Development of a Scalable Extraction Process for Anthocyanins of Haskap Berry (<i>Lonicera caerulea</i>) by Damith Costa, H.P. Vasantha Rupasinghe

“…In this investigation, a response surface methodology was applied to optimize the anhydrous ethanol-based extraction parameters to obtain the maximum yield of anthocyanins from haskap berry and to compare the recovery of anthocyanins from different extraction methods. The central composite design was employed to study the effect of three independent variables (X_A = ultrasonic bath power, X_B = extraction temperature, and X_C = extraction time) which were found to significantly affect the response variable total anthocyanin content (TAC) and fit to the second-order polynomial model. …”

Depletion Estimation, Stock–Recruitment Relationships, and Interpretation of Biomass Reference Points by Mark N. Maunder, Kevin R. Piner

“…Therefore, estimates of depletion are particularly sensitive to uncertainty in the biological processes related to natural mortality and the stock–recruitment relationship and to growth when length composition data are used. In addition, depletion-based reference points are highly dependent on the stock–recruitment relationship and need to account for recruitment variability, particularly autocorrelation, trends, and regime shifts. …”
