On this basis it was assumed that egg to smolt survival rates per group were identical in all groups and the number of ranched smolts per experimental group was therefore estimated by multiplying the number of initial (hatchery-retained) eyed eggs per group (Table 1) by the overall egg to S1 smolt survival rate (9115 S1 smolts ÷ 12 606 eggs = 0.723).
In addition, gentamicin (GEN) was used at the hatcheries that supplied chicks to conventional poultry houses, and bacitracin, virginiamycin, roxarsone, and salinomycin were used at the breeder facilities that supplied the initial eggs to the hatcheries.
By assessing the FZT metacercariae prevalence in fish from the initial stages of production, namely the hatcheries and nurseries, the study provides knowledge needed for a comprehensive assessment of FZT infection during the entire fish production cycle.
Details of the experiment location and initial set up of family crosses and hatchery procedure can be found in de Eyto et al. (2007).
It may well be that traits providing rapid growth in the hatchery, and hence a large initial size among our released fish, are disadvantageous for survival in the wild.
The study also could not rule out the possibility that initial differences in rearing environments between the local hatchery and wild fish affected the former's fitness performance in the wild (Araki et al. 2007c).
All 10 SNP assays were tested in 58 offspring from three halibut families produced in the commercial halibut hatchery, which were independent from the initial mapping families, and in 36 independent broodstock halibut (18 ♀:18 ♂) originating from the Shetland Isles, Iceland and possibly the Faroe Islands.
Should hatchery fish be allowed only in the initial stages of recolonization, and if so, at what point would they no longer be needed?
The L. vannamei PL stage five (PL5) with average initial weight of 0.45 mg was obtained from a commercial hatchery and stocked at a density of 50 PL L−1.
The overall egg to hatchery 1+ smolt survival rate was estimated at 72.3% (9115 S1 smolts released/12 606 initial eyed eggs).
However, although the loss of diversity in the initial phases of domestication appears to be small, it may become a concern in the long-term maintenance of hatchery populations.

Since I tried Ludwig back in 2017, I have been constantly using it in both editing and translation. Ever since, I suggest it to my translators at ProSciEditing.
