        In this study, we investigated the growth of striped mullet (Mugil cephalus), Yesso scallop (Patinopecten yessoensis) and kelp (Saccharina japonica) farmed under the IMTA (integrated multi-trophic aquaculture) system developed by national institute of fisheries science (NIFS). The farmed striped mullets grew from an initial length and weight of 152.5±12.1 and 41.6±7.8 g in October 2013 to 154.2±5.6 and 47.5±8.6 g in November, 160.2±8.7 and 55.9±9.1 g in December and 168.4±9.6 and 58.4±8.7 g in January. The fish continued to grow and reached 190.2±9.4 in length and 87.5±8.9 g in weight in April and 256.4±9.7 and 156.7±6.7 g in October 2014. The daily growth rate (DGR) for total fish length was 0.015 0.1 /day during the periods of fast growth and attained 0.038 0.1 /day during February March. The kelp grew from an initial blade length and wet weight of 1.19±0.2 and 0.0028±0.0012 g in January 2014 to 3.3±0.8 and 2.5±0.9 g in February and 126.5±11.6 and 107.4±22.6 g in March, after which, erosion occurred and slowed the growth. The DGRs for kelp length ranged 0.03 1.9 /day in January 2014 and increased to 0.88 1.9 /day during March April. Increasing water temperatures beginning in April lowered the DGR to 0.03 /day. Yesso scallops grew from an initial shell length, shell height and wet weight of 11.83±0.6 , 12.68±0.7 and in September 2013 to 19.9±2.5 , 20.8±2.6 and 0.9±0.04 g in November 2013. They continued to grow to 45.91±0.71 in shell length, 42.55±0.8 in shell height and 12.7±1.3 g in wet weight by May 2014 and 60.2±2.51 , 554.6±2.61 and 24±2.70 g by October 2014. The DGRs for shell length of Yesso scallop ranged from 0.02 to 0.256 /day with higher values of 0.256 0.27 /day during November December 2013 and March April 2014.
