Effectiveness of Different Bubble Size of Aeration to Survival and Growth Rate of Pangas Catfish Larvae, Pangasius nasutus

This research was conducted at the fish fry center in Tasikmalaya City, Jl. Kadupugur No. 42 Kota Tasikmalaya. The research was done from November 2019 until February 2020. This research is carried out to determine the survival rate and growth of pangas catfish larvae up to the age of 22 days. Old with different bubble sizes of aeration stone the pangas catfish larvae used was 600 fingerlings that are spread evenly into 12 aquariums with four treatments each replicated three times using a completely randomized design (CRD). The parameters observed are survival rate, growth rate (weight and length), and water quality. The results showed that the aquarium with aerator ASB05 is the most effective treatment in influencing the productivity of pangas catfish larvae. The survival rate is 99.3%, the absolute length is 14.81mm and the absolute weight is 40.1 g. whereas the water quality of each treatment is still within the SNI quality standard (2000) with dissolved oxygen level is 5.40 mg/L.
