Summary of Dosidicus gigas size, sex, and maturity. Dataset Description: <p>Summary of <em>Dosidicus gigas</em> size, sex, and maturity from BIPXII cruise in October 2013 in the Central Gulf of California, Mexico, Santa Rosalia (27.3N, 112.1W) to Bahia Las Animas (28.9N, 113.3W) to Guaymas (27.8N, 111.3W).</p> Methods and Sampling: <p>Squid were captured during rod-and-reel jigging sessions using weighted, luminescent jigs (8–50 cm length) fished at depths from 200 m to the surface. Measurements were made on the research vessel within 1-2 hours of capture. Length was measured with a flexible tape, generally to the nearest 0.5 cm. Mass was weighed with a digital hanging scale to the nearest 0.1 kg. Sex and maturity were visually determined following criteria for Stages 1-5 (Lipinski &amp; Underhill, 1995): Stage I–II = immature, Stage III = maturing, Stage IV–V = mature. (See also Hoving et al. 2013.) CTD data from these sampling sites are also available and have been deposited with BCO-DMO.</p>

Adaptable life history strategy of a migratory large predator in response to El Nino and climate change

Adaptable life history strategy of a migratory large predator in response to El Nino and climate change
<p><em>Description from NSF award abstract:</em><br />
This project will examine the response of <em>Dosidicus gigas</em> (Humboldt squid) to an El Niño event in 2009-2010 that was accompanied by a collapse of the commercial fishery for this squid in the Guaymas Basin within the Gulf of California. This large squid is a major predator of great ecological and economic importance in the Gulf of California, the California Current, and Peru Current systems. In early 2010, these squid abandoned their normal coastal-shelf habitats in the Guaymas Basin and instead were found in the Salsipuedes Basin to the north, an area buffered from the effects of El Niño by the upwelling of colder water. The commercial fishery also relocated to this region and large squid were not found in the Guaymas Basin from 2010-2012, instead animals that matured at an unusually small size and young age were abundant. A return to the large size-at-maturity condition has still not occurred, despite the apparent return of normal oceanographic conditions.</p>
<p>The El Niño of 2009-2010 presented an unforeseen opportunity to reveal an important feature of adaptability of <em>Dosidicus gigas</em> to an acute climatic anomaly, namely a large decrease in size and age at maturity. Now these investigators will have the opportunity to document recovery to the normal large size-at-maturity condition. The specific aims of this project are:</p>
<p>1) continue a program of acoustic surveys and direct sampling of squid that has already been established in the Gulf of California in order to assess distribution, biomass, life history strategy diet, and migratory and foraging behaviors relative to pre-El Niño conditions and<br />
2) conduct analogous surveys in Monterey Bay, California in conjunction with long-term remote operated vehicle surveys of squid abundance.</p>
<p>The data from these studies will provide a comparison of recovery in the two different squid populations and yield valuable insights into what ecological effects an area is expected to experience with an invasion of either small or large Humboldt squid. As long-term climate change progresses, squid of both forms may expand northward into the California Current System.</p>
