Serangan penyakit bercak merah ( Motile Aeromonas Septicemia )   masih merupakan kendala dalam budidaya ikan tersebut.  Penyakit ini disebabkan oleh bakteri genus Aeromonas, antara lain  Aeromonas hydrophila .  Untuk mengatasi infeksi bakteri tersebut dimungkinkan untuk menggunakan bahan herbal.  Kulit batang kelor merupakan bahan herbal yang berpotensi sebagai antibakteri.  Tujuan dari penelitian ini adalah mengkaji pengaruh  ekstrak kulit batang kelor terhadap status kesehatan dan kelulushidupan  ikan mas yang diinfeksi  A. hydrophila .   Ikan uji  yang digunakan adalah 120 ekor dengan rata-rata bobot 13,58 ± 2,83 g dan rata - rata panjang 9,93± 0,72 cm yang di infeksi A. hydrophila sebanyak 0,1 mL secara intramuscular dengan kepadatan bakteri 10 7 CFU/mL. Penelitian ini menggunakan metode eksperimental dengan rancangan acak lengkap 4 perlakuan 3 ulangan. Perlakuan yang diberikan adalah perendaman ekstrak kulit batang kelor dengan konsentrasi 0 mg/L ( perlakuan A), 1000 mg/L (perlakuan B ), 2000 mg/L (perlakuan C ) dan 3000 mg/L (perlakuan D).  Metode perendaman yang digunakan adalah  long bath selama 2 jam.  Perendaman dilakukan setelah gejala klinis dari infeksi A. hydrophila muncul.  Data status kesehatan yang diamati meliputi kelulushidupan, eritrosit, leukosit dan hematokrit. Hasil penelitian menunjukkan bahwa perendaman ekstrak kulit batang kelor berpengaruh nyata terhadap kelulushidupan,  eritrosit, leukosit dan hemoglobin  ikan mas (P 0.05).  Kosentrasi  ekstrak kulit batang kelor  1000 - 3000 mg/L dapat digunakan untuk mengobati ikan mas yang terinfeksi bakteri A. hydrophila. Kelulushidupan tertinggi  83,3± 5,77% dicapai pada perendaman 3000 mg/L.

The moringa skin stem extract were A (0 mg / L), B (1000 mg / L), C (2000 mg / L) and D (3000 mg /L) and immersed for 2 hours. Experimental carps were infected with 0.1 mL A. hidrophila at concentration of 10 7 CFU/mL pour to treatment until appeared clinical sign.

Sumber cahayanya sangat beragam, mulai dari petromaks, lampu pijar, lampu neon dan mercury. Nelayan terpaksa mulai meninggalkan pengunaan keempat lampu karena bahan bakar sebagai sumber energinya sangat mahal. Jenis sumber cahaya yang sangat berpeluang besar dikembangkan adalah lampu LED, karena lebih hemat energi, ramah lingkungan dan tahan lama. Uji coba lampu LED jenis HPL pernah dilakukan pada perikanan bagan tancap. Hasilnya membuktikan bahwa bagan yang mengoperasikan lampu HPL mendapatkan berat tangkapan 2 kali lebih tinggi dibandingkan dengan bagan nelayan yang menggunakan lampu neon. Penelitian dilakukan untuk memperbaiki konstruksi penelitian sebelumnya agar pancaran cahayanya semakin luas. Selanjutnya, berat hasil tangkapan bagan apung yang mengoperasikan lampu berbeda dibandingkan. Tujuannya adalah untuk membuktikan bahwa penggunaan lampu konstruksi baru dapat meningkatkan berat hasil tangkapan bagan, tanpa mengurangi komposisi jenisnya. Hasilnya adalah berat total hasil tangkapan bagan yang mengoperasikan lampu dengan konstruksi baru mencapai 1494 kg yang didominasi oleh hasil tangkapan utama seberat 847 kg dan sampingan 647 kg, atau lebih tinggi dibandingkan hasil tangkapan total lampu konstruksi lama 788 kg  (433 kg; 355 kg). Komposisi jenis hasil tangkapan kedua lampu terdiri atas delapan jenis organisme yang sama, yaitu teri putih ( Stolephorus buccaneeri ), teri jengki, teri hitam, teri paku ( Stolephorus indicus ), cumi-cumi ( Loligo sp.), pepetek ( Leiognathus sp. ), selar kuning ( Selaroides leptolepis ) dan tembang ( Sardinella fimbriata ). Light is the main fish aggregat device on the lift net fishing as fish collector. The source of light is various, i.e. petromaks, fluorescent lamp, neon lamp, and mercury. The fisherman is forced to abandon the use of the lamps because the fuel cost is high. The kind of light sources that have big opportunity to be developed is LED because it is lower energy, enviromentally friendly, and durable. The trials of HPL lamp had been carried out on the lift net fishing. The result showed that the weight of fish catches on the lift net with HPL lamp was higher twice than lift net with neon lamp. The research handled to fix the contruction on the previous research was carried out to make the emission of the light widen. Then, the weight of fish catches on the lift net with different lamp could be compared. This research aimed to prove the use of lamp with new contruction could increase the weight of fish catches on the lift net without decreasing the species composition. The result showed the weight of fish catches on the lift net with new contruction was 1494 kg that was dominated by main catch 847 kg and by catch 647 kg or more than the total weight of the HPL-S lamp 788 kg (433 kg; 355 kg). the species composition of both of the lamp were 8 species, i.e, white ancovy, jengki ancovy, black ancovy, ","PeriodicalId":193095,"journal":{"name":"SAINTEK PERIKANAN : Indonesian Journal of Fisheries Science and Technology","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125935843","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}

Salinitas memberikan pengaruh terhadap tekanan-tekanan osmotik yang berbeda terhadap tekanan osmotik tubuh organisme perairan, sehingga mengharuskan untuk melakukan proses osmoregulasi untuk menyeimbangkan tekanan osmotiknya. Tujuan dari penelitian ini adalah mengetahui tingkat kerja osmotik (TKO), indeks ponderal, dan kematangan gonad kepiting bakau serta hubungan TKO dengan indeks ponderal dan kematangan gonadnya. Penelitian dilakukan pada bulan Desember sampai Maret 2019. Materi utama yang dijadikan objek pengamatan adalah kepiting bakau yang dibudidaya di tambak Desa Pesantren Ulujami Pemalang. Metode penelitian yang digunakan adalah studi kasus menggunakan analisis deskriptif dan korelasi dengan pengambilan sampel menggunakan metode purposive sampling. Hasil penelitian menunjukkan kepiting bakau di tambak Desa Pesantren memiliki pola osmoregulasi hiperosmotik sedangkan pola osmoregulasi isoosmotik ditunjukkan pada kepiting yang sedang mengalami moulting. Indeks ponderal kurang dari dua sehingga bertubuh pipih dan belum matang gonad. Adapun tekanan osmotik berpengaruh negatif terhadap indeks ponderal dan kematangan gonad kepiting.","PeriodicalId":193095,"journal":{"name":"SAINTEK PERIKANAN : Indonesian Journal of Fisheries Science and Technology","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-04-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130522028","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}
