A comparison study of age- and length-structured yield-per-recruit models [PDF]

Aquatic Living Resources, 1997
Les modeles de rendement par recrue sont communement utilises pour orienter la gestion et pour estimer les points de reference biologique, F 0.1 ou F MAX . Bien que ces modeles soient habituellement structures en âge, leurs parametres sont plus directement lies a la taille qu'a l'âge.

Growth, mortality and yield-per-recruit of Copadichromis likomae (Cichlidae) in Lake Niassa, Mozambique [PDF]

, 1992
Analysis of the length-frequency data on Copadichromis likomae (Cichlidae) from Lake Niassa, Mozambique, suggests an asymptotic length of SL∞=14 cm associated with a K value of 0.93 yearˉ¹. Total and natural mortalities were estimated as 3.2 yearˉ¹ and 1.9 yearˉ¹, respectively. Yield-per-recruit analysis suggests that E=0.36 in this fishery.

Yield-per-Recruit, Utility-per-Recruit, and Relative Biomass of 21 Exploited Fish Species in China's Coastal Seas

Frontiers in Marine Science, 2019
Based on growth and related fishery parameters, three approaches, yield-per-recruit (Y/R), utility-per-recruit (U/R) analyses, and relative biomass (B/B0) analyses were applied to 21 economically important, trawl-caught species in China's coastal seas to
