Abstract

Pulau Bangka dan Belitung memiliki potensi ikan lokal yang potensial. Salah satunya adalah Osteochilus spilurus yang dikenal sebagai Ikan Cempedik dan bernilai ekonomis penting di pulau Belitung, khususnya Belitung Timur. Universitas Bangka Belitung, Pemerintah daerah Belitung Timur, dan Balai Riset Perikanan Budidaya Air Tawar Bogor telah melakukan berbagai riset terhadap O. spilurus dalam upaya mendomestikasikannya menjadi komoditas akuakultur. Riset perlu didisemenasikan sebagai capaian pengembangan potensi ikan lokal Bangka Belitung sehingga dilakukan forum diskusi online dalam webinar. Webinar dihadiri 206 peserta dari Medan hingga Ambon dan Kupang. Penyampaian materi diikuti dengan diskusi melalui tanya jawab tertulis maupun visual, dan diakhiri kuis untuk mengetahui pemahaman peserta webinar. Antusiasme peserta bertanya dan kemampuan menjawab pertanyaan menjadi tolok ukur bahwa pengetahuan tentang pengembangan potensi ikan lokal telah diterima oleh peserta. Pengetahuan ini diharapkan dapat menjadi landasan pengambilan keputusan peserta saat dihadapkan dengan permasalahan dan potensi ikan lokal di daerahnya.

Abstract

Fish eggs semah in cultivating on average only hatch of 67%, so still far stated well and need to do a proper egg incubation technique to increase the degree of hatching. Efforts are being made at other hatcheries as Catfish is using the technique of egg incubation method of stagnant water and MacDonald jars, but this system still has flaws, that can lead to poor water quality (stagnant water) and the presence of abnormal larvae (Mac Donald jars). In this study, the technique of egg incubation is carried out using a multilevel system tray modification. The results of the use of multilevel system tray in Aquarium shows very different real power against egg hatch (HR) fish semah, whereas against an increase in the degree of abnormality of fish larvae semah influence is relatively the same.The use of 3-floor tray (A3), can enhance degrees most high 89.19% hatching, larval fish and the degree of abnormality 1.63%.Key words : System tray multilevel, tetas power eggs (HR), the degree of abnormality, Tor douronensis

Abstract

Two experiments were conducted in the IRD-Gamet Laboratory, Montpellier, France. The first was to evaluate the recovery of Heterobranchus longifilis female gonad after induced ovulation, under tropical condition. Oocyte diameter was used as indicator of the recovery rate following by induced breeding, hatching rate and abnormality of larvae. The results showed that the recovery was about 28 to 35 days after ovulation. The second was carried out to improve the milt production by hormone treatments. Volume of intratesticular sperm and the number of spermatozoa were observed. The results indicated that the treatmens did not prove any significant difference.
