Methods and Sampling: <p><strong>Specimen Collection&nbsp;</strong></p>
<p>Larval rockfish were collected using a 71cm diameter dual Bongo plankton net system with 505 µm mesh nets and equipped with a small CTD to record depth and physical variables during horizontal net tows at a ship speed of 1.5-2.5 knots down to 28.9-36 m depth.</p>
<p><strong>Collection Location Details</strong></p>
<p>This study is carried out within the temperate to subtropical Southern California Bight and surrounding coastal areas between 32° and 35° N, and 117° and 120° W. Specific locations sampled fall within the CalCOFI and CCE-LTER programs quarterly survey grid from lines 76.7 to 93.4 and stations 26 to 55.&nbsp;&nbsp;</p>
<p><strong>Specimen Processing and Measurement Methods&nbsp;</strong></p>
<p>Once the net was retrieved the nets were gently rinsed with saltwater. The content of the cod-ends were immersed in a saltwater ice slurry to hopefully increase retention of gut contents, then concentrated onto a 300 µm mesh sized sieve, transferred into glass jars and preserved in tris-buffered 95% ethanol.</p>
<p>Rockfish larvae were sorted from the samples.161 individuals were selected to represent a range of sample stations and growth stages and measured (standard length, body depth, head length). Rockfish larvae were genetically identified as described in Thompson et al. (2016). The entire digestive tracts of the selected larvae were removed and dissected. Recovered prey items were identified to class or order level and by development stage (when applicable), length and widths were measured of all prey using an eyepiece micrometer, and measurements were converted to mm. Total body length was used for all organisms except copepods, where prosome length was measured instead. Length and width measurements are only given for prey intact enough to allow these measurements to be taken accurately.&nbsp;&nbsp;</p>

RAPID: Understanding the unprecedented anchovy response to warm-water conditions in the California Current

RAPID: Understanding the unprecedented anchovy response to warm-water conditions in the California Current
<p><em>NSF Award Abstract:</em><br />
Like many species of small pelagic marine fish, recruitment and productivity of Northern Anchovy fluctuate by orders of magnitude among years. When abundant, the anchovy support a wide range of marine species, including marine mammals, seabirds and a diverse group of marine fishes. Anchovy, which previously thrived during periods of cool-water temperatures and strong coastal upwelling, are currently booming with abundances far in excess of any historical record, even though the California Current Ecosystem is experiencing an unprecedented marine heat wave. This unexpected occurrence challenges the most basic understanding of the mechanisms driving population dynamics in the species. This project is investigating the effects of trophic relationships on population productivity by capitalizing on the immediate research opportunity afforded by the novel, yet ephemeral, state of a local marine heat wave. Findings from the work are being used to develop a mechanistic model of coastal pelagic fish population dynamics generally, and anchovy dynamics in particular. Funded field and lab work are supporting opportunities for undergraduate training and research, and are generating open-access data that serve the research and teaching/training communities into the future.</p>
<p>This RAPID project augments the scheduled Fall research cruises jointly run by the California Cooperative Oceanic Fisheries Investigation and the California Current Ecosystem Long-Term Ecological Research programs. Together, these programs conduct regional oceanographic surveys that include anchovy spawning grounds and larval nursery areas. The RAPID-augmented sampling is designed to test the emerging hypothesis that anchovy populations are trophodynamically mediated at the larval stage, whereby high recruitment results from increased trophic transfer efficiency from the base of the food web. Larval diets and prey selection analyses are being paired with amino acid compound-specific isotope analysis (δ15N) of the larvae and prey field to generate detailed information on larval trophic ecology. Larval diets and plankton community structure are being related to available data on upwelling and productivity to assess environmental and biological drivers to trophic transfer efficiency. Collectively, these analyses are revealing how food chain length is regulated at the larval level through prey selection, at the prey level through community composition, and at the base of the food chain via coastal upwelling and primary production. Furthermore, this project is establishing whether the current trophic level of anchovy larvae is equal to that of historic population booms and if this is the result of favorable feeding conditions throughout their habitat. Findings from the study are generating a mechanistic understanding of the trophic underpinnings of small pelagic fish population productivity in coastal upwelling systems.</p>
<p>This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.</p>

Bongo Plankton Net System
Bongo Plankton Net System
PI Supplied Instrument Name: Bongo Plankton Net System PI Supplied Instrument Description:Larval fish were collected using a 71-centimeter (cm diameter dual Bongo plankton net system equipped with a small CastAway-CTD. The Bongo was equipped with two 505-micrometer (µm) mesh-size nets and a flowmeter mounted in the center of one of them. Instrument Name: Bongo Net Instrument Short Name:Bongo Net Instrument Description: A Bongo Net consists of paired plankton nets, typically with a 60 cm diameter mouth opening and varying mesh sizes, 10 to 1000 micron. The Bongo Frame was designed by the National Marine Fisheries Service for use in the MARMAP program. It consists of two cylindrical collars connected with a yoke so that replicate samples are collected at the same time. Variations in models are designed for either vertical hauls (OI-2500 = NMFS Pairovet-Style, MARMAP Bongo, CalVET) or both oblique and vertical hauls (Aquatic Research). The OI-1200 has an opening and closing mechanism that allows discrete "known-depth" sampling. This model is large enough to filter water at the rate of 47.5 m3/minute when towing at a speed of two knots.

CastAway-CTD
PI Supplied Instrument Name: CastAway-CTD PI Supplied Instrument Description:Larval fish were collected using a dual Bongo plankton net system equipped with a small CTD to record depth and physical variables during horizontal net tows at a ship speed of 1.5 to 2.5 knots down to 14 to 36 meters (m) depth, depending on bottom depth. Instrument Name: SonTek CastAway-CTD Instrument Short Name:CastAway-CTD Instrument Description: The Sontek CastAway-CTD (manufactured by Xylem) is a handheld castable instrument that provides instantaneous profiles of temperature, salinity, and sound speed. Each cast is referenced with both time and location using its built-in GPS receiver. The CastAway software displays profiles of the casts in addition to mapping the locations of the data collection points. The CastAway-CTD has a 5 Hz response and sampling rate, accurate to 0.1 (PSS-78), 0.05° Celsius.
Conductivity range is 0 to 100,000 µS/cm.
Temperature range is -5° to 45° Celsius.
Pressure range is 0 to 100 decibars.
