grunion greeting, 2014 #4

female California grunion dug in sand laying eggs
while 4 males cluster around her head
 
It was all about the group fish p0rn this late 3rd night, high tide after the full moon.  We spotted numerous clusters of 4-5 males per female, as compared to one on one.  This only seems to happen when the runs are heavier, which makes sense.  The females are quite acrobatic, flipping themselves straight up into the air out of the sand to catch the next big wave back to the ocean.  It's totally fun to watch under the light of the full moon.

open season
4 spotted cusk-eels, 1 northern anchovy(?), several grunion

Steve the Fisherman was there (must recruit him!) with 6 other people and 2 buckets when we arrived.  They were the same folks from last year June 8 when Bob Lea measured fish.  They remembered me and asked if I wanted take measurements of their hand catch.  I did, which is a little tricky with wet fish and wet paper and wet pen and wet sand.  Have I mentioned it was wet?  And cold?  I have no idea what I was doing.  They told me they arrived around 10:30, started seeing cusk-eels around 11, and then the grunion followed with ~25 at a time.  I was impressed with how much they knew.  There was a tiny silver fish in their bucket (at 3 o'clock above) that did not look like a grunion.  I'm totally making a guess that it's an anchovy, because my other flash pics of it in my hand, in the dark, did not provide any detail.


Considering the bucket-toting folks were next to the wharf, Andy and I walked down the beach. About 250 yards down, there were another couple spots of grunion.  We stood between the two locations for most of our watch.  Andy walked down to the cement structure past a bonfire group, and he didn't find any additional grunion spots.  A couple hundred came up in a few waves around 12:30, but mostly it was maybe a dozen to 30 or so at a time over the course of 45 minutes that we observed them.  When we returned to the wharf, the group described hundreds coming up onto a long flat section of the beach.  It sounded like a W-3 to me.  For Monterey, this was a good grunion night.  To compare with my past observations, click to see a definite W-3 and a fantastic W-4.

grunion greeting

We try to arrive about 1/2 hour before high tide, because our experience has been if the grunion are going to run, they will usually have already started.  We also know that if we spot a black-crowned night heron (aka Charlie) on the beach as we pull up on the pier, there will be grunion.  This held true for both Wednesday (no blog post) and Thursday nights.  If there isn't too much human interference, we noticed the Charlies seem to know when the grunion are done and fly away. 

I submitted both night's reports to Dr. Martin through her online form and sent her an e-mail per her request because grunion sightings in Monterey are not common.  She invited me as her guest to the first Ocean Science Trust conference held at Asilomar last month.  The various perspectives on crunchable Citizen Science were extremely helpful to me as I embark on my own project.  Thank you, Dr. Martin!

I'm reformatting my typical grunion greeting blog posts, now 5 years after we began.  Man, I can't believe we've been doing this so long... okay, we did skip a year, because we got so discouraged from too many late nights with no grunion sightings.  I hope to add better information this year, although reading back through our experiences has been fun.

grunion greeting, 2013 #4

cusk-eel, grunion, and other fish


new moon cycle, 11:05-12:39, cloudy skies

This was a pleasant night and a nice way to finish off my birthday activities. When we arrived at the beach, 13 people were already there with buckets containing grunion, cusk-eels, and other fish. The local fisherman in the bunch said they arrived at 10pm and saw about 20 grunion thus far. This was their first time out since learning about grunion from the CA Fish and Wildlife schedule.  The other groups were a young family and a couple individuals.  Somewhat unusual compared to past grunion nights, everyone seemed incredibly respectful of the grunion (e.g., waiting until the female was done laying eggs before collecting her) and curious about what else was on the beach (e.g., Charlie and 3 of his night heron friends, a medium-sized sea turtle making its way parallel to shore, bioluminescence they had witnessed 3 nights before while sardine fishing).

I asked to take a quick picture of one of the small cusk-eels they had in their bucket before they let it go. It's too bad it's such a crappy photo. In any case, I discovered it's very difficult to find online information about the different kinds of eel-like animals. Fishbase.org has a searchable db, but like BugGuide in its early days, it needs more content to truly become a user-friendly site. Can anyone recommend an eel ID site?

