Effect of density and shelter on growth, physiology, and biochemical composition of the crayfish Cambarellus montezumae

We analyzed the combined effects of population density and presence or absence of shelters on growth and physiological performance of the crayfish Cambarellus montezumae. Three different densities-64, 144, and 208 crayfish per m 2 -with and without shelters were used. Growth; survival; metabolic rat...

Summary:We analyzed the combined effects of population density and presence or absence of shelters on growth and physiological performance of the crayfish Cambarellus montezumae. Three different densities-64, 144, and 208 crayfish per m 2 -with and without shelters were used. Growth; survival; metabolic rate; tissue glucose; and total lipid, triglyceride, nitrogen, and energy content were measured. Animals stocked at 64 and 144 per m 2 with shelter reached the highest body weight; those in groups without shelter had elevated levels of glucose (p < .05). Animals stocked at 144 per m 2 retained the most nitrogen and energy (p < .05). Overall, the combination of medium density with shelters produced the best performance.
