Telah dilakukan kegiatan yang bertujuan mengetahui performa budidaya udang windu di tambak pembudidaya yang dilaksanakan pada musim kemarau tahun 2019 di Kecamatan Marusu Kabupaten Maros. Kegiatan budidaya udang windu teknologi tradisional plus dilaksanakan di tambak Dusun Kurilompo, Desa Nisombalia Kecamatan Marusu Kabupaten Maros. Sebanyak enam petak tambak pembudidaya ditebari tokolan udang windu dengan padat penebaran dari 10.000 sampai 30.000 ekor/ha. Setelah dipelihara selama 69 sampai 80 hari dilakukan panen dan selanjutnya dilakukan penentuan sintasan, bobot rata-rata, produksi udang windu, dan rasio konversi pakan (RKP). Data yang diperoleh dianalisis secara deskriptif. Hasil kegiatan menunjukkan bahwa kualitas air di tambak Kecamatan Marusu, Kabupaten Maros pada musim kemarau dicirikan dengan salinitas yang berkisar antara 36,63-69,40 ppt; suatu kondisi yang tidak optimal untuk budidaya udang windu. Pada saat panen didapatkan sintasan udang windu dari 27,57% sampai 66,67%; bobot rata-rata dari 14,29-40,00 g/ekor; produksi dari 90,1-800,0 kg/ha/musim; dan RKP dari 0,54:1 sampai 2,10:1. Disimpulkan bahwa budidaya udang windu di tambak bersalinitas tinggi di daerah ini merupakan penyebab utama rendahnya sintasan, bobot rata-rata, produksi udang windu, dan RKP. Direkomendasikan bahwa perbaikan budidaya udang dengan menjaga tingkat salinitas dalam nilai optimal harus disosialisasikan kepada pembudidaya udang windu di daerah tersebut.One of the main aquaculture development targeted by the South Sulawesi Province for the period 2018-2023 is to restore the glory of tiger shrimp farming in South Sulawesi. The recent study was carried out to uncover redevelopment opportunities of tiger shrimp culture and determine the performance of tiger shrimp culture in the farmers’ ponds. The study was performed during the dry season in Marusu Subdistrict Maros District, in 2019. Traditional plus tiger shrimp farming activities were carried out in the ponds of Kurilompo Subvillage, Nisombalia Village, Marusu Subdistrict, Maros District. A total of six brackishwater ponds were stocked with tiger shrimp fingerling with stocking densities of 10,000-30,000 ind./ha. After being cultured for 69 to 80 days, the shrimp were harvested and measured their survival rate, average weight, production of tiger shrimp, and feed conversion ratio (FCR). The data obtained were analyzed with descriptive statistics. The results showed that water quality in brackishwater ponds of Marusu Subdstrict Maros District, in the dry season is characterized by salinity ranging from 36.63 to 69.40 ppt, a condition that is not optimal for tiger shrimp culture. At harvest, the survival rate, average weight, production, and FCR of the farmed average tiger shrimp were 27.57%-66.67%, 14.29-40.00 g/ind., 90.1-800.0 kg/ha/season, and 0.54:1-2.10:1, respectively.

Pengaruh perbedaan jarak antara ikan sakit dengan ikan sehat terhadap perkembangan jumlah Pseudorhabdosynochus spp. pada ikan kerapu hibrida “cantik” dipelajari dalam penelitian ini melalui metode kohabitasi. Kohabitasi dilakukan dengan dua metode yaitu (a) menempatkan lima ekor ikan sakit ke dalam keranjang dengan jarak 25 cm dari dasar bak, dan (b) menempatkan lima ekor ikan sakit ke dalam keranjang dengan jarak 10 cm dari dasar bak. Kedua keranjang tersebut diapungkan ke dalam bak plastik berbeda dengan volume 100 L air laut (33 ppt) yang masing-masing telah berisi 30 ekor ikan kerapu hibrida “cantik” sehat. Masing-masing lima ekor ikan dari kedua metode kohabitasi diambil pada hari ke-2, 4, 6, 8, 10, dan 15 pemeliharaan. Hasil penelitian menunjukkan bahwa infeksi buatan menggunakan metode kohabitasi (b) lebih cepat menyebarkan Pseudorhabdosynochus spp. dari ikan sakit ke ikan sehat dibandingkan dengan metode kohabitasi (a). Perkembangan populasi Pseudorhabdosynochus spp. dan telurnya pada metode kohabitasi (b) lebih tinggi yaitu 1.495 ± 206,3 ekor/ikan dan 18,6 ± 3,8 telur/ikan dibandingkan dengan metode kohabitasi (a) yaitu 163,2 ± 16,3 ekor/ikan dan 3,8 ± 0,7 telur/ikan pasca 15 hari kohabitasi. Secara histopatologi, lamela insang yang terinfeksi Pseudorhabdosynochus spp. menunjukkan adanya hyperplasia epitel sel filamen insang yang menimbulkan fusi filamen. Kerusakan filamen di hampir semua lamela insang menyebabkan terganggunya sistem pernapasan ikan kerapu.

