Abstract

Pangasianodon hypophthalmus is a freshwater fish that can grow well in dark condition. In no light condition, fishes are more responsive to feed provided. However, phytoplankton may not grow well, and as a consequence the water quality was poor and it negatively effects the fish health in general. The combination of biofloc and photoperiod manipulation systems is expected to improve the water quality as well as the fish health. To understand health status of the fish in general, the histological structure gill, kidney and liver was investigated. Sample were fixed in 5% formalin, paraffin processed and Haematoxylin Eosin stained. There were 2 factor, 3 treatment applied, namely natural (control), 18G (18 hours dark), 24G (24 hours dark) and 3 repetition. Parameter measured were survival rate and histological structure of gill, kidney, intestine and liver. Results shown that there are not difference of histological structure of the organs of fish reared under biofloc and manipulated photoperiod systems. There were light abnormalities in the gill, such as hyperplasia, hypertrophy, oedema and necrosis. There is no negative effect of biofloc system and photoperiod manipulation in structure of fish organ as there is only light abnormalities that can be cured when the water quality is good.

Abstract

Ikan badut (Premnas biaculeatus) merupakan salah satu komoditas unggulan ikan hias air laut yang hidup di perairan terumbu karang bersimbiosis dengan anemon dan memiliki nilai ekonomis yang tinggi. Tujuan dari kegiatan ini adalah untuk mendapatkan pengetahuan dan pengalaman mengenai teknik pemijahan pada ikan badut (P. biaculeatus) di Balai Perikanan Budidaya laut (BPBL) Batam. Kegiatan ini dilaksanakan pada bulan Januari –Februari 2020 bertempat di Balai Perikanan Budidaya Laut (BPBL) Batam. Metode yang digunakan dalam kegiatan ini adalah pengarahan (mentorial), praktek langsung dan studi literatur. Pemijahan ikan badut diseleksi melalui ukuran tubuh ukuran tubuh 4-6 cm dianggap sebagai jantan dan ukuran tubuh 6-9 cm dianggap betina. Pemijahan berlangsung menggunakan pemijahan alami, jumlah telur yang didapatkan 1.162 butir dan telur yang dibuahi 886 butir. Derajat pembuahan sebesar 76% dan Derajat Penetasan 100%. Manajemen pakan yang diberikan yaitu pelet ukuran 1 mm sebagai pakan utama dan arthemia sebagai pakan alami tambahan. Penyakit yang menyerang ikan badut selama kegiatan berlangsung tidak ada, namun menurut Laporan Hasil Uji No.234/I/LHU/BPBL-B/X/2019 hama atau penyakit yang menyerang ikan badut adalah Cryptocarion irritans dan Vibrio sp.
