Abstract

Depik (Rasbora tawarensis) is one of the endemic species from Laut Tawar Lake, Aceh Tengah District. The objective of this study was to determine the effect of Daphnia magna enriched by vitamin C with the different dosage on the survival rate and growth rate of Depik fry. This research consist of fine treatments and three replication, namely: A (control); B (Daphnia magna enriched by 50 mg/L); C (Daphnia magna enriched by 100 mg/L); D (Daphnia magna enriched by 150 mg/L); and E (Daphnia magna enriched by 200 mg/L).  Fish was fed three times a day with ad-libitum method. The result of ANOVA showed that Daphnia magna enriched by the different dosage of vitamin C gave the effect on the survival rate, length growth rate, weight growth rate and specific growth rate of Depik (P0.05). The optimum value for those parameters were obtained at treatment E, where as the length growth rate was 3.38 cm, weight growth rate was 0.51 g, specific growth rate was 5.49 % and survival rate was 96.67 %.       Ikan depik (Rasbora tawarensis) adalah salah satu ikan endemik dan merupakan spesies penting Indonesia yang hanya didapatkan di Danau Laut Tawar Kabupaten Aceh Tengah. Tujuan penelitian ini untuk manganalisa pengaruh pemberian Daphnia magna yang diperkaya vitamin C dengan dosis berbeda terhadap faktor kelangsungan hidup dan pertumbuhan benih ikan depik. Penelitian ini dilaksanakan di UPT Balai Benih Ikan Lukup Badak Kabupaten Aceh Tengah pada bulai Maret – April 2017. Penelitian ini terdiri dari 5 perlakuan dan 3 ulangan yaitu A (kontrol); B (Daphnia magna diperkaya vit C 50 mg/L); C (Daphnia magna diperkaya vit C 100 mg/L); D (Daphnia magna diperkaya vit C 150 mg/L); dan E (Daphnia magna diperkaya vit C 200 mg/L). Ikan diberi pakan 3 kali sehari secara ad-libitum. Hasil uji ANOVA menunjukkan bahwa Daphnia magna yang diperkaya dengan vitamin C dosis berbeda *berpengaruh nyata terhadap kelangsungan hidup, pertumbuhan panjang mutlak, pertumbuhan bobot mutlak, serta laju pertumbuhan spesifik benih ikan depik (Rasbora tawarensis) (P0,05). Hasil penelitian ini memperlihatkan bahwa nilai tertinggi terdapat pada perlakuan E dengan kelangsungan hidup (96,67 %); pertumbuhan panjang mutlak (3,38 cm); pertumbuhan bobot mutlak (0,51 gr); dan laju pertumbuhan spesifik (5,49 %).

Abstract

Tinfoil barb (Barbonymus schwanenfeldii) is freshwater fish found in Borneo, Java, and Sumatera including in Aceh Province waters. It is known as a native species in Indonesia, locally known as Tengadak or Lampan and this species is popular for consumption due to its taste. Tinfoil barb is targeted species of inland water for fisheries production. In recent years, the fish population has declined because of overexploitation and habitat degradation. Therefore, this study aimed to analyze the effects of temperature on Tinfoil barb (B. schwanenfeldii) eggs incubation using a funnel system. It was conducted at Balai Benih Ikan (BBI) Lukup Badak, Central Aceh Regency. The Completely Randomized Design was used as a statistical analysis method with four treatments and three replications at 221 oC, 251 oC, 281 oC, and 311 oC. Hatching was carried out using a funnel system with 100 grain/liter of eggs density for incubation. The parameters measured were hatching time and rate, egg yolk absorption time, the survival rate of the embryo, larvae abnormality, and water quality. The ANOVA test results showed that temperature significantly affected hatching time and rate, egg yolk absorption time, and larvae abnormality (P0.05). In contrast, the effect was insignificant on the survival rate of an embryo, with P0.05. It is concluded that the optimum temperatures for Tinfoil barb eggs incubation were about 251 oC311 oC. A funnel system was more effective for incubation than the conventional system.Keywords:Tinfoil barbFishIncubationTemperatureFunnel System

Abstract

Global biodiversity, especially fish, has experienced a decline, this occurs as a result of over-exploitation, the presence of introduced fish species and climate change. This condition makes researchers look for solutions to overcome these problems by using cryopreservation techniques. The main purpose of cryopreservation is to store, maintain, and ensure the survival of genetic material, so that using cryopreservation techniques can maintain the viability and function of gamete cells both immunologically, biologically and physiologically. The success of the cryopreservation technique has made this technique widely developed in various species of living organism including fish. This article summarizes and reviews the history of the development of cryopreservation of animal species with specific focus on fish.Keywords:CryopreservationHistoryDepikEndemic species
