Effects of Different Habitat Space on Growth Performance and Nutritional Composition of Swimming Crabs (Portunus trituberculatus)

Habitat space is crucial for animals. This experiment explored the effect of four different farming acreages (0.5 m2, 1 m2, 10 m2, and 100 m2) on survival rate, growth performance, and muscle nutrition composition of swimming crabs (Portunus trituberculatus) at the farming density of 2 ind/m2. The r...

Zusammenfassung:	Habitat space is crucial for animals. This experiment explored the effect of four different farming acreages (0.5 m2, 1 m2, 10 m2, and 100 m2) on survival rate, growth performance, and muscle nutrition composition of swimming crabs (Portunus trituberculatus) at the farming density of 2 ind/m2. The results showed that the survival rate of the crabs that live in the 10 m2 group and live in 0.5 m2 alone had the highest survival rate of 20.50% and 20%, better than the 1 m2 group and the 100 m2 group with the lowest of 12.00% and 13% (P0.05). The crude lipid content was the highest in 1 m2, which was significantly higher than in 0.5 m2 (P
