Mukti RC, Artika AD, Napitupulu EB, Saputra MI, Anila Y, Maslamia A, Juniarti H, Dianda A. 2022. Different feed sources on the brightness of golfish (Carrasius auratus). In : Herlinda S et al. (Eds.), Prosiding Seminar Nasional Lahan Suboptimal ke-10 Tahun 2022, Palembang 27 Oktober 2022. pp. 809-815.  Palembang: Penerbit & Percetakan Universitas Sriwijaya (UNSRI).Goldfish often find problems in ornamental fish cultivation, namely in terms of color and morphology of ornamental fish produced in Indonesia which are very unattractive, bright and bright fish colors are one of the main attractions of ornamental fish in determining their selling value, to determine the growth rate, increase in color brightness and carotenoid content of goldfish (Carrasius auratus) after being given additional feed in the form of indigofera flour, carrot flour and water hyacinth flour. The method used is a literature study by comparing the three types of feed, namely indigofera flour, carrot flour and water hyacinth flour. The results showed that several sources of -carotene in the feed gave different results in increasing the color brightness of goldfish. The 5% dose of indigofera flour and carrot flour was the best dose for the color brightness of goldfish, while the additional dose of water hyacinth flour given was the 300 g dose that was the best dose to support the color quality of goldfish (Carassius auratus). So, with the results of the three types there is a significant difference in the brightness level of goldfish color.

Abstract

Green catfish (H. nemurus) is a type of freshwater fish that has the potential to be cultivated. Green catfish cultivation needs to be supported by ideal environmental conditions so as to produce maximum survival rate and growth. One environmental technique that can be used is water level, because the higher the water column the more energy it will uses to move and can affect the growth of green catfish fry. This research aimed to determine the best water level for survival rate and growth of green catfish fry. This research was carried out in January-February 2024 at the Fisheries Basic Laboratory, Aquaculture Study Program, Fisheries Departement, Agriculture Faculty, Universitas Sriwijaya. This research used a completely randomized design (CRD) consisting of 4 treatments and 3 replication, namely P1 with a water level of 6 cm, P2 with a water level of 12 cm, P3 with a water level of 18 cm and P4 with a water level of 24 cm. This research was carried out for 30 days. The research results showed that differences in water level a significant effect on survival rate, growth, feed efficiency and oxygen consumption level but have no significant effect on blood glucose level. The results showed that the best treatment namely P3 resulted in absolute weight growth of 3.62 g, absolute length growth of 3.60 cm, feed efficiency of 80.00%, survival of 96.30%, blood glucose level of 15,00 mg dL-1 and oxygen consumption level of 1.12 mg O2 g-1 hours-1. The  water quality values for all treatments still support the survival rate of green catfish fry.Keywords: Green Catfish; Fish Growth; Survival Rate; Water Level
