Abstract
We studied the larval growth of three wild populations (AT = Atlantic, WM = West Mediterranean and EM = Est Mediterranean) of European seabass in three thermal regimes (rAT = Atlantic regime, rWM = West Mediterranean regime and rEM = Est Mediterranean regime) since the hatching until an average weight of 1.5 g. These three thermal regimes aimed to mimic the natural temperature curves of the three populations. The aims of this study are to understand and model the robustness of European seabass in the context of global warming.

Description of the data and file structure
File: dta_design_expe_temperature_v2.txt
This file contains the temperature data of the desired and realized temperature curves for the three thermal regimes since 0 day post-hatching (dph) until the end of the experiment for each thermal regime.
column descriptor:
- Dph = day post-hatching
- Type_env = thermal regime desired (rAT, rWM, rEM, rAQUA) et realized (rAT_real, rWM_real, rEM_real, rAQUA_real)
- Temperature = Daily temperature (°C)
File: dta_growth_paper_dph20_v2.txt
This file contains the body length of the three populations of larvae reared, separated between 0 dph and 20 dph. The lengths were measured just before the transfer of the fish in the three thermal regimes at 20 dph.
column descriptor:
- dph = day post-hatching
- Room = Room of the rearing during 0 and 20 dph
- Population = Information of the population origin of the fish
- Tank = There were 2 tanks per population
- Individual = Number of the sampled fish
- Length = Body length of the fish (mm)
File: dta_larval_length_weight_fin.txt
This file contains the lengths of all the samplings in the three thermal regimes at different dph and the scoring of the different studied developmental stages.
column descriptor:
- Date = date of the samplings
- dph = day post-hatching
- Developmental_Stages = Description of the samplings
- Thermal_regime = thermal regime where the sampling was performed (rAT, rWM and rEM)
- Population = Information of the population origin of the fish measured (AT, WM or EM)
- Tank = tank where the sampling was performed (There were 4 tanks per thermal regime)
- Individual = Number of the sampled fish
- Length = Body length of the fish (mm)
- Sire = sire name of the sampled fish
- Dam = dam name of the sampled fish
- Pheno_dev = Phenotype of the studied developmental stages (number of caudal ray or absence(0)/presence(1) of the other stages)
- Type_fin = Description of the studied developmental stages
File: dta_mean_tank_random_thermal_regime_v2.txt
This file comes from dta_larval_length_fin.txt file. This file contains the average lengths of the fish in each tank per thermal regime for each developmental stages.
column descriptor:
- dph = day post-hatching
- Developmental_Stages = Description of the samplings
- Thermal_regime = thermal regime where the sampling was performed
- Tank = tank where the sampling was performed
- n = number of fish on which we have estimated the mean
- Length = Average length of the tank (mm)
- se = standard error
File: dta_*survival_*tank_thermal_regime_larval_v2.csv
This file contains the survival of each tank in each thermal regime at two time points. The first is between 20 dph and an average body length of 23.4 mm in all thermal regimes. The second is between 23.4 mm and the end of the experiment.
column descriptor:
- Tank = tank where the survival was estimated
- Zone = One of the three thermal regimes
- Survival_1 = Estimated survival during the first period
- Survival_end = Estimated survival during the second period
- Nombre_real_1 = Number of fish remaining at the end of the first period
- Nombre_real_end = Number of fish remaining at the end of the second period
- Length_1 = Average length of the fish remaining at the end of the first period (mm)
- Length_end = Average length of the fish remaining at the end of the second period (mm)
File: dta_larval_length_mean_dam.txt
This file contains an average length of the offspring providing from the same mother in each thermal regime and developmental stages.
column descriptor:
- Developmental_Stages = Description of the samplings
- Thermal_regime = thermal regime where the average was estimated
- Population = Information of the population origin of the dam
- dam = Name of the studied dam
- variable = Description of the studied phenotype in column mean
- n = number of fish on which we have estimated the mean
- mean = Estimated mean of the length of the n fish providing from the same dam (mm)
- se = standard error
- Weight_dam = Dam weight at the time of the crossing (kg)
File: dta_comp_FishNess_natural_larval_growth_v2.csv
This file contains a length comparison of the European seabass larvae between the data of our experimental study and data sampled directly in the sea.
column descriptor:
- Date = time when the sampling was performed
- Zone = location where the sampling was performed
- Length = Average length of the sampling (mm)
