8 a.m., arrive at meeting site – The park gate on Burbank Boulevard, just west of Woodley Avenue. This is the kayak loading site and it’s roughly a quarter-mile upstream from Sepulveda Dam.
8:30 a.m., William Preston Bowling will greet everyone with liability waivers. Volunteers signed in, put on waders/sunscreen, and took the fishing gear and buckets down to the river at site 1 and Anglers bring their own gear and valid fishing license.
We are collecting fish to observe and throw back, showing all your catch to biologists once caught, they will decide what species to keep for toxicity study.
This will be the second outing of the third “Los Angeles River Fish Studies” created by FoLAR. This study is in Partnership with Stillwater Sciences and the Resource Conservation District of the Santa Monica Mountains.
Looks like we captured 3,699 fish, the majority of which were juvenile tilapia under 1 inch. Based on the few larger (up to 3 inches) fish, most appeared to be redbreasted tilapia (Tilapia rendalli), but that is not yet verified with the voucher specimens. These fish can breed year around in warm waters, and it was quite interesting to find such young fish at this time of year, but water temperatures were 24-27 degree C. (75-81 degrees F.), which is pretty warm. They can reach up to 18 inches and live for up to seven years.
They are native to Africa, and are primarily herbivores that spawn in the substrate and guard their nests. They are considered to be competitors with native fish for food and spawning areas, and high densities of fish can negatively impact native aquatic vegetation.
In other areas, they have not survived strong flows or colder temperatures, so it will be really interesting to see if they make it through the winter El Nino.
Here’s an updated message from organizer Rosi Dagit:
Alex and I will meet Bill by 7:45 and see if we can figure out how to open the gate – pending hearing back from MRCA. We will offload all the gear from my truck and stage it there either way.
8 am Meet Bill at the corner of Burbank and Woodley, see attached map where it says PARK HERE
We can direct you back across Burbank to the kayak parking area. Parking here at the Reserve involves a lovely 15-20 minute hike along Haskall Creek, back downstream under Burbank Blvd, through the south reserve and across the river, to grandmother’s house, oops, across the river and back upstream to eventually get to the kayak boat launch area where all the nets will be staged.
We recommend that you bring your lunch, water, etc. in a daypack so that you can carry it over 1 mile and have hands available to help with rods, buckets, waders, etc. (Full details here)
If you get stuck in traffic or have problems please call me at 310.488.6381 so we can sort things out.
Thanks everyone for your patience while we got this all sorted out! Looking forward to a fun day in the river on Friday. Can’t wait to see what we catch!
You can also email FoLAR’s William Preston Bowling at firstname.lastname@example.org for more information.
Update: because of permit issues, this event has been postponed until Friday, Nov. 20.
Attached please find the info for the upcoming fishing day.
We caught more fish in dip nets on our exploratory mission last Friday than we have at all other events. They were juvenile tilapia, but still!
We still need 2-3 more volunteers at least but the more the merrier! Please spread the word!
If some of the anglers want to bring kayaks and or floatie chairs along with their rods, there is a cool place under Burbank to send them.
We will also have lots of seine nets available.
Thanks to Bill for setting this up! thanks to all of you for your help in making it happen! This should be really fun!
If you are interested, please email me at email@example.com and I’ll send you the rest of the info.
