Effectiveness of Octopus (Octopus sp.) Ink Exctract on the Growth of Catfish (Clarias sp.) Infected with Aeromonas hydrophila

One material that can be used to improve feed quality is octopus ink. Octopus ink can serve as an alternative nutrient source to optimize catfish growth. Ink produced by cephalopods such as squid, octopus, and cuttlefish contains various components, including fat, protein, ash, and carbohydrates. The aim of this research is to determine the effect of administering octopus ink extract (Octopus sp.) on the growth of catfish (Clarias sp.) infected with Aeromonas hydrophila bacteria.
