San Diego Coastkeeper's lab manager conducts an experiment on water quality using San Diego River water and common household fertilizers. The results of his experiment show how much murkier water becomes after a small amount of fertilizer is added. Imagine all of the fertilizer used in San Diego County and how, when it makes its way into our water, it collectively adds up. Learn more at http://www.sdcoastkeeper.org.

Recently, LUSH volunteers teamed up with San Diego Coastkeeper to help clean a local beach. In just 2 hours, they collected over 2500 pieces of plastic, more than 800 cigarette butts, and over 600 pieces of Styrofoam—totaling almost 27 lbs of trash!

Twice-a-month, Coastkeeper, and our partners Surfrider Foundation, San Diego Chapter, hosts a local beach cleanup like this one. If you love your beach and like it clean, bring your friends and family to volunteer at our next event! All of our upcoming beach cleanups can easily be found by visiting this link: http://www.sdcoastkeeper.org

Fishable Facts

  • Kelp forests play home to more than 700 species of marine creatures.
  • Many factors including pollution, climate change, and over-fishing contribute to kelp forest decline, and their collective impact is far greater than any individual stressor.
  • Research has shown that grazing by inflated sea urchins populations damaged kelp forests and slowed recovery in the '50s to '70s off Point Loma. Sea otters, lobster, and sheephead fish are important predators, keeping urchin populations in check.
  • Many fish off California's coast are in such decline that some species will take 50-80 years to recover to healthy levels.
  • La Jolla's lush kelp forest is like a stand of underwater redwoods – it provides food and shelter for hundreds of species, from tiny invertebrates to fish, mammals and birds.
  • Since 1990, revenues from commercial fishing have declined by more than half and the number of fishing boats calling at California ports has declined by nearly three-quarters.
  • Average size across a wide range of West Coast fish is down by half from 20 years ago.
  • A 40-cm bocaccio rockfish produces an average of just over 200,000 eggs per year, whereas an 80-cm fish at double the length produces nearly 10 times as many eggs (2 million)!
  • Nearly 80 percent of marine debris comes from land-based sources.
  • Regardless of their size, plastic pollution bits are not digestible by any creature.
  • More than 60 percent of all marine debris is plastic.
