Respiratory metabolism and growth of atlantic salmon in relation to various levels of routine activity
Studies on the respiratory metabolism and growth of young Atlantic salmon (132 - 475 g) in seawater at 8. SOC have been conducted. The experiments were performed in the laboratory using five "growth metabolism" tanks. The average metabolic rate at swimming speeds from 5-25 cm/ sec. wer e d...
