Abstract

The purposes of this study were to observe and analyze the water level variations of the culture media that were optimal for egg hatchability and larval survival of kelabau fish kept in aquarium. This study was conducted in the Freshwater Aquaculture Development Centre (FADC) Banjar Regency in August 2015. The method used in this study was experimental, using a completely randomized design with 3 treatments (A = water level of 15 cm/aquarium), (B = water level of 25 cm/aquarium), (C = water level of 35 cm/aquarium) and 3 replications. The parameters measured in this study were the egg hatchability, survival rate, relative growth rate, and water quality (temperature, pH, DO, Ammonia). Data were analyzed by Anova and the differences between treatments were tested with Duncan test. The results showed that the water level very significantly affected the egg hatchability with the highest value in B (38.29%) followed by C (31.83%) and A (14.04%). The highest survival rate was in C (79.73%) followed by B (65.10%) and A (21.83%). The relative growth rate had not significant effect with the average results between all treatments (104.92 – 117.27%). The water quality of the culture media was still good to support the growth and survival of fish.

Abstract

The research aimed to analyze the interaction, variation of stocking densities and effect of different types of feed on growth and survival of catfish (Clarias gariepinus) seeds in the plastic ponds and their interaction. The research was carried out in West Kotawaringin, Pangkalan Bun of Central Kalimantan from May to July 2017. A completely randomized design with two-factor experiment (stocking density and types of feed) were applied in the study, namely 100 seeds/m3 (treatment A1), 150 seeds/m3 (treatment A2), 100 % commercial pellet (treatment B1), 100 % chicken intestine (treatment B2), and 50 % commercial pellet and 50 % chicken intestine (treatment B3). Catfish with initial body weight 1 g were reared in the plastic pond (1x1x1x1 m3) for 60 days. The results showed that individual weight gain was range 35,22 to 60,12 g, the best treatment A2B3. Survival rate ranged from 40,00 – 76,66%, the best treatment A1B2.
