Endangered Fish Get a Lift to Safety After Wildfires

Of the many large wildfires that destroyed millions of acres around California during the 2020, one blaze in particular threatened to wipe out years of fishery conservation efforts. The Lake Fire in Los Angeles County burned more 31 thousand acres and it illustrated – for the second time in four years – what lengths dedicated biologists will go to in order to preserve California’s Unarmored Three Spine Stickleback (UTS). The UTS, Gasterosteus aculeatus williamsoni, is a state and federally listed endangered species and a State of California Fully Protected Species.

The Value of California’s Market Squid

Arriving on the heels of the farm to fork movement, the COVID-19 pandemic has disrupted supply chains and altered product demand, which has inspired businesses to restructure and Californians to pay particular attention to where their food comes from. Many understand that almonds, artichokes or lettuce are grown in their own backyard, mostly in the Central or Salinas Valleys. But when residents are asked about wild-caught food sources coming from the ocean, tuna, salmon or perhaps rockfish might immediately come to mind. While those are indeed popular fisheries, the largest of California’s commercial fisheries actually target invertebrates, not fish!

The Wildlife Disaster Network is Created to Meet a Burning Need

In early December 2017, wildlife veterinarians from the UC Davis School of Veterinary Medicine and CDFW teamed up to try to save the life of a black bear that sustained third-degree burns in Southern California’s Thomas Fire. The innovative treatment involved the use of tilapia skins as natural bandages for the bear’s paw pads while she recovered from her injuries at CDFW’s Wildlife Investigations Laboratory (WIL) in Rancho Cordova.
