Abstract

Eel (Anguilla sp.) is one of the important commercial fish in some countries particularly in East Asian countries such as Japan, South Korea, China, and Taiwan. The need of eel fry or frequently called as glass eel still relies on the natural capture. The issue of natural captured fish is the high level of bacterial infections and diseases. The dependence of glass eel from the nature provides an indication of infections of parasites and bacteria in glass eel. The existence of parasites and bacteria as microorganisms which are potential as pathogenic agents in the cycle of eel culture can be a serious obstacle, so that the glass eel handling needs a particular attention since the capturing proses from the nature. Therefore, identification of parasites and bacteria in the capture location of glass eel was necessarily conducted in Pelabuhan Ratu Bay, Sukabumi, West Java. The glass eel sampling was conducted in May-June 2019, in 3 locations of estuary with the highest capture yield namely Cimandiri River, Cikaso River and Cibuni River. The number of samples taken were 30 eels at each river location with 2 replicates, so that the total eel samples which were taken were 180 eels. Identification of parasites was conducted by examination of ectoparasite and endoparasite and dentification of bacteria was conducted by conventional method (biochemical method). Based on the result of identification, there was no parasite found in the glass eel samples, while bacteria found as many as 12 species and 3 dominant species namely Listeria sp. found in 40 eel samples with prevalence of 22.2%, Aeromonas hydrophila found in 28 eel samples with prevalence of 15.6%, and Staphylococcus spp. found in 22 eel samples with prevalence of 12.2%.Keyword : Micro-organism, Pathogen, Glass Eel, Anguilla spp.

Abstract

Indonesia has a lot of potential in natural resources, one of which is seaweed. Seaweed is one of the natural ingredients that contain water-soluble dietary fiber. The fiber content in seaweed can be categorized as a functional food. The fiber content in seaweed varies, from 36-60% dry weight, 55-70% of the former percentage is soluble fiber consisting of alginate and carrageenan with varying amounts depending on the type of seaweed and environmental conditions. The dietary fibers are useful for disease prevention and health maintenance. Dietary fiber can prevent several diseases, including coronary heart disease (cardiovascular). The effect of dietary fiber according to Liu et al (2002) is a very high fiber diet (55 g/1,000 kcal) which resulted in a 33% reduction in LDL cholesterol (Low-Density Lipoprotein) in two weeks period. The mechanism of dietary fiber reduces cardiovascular disease since it is able to bind bile acids (the end product of cholesterol), thereby preventing its reabsorption from the intestine. Cholesterol that is bound to bile acids and lignin/pectin cannot be absorbed by the intestines but will be excreted in the feces.

Abstract

This study aimed to evaluate S. platensis powder dietary supplementation on the growth performance and color quality of polar blue cichlids. This study used a completely randomized design experimental method with four different dietary supplementation doses of S. platensis powder, namely 10 g/kg diet (A), 20 g/kg diet (B), 30 g/kg diet (C), and 0 g/kg diet (K). These treatments were replicated four times. The polar blue cichlids as fish samples had 4.07 ± 0.12 cm and 2.15 ± 0.22 g. Diets (38% protein) were produced by coating the commercial feed with S. platensis powder in appropriate dosage. Feeding was performed until apparent satiation twice a day for 45 days. All parameters, including growth performance (feed intake, weight gain, length gain, specific growth rate, feed conversion ratio, survival rate) and color quality (total grid percentage and total chromatophores), were analyzed using an analysis of variance and the Duncan's multiple range test was applied to obtain the best treatment in growth performance and color quality. The dietary supplementation of S. platensis powder had no significant effect on the growth performance of polar blue cichlids. However, this treatment provides a higher total grid percentage of blue color and total chromatophores in the fish. The best treatment on color quality was found in a 30 g/kg diet dose of S. platensis powder. Therefore, 30 g/kg dose of S. platensis powder is effective to improve the color quality of polar blue cichlids, although providing no significant effect on the growth of the fish.

