The striped catfish (Pangasianodon hypophthalmus) is one of the freshwater fish commodities with high economic value and is widely favored by local communities. Feed is one of the most important factors influencing the growth and survival of aquaculture organisms, accounting for approximately 60–70% of total production costs. To reduce feed production expenses, it is advisable to utilize loca…
Asian redtail catfish (Hemibagrus nemurus) is widely found in Riau waters and has high aquaculture potential. Larvae are usually fed tubifex worms, but their limited availability requires alternatives. Commercial feed PF-0 can be used in paste form, though it is less digestible for larvae. Fermentation and ginger powder supplementation may improve feed utilization. This study aimed to determine…
Pasta feed is one of the alternative replacement feed naturally occurring in the cultivation of Asian redtail catfish (H. nemurus) larvae. However, pasta feed is not yet able to completely replace the silk worm, and enrichment feed pasta with oils from mesenteric waste catfish, expected to improve the performance of pasta feed. The aim of this research was to determine the effect of enriching f…
Catfish is one type of freshwater fish that is cultivated and is a food ingredient for Indonesian people, therefore it is necessary to carry out cultivation engineering that can increase fish growth to meet the needs of the community.
