Appropriate binders have not yet been determined in pellet feed for amberjack Seriola dumerili juveniles. This study aimed to assess the influence of binders (activated gluten [AG], guar gum [GG], and carboxymethylcellulose [CMC]) on growth, feed ingestion, gastric emptying time (GET), digestibility, intestinal histology, body composition, and blood chemical constituents of amberjack juvenile. Dry pellets bound by supplementing different binders (3% AG, 2.5% AG combined with 0.5% GG [AG + GG], and 3% CMC) were fed to fish (mean body weight ± SD = 52.5 ± 0.6 g) for 30 days. After feeding, fish fed the AG diet exhibited growth, protein and dry matter digestibility, and feed utilization levels significantly (p < .05) higher than those of fish fed the AG + GG and CMC diets. Moreover, GET in fish fed the AG + GG and CMC diets were slower than those from fish in the AG group. These responses appeared to be associated with the viscosity of binders and diets. In fish fed the AG + GG and CMC diets, several blood indices were significantly (p < .05) lower than those in fish fed the AG diet. These results suggest that AG is a candidate binder in pellet feed for amberjack juvenile.

Aim Dietary self‐care for patients with type 2 diabetes can be improved with family support. The purpose of this study was to develop a scale to assess family support for diet therapy for male workers with type 2 diabetes and to examine its reliability and validity. Methods In this cross‐sectional study, we collected data from 110 Japanese male workers with type 2 diabetes. Data were analyzed using exploratory factor analysis, reliability testing, and validity testing. Results The resultant Family Support Scale for Diet Therapy for Male Workers (FSS‐DMW) with type 2 diabetes consisted of 31 items and a six‐factor structure. The six factors explained 72.9% of the variance, and Cronbach's alpha for the total scale was .964. The scale correlated as expected with the Social Support Scale for Chronic Illness and the dietary subscale of the Japanese version of the Summary of Diabetes Self‐Care Activities Measure. Conclusion The FSS‐DMW is a reliable and valid measure which can be used to assess family support for diet therapy for male workers with type 2 diabetes and has the potential to be used as a clinical instrument for family guidance.
