New Journal Article on Pacific Sardine Recruitment Predictors

Sam McClatchie and Kevin Hill of the Southwest Fisheries Science Center, with co-authors from Scripps Institute of Oceanography, have a paper in an advanced online issue of the Canadian Journal of Fisheries and Aquatic Sciences. The harvest guideline for Pacific sardine (Sardinops sagax) incorporates an environmental parameter based on averaged surface temperatures at the Scripps Institution of Oceanography pier (SIO pier) in La Jolla, California, USA, which would be invoked after a series of cool years to reduce commercial catches using a precautionary decision rule. The paper concludes that “…the environmental proxy derived from SIO pier temperature, which has never affected the harvest guideline since its implementation, no longer predicts recruitment of Pacific sardine, and should be removed from sardine management.” [Clipped from the abstract].
