Package: fb4package Type: Package Title: 'Fish Bioenergetics 4.0' Model Implementation with High-Performance 'TMB' Backend Version: 2.1.1 Authors@R: c( person( "Hans", "Ttito", email = "kvttitos@gmail.com", role = c("aut", "cre") ) ) Description: An implementation of the 'Fish Bioenergetics 4.0' framework described in Deslauriers et al. (2017) . Provides automated parameter optimization, multi-prey diet modeling, and comprehensive energy budget simulations for fisheries research and aquaculture applications. An optional 'TMB' (Template Model Builder) backend delivers 10-50x speedup in maximum likelihood estimation while maintaining full backward compatibility. Includes species-specific parameter databases and tools for modeling fish growth, consumption, and metabolism under varying environmental conditions.
