Abstract

The research conducted over approximately 60 days at Tarus River, Mata Air Village, Kupang Regency aimed to assess the variety and abundance of eel fish, a high-value commodity in the international market. The study focused on three stations along the river, where the density of eel fish was observed: station 1 (8 individuals), station 2 (5 individuals), and station 3 (2 individuals). Using digital scales, researchers measured the total weight of the caught fish, alongside noting the types of eel fish obtained. The findings, analyzed descriptively and presented through tables and figures, revealed the prevalence of eel fish type A. marmorata during the research period, primarily in the yellow eel and elver phases with varying sizes. Morphometric measurements indicated that Anguilla marmorata specimens typically ranged in total length (35-47 cm), dorsal length (20-30 cm), anal length (15-25 cm), head diameter (5-7 cm), body diameter (7-9 cm), and total weight (170-181 grams). Additionally, water quality assessments at the research site indicated temperatures ranging from 20-27oC, with a pH of 7.5. Keywords: Identification, eel fish (Anguilla marmorata).

Abstract

This research aims to determine the effect of extracts from frangipani flowers under anesthesia during dry transportation on the growth of milkfish and their survival. In the research, fish measuring 4-6 cm and weighing 4-5g were used. The test fish were fasted for 3 days to reduce metabolic activity before being transported. Before packing, a treatment solution is made according to the concentration, namely 4 mg/L, 6 mg/L, and 8 mg/L. Test fish that are placed in the treatment solution are observed for the time required during the fermentation process. Fish that have been knocked out are placed in a transportation container in the form of low-temperature sawdust and lined with gauze and ice. The test fish were then transported for 12 hours and the fish were placed back in a container containing clean aura. The number of fish that died for each treatment was recorded. The method used was a completely randomized design (CRD), where there were 3 treatments with repetition 3 times. The variables measured were the duration of the stunning process, sedative time and survival time. The research results showed that the higher the concentration of dried Plumeria acuminata extract, the higher the sedative time but the lower the stunning time. Apart from that, the results of this research also show that the higher the concentration of Plumeria acuminata extract is followed by the higher the survival rate.

Abstract

Tiram mutiara merupakan salah satu biota laut, yang hampir semua bagian dari tubuhnya mempunyai nilai jual, baik mutiara, cangkang, daging dan organisme tiram itu sendiri benih dan induk.Tiram jenis P. Margaritifera sering menjadi target utama masyarakat sebagai bahan konsumsi dikarenakan selain memiliki rasa yang lezat, tiram atau kerang juga mengandung protein yang cukup tinggi dan bermanfaat bagi tubuh. Namun saat ini, pengambilan tiram mutiara jenis ini masih mengandalkan dari alam. Sedangkan untuk kegiatan budidaya tiram mutiara jenis P.Margaritifera masih sedikit yang melakukannya. Hal ini tentu saja akan berdampak pada penurunan populasi tiram mutiara di alam.Penelitian ini menggunakan Perlakuan A (Kepadatan tiram mutiara sebanyak 25 ekor/keranjang) Perlakuan B (Kepadatan tiram mutiara sebanyak 30 ekor/keranjang) Perlakuan C ( Kepadatan tiram mutiara sebanyak 35 ekor/keranjang)Perlakuan D ( Kepadatan tiram mutiara sebanyak 40 ekor/keranjang). Hasil yang didapati menunjukan  kepadatan yang berbeda memberikan pengaruh nyata terhadap nilai pertumbuhan mutlak, namun tidak berpengaruh terhadap kelangsungan hidup. Nilai pertumbuhan mutlak  yang terbaik diperoleh pada perlakuan D yaitu dengan kepadatan 40 ekor. Sedangkan untuk nilai kelangsungan hidup  yang terbaik terdapat pada perlakuan D 76,33%.Kata kunci : Kepadatan, Tiram mutiara (P. margaritifera), laju pertumbuhan mutlak, kelangsunganhidupan

Abstract

In an effort to carry out cultivation activities, the obstacle is the availability of seeds is not met, so it is necessary to bring in seeds from other areas. To support cultivation activities, an effective transportation method is needed, one of which is dry system transportation or without water media. By carrying out dry transportation, it can save costs, reduce fish stress, and increase the number of transportation. This study was conducted using a completely randomized design (CRD) with 3 treatments and 3 replications, with the test organism being 5-6 cm white snapper seeds. The treatments tested were different densities, namely treatment A density of 10 fish, treatment B density of 15 fish, and treatment C density of 20 fish. Fish transportation was carried out with previous fish anesthesia, using commercial clove oil anesthetic with a dose of 0.10 ml / liter of seawater. Based on observations of transportation for 1 hour of travel, treatment C was the best treatment, namely with an inductive time of 4 minutes, a duration of unconsciousness of 1 hour, and a sedative time of 18 minutes, resulting in a post-transportation survival rate of 78% and a final maintenance survival rate of 76%. The use of clove oil is effective in maintaining the survival rate after dry transportation and after the end of the research on white snapper (Lates calcarifer) seeds.