At 12:07, we were all starting to pack up when another decent run of 60-80 grunion came up with a big wave. We stayed for the next half hour with another 2 runs at 12:20 and 12:37. I've reported this night as a W-1.  It certainly wasn't as exciting as May 26 (W-4), May 25 (W-3), or June 8 (W-2), 2013, but way better than no grunion (W-0) as has happened too many times in past years.

ps 05/18/14 - Thanks to a grunion greeting e-mail exchange with Dr. Guacamole and Dr. Martin and quotes from Bob Lea, the unidentified eel above has been identified as not a true eel, but a cusk-eel.  As to species, I can't say for sure.  Although, spotted cusk-eel (Chilara taylori) is mentioned quite a bit online for this area.  Paperbone (Lamprogrammus niger) and giant (Spectrunculus grandis) are reported for Monterey Bay as well.

grunion greeting, 2013 #3


new moon cycle, 10:23-11:40, cloudy skies

Welp, every grunion greeting night we've done has been a little bit different than the others. The only person we knew who showed up was Bob Lea, a retired marine biologist with the CA Fish and Game (er, Fish and Wildlife).  He has that calm, solid demeanor of someone who has spent a majority of his life outdoors.  There were several other people on the beach and the wharf with buckets and big lights, out to experience the spectacle that is a grunion run.  It's open season now, but I wish it wasn't since grunion in Monterey is such a rare sight.  One lady came for her grandchild, and she ended up having more fun chasing grunion than the boy who was quite scared of the fish.  I laughed at her pure joy and exuberance, even though I felt a little sorry for the mating grunion she snatched up.  Bob convinced a couple of the grunion captors to allow him to measure their caught fish.  In a dry bucket, the grunion quickly lose their blush or mint green glow and become quite silvery.  There was also a luau being held at the recently renamed Del Monte Beach House, complete with 80's dance music and karaoke, judging by the tone-deaf singing we heard.

Once again, the grunion did not disappoint.  Why couldn't we have seen this from 2009-2011? Numerous scouts were first spotted right after we arrived ~10:25.  Then shortly after high tide of 10:43, the grunion runs peaked with a couple hundred on the beach at a time.  The waves had an incredible reach up the sand, leaving many of us soaked.  I'm debating whether to report this as a W-2 or a W-3; the numbers were slightly less than the first night after the full moon 2 weeks ago.  The fish petered out by 11:05, right before last call for alcohol and horrendous singing ensued from the luau. After most of the people left, Charlie and 3 of his night heron buddies joined the after-party.  A gull gobbled up a lone grunion at 11:27.  We ducked out very pleased with our excursion at 11:40.

grunion greeting, 2013 #2

full moon cycle, 11:33-12:46, cloudy skies

Greet, greet, greet.  Why, hello.  Welcome.  The grunion (Leuresthes tenuis) did not disappoint for a second night in a row.  I'm debating as to which Walker Scale rating to call this run.  I'm leaning towards reporting it as a W-4.  The character of this run was very different than the night before.  It's difficult to say if there were more fish overall, but they were definitely more heavily concentrated in a much smaller area of beach and for a shorter amount of time.  Andy walked it out and figured they stretched across about 15 yards wide at the most numerous, whereas the previous night they stretched at least 2-3 times that length.  This run didn't last long.  In fact, it was pretty much done by high tide of 11:50.  It's a good thing we arrived early.  What struck us was that these fish were significantly smaller in size than last night.  Younger, maybe?  The waves were extremely gentle, and we noted how loud the fish slapping sound was.  Amazing. Charlie didn't show up until we were getting ready to leave.

