The first image displays probability density functions for rmax, representing the maximum intrinsic rate of increase for various breeding stocks, including BSA, BSB1, BSB2, BSC1, BSC3, BSD, BSE1, Oceania, and BSG. Each plot shows the median rmax and its confidence interval, offering insights into the reproductive potential of these populations. The second image illustrates the projected recovery of these breeding stocks from 1900 to 2015, depicted as the ratio of projected abundance to carrying capacity. This temporal recovery curve, along with associated confidence intervals, highlights significant historical declines and subsequent recovery trends for each stock. Key metrics such as Median K, Median Nmin, Baseline year of abundance estimate, Projected abundance 2015, Recovery (N2015/K), Assessment model type, and Reference are detailed in a table for BSA, BSB1, BSB2, BSC1, BSC3, BSD, BSE1, BSO, and BSG. The data indicates varying levels of recovery across different stocks, with some showing strong recovery to near or above carrying capacity by 2015 (e.g., BSC1, BSC3, BSD, BSE1, BSG), while others (e.g., BSA, BSB2, BSO) exhibit more moderate or incomplete recovery. The assessment models employed range from single-stock models to more complex multi-stock models, with specific references to International Whaling Commission (IWC) reports. This analysis is crucial for understanding the effectiveness of conservation efforts and informs future management strategies for these whale populations.",{"@graph":14,"@context":73},[15,34,56],{"@type":16,"itemListElement":17},"BreadcrumbList",[18,23,27,31],{"item":19,"name":20,"@type":21,"position":22},"https://docshare.wps.com","Home","ListItem",1,{"item":24,"name":25,"@type":21,"position":26},"https://docshare.wps.com/document/","Document",2,{"item":28,"name":29,"@type":21,"position":30},"https://docshare.wps.com/document/research-report/","Research & Report",3,{"item":32,"name":10,"@type":21,"position":33},"https://docshare.wps.com/document/breeding-stocks-population-recovery-analysis/182303/",4,{"url":32,"name":10,"@type":35,"image":36,"author":41,"headline":10,"publisher":44,"fileFormat":47,"inLanguage":8,"description":12,"dateModified":48,"datePublished":49,"encodingFormat":47,"isAccessibleForFree":50,"interactionStatistic":51},"DigitalDocument",{"url":37,"@type":38,"width":39,"height":40},"https://docshare.wps.com/thumbnails/breeding-stocks-population-recovery-analysis/182303.png","ImageObject",300,407,{"name":42,"@type":43},"Oliver Hayes","Person",{"url":19,"name":45,"@type":46},"DocShare","Organization","application/pdf","2026-10-17","2026-09-02",true,{"@type":52,"interactionType":53,"userInteractionCount":55},"InteractionCounter",{"@type":54},"ViewAction",13,{"@type":57,"mainEntity":58},"FAQPage",[59,65,69],{"name":60,"@type":61,"acceptedAnswer":62},"What is rmax and why is it important in this analysis?","Question",{"text":63,"@type":64},"rmax represents the maximum intrinsic rate of increase of a population, indicating its reproductive potential.