Abstract

Saltwater ornamental fish have various species, many of which have been exported to various countries. One type of ornamental fish that can be kept in an aquarium is the clown fish (Amphiprion percula). However, clownfish tend to experience color fading when cultivated. This is caused by less than optimal food and lighting factors. The aim of this research is to determine the role of adding sweet potato flour (Ipomoea batatas) and ulva lactuca flour in feed to maintain the color of clownfish so that it remains as in nature and to support the growth of clownfish (Amphiprion percula). This research was carried out using four treatments and repeated three times, namely (1) F999 brand commercial feed, (2) 25% Ulva lactuca flour + 75% commercial feed, (3) 12.5% ​​Ulva lactuca flour + 12% sweet potato flour .5% + 75% commercial feed, (4) 25% sweet potato flour + 75% commercial feed. The parameters observed include color measurementsRed Green Blue (RGB) which is then converted to a color modelHue Saturation Brightness (HSB) and also growth. The research results show that fish color analysis usesHue Saturation Brightness (HSB), changes in hue values ​​tend towards yellow-orange colors. This shows similarities in maintaining color qualities found in clownfish in nature. However, there was no effect between different treatment on clown fish growth. The optimal dosage to achieve the desired fish color is to use 25% Ulva flour. Keywords: Amphiprion percula, sweet potato, ulva lactuca, color

Abstract

ABSTRACT Fasting is one of a method that used for measured growth of fish in a shorter period of time. This study was aimed to determine the optimum range of salinity for improve the survival and growth of glass eel Anguilla bicolor bicolor. It used a completely randomized design (CRD) with four salinity treatments and three replications, namely (A) 0 g/L, (B) 10 g/L, (C) 20 g/L, and (D) 30 g/L. The fish used were of glass eel A. bicolor bicolor with 0.15–0.23 g of weight. The experiment was conducted in an aquarium of 60×30×30 cm with a volume of 30 Liters and at a stocking density of 2 g/L for 14 days. During the maintenance, glass eels were fasted for have a significantly of biomass decline. Data collection was done at the start and the end of maintenance. Parameters measured included survival (%) and the rate of decline in absolute biomass (g). Physical and chemical parameters included temperature, dissolved oxygen, and pH which were measured daily, while ammonia and alkalinity were measured every seven days. Result showed that survival was not significantly different between treatments (P>0.05), while the rate of decline in absolute biomass was significantly different between treatments (P<0.05). Treatments of 0 g/L salinity was the lowest survival than the others. While treatment of 10 g/L salinity was the lowest rate of decline in absolute biomass. According to research, the optimum salinity was 10 g/L, and after analysis with quadratic regression analysis, the optimum range of salinity were 5.00–13.40 g/L. Keywords: optimum salinity, survival, growth, glass eel, Anguilla bicolor bicolor  ABSTRAK Pemuasaan merupakan salah satu metode pengukuran perubahan bobot ikan yang dipelihara dalam waktu singkat. Penelitian ini bertujuan untuk menentukan kisaran salinitas optimum untuk meningkatkan kelangsungan hidup dan pertumbuhan glass eel Anguilla bicolor bicolor. Rancangan penelitian yang digunakan adalah rancangan acak lengkap (RAL), dengan empat perlakuan salinitas dan tiga ulangan, yaitu (A) 0 g/L, (B) 10 g/L, (C) 20 g/L, dan (D) 30 g/L. Penelitian dilakukan selama 14 hari.  Ikan yang digunakan adalah glass eel A. bicolor bicolor dengan bobot 0,15–0,23 g dengan padat tebar 2 g/L. Pemeliharaan dilakukan di akuarium berukuran  60×30×30 cm dengan volume air 30 Liter/akuarium. Selama pemeliharaan glass eel dipuasakan sehingga diperoleh penurunan biomassa yang signifikan. Pengambilan sampel data dilakukan setiap tujuh hari berupa kelangsungan hidup (%) dan laju penurunan biomassa mutlak (g). Parameter fisika kimia air berupa ammonia dan alkalinitas dilakukan setiap tujuh hari, sedangkan suhu, oksigen terlarut (DO), dan pH dilakukan setiap hari. Hasil penelitian menunjukkan bahwa kelangsungan hidup tidak berbeda nyata antar perlakuan (P>0,05) sedangkan laju penurunan biomassa mutlak berbeda nyata antar perlakuan (P<0,05). Berdasarkan hasil penelitian, salinitas 10 g/L, 20 g/L, dan 30 g/L  menunjukkan kelangsungan hidup 100%, sedangkan salinitas 0 g/L memberikan kelangsungan hidup terendah. Salinitas 10 g/L menunjukkan pemakaian energi terendah untuk metabolisme tubuh sehingga memberikan penurunan bobot biomassa terendah dibandingkan dengan perlakuan lainnya.  Hasil penelitian menunjukkan salinitas optimum adalah 10 g/L, dan setelah dihitung menggunakan analisis regresi kuadratik, maka kisaran salinitas optimum adalah 5,00–13,40 g/L.   Kata kunci: salinitas optimum, kelangsungan hidup, pertumbuhan, glass eel, Anguilla bicolor bicolor
