I shared my sorry story with Diving Locker owner Jake Shelton, a diver for 24 years who has been based in San Diego for the last five years.
“I’ve never seen a cabazon in the canyon,” he said.
Jake sees them elsewhere in San Diego waters but even so, they measure no more than 12 to 18 inches long. Skeptical of my recollection from decades ago, he said, “Cabazon don’t get 3 feet long. You must be thinking of lingcod.”
After consulting two fish identification books (published in the 1980s), he said, “Wow, you’re right. Actually, it says they grow to 39 inches.”
Space limitations prevent me from sharing more anecdotes, but know that diminished marine life populations are pervasive across marine vertebrate and invertebrate species. And it’s not just numbers because overfishing has also resulted in below-average sizes (compared with historical data) of mature adult fish.
Reminiscing with diving pioneers who hark back 50 to 60 years highlights that despite my extensive local dive experiences, it’s not only Jake who has missed the extravaganza of underwater life that once existed. I have, too. One long-timer said it used to take 30 minutes for a school of silversides to pass by overhead off Point La Jolla. I’m jazzed if I count 30 seconds for an occasional school of sardines or mackerel to cruise by. I’m ecstatic to meet up with a rare 100-pound giant sea bass (Stereolepis gigas), but these are minnows compared with decades past when these fish were not only abundant but weighed in excess of 300 or 400 pounds.
It used to be that many places in the sea were too remote or too deep for people to access. These regions balanced out the negative impacts of human fishing and polluting activities occurring elsewhere. Our technology and consumption have all but eliminated most of these refuges, while our dependence on the ocean for clean air, clean water, food and recreation escalates along with our population. Designated Marine Protected Areas are a proven way to re-create the critical natural buffer zones of yore that acted to rebuild and invigorate stocks for the near and distant future. The no-take La Jolla Ecological Reserve, implemented almost 40 years ago, is only a baby step in this process because the reserve is not big enough. We need a larger buffer zone to promote critical recovery of vertebrate and invertebrate populations that have suffered from decades of overfishing and inadequate fisheries management. Reasonable policies have too often not been implemented because of pressure from powerful special interest groups. The result is historically low populations of many species, collapsed populations, and in regards to fish, populations dominated by small-sized adults.
Thankfully, it’s not to late to change course. By supporting the Marine Life Protection Act’s “conservation proposal,” we can extend no-take protection to the southern La Jolla reef system (encompassing south Windansea to Crystal Pier). The area includes a year-round kelp forest, rocky reefs, sandy flats and submarine canyon. While some species range across more than one of these habitats, many species are restricted to only one, making this tract of ocean the only reasonable choice to revitalize the widest number of species. Further, it is the only proposal that meets the guidelines promoted by the science advisory team that includes internationally respected researchers from Scripps Institution of Oceanography. Our support is particularly important because La Jolla boasts the most extensive and biodiverse rocky reef habitat n Southern California.
I’ve frequently wished I could take my dive gear, board a time machine, dial in 100 years ago and return to La Jolla. There I could thrill to dive in an unspoiled underwater world boiling with life. I’m realistic enough to know that can only happen in my dreams, but I’m idealistic enough to hope that the Blue Ribbon Task Force does right by Californians —those now living and those yet to be born. Heed the spirit as well as the rules laid out in the Marine Life Protection Act and accept the conservation proposal. Incorporating protection of the diverse marine habitats found off southern La Jolla will widely benefit all ocean life (and us!) elsewhere up and down the coast. The many species of marine life may now be small in size and diminished in population but they are there. We just need to get out of the way and let them flourish.
