Abstract

Fishmeal is the primary raw material in fish feed formulations as a source of protein raw materials. Its limited availability and fluctuating prices encourage using alternative protein sources, one of which is worm meal. This study compare the use of fish meal and worm meal in catfish (Clarias sp.) feed the hepatosomatic index (HSI), blood glucose levels, and gastric emptying rate. The research was conducted using an experimental method with two treatments: fishmeal-based and worm meal-based. HSI data obtained were analyzed by independent-sample T-test analysis, while data on blood glucose levels and gastric emptying rate were analyzed descriptively. The results showed no significant difference (p>0.05) between treatments on hepatosomatic index. Fluctuations in blood glucose levels are also in line with the rate of gastric emptying, which is not too different between treatments. This study showed that worm meal has the potential to be used as an alternative to fish meal in catfish feed without causing physiological changes.

Abstract

The use of simple filter media can reduce organic waste materials in Nile tilapia aquaculture systems. The performance of biofilters is strongly influenced by the type of media used, depending on their characteristics in supporting biofilm formation. This study aimed to analyze the effectiveness of bioball and pumice as biofilter media on water quality and the growth performance of Nile tilapia (Oreochromis niloticus) in a recirculating aquaculture system. The research was conducted from October to November 2024 at the Integrated Farming Laboratory, PSDKU Universitas Brawijaya Kediri, using an experimental method. Two treatments were applied, namely bioball (P1) and pumice (P2), with observations on water quality parameters including temperature, pH, dissolved oxygen (DO), Total Organic Matter (TOM), alkalinity, ammonia, nitrate, and phosphate, as well as fish growth parameters including absolute growth, specific growth rate (SGR), and survival rate (SR). Data were analyzed using the Independent Sample T-Test, while alkalinity, absolute growth, and survival rate were analyzed using the non-parametric Mann–Whitney U test. The results showed that the use of biofilter media did not have a significant effect (p>0.05) on all water quality parameters, but showed a significant difference in absolute growth. Pumice media demonstrated better performance in increasing DO (5.6–10.3 mg/L) and reducing organic matter with a removal efficiency of 33–70% and ammonia up to 94%. In terms of growth performance, the pumice treatment produced higher values of absolute growth (2.52 ± 0.26 g), SGR (2.53 ± 0.18%/day), and SR (86.7 ± 4.7%) compared to bioball. Therefore, pumice has the potential to be recommended as a promising biofilter medium for improving water quality and growth performance of Nile tilapia in recirculating aquaculture systems.
