Budidaya ikan Koi semakin berkembang karena stabilnya nilai jual dan jumlah penggemarnya. Salah satu daerahyang secara geografis memiliki kesesuaian untuk mengembangkan budidaya ikan Koi adalah Blitar. Produksi ikan Koi yang dihasilkan oleh pembudidaya di Blitar terkenal memiliki kualitas yang tidak kalah dibandingkan dengan Koi yang yang berasal dari negara lain sehingga konsumennya tersebar di seluruh dunia. Kondisi ini menuntut para pembudidaya untuk lebih baik lagi mengembangkan sistem budidaya untuk mempertahankan kualitas produksinya. Berdasarkan hasil survei dan komunikasi dengan UKM Garum Koi Community(GKC) di Blitar yang bergerak dalam bidang ini masalah yang sering dihadapi adalah tingginya kematian ikan yang disebabkan oleh penyakit. Penyakit ini diduga bersumber dari menurunnya kualitas lingkungan yang tidak tertangani secara baik sehingga menyebabkan penurunan kekebalan tubuh ikan Koi. Tujuan dari kegiatan ini adalah untuk memberikan edukasi dan pendampingan tentang upaya pencegahan kematian yang terjadi pada ikan Koi melalui pemberian imunostimulan berbahan alami dan kontrol kualitas air menggunakan alat yang berbasis internet kepada pembudidaya ikan Koi di Blitar. penggunaan bahan dan alat serta pemberian bantuan bahan imunostimulan dan alat detektor kualitas air berbasis internet
Environmental pollution could directly reduce water quality for shrimp cultivation. This aims of this research were to determine how the environmental quality, shrimp population and genetic characteristics of shrimp that live in polluted waters in shrimp ponds in East Java associated with WSSV disease that often attacks on cultivated shrimp. The method used was a descriptive exploratory. Data was collected by observation and interview with farmers on disease history. Water was sampled for water quality study and characterize its suitability for shrimp cultivations. Shrimps were also sampled for morphological and genetical study for its susceptibility of WSSV. All samples were taken every week during shrimp cultivation in Malang and Gresik. Morphological study using scoring method to determine the disease stages on shrimp, while for genetical study using specific primer for ICP11 for WSSV detection, since ICP 11 was expressed when WSSV infection was occured. Samples were taken from 2 shrimp ponds in South Malang and Gresik. The result showed that the overall water quality was good, except for NO2 and TOM in both seawater shrimp ponds which higher than the freshwater/estuary shrimp ponds. Light infections of WSSV were detected in all seawater ponds both in morphology and genetics. However, in the freshwater/ estuary pond only shrimps from freshwater/ estuary Gresik which showing light WSSV infection genetically, but not in the morphological signs. Early disease detection is important to control the disease spread.
The increasing number of Koi ornamental fish interested around the world, this fish farming business is increasingly developing. Blitar is one of the geographically suitable areas to develop Koi fish farming. The resulting production has a quality of Koi better than from other countries. Cultivation models and techniques developed are also increasingly advanced, but often cultivators have disease problems stemming from decreasing environmental quality that are not handled early. This attracted the Brawijaya University Doctoral community service team to help find solutions to these problems.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
