Survival, growth performance, length–weight relationship and biochemical composition of cultured rainbow crab (Cardisoma armatum) fed plant and animal protein diets

Abstract

Paper summary generated by OpenAI: This study investigates the survival, growth performance, length-weight relationship, and biochemical composition of cultured rainbow crabs (Cardisoma armatum) fed diets comprising plant and animal proteins. A total of 90 crabs were allocated into three treatment groups and cultured for 16 weeks. Results indicated that crabs fed an animal source diet exhibited the highest growth rates, while those on a complete source diet showed the best survival rates. The study also revealed a negative allometric growth pattern and highlighted the influence of dietary composition on the biochemical properties of the crabs, emphasizing the potential of C. armatum as a sustainable aquaculture resource in addressing nutritional deficiencies in coastal regions.
