Diver Day at the Aquarium of the Pacific – March 11th

aquarium-of-the-pacificIt’s been such a wet winter in California that we haven’t had much time to get in the water  with our finned friends. The Aquarium of the Pacific wants to help you with your marine withdrawals and is offering free admission to certified divers showing their c-cards and accompanying I.D. There will also be exhibitions by a lot of great local marine scientists and NGO’s talking about the state of California’s ocean and how you can help. It’s a great time to get out with  the ocean community and enjoy a dry day with the fishes.

Ocean Science and Abalone and why trying to bring them back isn’t shellfish

red-ab_p-haaker

Red abalone by Peter Haaker, fisheries biologist California Department of Fish and Game

It’s hard to imagine that at one time abalone were as thick as 70’s shag carpet on the rocky reefs of California. Native American coastal tribes, not having actual 70’s shag carpet, gathered them as a staple of their diet and culture. Excavated shell mounds marked the sites of tribal villages along the coastline. Later, Asian immigrants established major fish camps as they started to dive the local shallows in pursuit of this shelled delicacy which later developed into a major commercial fishery after World War 2. In fact, at the peak of the commercial fishery in the 1960’s, California commercial fishermen were landing 4.6 million pounds annually. This was a true ocean love story. Boy meets ab. Boy harvests and sells ab. People saute and then eat ab. It was an ocean fishery success that no one thought could ever end until it did. Serial depletion and natural phenomenon made an unholy alliance that combined to crash the fishery starting in the 1980’s , shutting it down commercially statewide and recreationally south of Pt. Yankee by the mid 90’s.As an end result, over 25 years worth of divers were certified in Southern California not knowing what an abalone was because they’ve never seen one.

As far as biological extinctions go, this one produced mixed results. Die hards could still take them recreationally along the isolated and intimidating north coast. Southern and Central California kind of moved on with both commercial and recreational endeavors becoming more focused on the spiny lobster and red urchin. It was almost as if everyone just kind of threw up their hands and said “okay, what’s next?”

Almost everyone.

It started as kind of a hail Mary. What if we could restore the fishery? What do we need to know to make this happen? How do we then physically do it?  Reseeding hundreds of miles of nearshore habitat with a enough abalone to produce a viable broadcast spawning population seemed, on the surface, pretty far fetched (***Broadcast spawning means all the abs throw their stuff in the air(or water) like they just don’t care and hope there is opposite sex genetic material getting expelled close enough to connect.)

This is when necessity called in those that can try to make it happen. This is when necessity called in the scientists.

Right now in California, there is an amazing array of scientists working on restoration of the abalone population. Work is being done by federal agencies, state institutions, and non profits to study and ultimately restore this missing part of today’s kelp forest landscape. Listed below are just a few of the projects going on that you should know about that are working to make our nearshore waters a healthier, and more importantly, and  a more balanced place. So read a paragraph, learn a little, and think a lot about the types of programs and science you should be supporting. The ocean you save could be your own. See you out there.

With the collapse of multiple species of abs, there has been the obvious question of what’s first? In California, the white abalone is the first invertebrate to be placed on the Federal Endangered Species list. NOAA scientist are currently studying the collapse of this deeper water ab and collecting brood stock to replenish the population.

In a joint effort between NOAA and The Santa Monica Bay Foundation, as well as support from The Nature Conservancy, scientist are working to develop methodology and facilities needed to restore abalone in the southern California bight.

A very cool and ambitious program that not only is striving to restore native green abalone populations in southern California, but also to create the education component that will help Californians understand why they should care about abalone and why they are important to our oceans health. Here is a great read from the Orange County Register about the great work Nancy Caruso at Orange County’s Get Inspired  is doing.

Yes, We’ve still got Ocean Problems in California – Throw Back Thursday

cfdaltlogoIn a world that seems to be more filled with uncertainty than ever these days, we at California Fine Diving would like to give a little perspective on where we in California are in terms of ocean health. This photo, provided by the Mendocino Historical Society, shows a couple of dapper turn-of-the-20th-century fishermen with what I think we can all agree is a pretty good days effort. From a cursory look, we can probably also agree what they lack in modern fishing technology, they more than make up for with ties and bowler hats. Looking good and fishing good.

