alat laboratorium air yang cocok untuk mendeteksi penyakit udang yakni Infectious Myonecrosis Virus (IMNV) adalah virus yang umum menyerang udang putih (Litopenaeus vannamei) dalam industri budidaya udang di dunia. Di Indonesia, penyakit myonecrosis pertama kali diketahui terjadi pada udang putih dari pertambakan di Situbondo, Jawa Timur, pada tahun 2006 dengan prevalensi 11.11% dan gejala klinis serupa dengan kejadian wabah myonecrosis di Brazil pada tahun 2002.
Untuk mencegah IMNV, perlu dilakukan perbaikan lingkungan mikro dengan menjaga kualitas air agar tetap terjaga. Pembudidaya harus memhami bahwa kolam budidaya merupakan satu kesatuan ekosistem perairan. Di dalamnya selain terdapat udang juga melibatkan banyak parameter kimia, fisika, biologi dengan beragam organisme yang saling berinteraksi secara simbiosis mutualisme, parasitisme, dan komensalisme dalam lingkup rantai makanan atau siklus kehidupan.
Pengukuran parameter kualitas air dapat dilakukan setiap hari untuk parameter fisika karena kecenderungan perubahan terjadi setiap hari, sedangkan parameter kimia dan biologi dapat dilakukan minimal seminggu sekali, hal ini dilakukan untuk menghemat anggaran dalam pengecekan kualitas air.
