SIAMESE FIGHTING FISH (Betta Sp.) FAINTING TECHNIQUES IN ONE TRANSPORTATION CONTAINER USING COLD TEMPERATURE METHOD

Fisheries Aquaculture

The production of ornamental fish is increasing every year. Siamese fighting fish is one type of ornamental fish that can exceed the national target for ornamental fish production. Anesthesia using low temperatures can minimize the metabolism of siamese fighting fish without leaving residues that can harm the fish. This study aims to analyze the most optimal fainting technique, duration of transportation, and density for transportation of siamese fighting fish in one container. This research was conducted during August 2021 – September 2021 in Rancaekek District, Bandung Regency and Ciparanje Wet Laboratory, Padjadjaran University, Sumedang Regency, West Java. This study used a 2-factor randomized block design method with 3 replications. The factors used are; fainting technique factors consisting of induction techniques and direct techniques and transportation duration factors; consists of 2 hours, 4 hours, and 6 hours. The density factor was analyzed descriptively with the assumption that fish would not pile up on each other in the transportation container; which consists of 1 tail, 3 tails, 6 tails, and 9 tails. Parameters observed were survival rate and water quality. The results of the ANOVA test showed that the results of all treatments were significantly different. The treatment that had the best survival rate was using the induction fainting technique with a transportation duration of 4 hours, up to a density of 6 fish in one transportation container with temperatures from 19.45 to 21.45 oC, DO from 6.02 to 6.20 O2 mg/l, pH from 5.89 to 6.11 and amonia from 0.0014 to 0.0025 mg/l