The human activity on the pier was also very different from Saturday night, even though this was a holiday night.  It was pretty much deserted, except for one lady I recognized from our annual Easter festivities and from around town.  I was sad to discover she's obviously homeless.  She seemed embarrassed and tried to hide in the porta potty (she kept peeking out to see if we were still standing there), so I didn't start a conversation with her.  If I see her again during the daylight, I'll see what I can do for her.  Sometimes I wonder if we're considered weirdos for going out in the middle of the night to watch fish.  Seriously.  We tried to rally friends to come out and meet us since this is such a rare local occurrence, the last time being the summer of 2007, six years ago! Even with lots of returned enthusiasm, only two former classmates of Andy's showed up. They're both teachers, one in elementary and the other in high school science. We walked the beach towards the cement structure and found another small patch of scouts and maybe 5-20 grunion per big wave.  We laughed at how in past years, we would have been over the moon to see 20 grunion.  It was a good night for us.  Sigh.

grunion greeting, 2013 #1


full moon cycle, 10:42-12:15, mostly clear skies

Happy dance, happy dance!  Finally!  Here's my long-awaited W-3!!! Woohooo!!!!!  I even called the grunion greeter 1-800 hotline and everything, because you know, I saved the number in my phone all these years.  Awesome.

Grunion runs are better known in SoCal south of Point Conception, although they have been reported as far north as San Francisco Bay.  Back in 2009, Andy and I signed up for this citizen science project, the first ever in Monterey to monitor the unusual grunion spawning runs.  We went out a total of 15 times in 2009, 6 times in 2010, 3 times in 2011, and zero times in 2012. Our biggest previous find was back on June 7, 2009 with a whopping 31 fish.  Over the course of 18 subsequent observation nights through 3 years, we only saw 15, 8, and 2 additional fish. It became too discouraging after a while to stay up so late for the full or new moon cycle high tide, dress extra warmly for the chilly, windy Monterey area beaches (we're definitely not like SoCal where they run around in shorts in the summer - ha!), trudge ourselves to the beach, wait around for an hour and a half or so in the dark, ooh and ahh over dead birds and camped homeless on the beach, stagger our freezing cold, wet, and sandy feet back to... eh-hem, well you get my drift. All for what, to count a handful of fish, maybe?  The worst was trying to function the next day on only a couple hours of sleep after 3 nights in a row.  Dr. Karen Martin at Pepperdine University and I have kept in contact through the years, and she and I have traded both encouragement and discouragement about the situation here in Monterey.  I held out hope.

When we pulled into parking at 10:42 well before the 11:02 high tide time, our good ol' friend Charlie was there with 2 of his night heron buddies and an oddball gull gobbling up fish.  From then until exactly 11:45 huge groups of grunion, maybe 30 to 300 at a time, washed up with each wave, dug themselves into the sand, danced a little dance, and then slithered and flopped back to the water with the next big enough wave.  We saw well over 1000 grunion, if not more. Makes that previous record of 31 from 4 years ago seem kind of paltry.

Okay, so, I fully admit I was molesting the fish by flashing my camera left and right to catch the action.  I still had the nerve to tell people with buckets that grunion season is closed.  Andy wasn't so sure, but I remembered April and May are no collecting months.  One fellow became verbally challenging, which gave Andy a major bad vibe about the guy.  Fortunately, his cohorts were cooperative.  Another fellow was picking up grunion right in front of us and putting them into a plastic shopping bag.  Initially he pretended he couldn't speak English, but I was adamant that he return the fish to the water.  Reluctantly, he did with the intention to return later.  I felt kinda bad for my bullying behavior.  Then, a fellow up on the pier related a story to me of how one time in SoCal a friend of his shouted "La luna, la luna!" and disappeared for a few minutes only to return with bags full of grunion.  They cooked them in tin cans over a fire.  He said they're a sweet tasting fish and the "caviar" was good.  I had the suspicion that he was homeless with a dirty duffel nearby. I liked him because he was very polite and kept calling me "Holy Lady".  We eventually left when we hadn't seen anymore grunion for half an hour.  Plus, the illicit pier activities seemed to uptick after midnight, complete with a man vomiting out of a parked car next to mine.  That was totally gross, and the other stuff made us nervous for our safety.  We're not sure if we're going to out again Sunday night since high tide will be later and the weather is looking chillier.

grunion greeting, 2009 #7


full moon cycle (11:05pm - 12:35am), partly cloudy skies

We arrived at Del Monte Beach at 10:35pm. The private cruise ship The World was there again to light up the waters. There were 4 adults and 1 boy out in the water catching grunion. Another group of young people and their dog, which happily ate a grunion, stopped by to check out what was going on. Diane and her coworker Steve also arrived ~11:30pm and walked down the beach together. I felt badly Steve didn't get to see a live grunion except for in a bucket. Before we left at 12:15am, our friend Charlie the night heron came to visit, but there was still too much going on for him to hang around much.

