From: Cost-benefit analysis of aquaculture breeding programs
Net present value (\(NPV\)) for the optimum number of selection candidates in the four breeding programs. a As function of length of the time horizon for a production of 5000 tons/year, b as function of production output for a time horizon of 10 years. Blue line: baseline breeding program, red dotted line: breeding program with annual multiplier tier replacement, green dashed line: breeding program with priority on improvement of the multiplier tier, violet dashed line: breeding program without a multiplier tier