This study aimed to observe the changes of density patterns of Pseudorhabdosynochus spp. in hybrid grouper gill through cohabitation. Two cohabitation methods were applied to understand the effects of distance between sick and healthy fish in terms of parasite infection. The cohabitation methos were arranged as follows: (a) five fish infected with Pseudorhabdosynochus spp. were placed into a basket at a distance of 25 cm from the bottom of the tank, and (b) five fish infected with Pseudorhabdosynochus spp. were placed into a basket at a distance of 10 cm from the bottom of the tank. The two baskets were floated into different plastic tanks of 100 L of seawater (33 ppt), each of which contained 30 healthy hybrid groupers. Each of the five fish from the two cohabitation methods was sampled on day 2, 4, 6, 8, 10, and 15 after cohabitation. The results showed that the spread of Pseudorhabdosynochus spp. from sick fish to healthy fish with the cohabitation method b was faster than the cohabitation method a.

Salah satu faktor keberhasilan dalam pembenihan adalah kondisi lingkungan terutama suhu. Tujuan penelitian adalah untuk menentukan suhu optimal bagi perkembangan embrio, lama waktu penetasan, dan daya tetas telur ikan Tor soro. Penelitian dilakukan pada bulan September 2015 di Instalasi Riset Plasma Nutfah Perikanan Air Tawar, Bogor. Penelitian menggunakan rancangan acak lengkap (RAL) dengan empat perlakuan suhu (19°C-21°C, 22°C-24°C, 25°C-27°C, dan 28°C-30°C) dan tiga kali ulangan. Perbedaan suhu inkubasi pada penelitian ini mempengaruhi perkembangan embrio, lama waktu penetasan, dan persentase daya tetas pada telur ikan Tor soro. Suhu inkubasi yang tinggi (28°C-30°C) menyebabkan telur mati setelah delapan jam atau pada saat fase calon embrio. Suhu inkubasi 25°C-27°C menghasilkan waktu penetasan tercepat yaitu selama 77,33 ± 1,15 jam dengan daya tetas yang tinggi yaitu sebesar 84,44 ± 6,94%. Tor soro is a native freshwater fish to Indonesia. Despite its high value in local and national markets, the fish has not been widely and intensively cultured because its seed supply relies heavily on spawning in nature. One of the success factors of spawning a fish and rearing its seed in a hatchery is controlling environmental conditions, especially temperature. The aim of the study was to determine the optimal temperature for embryo development, hatching time, and hatchability of Tor soro eggs. The study was conducted in September 2015 at the Freshwater Fisheries Germplasm Research Installation, Bogor. A completely randomized design (CRD) was used in the experiment with four temperature treatments (19°C-21°C, 22°C-24°C, 25°C-27°C,and 28°C-30°C) and each treatment had three replications. Differences in incubation temperature in this study affect ed embryo development, hatching time, and the percentage of hatchability on Tor soro eggs. High incubation temperatures (28°C-30°C) had caused the eggs or embryo candidates to die off after eight hours.

