Juvenile Black sea bass winter growth and lipid accumulation under varying food and temperature conditions - Experiment 1 Dataset Description: Methods and Sampling: <p>Juvenile Black sea bass (BSB) were caught on September 3rd (collection 1) and 21st 2021 (collection 2) via beach seine (30 × 2 meters) in Mumford Cove (41° 19' 25"N, 72° 01 '07"W), a shallow protected bay with extensive eelgrass cover in eastern Long Island Sound, USA.</p>
<p><strong>Experiment 1</strong> quantified juvenile BSB growth and lipid accumulation at constant food rations and 3 static temperature treatments. On November 5, 2021, we determined initial total length (TL) and wet weight (wW) on briefly anesthetized specimens (20 milligrams per liter MS-222) and selected 72 juveniles of similar size for the experiment (mean ± SD TL = 70.2 ± 5.5 millimeters (mm), wW = 5.2 ± 1.4 grams (g), 2ⁿᵈ collection). The remainder was euthanized as a baseline sample for subsequent lipid analyses (n = 32, mean ± SD TL = 85.6 ± 10.5 mm, wW = 8.8 ± 2.9 g). Each juvenile was placed into a round 20-liter (L) rearing container equipped with mesh-screened (250-micrometer (µm)) holes and a PVC shelter (15.2 x 3.8 centimeters internal diameter). We randomly placed each rearing container into one of nine 600 L recirculating tanks (8 containers per tank mean maximum stocking density = 0.07 kilograms per cubic meter (kg m⁻³) that were independently controlled for temperature (via LabView®, National Instruments™ triggering heaters or chillers) and assigned to one of three temperature treatments: 6, 12, 19° Celsius (C) (3 tanks per temperature treatment). Initially, all juveniles experienced 20°C for 7 days, then conditions were decreased by 0.5°C per day until target temperatures were reached. To achieve approximately similar cumulative temperature conditions, the total rearing period differed among treatments, i.e., 51 days (19°C treatment, 976 degree days), 71 days (12°C treatment, 936 degree days), and 99 days (6°C treatment, 783 degree days). The photoperiod was gradually decreased from 16L:8D to 9L:15D.</p>
<p><strong>Response traits.</strong> Initial, monthly (Exp2 only), and final measurements of individual fish (TL, wW) were used to calculate total (final – initial), cumulative (end of month – initial), and/or serial (end of month – start of month) growth (e.g., cumulative and serial DTL for month 2 = TL<sub>d61</sub> – TL<sub>d0 </sub>and TL<sub>d61</sub> – TL<sub>d31</sub>), respectively) and average daily growth rates (growth/days in growth interval). Specific growth rates (SGR; % wW per day) were calculated similarly but used ln(wW) at each time period (e.g., 100*[ln(wW<sub>d61</sub>)-ln(wW<sub>d31</sub>)]). Growth efficiency (GE, %) was calculated cumulatively (Exp1, Exp2) and monthly (Exp2 only) as the change in body dry weight (DdW<sub>b</sub>, g) divided by total food consumed (DF, g) during a given time interval. (In Exp2, three GE values &gt; 100% were excluded as outliers). Q₁₀ values (Exp1) were calculated for GR, SGR, and GE between 6-12°C and 12-19°C.</p>
<p>For each experiment, we also determined the lipid, lean, and ash dry weights of each surviving BSB juvenile and those of the baseline samples. Whole specimens were first transferred to -80°C for one week, then freeze-dried at -50°C for one week and re-measured for whole body dry weight (dW<sub>b</sub>, 0.001 g). Dried specimens were then loaded into pre-weighed Alundum medium-porosity extraction thimbles and transferred into a custom-designed Soxhlet apparatus, where they were bathed in petroleum ether for a total of 3.5 hours to extract all metabolically accessible lipids (15-minute cycles of bathing, flushing, and ether replacement). After extraction, thimbles were dried overnight at 60°C and re-weighed to determine DdW, which equaled the total lipid content (dW<sub>Lipid</sub>, milligrams (mg)) of each specimen after accounting for any tissue loss during transfer from vial into thimble. Thimbles were then placed in a muffle furnace for 4 hours at 550°C and re-weighed, with DdW during this second step corresponding to a fish's lean mass (dW<sub>Lean</sub>, mg), again after accounting for any tissue loss during transfer from vial into thimble. The difference between the final weight and the pre-weighed empty thimble equaled ash (dW<sub>Ash</sub>, mg), i.e., the inorganic fraction of each individual.</p>

Collaborative research: Understanding the effects of acidification and hypoxia within and across generations in a coastal marine fish
<p><em>Description from NSF award abstract:</em><br />
