kisaran yang baik untuk pertumbuhan benih ikan patin. Analisis statistik dengan uji F di peroleh bahwa penggunaan dedak yang difermentasikan dengan bahan yang berbeda sebagai pakan tambahan tidak berbeda nyata terhadap kelangsungan hidup benih ikan patin (Pangasius pangasius) dengan nilai Fhitung ( 0 ) <  Ftabel (7,59) dan berbeda sangat nyata terhadap pertambahan panjang tubuh benih ikan patin (Pangasius pangasius) dengan nilai Fhitung (147) > Ftabel (7,59) serta berbeda sangat nyata terhadap pertambahan bobot dengan nilai Fhitung (56,500) > Ftabel (7,59)  Selanjutnya berbeda sangat nyata terhadap konversi pakan dengan nilai Fhitung (15,081)  > Ftabel (5,99).The aims of this study is to determine the effect of the application of various materials for fermented bran (pulp, coconut pulp and yeast) on the growth rate and survival of catfish (Pangasius pangasius). This study was conducted on 10 May, 10 to June, 9 2014 at the Laboratory of Hatchery and Aquaculture Technology, Malikussaleh University. The results showed that the application of the fermented bran with different materials (pulp, coconut pulp and yeast) as an additional food was affected the growth of catfish. The highest length and weight was found in the treatment numbers B that was applying  pellets and feed fine bran fermented with the pulp out with the average value  0.525 cm and 0.657 grams. Meanwhile, 100% survival and the best feed conversion contained found in the treatment numbers B which was equal to 4.333 grams. Water quality parameters were within the optimum range for the catfish growth. Statistical analysis by F test  resulted  that the application  of fermented bran with different materials as an feed supplement was not significantly different to the survival of the catfish (Pangasius pangasius) fingerling with the value of F (0) <F table (7.59). The Highly significant to the length of the catfish (Pangasius pangasius) fingerling also found with the value of F (147)> F (7,59) as well as the highly significant to the weight with the value of F (56,500)> F (7,59). Furthermore, highly significant on feed conversion between treatments with the value of F (15,081)> F (5.99).

Abstract

The purpose of this study was to determine the optimum addition of calcium during the adaptation period of white shrimp seed in low salinity media, so the physiological conditions of shrimp still support maximally survival and growth. The research was carried out by using the Completely Randomized Design, i.e., the addition of calcium in freshwater for decreasing water salinity from 20 g L-1 to 0.5 g L-1 as much as 150, 200, 250, 300, and 350 mg L-1, respectively. The freshwater used in the salinity reduction process was based on previous research that included sodium and potassium additions of 75 mg L-1 and 50 mg L-1, respectively. The test animal was a white shrimp stadium PL15 that had been acclimated for 5 days to a medium salinity of 20 g L-1.  The results of this study showed that the addition of 300 mg L-1- calcium in freshwater during the adaptation for 96 hours significantly accelerate the achievement of molting time (1360 minutes), suppress the stress levels and metabolism rate (body fluid glucose of 169.80 mg L-1 and oxygen consumption level of 0.95 mg O2 g-1 h-1), and produce the highest survival rate of white shrimp seed (99%).Keywords: adaptation, calcium, low salinity, physiology, white shrimp