We saw 15 grunion total, with 11 of those showing up before the 11:05 high tide mark. Most were within 25 yards of the pier and at about the 7th parking meter from the bathroom (it didn't seem as high of a tide as during the new moon). We also counted 6 small crabs ~2" wide. This was the first time we've noticed crabs. They floated in on a wave and then quickly buried themselves in the sand. I tried to pick one up, but its pinch was pretty strong for such a little crab.

I talked with one fellow who was collecting and he seemed to know quite a bit about the grunion, including the behavior of scouts. He witnessed a huge grunion run with silvery flashes as far as the eye could see down the beach in June or July of 2007 on a full moon. His girlfriend confirmed the year. There was a beach party at the Adventures by the Sea rental and birds were lined up all along the shore. He said the air smelled like cucumber and noted that happens whenever there's a big run (I found this observation particularly interesting). He said as more people came out to check the run, it seemed to him that there were fewer grunion. He walked down the beach to the cement structure where it was darker and quieter and found even more grunion than by the pier. My husband was excited to hear this part of the story, because he suspected the cement structure would be a prime grunion "hot spot."

The 4 adults arrived a little after 10:00pm and collected 22 grunion. I know they saw quite a few more, because they were having a hard time holding onto the wiggly grunion. They planned to fry the fish whole. The boy managed to catch 3 grunion until his family came to drag him home.

I can't help but wonder if all the grunion collecting and activities stalled a big run from occurring these 2 nights.

ps 10/07/10 - I originally posted the above as an unknown crab. Thanks to a better picture from another grunion greeting night, I was able to ID this crab.

grunion greeting, 2009 #5

For a couple who religiously gets to bed by 10pm, all this late-night grunion greeting has whacked out our sleeping schedules! Technically, Tuesday night was not a Monterey monitoring night, but we were awake and fantasizing about calling the grunion hotline to report a W-3. Two nights before, we were thrilled just to see a handful of live grunion... hahaha, isn't that human nature, always wanting bigger and better? So we headed down to Del Monte Beach from 11:40pm-12:40am. Why not?

The skies had cleared up and it was extremely dark without a moon. We managed to see not one, but 2 black-crowned night herons in good ol' Charlie's favorite hunting spot. Between 12:22-12:25am, one of the night heron caught 2 grunions. That's it. We didn't see anything else.

Phooey! Our aspirations to report a W-3 will have to wait.

grunion greeting, 2009 #4


cormorant & grunion
new moon cycle (11:25pm - 1:05am), overcast skies

It's a little disturbing at how many dead or injured birds we've seen this year, including during our grunion watching. I'm guessing the dead black bird is a cormorant. There have been reports about dead birds on the beaches.

We went out earlier than requested at 11:05pm, because the night heron (we've started calling "him" Charlie) was already hunting on the berm the previous 2 grunion nights when we arrived. As expected, he was at his favorite hunting spot, about 20 yards from the pier and between the 6th and 7th parking meters from the bathroom. We saw our first grunions immediately from the pier before we could even get down to the beach. Unfortunately, Charlie flew off shortly after we got down to the beach; we wonder if he was already full or simply didn't want to deal with us chasing after him every time he caught a fish. There was also a pelican diving into the water throughout our time on the beach.

We counted 19 total grunion in 2s or 3s: 12 by us from 11:05-11:35pm; 4 by Diane a fellow grunion greeter and her MBA friend from 11:45pm-12:15am; and 3 by all of us at 12:20am.

Since this was the first time after the workshop night that fellow grunion greeters were at Del Monte Beach, we left Diane and her friend shortly after they arrived and headed down the beach together to the cement structure with hopes to find other grunion "hot spots." No such luck, but it was very peaceful and meditative. The city lights reflecting off the clouds made it easier to see compared to clear skies and a full moon. The no-flash pic above is brighter and more orange than it actually was.

Just like the previous time, it was challenging to take a picture of the skedaddling grunion. They're awfully quick!
