Abstract

The purpose of this study was to identify diseases in gariang fish in the Lubuk larangan river. The research locations used were Nagari Guguak Kuranji Hilir, Sungai Limau District, Nagari Sikucur Barat, District V Koto Kampung, Nagari Lareh Nan Panjang Selatan, District VII Koto Sungai Sariak and Nagari Sicincin, District 2 x 11, six research environments were carried out from September to December 2021. Fish samples were tested in the laboratory at the Padang Fisheries Product Quarantine and Quality Control Center to calculate the parasite prevalence. The results of this study are the type of Saprolegnia sp was found at all lubuk larangan sample point locations with the highest prevalence of 30%. Dactylogyrus sp and Trichodina sp also continued to attack gariang at all sample points with the second highest prevalence, namely 15%. Aeromonas caviae was found at 3 points, sikucur barat, lareh nan panjang selatan and sicincin 2x 11 enam lingkung with a prevalence of 10%. Plesiomonas shigelloides was found in 2 locations, guguak kuranji hilir and Sicincin 2x11 enam lingkung, while Aeromonas sobria attacked 3 sample locations, guguak kuranji hilir, 2x11 enam lingkung and lareh nan panjang selatan with a prevalence rate of 8%. Hafnia alvei, Actinobacillus linieressi and Argulus sp prevalence rate of 5%. The highest prevalence at 30% indicates that the level of parasitic attack is generally with the usual infection. The results of Intensity of Ind/parasites were found as many as 28 at all sample points of the lubuk larangan river, the most commonly found in 2 x 11 enam lingkung, parasites and the least in sikucur barat with an intensity of 6. For Ind/tail intensity at 4 sampling points gariang fish (Tor tambroides) at 2.8 which means a low infection rate.
