Abstract
This project was undertaken to evaluate the fecundity, fertility, hatch success and larval survival of fish (Florida pompano) upon exposure to chemically enhanced water accommodated fraction (CEWAF) of south Louisiana crude oil. Hence, fish were exposed to CEWAF in tanks for a specified period of time and evaluated in terms of percentage of eggs that were fertilized, the percentage of fertilized eggs that hatched and the percentage of survival. Protein content and reproductive steroid concentrations were also measured.
Purpose
To determine reproductive success after acute exposure to CEWAF of south Louisiana crude oil and Corexit 9500.

Supplemental Information
The file "Test 208 Reprofxn_SpawnHatch R4.x267.0000077 submitted 3.1.19.xlsx": Contains multiple worksheets that detail the experimental setup and conditions (Test Conditions table, Tank Descriptions, T208 Sample Key), how stock and diluted CEWAF were made (Stock CEWAF Preparation, CEWAF Dilution Preparation respectively), the concentrations of steroids and proteins as determined by the ELISA diagnostic kit (Elisa), the description of fish in terms of gender, weight and length (HSI_GSI), and the % fertilization, % hatched, and % survival after exposure to CEWAF (CEWAF_Hatch & Survival and Control_Hatch & Survival). The worksheet “T208 Sample Key”: Collected Date (MM/DD/YYYY), Field ID, Matrix, MML Number, Species, Gender, Weight (g) and Length (cm). The worksheet “Test Conditions table”: Contains information regarding the setup of the experiments in terms of species, life stage of species, exposure type, renewal frequency, number of replicates per treatment, description of treatments, and aeration. The worksheet “Tank Descriptions”: Tank (name of tank), # Female and # Male (refer to numbers of females and males), Treatment (type of experiment- either a control or actual experiment), Start Date and End Date (beginning and conclusion of experiment; MM,DD,YYYY), Time Spike A and Date Spike A (time and date of initial addition of chemicals; MM,DD,YYYY; MM:SS), Time Spike B and Date Spike B (time and date of second addition of chemicals; MM,DD,YYYY; HH:MM). The worksheet “Stock CEWAF Preparation”: Date and Start time (referring to when CEWAF was made; DD/MM/YYYY; HH:MM), Carboy ID, Oil (the amount of oil added to mixture, g), Corexit (the amount of Corexit added to mixture, g) and Seawater (quantity of seawater L). The worksheet “CEWAF Dilution Preparation”: Date and Start time (referring to when dilution was made; DD/MM/YYYY; HH:MM), Carboy ID (referring to carboys used in transfer), Stock and Final volume (L). The worksheet “Elisa”: Spawning tank (tank Id), Treatment (control or experimental), Field ID (ID for fish), Rep 1 and Rep 2(referring to replicate measurements of proteins and steroids in pg/ml or ng/ml), MML (ID code), Average (mean measurement in pg/ml or ng/ml), and Dilution Factor, Final Conc. (corrected concentration obtained by taking dilution into account, ng/ml). The worksheet “HSI_GSI”: Treatment (control or CEWAF), Field ID (notation to identify fish), Collected Date (date of experiment), Gender, Weight (g), Fork Length (cm), Liver weight (g), HSI (%) Gonad weight (g), and GSI (%). HSI (%) and GSI (%) refer to the percentage of weight occupied by liver and gonad respectively. The worksheets “CEWAF_Hatch & Survival” and “Control_Hatch & Survival”: Treatment (control or CEWAF), Tank ID (identifier), Spawn (Y/N), Date, Status (whether fish survived, fertilized or stocked), Total Eggs (quantity of eggs), Fertilization %, Hatch % , Survival Day 1 (%), and Survival Day 3 (%).|All Florida pompano used in the experiment were spawned and reared at Mote's Aquaculture Research Park. Details on how stock solutions of CEWAF and dilutions were made are provided in the data file itself. Concentrations of proteins and reproductive steroids were assessed with the use of ELISA kits (Cusabio E2, Biosense Vtg).||||
