“…The concentration of boron in the initial feed and the water was determined by the curcumin method spectrophotometrically (Dyrssen et al 1972). A 5 g feed was crushed and extracted with 10 mL of distilled water boiling for 15 minutes under reflux and was filtered as quickly as possible (Porter et al 1981). The absorbance of the boric acid in the obtained solutions and the water samples with three replicates based on complexing with curcumin was measured at 540 nm.…”

The effects of different levels of boron supplementation to feed on the growth parameters of rainbow trout (Oncorhynchus mykiss) were investigated for the first time using four diet variations (0.01%, 0.05%, 0.10%, and 0.20% of boron in feed) in addition to a control diet (without boron). After 120 days of feeding, the final weight (FW), weight gain, condition factor, feed intake, feed conversion rates, specific growth rate, protein efficiency ratio, survival rates, economic conversion rate, and economic profit index were calculated for each treatment and compared with the control as growth parameters. The initial weight was 17.89 ± 1.12 g; at the end of feeding, the FWs were determined as 89.91 ± 2.11 g for the control and 90.56 ± 1.34 g, 99.21 ± 3.76 g, 88.14 ± 2.43 g, and 78.74 ± 1.47 g for 0.01%, 0.05%, 0.10%, and 0.20% of boron feed treatments, respectively. The results of this study show that feeding rainbow trout with 0.05% boron-supplemented feed stimulates the growth parameters, but 0.20% of boron supplementation inhibits the growth of rainbow trout.

“…The spectrophotometric technique using a colorimetric reaction with azomethine-H has been the most extensively tested B determination method for soil and plant samples (Ogner, 1980;Parker & Gardner, 1981;Porter et al, 1981;Lohse, 1982;Garcia et al, 1985;Lee et al, 1987;Chen et al, 1989;Kaplan et al, 1990;Banuelos et al, 1992;Campana et al, 1992;Nogueira et al, 1993). In this type of determination, hot water and 0.5 M HCl have commonly been used as extractants, both for acidic and alkaline soils.…”