Abstract

PT Iroha Sidat Indonesia (PT ISI) melakukan proses budidaya ikan sidat di Banyuwangi dan sangatbergantung pada penggunaan air tawar. Proses tersebut diduga memberikan pengaruh terhadap kondisipermukaan tanah di sekitar lokasi tambak PT ISI. Sebagai bagian dari kegiatan Aquaculture Improvement Program (AIP) yang bekerjasama dengan WWF Indonesia, dilakukan kajian untuk mengetahui pengaruhaktivitas sumur bor (pompa) terhadap Penurunan Muka Tanah (PMT) di tambak PT ISI. Kajian ini dilakukandengan metode DInSAR (Differential Interferometric Synthetic Aperture Radar), yaitu metode denganperpaduan dua citra radar dengan fase berbeda untuk memperoleh pergeseran tanah. DInSAR akanmemberikan hasil analisis deformasi hingga pada ketelitian sub-sentimeter. Analisis DInSAR dilakukanmenggunakan citra Sentinel 1A tahun 2014, 2016, 2017, 2018 dan 2019 dan proses pengolahan citradilakukan dengan menggunakan software SNAP v.7.0. Hasil pengolahan citra Sentinel 1A per-tahun menunjukkan adanyadeformasi vertikal yang terjadi di sekitar area tambak PT ISI. Hasil tersebut menunjukkanadanya variasi deformasi vertikal setiap tahunnya, dimana terjadi subsidence (penurunan) dan juga uplift(kenaikan). Nilai PMT yang terjadi dari tahun 2014 hingga 2019 berkisar antara (-0,001) – (-0,031)meter/tahun, sedangkan nilai kenaikan yaitu 0,016 meter/tahun. Hal ini dapat menjadi salah satu bahanpertimbangan oleh PT ISI untuk melakukan efisiensi dalam penggunaan air tanah. Dalam kajian juga ditemukan adanya proses penambangan pasir di sekitar tambak PT ISI, sehingga diperlukan kajian lebihdalam untuk mengetahui spesifikasi pengaruh terjadinya PMT yang diakibatkan oleh pompa dan penambangan pasir

Abstract

Feed is one of the main components with important function to support the freshwater fish culture success. Sufficient feed quantity and quality can ensure the fish culture cycle continuity. Feed occupies the highest position, which spends 60-80% of the total production cost requirement in intensive fish culture to support the fish growth. The high feed cost is unmatched with the fish selling price, resulting in a minimum profit gain. Based on this condition, a community service, focusing on self-produced feed training needs to be implemented to increase the cost efficiency and effectiveness in freshwater fish culture. This training was conducted in Gunungpring Village, Muntilan Sub-district, Magelang District with fish cultivator communities. The feed used as the object for this training contained artificial and live feed. Training activities contained surveys, field observations, outreach, counseling, mentoring, monitoring, and evaluation. This training could clearly introduce the community to the use of alternative feeds for ornamental and consumed-fish commodities. Live feed production training included Azolla sp., Daphnia sp., silkworms, and earthworms, while artificial feed included pellets of pf500-1000. This training program increases the community understanding and skills, followed by the quality and quantity of fishery products. As the training also has an impact on the regional food security with massive community assistance, so harvest failure can be minimized optimally.

Abstract

Yellowfin tuna merupakan komoditas perikanan yang memiliki nilai ekonomis tinggi. Kendala utama dalam budidaya yaitu terjadi kematian massal pada stadia awal pemeliharaan larva. Pengamatan terkait perkembangan awal organ larva yellowfin tuna secara histologi perlu dilakukan untuk mendapat informasi dasar dalam pengembangan teknik pemeliharaan larva. Tujuan dari penelitian ini adalah untuk mengetahui perkembangan organ penglihatan, penciuman, gelembung renang dan sistem pencernaan larva secara histologi. Sampel larva diambil sebanyak 15 ekor pada umur satu hari (D1), D3, D5, D7, D10 dan D13. Metode histologi yang digunakan adalah metode Bouins. Sampel direndam selama 4–6 jam pada larutan bouins, dipindahkan ke dalam larutan berisi alkohol 70% untuk didehidrasi dengan konsentrasi bertingkat hingga 100%. Sampel dijernihkan dalam xylene dan diresapkan dalam paraffin, dipotong dengan microtom dan pewarnaan dengan haematoxylin dan eosin. Hasil menunjukkan pada D1 sistem pencernaan berbentuk tabung lurus sederhana, sistem penglihatan, penciuman dan gelembung renang belum terbentuk sempurna. Hari ke 3 saluran pencernaan mulai terbentuk, organ telinga dalam, penciuman, mata, esofagus, lambung dan ginjal juga sudah mulai terbentuk. Retina dan pigmen mata sudah berkembang lebih baik, gelembung renang juga sudah terbentuk dan organ penciuman semakin jelas pada umur D5. Organ-organ larva terus berkembang seiring dengan pertumbuhan dan pertambahan umur larva. Berdasarkan perkembangan penglihatan, penciuman, pencernaan larva yellowfin tuna sudah bisa diberikan pakan pertama pada hari ke 3 setelah menetas.
