Transportation of Blackmoor (Carassius auratus) Goldfish Variety with Low-Temperature Treatment at Different Durations

Abstract

This research aims to analyze the induction time and recovery time of Blackmoor Goldfish (Carrasius auratus) with different low temperatures as a transportation method, to find out how to handle it with a proper temperature reduction in its transportation, and to find out the optimum time period in its transportation This study was carried out from November 2020 to February 2021 in the Ciparanje wet laboratory, Faculty of Fisheries and Marine Sciences, Universitas Padjadjaran. This research was conducted experimentally using the Factorial Randomized Block Design (FRBD) which consisted of two factors, namely four levels of treatment (12 °C, 16 °C, 20 °C, and 24°C (control)) and three levels of transportation duration (3, 5, and 7 hours) which were repeated three times. This research uses a closed transportation system. The research results showed that the low-temperature treatment of 16°C and a transportation duration of 3 hours was the best treatment with an induction time of 02:37, recovery time of 07:13, and having a post-transportation survival rate of 90% and post-maintenance for 7 days of 85 %. The DO parameter is ±7.53 mg/L, pH is ± 7.38 and ammonia is ±0.0016 mg/L.