Coastal marine ecosystems provide a number of important services and resources for humans, and at the same time, coastal waters are subject to environmental stressors such as increases in ocean acidification and reductions in dissolved oxygen. The effects of these stressors on coastal marine organisms remain poorly understood because most research to date has examined the sensitivity of species to one factor, but not to more than one in combination. This project will determine how a model fish species, the Atlantic silverside, will respond to observed and predicted levels of dissolved carbon dioxide (CO2) and oxygen (O2). Shorter-term experiments will measure embryo and larval survival, growth, and metabolism, and determine whether parents experiencing stressful conditions produce more robust offspring. Longer-term experiments will study the consequences of ocean acidification over the entire life span by quantifying the effects of high-CO2 conditions on the ratio of males to females, lifetime growth, and reproductive investment. These studies will provide a more comprehensive view of how multiple stressors may impact populations of Atlantic silversides and potentially other important forage fish species. This collaborative project will support and train three graduate students at the University of Connecticut and the Stony Brook University (NY), two institutions that attract students from minority groups. It will also provide a variety of opportunities for undergraduates to participate in research and the public to learn about the study, through summer research projects, incorporation in the "Women in Science and Engineering" program, and interactive displays of environmental data from monitoring buoys. The two early-career investigators are committed to increasing ocean literacy and awareness of NSF-funded research through public talks and presentations.</p>
<p>This project responds to the recognized need for multi-stressor assessments of species sensitivities to anthropogenic environmental change. It will combine environmental monitoring with advanced experimental approaches to characterize early and whole life consequences of acidification and hypoxia in the Atlantic silverside (Menidia menidia), a valued model species and important forage fish along most of the US east coast. Experiments will employ a newly constructed, computer-controlled fish rearing system to allow independent and combined manipulation of seawater pCO2 and dissolved oxygen (DO) content and the application of static and fluctuating pCO2 and DO levels that were chosen to represent contemporary and potential future scenarios in productive coastal habitats. First CO2, DO, and CO2 × DO dependent reaction norms will be quantified for fitness-relevant early life history (ELH) traits including pre- and post-hatch survival, time to hatch, post-hatch growth, by rearing offspring collected from wild adults from fertilization to 20 days post hatch (dph) using a full factorial design of 3 CO2 × 3 DO levels. Second, the effects of tidal and diel CO2 × DO fluctuations of different amplitudes on silverside ELH traits will be quantified. To address knowledge gaps regarding the CO2-sensitivity in this species, laboratory manipulations of adult spawner environments and reciprocal offspring exposure experiments will elucidate the role of transgenerational plasticity as a potential short-term mechanism to cope with changing environments. To better understand the mechanisms of fish early life CO2-sensitivity, the effects of temperature × CO2 on pre- and post-hatch metabolism will be robustly quantified. The final objective is to rear silversides from fertilization to maturity under different CO2 levels and assess potential CO2-effects on sex ratio and whole life growth and fecundity.</p>

Automated Larval Fish Rearing System (ALFiRiS)
Automated Larval Fish Rearing System (ALFiRiS)
PI Supplied Instrument Name: Automated Larval Fish Rearing System (ALFiRiS) Instrument Name: Automated Larval Fish Rearing System Instrument Short Name:ALFiRiS Instrument Description: The Automated Larval Fish Rearing System (ALFiRiS) was self-designed and assembled in the Rankin Lab at the University of Connecticut Avery Point. It consists of a 3 x 3 array of recirculating units (600 liters/150 gallons) that have independent computer-control over their temperature, oxygen, and pH conditions.
The system was designed to sequentially monitor tank conditions via industrial-grade oxygen and pH sensors (Hach) and then control gas solenoids (air, N2, CO2) to maintain and modulate environmental conditions. The system can apply static as well as fluctuating conditions on diel and tidal scales. Computerized temperature control allows simulating heatwaves and other non-static thermal regimes.
