North 9 to La Jolla and bluefin/ thresher request

[dos ballenas]

Launched out of Mission Bay. Grabbed a great half scoop of sardines that lasted all day. Smooth seas and no wind for the first time I've been out all season! Had to make the call and go as the weather looks to turn for the worse later this week!

Started at the north 9. Worked up and down the bank from the inside to the outside. Water looked great with some of the paddies holding a lot of bait. Temps from 64.4 in the morning and then up to 67.3 by the time the sun got on it.

Tons of mola mola feeding on velella on top of the bank in the warmer water. Pretty cool to watch them slurp those things down.

Mowed the lawn on the 9 for 4 hours without any sign of tuna or yellowtail. They could have been there but were't showing on the surface. Great day on the water and given the conditions I wouldn't be surprised if those fish down south push up and onto the 9 any day now!

Headed back into La Jolla around 11. The water looked great all the way in with bird life, an elephant seal, and scattered kelps. Water in LJ has cleared up a bit since last weeks wind event. Spooked a yellow in 30 fathoms straight off the road hole. That was it for La Jolla.

Anyways, I have a feeling that the bluefin will be within kayak range again this year! One of you guys needs to land a fish over 100 lbs already! This is what they looked like last year



Also. if you guys do get into them please take a minute and think about donating your carcasses towards furthering our understanding of these magnificent fish.

The Highly Migratory Species research team at NOAA’s

Southwest Fisheries Science Center needs your help

collecting gonads (reproductive parts), stomachs, and

otoliths from locally-caught tuna. In recent years, large

(150-275 lb.) Pacific bluefin tuna (Thunnus orientalis)

frequented California. If history repeats itself in 2017,

we are asking for your help to collect samples from these

large fish.

It is generally accepted that Pacific bluefin tuna only

spawn in two regions in the western Pacific (right ). After

hatching, a portion of the young bluefin migrate to the

eastern Pacific Ocean to forage and grow. These

bluefin usually return to the western Pacific Ocean as

they approach sexual maturity at around 3-6 years old

(4-6 feet in length). However, in recent years fish that are

potentially old enough to be mature have remained in

the eastern Pacific for longer than usual, prompting new

research and questions. One of our main objectives is to

examine gonads from these fish to see if they are mature

and determine if they are spawning offshore of California.

While gonads collected so far have not exhibited

developed ovaries or any evidence of spawning, we need

more samples to be conclusive.

If you would like to share your bluefin tuna carcasses,

please keep samples on ice to preserve freshness and contact

us as soon as possible to arrange for timely pickup.

Any and all samples you provide will improve the quality

of our science!

Ovaries collected from a 168-pound immature female bluefin
caught in 2015. Thank you for donating this fish Ryan Lawler!
Looking at the stained ovaries under magnification we see the
undeveloped eggs in purple.





I work on bluefin research daily and need you help! Spread the word! If you don't fish for bluefin but have ftriends that do let them know!

We also do thresher shark biology work. Please see the flyer below

Southern California is a known pupping and nursery ground for the common thresher shark
(Alopias vulpinus) and large pregnant threshers are sometimes caught by recreational anglers.
The Southwest Fisheries Science Center conducts research on the reproductive biology of common
thresher sharks and is looking for samples from females 140 cm fork length (4.6 ft) or
larger, preferably pregnant. If you happen to keep a female common thresher, please provide a
section of backbone, the reproductive system as shown in the figures below, and if possible, the
whole head. If you are not sure what to remove, just include everything from the belly. Please keep
thresher samples on ice or as cold as possible.

thanks,

Owyn

I sure hope to be lucky enough to help you out!

Are you any relation to Bob Snodgrass - I reported to him when he was head curator at the old Scripps Aquarium, back when it was down by the pier. That was quite a few years ago in a past life...

You may be able to set up some type of deal with the fish processing spots out in San Diego. I know they fillet a lot of big Bluefin when they get caught.

How far out till you hit the chloro break? I'll be trying soon, thanks for the encouragement Owyn.

I will share your request with my motor-powered friends and see if i can troll up any big BF guts for you. Thank you for all your hard work!

Yes sir. I am his son. Small world! I loved the old aquarium... spent many days messing around with their fish!

Yeah, I work with the processors already. But thanks for the suggestion!

Just trying to reach out to people that might not be aware....

Thanks Chris.

Not sure how far. Wasn't really paying attention as I had two target destinations and nothing in between... aka fish the 9 then run LJ then home.

Hope I have the opportunity to donate Owyn, see you out there! All the best!

How awesome! Followed in Dad's footsteps...
I should have, going to work would have been much more interesting.
My dad had a multi-million dollar view corner office up at the old Southwest Fisheries building - the one that was falling off the cliff and was torn down. I spent my whole childhood in the basement there looking in fish tanks. He went on to start a lab in Panama for the IATTC studying larval tuna, I got to spend a summer visiting him there. What a blast fishing for Humbolt squid while he night lighted larval tuna for study...
