attribute NC_GLOBAL acquisition_description String Permits:\u00a0All protocols and experiments, described below, followed
institutional guidelines and were approved by the University of Hawaii
Institutional Animal Care & Use Committee (IACUC protocol number 2099).

Experimental design:\u00a0We set three larval fish age-classes of the
clownfish, Amphiprion ocellaris (early: 1 to 5 days post-hatch [dph]; mid: 6
to 9 dph; and late: 11 to 14 dph) against three developmental stages of the
copepod prey, Bestiolina similis (nauplii: NIII-NIV stages; copepodites: CII-
CIII stages; and adults: CVI stage). The choice of developmental stages
provided a range in prey size (length: ~100 to 500 \u00b5m; McKinnon et al.,
2003), mechanosensitivity, and escape performance (Buskey et al., 2017). We
designed the experiment to quantify how strike posture changed through larval
development (and size: ~4 to 8 mm total length; Jackson and Lenz, 2016), while
also assessing the effect of a prey\u2019s stage on its predator\u2019s

Larval fish-rearing conditions: The experiments used larval clownfish lab-
reared over their two-week planktonic phase. Their rearing, the culturing of
copepod prey, the experimental apparatus and protocols, and the high-speed
video recording and analysis software have been described previously (Robinson
et al., accepted). Briefly, up to 200 recently hatched larvae were raised in a
30-L seawater aquarium kept at 24-26\u00b0 C on a 12:12 L:D light cycle. They
were fed twice daily on a mixed diet of rotifers (Brachionus plicatilis) and
different developmental stages of another calanoid copepod (Parvocalanus
crassirostris). Different prey were used for daily feeding than for
experiments so that fish were exposed to a novel prey type during their trial,
thus avoiding complications arising from learned feeding behavior and
laboratory acclimation.

Behavioral observations and video set-up:\u00a0For the experiments, two larvae
that had been kept without food for 4 to 6 hours were placed into a circular
observation chamber of 20 cm diameter, filled with seawater to a depth of 2 cm
containing copepods at a density of 0.2 to 0.7 individuals ml-1. Experimental
trials lasted for one hour or less and no fish larvae were used in more than
one trial. Interactions between fish larvae and copepods were recorded at 500
frames per second (fps) using a Photron FastCAM SA4 video camera mounted above
the observation chamber with dark-field illumination. The field-of-view of the
camera was 35 x 35 mm with an image resolution of 1024 x 1024 pixels.

Data analysis:\u00a0Predatory attacks were analyzed to characterize the
temporal sequence up to and through the strike of fish larvae on different
copepod developmental stages. We quantified the duration (in sec) of the
approach phase of the fish, defined and described in Robinson et al.
(accepted) as beginning when the tail stopped beating and started to bend to
the left or right, and ending at t0. Thirty-seven successful captures (n = 37)
by fish larvae were analyzed using the Fiji software package built on ImageJ
(v1.51) (Schindelin et al., 2012) to digitize the changing body shape of the
fish as it prepared for and initiated the strike. For each interaction, we
established a temporal reference (t0) as the image just prior to the opening
of the fish\u2019s mouth. Twenty-five frames, including 12 frames before and
12 frames after t0, were then extracted and the posture of the fish larva was
characterized frame-by-frame. Twelve frames (24 ms) before t0, labeled as
t-24, was chosen as a standardized interval that captured the final approach
phase of fish in our trials, which ranged from 28 to 1130 ms preceding t0. The
median speed during the final frame of approach (t-2) was 0 mm s-1. Therefore,
fish were most often motionless at this time interval, meaning that all motion
involved in the acceleration of the strike occurred after t0. Twelve frames
after t0, labelled as t+24, was chosen as a standardized interval as it always
included peak strike speed, copepod capture, and subsequent deceleration of
the fish. Starting with t-24 and continuing every other frame up to and
including t+24, we digitized the x,y coordinates of 12 points along the
central axis of the larva. Because its position with respect to the fish did
not change, we used a small pigment spot located at the narrowest point
between the eyes as a spatial reference for each frame (origin at x=0, y=0).
The position of the copepod in each frame was also digitized to obtain the
change in distance over time between fish and copepod.\u00a0

We quantified the relative curvature of the body and caudal fin during the
larva\u2019s initial lunge, frame-by-frame from t0 to t+8 (8 ms, i.e., 4
frames after t0). To do so, we used the oval tool in Fiji to place a circle
within the curl of the tail. The \u201cfit circle\u201d and
\u201cmeasure\u201d commands were then used to calculate the area (A) of the
circle. From the circle\u2019s area, we derived the reciprocal radius, r -1 =
\u221a(\u03c0 / A) as a metric of relative curvature of the larva\u2019s
caudal fin, with greater values being more curved and lesser values being less
curved. The measurement of reciprocal radius became less reliable as an
estimate of curvature after t+8 because the tails of most fish began to curve
in the opposing direction, making the inscribed circle too large to measure.
We therefore employed another relative measure of curvature, the straight-line
distance between the tip of the tail and the narrowest point between the eyes
(chord length), divided by the length of the fish when its body was straight
(fish length), also measured between the tip of the tail and origin/pigment.
These normalized distances (chord length-to-fish length ratio, or CVF)
approached 1 when the fish was straight and were decreasing fractions of 1
when the fish was increasingly bent into a J-like posture. To measure speed of
the fish during its predatory lunge (in mm s-1), we tracked the changing
position of the pigment between its eyes from t-4 to t+20 (4 ms, i.e., 2
frames before t0 and 20 ms, i.e., 10 frames after t0, respectively) and
divided the frame-by-frame distance travelled by the time elapsed between
frames. In addition, the distance from the spot between the eyes and the tip
of the mouth was measured at t0 and t+8 to determine the contribution of jaw
extension to prey capture.\u00a0

attribute NC_GLOBAL projects_0_description String Description from NSF award abstract:
This study will experimentally elucidate the dynamics of predator evasion by different species and life stages of copepod responding to a model larval fish predator. The PIs will use standard and high-speed videographic and cutting-edge holographic techniques. Predator-prey interactions within planktonic communities are key to understanding how energy is transferred within complex marine food webs. Of particular interest are those between the highly numerous copepods and one of their more important predators, the ichthyoplankton (the planktonic larval stages of fishes). The larvae of most fishes are planktivorous and heavily dependent on copepods for food. In general, evasion success increases with age in copepods and decreases with the age of the fish predator. How this plays out in detail is critical in determining predatory attack outcomes and the effect these have on predator and prey survival. To address this problem, different copepod developmental stages will be tested against several levels of predator competence, and the results examined for: 1) the success or failure of attacks for different combinations of predator and prey age class; 2) the kinematics (reaction latencies and trajectory orientation) for escape attempts, successful and unsuccessful, for different age classes of copepod; 3) the hydrodynamic cues generated by different ages and attack strategies of the predator and the sensitivity of different prey stages to these cues; and 4) the success or failure of the predatory approach and attack strategies at each prey stage. The data obtained will be used to inform key issues of zooplankton population dynamics. For the prey these include: predator-evasion capabilities and importance of detection ability, reaction speed, escape speed, escape orientation, and trajectory irregularity; for the predator they are: capabilities and importance of mouth gape size, stealthiness, hydrodynamic disturbance production, and lunge kinematics.
