The population parameters of Encrasicholina punctifer (Buccaneer anchovy) from commercial fishery in the Persian Gulf and Oman Sea coastal waters were studied from October 2014 to September 2015. A total of 13951 length-frequency data collected monthly by pair-boat purse seine and beach seine methods. The asymptotic length (L∞) and Von Bertalanffy growth function (K) were 11.5 cm and K = 1.4 pe...

Changes over time in age, sex, and length-at-age of returning Pacific salmon have been widely observed, suggesting concurrent declines per capita reproductive output. Thus, assessment models assuming stationary output may inaccurately estimate biological reference points that inform harvest policies. We extended age-structured state-space spawner–recruit to accommodate demographic trends fisher...
Deterioration of reproductive traits with age is observed in an increasing number of species. Although such deterioration is often attributed to reproductive senescence, a within-individual decline in reproductive success with age, few studies on wild animals have focused on direct fitness measures while accounting for selective disappearance and terminal effects, and to our knowledge none have...
OBJECTIVE To report the number of participants needed to recruit per baby born to trial staff during AVERT, a large international trial on acute stroke, and to describe trial management consequences. DESIGN Retrospective observational analysis. SETTING 56 acute stroke hospitals in eight countries. PARTICIPANTS 1074 trial physiotherapists, nurses, and other clinicians. OUTCOME MEASURES N...
