Sardine Survey

2016 Sardine Cruise

Eggs are collected while ships are underway using the continuous underway fish egg sampler or CUFES.

We will update this page frequently during the survey.

All data are preliminary and may be revised after samples are verified in the laboratory. The data posted here should not be used to interpret status of the populations or the state of the environment. Further analyses and additional data are required to make such assessments.

Data are overlaid on an image of satellite-derived sea-surface temperature (degrees C) for the nearest two-week or one-month period based on AVHRR 1.4-km resolution measurements. White areas indicate no data or temperatures outside the range of 11-19 deg C.

2016 Winter CalCOFI CUFES sampling of northern anchovy eggs/minute plotted over Sea Surface Temperature (SST). Anchovy spawning temperatures normally are between 12-15 oC. The grey box represents the standard CalCOFI sampling grid.

Juvenile and Adult anchovy collected in the 2016 summer “California Current Ecosystem Survey” from June 20-September 6, 2015. Trawling occurred from north to south. Positive trawls for northern anchovy are indicated with white circles, black circles represent no anchovy in the trawl. Circle size does not represent abundance. Bars represent densities of eggs of sardine, anchovy, and jack mackerel collected with the Continuous Underway Fish Egg Sampler (CUFES).
