Study on Single Species One Sex Age-structured Fish Population Model with Restricted Harvesting | Chapter 6 | Current Topics on Mathematics and Computer Science Vol. 7

Under age-dependent harvesting conditions, a discrete age-structured Bernardelli, Lewis, and Leslie (BLL) population model for a single species is created. Harvesting takes place here following an early stage in which the species does not grow much. Its rate is proportional to the available bio-mass (number of species) of different age groups, and it declines with the age of the species when a monotonic decreasing catch per unit effort parameter is used. The modified Leslie matrix is calculated for the current models. The ratio of population densities with regard to time is used to investigate the system's stability. This type of research is critical in population biology because it provides insight into the species' future biomass and long-term viability.
