Assessing the effect of feeding regimens on their overall growth requires grow-out trials and a subsequent inefficient use of time and money. The growth hormone (GH)/insulin-like growth factor-1 (IGF-1) axis regulates growth based upon environmental factors such as feed intake in many teleost fish species. In order to increase the efficiency of aquaculture, the components of the GH/IGF-1 axis might be used as endocrine biomarkers to evaluate instantaneous growth rate. The goal of this study was to better understand the effects of feeding regimen on the regulation of growth in channel catfish. Accelerated growth during re-feeding periods after fasting is of particular interest. These periods, termed compensatory growth (CG) periods, have been observed in several teleost fishes. To study this, mRNA expression of GH/IGF-1 axis components was examined in the liver, skeletal muscle and pituitary of channel catfish during two weeks of fasting and one week of re-feeding with a control group of animals fed daily. In addition, hepatosomatic index (HSI) and condition factor (CF) were calculated for each fish. CF data suggests CG after only a week of re-feeding. Fasting induced a significant decrease (P<0.05) in HSI, which returned to normal after re-feeding. Fasting induced a significant increase in muscular ghr-1 (P<0.01) and a significant decrease in muscular igf-1 (P<0.001). Re-feeding induced a significant increase in hepatic igf-1 (P<0.001), igfbp-5a (P<0.01), igfr-1a (P<0.001), and ghr-1 (P<0.01) and in muscular igf-2 (P<0.01), igfbp-1 (P<0.001), igfbp-2 (P<0.01), igfbp-5a (P<0.05), and igfr-1a (P<0.05). Results indicate that the GH/IGF-1 axis is highly sensitive to re-feeding in channel catfish and that CG can be induced.

Interprofessional collaboration allows for a large amount of progress to be made throughout the client-centered world, as well as the healthcare world. The need for implementation of interprofessional education is higher than ever due to the amount of people involved in comorbid injuries and illnesses. The process of collaboration may be strenuous at times, but the benefits ultimately outweigh those factors. The collaborative world will open up various opportunities and ideas through the collegiate and professional world. When others are able to see what collaboration can do, the more they will want to be involved. Occupational therapy is a collaborative field, and the need for occupational therapists is only growing. The need for wanting to collaborate is needed, and that number can only rise if the awareness of collaboration is reached. Interprofessional education should be taught in all universities and have developed framework with the amount of resources that are available in today’s society. This information in this paper expresses the need and awareness of interprofessional collaboration and education in today’s world
