Sardine Research Update – Southern California Report

We extend huge thanks to Nick Jurlin on the FV Eileen, Robert Terzoli on the Maria T, and Neil Guglielmo on the Trionfo, as well as our pilots Jeff Luboff and Devin Reed for their dedication to this research.

Through August 28, they have completed 12 preliminarily acceptable sets, targeting the smaller schools (as instructed to do). For the next two weeks they’ll be targeting schools at the larger end of the spectrum — up to 80 tons.

Below is a photo of Nick Jurlin approaching a small school near the Northern Channel Islands; his target is highlighted with arrows. The pilot estimated the school at 5 tons; Nick estimated close to 6 tons, and the point set verified the weight at 5.3 tons. This photo was enhanced by Dr. Doyle Hanan, the scientific advisor and field coordinator for the research project, and shows numerous sardine schools.

Nick, Robert Terzoli and Vince Lauro will continue making point sets in Southern California until we fill the projected SoCal research allocation (about 1,050 metric tons). They have about 800 mt to go, but targeting the larger schools (i.e. 50-80 tons each), that tonnage should be caught relatively quickly.

All fish landed in Southern California will be processed either at Tri-Marine or State Fish Company.

Thanks to everyone involved in our California research project for your dedication and cooperation!

Sardine Research Update – Northern California Report

Weather continued to play a confounding role in Northern California, but we managed to find enough reasonably clear days to complete one full set of 66 aerial transects coast-wide, from Cape Flattery WA south past Catalina Island in S.CA,. and nearly finished set #2 by the last weekend in August.

Three planes participated, with pilots flying at 4,000 feet altitude along predetermined straight line transects from shore out 35 miles. Transects were spaced at 15 mile intervals along the coast. Cameras mounted in the planes continuously photographed a swath of ocean approximately one mile wide along each transect path. Photo analysts will later examine the thousands of photos to identify sardine schools.

Three (replicates) is the charm that will help lower the coefficient of variation fraction applied to the estimate of biomass derived from photo analysis. Remember, last year’s survey completed only 41 of the scheduled 52 transects — with only one replicate.

This year, our target is 66 transects times 3 replicates. We’re nearly two-thirds of the way done with two weeks remaining. Finishing the third replicate should be doable.

The next challenge is landing acceptable point sets, and we’re making steady headway on that front as well.

In Monterey, while planes have been able to conduct aerial transects in the north, the combo of fish location (all piled up on the beach) and persistent marine layer offshore have precluded starting point sets in Monterey — until now.

Anthony and Andy Russo, Frank Aliotti, and now Neil Guglielmo, one of our southern research boats, who ventured up to Monterey, are standing at the ready to help initiate point sets in the northern region. One of our northern pilots, Geno Zandona, spotted fish at Soquel Hole, which means sardines may now be returning to the bay, as the abundance typically increases in September.

We’re hopeful the fish schools will spread out so we can conduct point sets in a broad area, as recommended by scientists.

Doyle Hanan advised the boats to prepare to go fishing on Tuesday, Aug. 31. Geno prepared to set the boats while the second pilot, and Allen Hewitt flies the twin engine Seminole to Crescent City to begin the third set of transects.

Although fog did not lift sufficiently in the Bay to fish on Aug. 31, we’re expecting a fair weather break for the next several days, and we should be able to make “hay” while the sun shines. Keep your fingers crossed!

This research project is likely to go down to the wire. We have until September 14 to wrap up the summer project. Then we’ll jump-start planning for our fall pilot project in Southern California, where we’ll evaluate three different techniques for measuring fish, all deployed at a time when sardines are abundant in California.
•  Daylight vs. night time photography
•  LIDAR (Light Detection and Ranging): an optical remote sensing technology that measures properties of scattered light to find range and/or other information of a distant target, which can “see” 50 meters underwater
•  Hydroacoustics: utilizing SONAR technology, hydroacoustics is most commonly used for detection, assessment, and monitoring of underwater physical and biological characteristics

Sardine Research Update

Boats, planes and our stalwart research team have been standing at the ready since the close of the directed fishery in July, waiting for Mother Nature to cooperate. And so far the weather gods have been less then helpful in the Northwest and Northern California down to Point Conception.

But the southland has seen clear skies, and we’ve taken advantage of that, as Jeff Luboff and Devin Reed – our southern pilot team – have spotted fish, set boats and photographed 10 successful point sets so far with our southern Experimental Fishing Permit (EFP) vessels: Nick Jurlin on the FV Eileen, Robert Terzoli on the FV Maria T, and Neil Guglielmo on the FV Trionfo.

Schools ranged from five to about 45 tons and represented a nice range of sizes and maturities as well, for a total of nearly 200 mt sardines captured of the approximately 1,050 mt allocated to the Southern CA survey area.

Good job guys!

Grateful thanks also to our southern research team — including Dr. Doyle Hanan, field coordinator for the entire CA project, his son Zach who is overseeing southern operations and the San Pedro markets processing the fish, Tri-Marine and State Fish Co. and their sampling crews.

Monterey EFP vessels King Philip, Sea Wave and El Dorado and their captains, Anthony and Andy Russo and Frank Aliotti, as well as Monterey Fish Company – which will process the northern CA fish – are standing by patiently, waiting for the high sign to conduct point sets. We’re hoping and praying for a weather break soon!

We’ve learned that the coast cleared in the Northwest and pilots resumed transects in WA and OR on Thursday Aug. 18. Our pilot Geno Zandona also completed about 4.5 transects in far Northern CA. And if even part of the northern coast clears, our pilots will continue transects on down the coast over the weekend.

Additionally, we can continue this research project right up to September 15 – the beginning of the fall directed fishery – which allows another three full weeks plus a few days. The weather is typically better and fish are more abundant in Monterey in September; so we still have hope!!

We’ll be filing weekly updates on this blog, along with video and photos to illustrate the action.

Please stay tuned.

Assemblymember Wesley Chesbro Asks for Six-Month Delay in MLPA Implementation

“Citing concerns about how the Marine Life Protection Act is being implemented on the North Coast, Assemblymember Wesley Chesbro (D-North Coast) has asked California Resources Secretary Lester Snow to delay the process for at least six months to ensure that environmental protection is balanced with traditional access rights. Chesbro made the request in a recent meeting with Snow.”

The Wall Street Journal Reports on Marine Life Protection Act

In today’s edition of The Wall Street Journal, reporter Jean Guerrero reports on the Marine Life Protection Act.

Among other things, she notes that, “Many fishermen say they don’t understand the need for more marine protected areas in waters off California, where the ocean is already highly regulated.”