Now I’m not posting this just because it’s a great shot( it is wicked cool though). I’m posting it because It gives us a sense of something we’ve lost in terms of abundance and variety that we’ll probably never get back. Look closely at the picture. There are more giant sea bass(GSB) in this picture from one day of fishing than most divers saw during the entire decade of the 90’s. I’m also not saying all is lost BTW. We are seeing a lot of species making a comeback. Divers regularly see GSB these days even if the populations are probably not back to historic levels that existed when this photo was taken. I’m pointing out by posting this picture, however, that we’ve barely started working our way back to a place where we can say our local waters are as healthy as we want them to be. We have to keep working on it. The only way to do this is to stay involved and active. We can’t count on anyone or any entity other than ourselves. We’re all in this together and the ocean you save will be your own.

Good luck and we’ll see you out there.

Return of the King

Stereolepis gigas doesn’t sound much like a king’s name. It sounds more like someone you’re going to buy a gyro from. Don’t be deceived however because this is is the scientific handle of one of the most magnificent creatures you’re likely to encounter diving here in California — the Giant Sea Bass(GSB).

kingAptly named because it is actually quite giant, this highly protected species seems to be making a bit of a comeback from it’s darkest day in the early 80’s when California DFG(now the DFW) officials were scrambling to protect this vulnerable and venerable giant from rod and spear. Following a ban on gill netting in nearshore waters in 1994, sightings increased and  casual observations over the past 10 to 15 years seem to indicate that this king of the kelp forest is making a comeback. To get real answers, GSB turned to real scientists and the process of collecting relevant data has been carried out in earnest. As a result, we now know a lot more about the life cycle of the GSB than we ever did before and are therefore better equipped to conserve this magnificent creature. One of the lead scientist in the study of Giant Sea bass, Dr. Larry Allen, Biology department Chair at Cal State Northridge and leading GSB expert, is giving a presentation at the Cabrillo Marine Aquarium on February 3 to discuss what we now know about the GSB and  their chances for recovery. Presented by Alta Sea, this a great chance to learn more about our impact on the animals of the kelp forest and how we can make a difference through community based programs such as the Giant Sea Bass Collective organized through a joint program between CSUN and UCSB. It looks to be a great evening and best of all it’s free. So don’t be a uniformed bump on the log. Get out of the rain and down to San Pedro. We look forward to seeing you out there.

The Return of the Kelp Forest King

By Dr. Larry G. Allen, California State University, Northridge

Larry is currently Chair and Professor of Biology at California State University Northridge. He has co-authored and edited many publications on the biogeography and ecology of marine fishes of the Pacific coast of North America including the books, “The Ecology of Marine Fishes: California and Adjacent Waters” and “A Field Guide to the Coastal Fishes from Alaska to California.” Dr. Allen will discuss the information that he and his graduate students have compiled on the demise and recent return of the apex predator of California’s southern kelp forests, the Giant Sea Bass, Stereolepis gigas.

It’s Election Day! Please Vote for the Love of the Ocean

herring

Photo and awful, awful pun courtesy of someone who shall remain nameless because i told her I thought it was funny earlier today and now I deeply regret that decision.

Today is a big day in America whether you’re a red diver or a blue one. As people who care about the ocean, we have a chance and responsibility to speak  for an ocean that needs our help because it cannot speak for itself. So when you’re out there voting, think about who is going to protect the ocean and who is going to exploit it. Think about who is going to support science-based management and who is going to say “I’m no scientist but…” And finally, think about who is going to champion the ocean for the love of our world on behalf of all humanity. #allvotesmatter

Los Angeles Waterkeeper Divers Battle The Devil……weed off of Palos Verdes!

A few months ago, CFD spent some time talking about the importance of divers working as stewards of their own local waters  by profiling the Los Angeles Waterkeeper and their Dive Program Manager Ian Jacobson. LAWK divers had just finished their part in a  NOAA-funded kelp restoration project in the Los Angeles South Bay and were looking for support and participation for their next project, the removal of sargassum horneri, an invasive algae taking advantage of El Nino warming to run wild all over the Southern California Bight. We’ll, Ian and his divers are in full swing, and with the help of NOAA scientists,  are using new technology to remove the devil weed from great swaths of our nearshore rocky reefs. The Los Angeles Daily Breeze recently profiled the efforts of these divers and it’s well worth the read. It’s also a great example of what an impact local citizens can do to directly benefit our nearshore environment. For a chance to help, check out the dive program page at Los Angeles Waterkeeper and find out what you can do .  Another link to the article appears below. Just click on the pretty scary picture.
