Ikan depik ialah ikan yang hanya terdapat di Danau Laut Tawar Aceh Tengah yang sedang dalam pengembangan untuk didomestikasikan. Namun dari hasil beberapa penelitian, pertumbuhan ikan depik tergolong lambat, sehingga perlu ditingkatkan. Salah satu cara untuk mempercepat pertumbuhan ikan depik adalah dengan induksi hormonal, melalui perendaman hormon tiroksin. Tujuan riset ini adalah mengevaluasi performa pertumbuhan dan sintasan ikan depik yang direndam hormon tiroksin dengan perbedaan lama perendaman. Riset ini dilaksanakan di Balai Benih Ikan (BBI) Lukup Badak, Aceh Tengah menggunakan metode eksperimental rancangan acak lengkap (RAL) dengan empat perlakuan dan tiga kali pengulangan. Perlakuan pada riset ini ialah perbedaan lama perendaman hormon tiroksin, yaitu: tanpa perendaman (P-1), 12 jam (P-2), 24 jam (P-3), dan 36 jam (P-4). Sementara dosis hormon tiroksin yang digunakan adalah 0,1 mg L-1. Perendaman dilakukan menggunakan stoples bervolume 16 L untuk 20 ekor benih ikan depik hasil pembenihan berukuran 3,17 ± 0,09 cm. Pemeliharaan benih ikan dilakukan menggunakan styrofoam berukuran 70 cm x 40 cm x 30 cm sesuai dengan perlakuan, selama 40 hari dengan padat penebaran 20 ekor/wadah. Parameter pengamatan yaitu pertumbuhan bobot dan panjang mutlak, laju pertumbuhan spesifik, efisiensi, dan intake pakan, serta sintasan. Data hasil pengamataan dianalisis menggunakan analisis varian dan Duncan. Hasil yang diperoleh memperlihatkan perendaman tiroksin pada benih ikan depik memberikan pertumbuhaan tertinggi pada perlakuan perendaman 24 jam, sementara pertumbuhan terendah terdapat pada perlakuan kontrol (0 jam perendaman). Sehingga dapat disimpulkan bahwa lama perendaman hormon tiroksin terbaik pada ikan depik adalah 24 jam.Depik (Rasbora tawarensis) is an endemic fish in Lake Laut Tawar, Central Aceh currently undergone domestication programs. Results from several domestication studies showed that the growth of depik fish is relatively slow and therefore needs to be stimulated. Hormonal induction, through immersion of the thyroxine hormone could be used to speed up the growth of depik fish. The purpose of this study was to evaluate the growth and survival performance of depik immersed in thyroxine hormone with differences in immersion time. This research was conducted at the Balai Benih Ikan (BBI) Lukup Badak, Central Aceh using an experimental method arranged in a completely randomized design (CRD) with four treatments and three replications. The treatments in this study were different immersion times in 0.1 mg L-1 thyroxine hormone solution set as follows: no immersion-control (P-1), 12 hours (P-2), 24 hours (P-3), and 36 hours (P-4). The immersion method was carried out using transparent plastic jars with a volume of 16 L. Each jar was filled with 20 depik fish fries produced from a hatchery with an average total body length of 3.17 ± 0.09 cm. After submersion, the fish were stocked in styrofoam containers sized 70 cm x 40 cm x 30 cm based on their treatments groups and reared for 40 days. The parameters observed included absolute length growth, absolute weight growth, daily growth rate, amount of feed consumption, feed efficiency, and survival. The data obtained were analyzed using ANOVA test and continued with Duncan’s test. The results showed that thyroxine immersion in depik fish fry gave the highest growth was produced in the treatment of 24-hour immersion, while the lowest growth was found in the control treatment (0-hours immersion). So it can be concluded that the best thyroxine hormone immersion time in depik fish is 24 hours.

Environmental problems due to aquaculture occur along with the increase in aquaculture production. IMTA is one system used as a solution in dealing with environmental problems. The objective of this study was to analyze the growth performance, survival rate, and production of the main commodity (tilapia) and the supporting commodities (Peres, Lemeduk, and Depik) which are applied through the application of integrated multi-trophic aquaculture (IMTA) using floating net cages. This research was conducted at the Lukup Badak Fish Seed Center, Central Aceh from July to August 2020. The experimental design used was a completely randomized design (CRD) with 4 treatments and 3 replications, namely: A (tilapia), B (tilapia and peres), C (tilapia and lemeduk), and D (tilapia and depik). ANOVA test results showed that the IMTA system had a significant effect on absolute length growth, absolute weight growth, specific growth rate (SGR), survival rate, and biomass production of tilapia (P0.05). The results showed that maintenance for 42 days produced the highest value in treatment B with the increase in absolute length growth (4.26cm±0.24); absolute weight growth (5.47g±0.45), specific daily growth rate (2.28%/day±0.13) and the highest tilapia biomass production (480g/0.5m2±19.25). The highest survival rate was found in treatment C (82.42%±2.28). It was concluded that the treatment using the IMTA system was better than without the IMTA system.Keywords:IMTAWater qualityGrowth performanceTrophic interactionBiomass production

