Penyebabnya adalah penyetruman dianggap membahayakan keselamatan manusia dan merusak ekosistem perairan. Penelitian mencoba mendapatkan arus listrik yang aman dan efektif untuk menangkap lele ( Clarias sp.) layak tangkap tanpa merusak lingkungan perairan. Arus listrik yang diinginkan dapat memingsankan lele layak tangkap dengan cepat, tetapi waktu siumannya lambat, sehingga memberi waktu yang cukup lama untuk penangkapannya.  Jumlah lele yang diuji sebanyak 90 ekor yang dibagi atas 3 kelompok dengan panjang total tubuh antara 18,5-32,5 cm. Masing-masing terdiri atas 30 lele yang disetrum dengan arus listrik 1 mA , 2 mA , dan 3 mA .  Ketiga besaran arus listrik masih dianggap aman karena belum memberikan efek negatif bagi tubuh manusia (Ouazani et al. , 2012). Hasilnya adalah penyetruman lele sebaiknya menggunakan arus listrik 2 mA , karena aman bagi manusia dan efektif untuk menyetrum lele. Waktu pingsan lele berukuran layak tangkap yang memiliki panjang tubuh ≥ 24,5 cm antara 83 – 140 detik, atau lebih cepat dibandingkan dengan 1 mA (120-309 detik), sedangkan waktu siumannya  117-225 detik atau lebih lama dari 3 mA (79-125 detik). Electrofishing currently has been banned by Indonesian Government since 2004, regardless, some of the people still do that secretly. The banning caused by the thought that electrofishing indeed harmful to human safety and aquatic ecosystem. This research aimed to obtain the electricity current that safe and effective to catch  the proper size of catfish (Clarias sp.) without harming the aquatic ecosystem. Desired electricity current strength is the one that able to temporarily immobilised catfish quickly with long time to be conscious so gives longer time in harvesting activity. The amount catfish used in the experiment was 90 fishes with average body length 18.5-32.5 cm, divided in to 3 groups.

Pengujian dilakukan untuk mengamati pola dan laju respons mimi terhadap tiga intensitas cahaya lampu LED merah. Spesies mimi yang dijadikan objek penelitian adalah Tachypleus gigas . Jumlah mimi yang digunakan sebanyak 20 ekor dengan panjang total 30-38 cm. Analisis data yang digunakan adalah metode deskriptif komparatif. Hasil penelitian menunjukkan terdapat respons mimi menjauhi cahaya terbanyak pada LED merah intensitas rendah sebanyak 60%, sedangkan intensitas sedang dan tinggi sebanyak 35% dan 34%. Adapun waktu respons mimi yang tersingkat terdapat pada intensitas cahaya LED rendah selama 32,05 detik dan waktu respons terpanjang terdapat pada intensitas tinggi selama 59,06 detik. Berdasarkan respons penghindaran tersebut, lampu LED dengan intensitas 3,68 × 10 -6 W/cm 2 dapat digunakan sebagai alternatif dalam mitigasi bycatch mimi pada perikanan jaring insang dasar.

Cultivation process to produce koi with the best quality is still have problem, one of the problem is parasitic infection of Myxobolus sp. which can cause mass death in a short time. Myxobolus attacks fish tissue can cause severe damage to tissue. Many ways were used by koi fish farmers to avoid Myxobolus infection which  with natural treatment and using chemicals drug. This study aims to determine the hematological effects and immune respons in the koi fish infected with the Myxobolus and treated with dimilin. Experimental method was used in this research with control treatment of healthy fish (A), koi fish infected by Myxobolus sp. without treatment (B), koi fish infected by Myxobolus sp with dimilin treatment 0.02 mg (C), and koi fish infected by Myxobolus sp with dimilin treatment 0.01 mg (D). fish Blood samples were collected with puncture of caudal vessel method and then haematological observations to blood samples, and immunohistokima observations by looking percentage of Diaminobenzidine (DAB) in fish. Highest hematological Results of leukocytes and erythrocytes were found ","PeriodicalId":193095,"journal":{"name":"SAINTEK PERIKANAN : Indonesian Journal of Fisheries Science and Technology","volume":"142 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-08-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123293435","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}

Dalam praktek akuakultur, probiotik telah digunakan dalam beberapa tahun terakhir probiotik menjadi bagian integral dari praktik budaya untuk meningkatkan pertumbuhan dan ketahanan terhadap penyakit. Tujuan penelitian ini mengetahui pengaruh pemberian probiotik terhadap hematologi dan respon imun ikan koi yang terserang Myxobolus sp. yakni eritrosit dan leukosit serta ekspresi Nuclear Factor-kappa Beta (NF-kB). Metode yang digunakan yaitu metode eksperimen. Dalam penelitian ini dibagi ke dalam 4 perlakuan yaitu, perlakuan (A) Kontrol, (B) ikan koi terinfeksi Myxobolus sp., (C) ikan koi terinfeksi Myxobolus sp. dengan pemberian probiotik dosis 0,55 ml dan (D) ikan koi terinfeksi Myxobolus sp. dengan pemberian probiotik dosis 1,1 ml. Metode pemberian perlakuan dengan menambahkan probiotik pada 30 liter air pada bak pemeliharaan. Kemudian dilakukan pengamatan eritrosit dan leukosit. Serta dilakukan Imunohistokimia menggunakan antibodi NF-kB pada jaringan insang. Berdasarkan hasil pengamatan eritrosit diperoleh nilai rata – rata pada perlakuan A sebesar 1.666.667 sel/mm 3 , perlakuan B sebesar 1.940.000 sel/mm 3 , perlakuan C sebesar 1.776.667 sel/mm 3 dan perlakuan D sebesar 1.836.667 sel/mm 3 . Hasil pengamatan leukosit diperoleh nilai rata – rata pada perlakuan A sebesar 119.800 sel/mm 3 , perlakuan B sebesar 492.800 sel/mm 3 , perlakuan C sebesar 308.533 sel/mm 3 dan perlakuan D sebesar 318.400 sel/mm 3 . Selanjutnya, berdasarkan hasil Imunohistokimia  didapatkan hasil pada perlakuan A nilai DAB sebesar 15,1%, perlakuan B nilai DAB sebesar 31,7%, perlakuan C nilai DAB sebesar 53,5% dan pada perlakuan D nilai DAB sebesar 47,5 %. Dari penelitian ini dapat disimpulkan bahwa pemberian probiotik berpengaruh terhadap eritrosit dan leukosit serta dapat meningkatkan ekspresi NF-KB sebagai respon imun pada ikan koi ( Cyprinus carpio ) yang terinfeksi Myxobolus sp. Dosis optimal pemberian probiotik yaitu pada dosis 0,55 ml. Myxobolus is a dangerous parasite that can kill up to 80% on koi carp pond.. Probiotic intake has been proven to change the composition of the microbiota, and therefore helps in the recovery of microbiota that are disrupted (by antibiotics or other risk factors) into favorable or normal compositions. The purpose of this study was to determine the effect of probiotic administration on hematology and the immune response of koi fish attacked by Myxobolus sp. namely erythrocytes and leukocytes and expression of Nuclear Factor-kappa Beta (NF-kB). The method used was an experimental by providing probiotics to fish that promoted Myxobolus sp. In this study it was divided into 4 treatments namely, (A) Control, (B) koi carp infected by Myxobolus sp., (C) koi carp infected by Myxobolus sp. with probiotic doses of 0.55 ml and (D) koi fish infected by Myxobolus sp. by administering a probiotic dose of 1.1 ml.
