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

Stock assessment and management implications of sailfin sandfish (Arctoscopus japonicus) caught by multiple fishing gears with different selectivity in Korean waters [PDF]
PeerJThe yield per recruit (YPR) model developed by Berverton & Holt in 1957 is widely used to determine the optimal age at first capture (tc) and optimal fishing intensity (F0.1) for the sustainable use of fish stocks.

Demographics and Yield–Per–Recruit Assessment of the Vulnerable Spiny Lobster Palinurus elephas in the Azores—Implications for Conservation and Fisheries Management [PDF]
Biology, 2022 The spiny lobster Palinurus elephas has been intensively harvested across its range and is generally considered overfished, with global landings declining sharply from an average of 820 t in 1960–79 to 385 t in 2000–19.

Sex-specific yield per recruit and spawning stock biomass per recruit for the swordfish, Xiphias gladius, in the waters around Taiwan [PDF]
Fisheries Research, 2005 Abstract Sex-specific yield per recruit and spawning stock biomass per-recruit analyses were conducted to evaluate the population status of swordfish in the waters around Taiwan. Estimates of the total mortality rate, obtained from length composition data by catch-curve analysis, are on the order of 0.30 year−1 for females and 0.35 year−1 for males ...

Local sensitivity of per-recruit fishing mortality reference points
Journal of Biological Dynamics, 2016 We study the sensitivity of fishery management per-recruit harvest rates which may be part of a quantitative harvest strategy designed to achieve some objective for catch or population size.