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 22±1 oC, 25±1 oC, 28±1 oC, and 31±1 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 25±1 oC–31±1 oC. A funnel system was more effective for incubation than the conventional system.Keywords:Tinfoil barbFishIncubationTemperatureFunnel System

Abstract. Kawan fish (Poropuntius tawarensis) is an endemic fish found in Danau Laut Tawar, Central Aceh, Indonesia. This species has been threatened by ecological partubation, unfrindly fishing practices and pollution. Cryopreservation is one of the ways to maintain the presence of these fish. Cryoprotectant (CP) is a critical material in the cryopreservation and DMSO is a common CP used in cryopreservation. Hence, the aim of the present study was to determine the optimum DMSO concentration for kawan fish sperm. The completely randomized design with 6 treatments and 3 replications were used in this study. The tested treatment was the difference of DMSO concentration, namely; 0, 3%, 6%, 9%; 12%, and 15% DMSO was combined with 5% egg yolk. The ratio of sperm to diluent is 1: 20. The cryotubes containing diluented sperm were evaporated at 5 cm from the surface of liquid nitrogen for 10 min, then stored in a liquid nitrogen container at -1960C for 2 weeks, then thawed and analyzed for the quality. The results showed that fresh sperm of kawan fish had motility of 48.67%, pH 7, milky white, with moderate consistency. The assessment of mass movements shows that the sperm has good quality. The ANOVA test showed that the addition of DMSO in diluents gavee significant effect on sperm motility, fertility and hatchability rates of fish eggs (P 0.05). The highest percentage of sperm motility and fertilization rates of fish eggs were found at concentration of 6%, respectively with the value of 46.67% and 45.67%, respectively. The highest percentage of hatching rate was also found in similar concentration of DMSO with the value of 19.33%. %. The DNA integrity test using the electrophoresis gel method showed that there was damage to DNA fish sperm after freezing, the the lower damage was found at 9% and 12% DMSO. It is concluded that the optimum concentration of DMSO for kawan fish sperm is at 6% of DMSO. Key words: kawan fish (Poropuntius tawarensis), cryopreservation, DMSO, DNA integrity Abstrak. Ikan kawan (Poropuntius tawarensis) merupakan ikan endemik yang terdapat di Danau Laut Tawar, Aceh Tengah, Indonesia. Menurut IUCN (International Union for Conservation of Nature), ikan ini termasuk ikan yang terancam punah oleh sebab kerusakan lingkungan, penangkapan tidak ramah lingkungan dan polusi. Salah satu cara untuk menjaga keberadaan ikan tersebut adalah dengan penerapan metode kriopreservasi sperma. Oleh karena itu, penelitian ini bertujuan untuk menentukan konsentrasi DMSO optimum dan melihat kerusakan DNA yang terjadi pada sperma ikan kawan(Poropontius tawarensis) pasca pembekuan.Metode yang digunakan dalam penelitian ini adalah Rancangan Acak Lengkap (RAL) dengan 6 perlakuan dan 3 ulangan.Perlakuan yang diuji adalah perbedaan konsentrasi DMSO dengan konsentrasi 0; 3%; 6%; 9%; 12% dan 15%.DMSO tersebut dikombinasikan dengan 5% kuning telur. Perbandingan sperma dengan pengencer adalah 1 : 20. Semua cryotube yang berisi sperma dan pengencer diuapkan pada jarak 5 cm dari permukaan nitrogen cair selama 10 menit, selanjutnya, disimpan dalam kontainer nitrogen cair bersuhu -1960C untuk disimpan selama 2 minggu. Hasil penelitian menunjukkan bahwa sperma segar ikan kawan memiliki nilai motilitas sebesar 48,67%, pH 7, berwarna putih susu, dengan konsistensi sedang. Penilaian gerakan massa menujukkan bahwa sperma tersebut berkualitas baik. Hasil uji ANOVA menunjukkan bahwa penambahan DMSO dalam pengencer berpengaruh nyata terhadap motilitas, fertilitas dan daya tetas telur ikan kawan (Poropontius tawarensis) (P0,05) setelah pembekuan. Selanjutnya, uji lanjut Duncan menunjukkan bahwa persentase motilitas sperma dan pembuahan telur ikan kawan tertinggi terdapat pada penambahan DMSO dengan konsentrasi 6%, masing-masing sebesar 46,67% dan 45,67%. Persentase penetasan telur tertinggi juga dijumpai pada perlakuan 6% DMSO, dengan nilai 19,33%. Hasil uji integritas DNA menggunakan metode elektrofresis gel menunjukkan bahwa terdapat kerusakan pada DNA sperma ikan pasca pembekuan, Kerusakan yang terendah terdapat pada konsentrasi DMSO 9% dan 12%. Namun secara umum, disimpulkan bahwa konsentrasi optimum untuk kriopreservasi ikan kawan adalah 6% DMSO.Kata kunci: ikan kawan (Poropuntius tawarensis), kriopreservasi, DMSO, integritas DNA
