14 Why do we care about conditions adults experienced in 2014? Parental experience matters: parental temp/discharge exposure-gamete viability maternal stress -egg size & fry size maternal stress & disease status -fry swimming ability fertilization temperature -egg survival Challenge is linking individual-level research results to population-level consequences D. Patterson & K. Robinson, E-Watch 14

23 Changes in water temperature are reflected in changes in zooplankton species composition northern-type zooplankton occurred along Vancouver Island in 1 st half of 2014 when water was cool (large nutritious species, good for fish) 1 mm but, southern-type zooplankton in 2 nd half of 2014 and in 2015 when water was warm (small poor quality species) Author: Moira Galbraith and Ian Perry (DFO)

24 Ricker broke down in 2016 so survey late-- so CPUE difficult to interpret this year No indication of any poor condition of juveniles 24

40 Definition of COSEWIC terms and status categories: Extinct (X): A wildlife species that no longer exists. Extirpated (XT): A wildlife species that no longer exists in the wild in Canada, but exists elsewhere. Endangered (E): A wildlife species facing imminent extirpation or extinction. Threatened (T): A wildlife species that is likely to become Endangered if nothing is done to reverse the factors leading to its extirpation or extinction. Special Concern (SC): A wildlife species that may become Threatened or Endangered because of a combination of biological characteristics and identified threats. 40