Hasil menunjukkan bahwa kombinasi tanaman obat herbal dengan dosis yang diekstrak adalah 1:10 w/v (tanaman obat herbal: pelarut) efektif dalam menekan pertumbuhan bakteri Flavobacterium columnare secara in vitro dengan diameter zona bening 16 ± 3 mm. Sementara untuk jamur yang tidak diidentifikasi spesiesnya dosis yang mampu mematikan pertumbuhan hifanya adalah 300 mL/mL-1 dan pada dosis 1 g.L-1 serbuk kombinasi tanaman obat herbal mampu menurunakan jumlah parasit dari kelompok Trichodina, Gyrodactylus, dan Dactylogyrus mulai hari ke-2 pasca perendaman. Sedangkan dosis aman yang dapat digunakan oleh ikan lele adalah 1,82 g.L-1. Catfish is a valuable fish commodity in local and national markets. The increasing demand for catfish has led to the farming intensification of the fish. As a result, fish disease outbreaks frequently occur in most of catfish farming centres. Efforts to prevent these outbreaks and reduce the use of antibiotics and other chemical have been developed primarily through the use of natural ingredients such as medicinal herbs. This study was aimed to study the potential use of six medicinal herbs combination in controlling diseases in catfish caused by bacteria, fungi and parasites. The results showed that the medicinal herbs' combination effectively suppressed the growth of the bacterium Flavobactrium columnare in vitro with a clear zone diameter of 16 ± 3 mm after the application of the herbs combination extract of 1:10 w/v (herbs: solvent). The extract dosage use of 300 mL/mL-1 was able to destroy the hyphal structure of an unidentified fungus. At a dose of 1 g.L-1, the powder form of the combination of the medicinal herbs was able to reduce the number of parasites of Trichodina, Gyrodactylus and Dactylogyrus on the 2nd day after immersion. This study recommends that the safe dose of the extract for catfish is 1.82 g.L-1.","PeriodicalId":334563,"journal":{"name":"Media Akuakultur","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129731600","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Masalah yang sering dihadapi adalah terjadinya kematian benih ketika ditransportasikan akibat stres. Daun ubi kayu memiliki kandungan flavonoid dan saponin yang bermanfaat sebagai pencegah stres pada ikan selama proses pengangkutan. Penelitian ini bertujuan untuk menentukan konsentrasi optimal penambahan perasan daun ubi kayu aksesi batin sebagai bahan anestesi alami pada transportasi sistem tertutup benih ikan nila. Konsentrasi daun ubi kayu aksesi batin yang diujikan adalah 0 g/L (P-0/kontrol); 6,25 g/L (P-1); 7,50 g/L (P-2); dan 8,75 g/L (P-3). Ikan ditransportasikan pada sistem tertutup selama delapan jam dengan suhu udara berkisar 28°C-30°C. Hasil penelitian menunjukkan bahwa penambahan perasan daun ubi kayu aksesi batin pada masing-masing perlakuan menghasilkan kelulushidupan benih ikan nila sebesar 80% (P-0/kontrol), 100% (P-1), 98% (P-2), dan 38,88% (P-3); dengan kadar glukosa darah sebesar 245 mg/dL (P-0/kontrol); 102,33 mg/dL (P-1); 196,66 mg/dL (P-2); dan 307,66 mg/dL (P-3). Konsentrasi terbaik untuk aplikasi transportasi benih ikan nila adalah konsentrasi 6,25 g/L. Pada konsentrasi tersebut kondisi ikan tidak mengalami stres yang dominan dengan sedikit perubahan kadar glukosa darah yang relatif rendah dan mempertahankan kondisi kualitas air lebih baik dibandingkan dengan kontrol dan perlakuan lainnya. Market demands for tilapia are steadily increased annually which require a sustainable and consistent availability of its seed supply. One of the issues in the supply chain of tilapia seed is the juvenile mortality during transportation caused by a prolonged stress. Cassava leaf contains flavonoid and saponin, which were suspected to be useful to prevent fish stress during the transportation process. This research aimed to determine the optimal concentration of cassava leaf extract of Batin accession as a natural anesthetic to nile tilapia transported in a closed system. The concentrations of cassava leaf extract of Batin accession used in this research were 0 g/L (P-0, control treatment), 6.25 g/L (P-1), 7.50 g/L (P-2), and 8.75 g/L (P-3). Tilapia seeds were transported within a closed transportation system for eight hours, with air temperatures ranging between 28°C-30°C. The results showed that the addition of cassava leaf extract of Batin accession in each treatment produced survival rates of tilapia seed of 80% (P-0/control), 100% (P-1), 98% (P-2), and 38.88% (P-3), with blood glucose levels of 245 mg/dL (P-0/control), 102.33 mg/dL (P-1), 196.66 mg/dL (P-2), and 307.66 mg/dL (P-3). The best concentration of cassava extract for tilapia seed transportation was achieved by treatment P-1. The concentration of cassava extract used in P-1 was successfully reduced the seed stress level indicated by a relatively slight change in the blood glucose level. The concentration was also proved to keep better conditions of t","PeriodicalId":334563,"journal":{"name":"Media Akuakultur","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-06-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125046313","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
