Insektisida golongan organofosfat telah digunakan secara ekstensif dalam bidang pertanian untuk mengontrol hama dan meningkatkan hasil produksi pertanian guna memenuhi permintaan bahan pangan yang tinggi akibat pertumbuhan populasi penduduk yang cepat. Akan tetapi walaupun penggunaan pestisida golongan organofosfat secara nyata telah menigkatkan hasil produksi pertanian, penggunaannya yang tidak terkontrol dapat membahayakan berbagai organisme akuatik dan dapat mengakibatkan efek negatif jangka panjang terhadap lingkungan perairan. Penelitian ini bertujuan untuk mengevaluasi pengaruh berbagai konsentrasi golongan organofosfat (0,0002 ml/L, 0,0004 ml/L dan 0,0005 ml/L Parathion 25%) terhadap kelangsungan hidup dan histologi jaringan hati dan insang benih ikan nila GIFT (Oreochromis niloticus, Bleeker). Benih ikan nila yang telah terpapar dengan berbagai konsentrasi pestisida tersebut menunjukkan beberapa gejala klinis diantaranya: kesulitan respirasi, perubahan warna tubuh menjadi lebih hitam, warna mata dan insang terlihat pucat, kehilangan keseimbangan dan berenang tidak beraturan sebelum kematian. Penelitian ini menunjukkan bahwa dengan semakin tinggi konsentrasi pestisida yang diberikan mengakibatkan semakin rendahnya kelangsungan hidup benih ikan nila. Kelangsungan hidup benih ikan nila yang dipapar dengan konsentrasi pestisida tertinggi (0,0005 ml/L) adalah 6,67%. Selama penelitian ini berlangsung, kelangsungan hidup benih ikan nila yang digunakan sebagai kontrol negatif adalah 100%. Pengamatan histologi jaringan hati dan insang memperlihatkan beberapa kerusakan jaringan akibat paparan Parathion, diantaranya: hemoragi, vakuola, degenerasi sel, telangiaktasis, dan hiperplasia dan kongesti jaringan insang. Penelitian membuktikan bahwa pestisida organofosfat khususnya Parathion 25% memiliki efek negatif terhadap kelangsungan hidup dan mengakibatkan perubahan histologi jaringan hati dan insang benih ikan nila GIFT.Insecticides such as organophosphates, have been used extensively in agriculture to control pest and improve crop yield to meet the high demand for food needed by the fast growing population. However, even though the use of organophosphate pesticides has been substantially increased agriculture crops, indiscriminate use of this chemical substance may cause harmful effects on aquatic organisms and may contribute long-term effects in aquatic environment. The purpose of this current study was to evaluate the effects of commercial organophosphate pesticide (Parathion 25%) on the survival and histopathological changes of GIFT (Genetically Improved Farmed Tilapia) Nile tilapia (Oreochromis niloticus, Bleeker) juveniles following exposure to varying concentrations of the toxicant (0.0002 ml/L, 0.0004 ml/L and 0.0005 ml/L, respectively). Following exposure to this pesticide, exposed fish were observed to exhibit some clinical signs including respiratory distress (such as gasping in air), darkened body color, opaque eyes and pale gills. Loss of balance and erratic swimming prior to death were also observed. As the concentration of pesticide increased, the survival rate of exposed fish reduced. This study found that at the highest concentration given (0.0005 ml/L) resulted in 6.67% survival of exposed fish. In the contrary, none of negative control fish were died during the period of this experiment. The histological observation of liver and gill tissues of exposed fish showed a deleterious effect of Parathion ranged from hemorrhage, vacuolization, cell degeneration, telangiectasia, hyperplasia and congestion of gills. This study provides more evidence that organophosphate pesticide, particularly Parathion 25%, has negative side effects on the survival and causes histological changes in liver and gills tissues of GIFT Nile tilapia juveniles.

Pertumbuhan yang relatif lama menjadi salah satu kendala dalam komoditas perdagangan khususnya ikan koi. Kebutuhan pakan yang sangat tinggi sangat menjadi masalah bagi para pembudidaya ikan koi. Salah satu cara yang bisa dilakukan untuk mencapai tujuan tersebut adalah dengan memberikan hormon tiroksin dan hormon rGH ke dalam makanannya agar dapat memberikan percepatan pertumbuhan. Penelitian ini dilaksanakan pada bulan Februari-Maret 2016 yaitu di Laboratorium Hatchery dan Teknologi Budidaya Perairan Program Studi Budidaya Perairan Fakultas Pertanian Universitas Malikussaleh. Penelitian ini bertujuan untuk mengetahui pengaruh pemberian hormon tiroksin dan hormon rGH melalui metode oral dengan dosis yang berbeda terhadap pertumbuhan dan kelangsungan hidup benih ikan koi (Cyprinus carpio L). Penelitian ini menggunakan metode eksperimental dengan menggunakan rancangan acak lengkap (RAL) non-faktorial dengan empat perlakuan tiga kali ulangan. Hasil penelitian dengan pemberian hormon tiroksin dan hormon rGH dengan dosis yang berbeda tidak menunjukkan pengaruh yang nyata terhadap pertumbuhan bobot, panjang, kelangsungan hidup dan konversi pakan. Perlakuan D dengan dosis T4 25 mg/kg dan hormon rGH 2,5 mg/kg pakan menghasilkan nilai pertumbuhan bobot sebesar 0,60 gr dan panjang 0,54 cm. Nilai kelangsungan hidup pada setiap perlakuan dengan nilai sebesar 100%. Nilai konversi pakan terbaik pada perlakuan D sebesar 1,92. Nilai kisaran kualitas air selama penelitian yaitu suhu 27-28 oC, pH 7.0-7.9, DO 5.9-6.9 ppm dan amonia 0,0359 – 0,1946 ppm.Relatively slow growth becomes one of the obstacles in trading commodities, especially on koi fish. A high feed requirement becomes a problem for the koi fish farmers. One way that can be done to achieve that goal is by giving thyroxin hormone and rGH hormone into its feed in order to deliver a growth acceleration. This research was conducted in February - March 2016 in the Hatchery and Aquaculture Technology Laboratory at the department of Aquaculture, Agriculture Faculty, Malikussaleh University.
