Sentence examples for hatchery environment from inspiring English sources

The daylight group was exposed to indoor daylight in the hatchery environment, the red group was exposed to long wavelength light (600 650 nm), the green group was exposed to mid-wavelength light (495 570 nm) and the blue group was exposed to short wavelength light (420 495 nm).

Artificial propagation requires broodstock which, because of the late sexual maturation of American paddlefish, are initially obtained from the wild and brought into a hatchery environment.

Fall Chinook salmon eggs were fertilized in a hatchery environment and sampled approximately every 72 h post-fertilization until 50% hatch.

Otoliths from the smolts reared naturally (n = 30) and those reared in the hatchery environment (n = 30) were also sampled for comparison (during June 2008).

Inadvertent selection associated with the hatchery environment has raised concerns about the preservation of genetic variation in traits associated with fitness in the wilde populations.

In the hatchery environment there were 28 pure wild offspring, 96 hybrids with wild-born mothers, 52 hybrids with hatchery-born mothers, and 80 pure hatchery offspring.

However, the analysis of control otoliths from the smolts in this study found distinct differences between fish reared in the natural and hatchery environments (Table S1).

The large levels of additive genetic variation suggest that natural or artificial selection for a single or optimal morphotype is not strong within these strains, and it is possible that heterogeneity in the natural or hatchery environments (microhabitat, density, food availability, temperature) has selected for and maintained variable morphotypes.

However, their experiments were conducted in hatchery environments and as such the inferences may not hold in the wild (Einum and Fleming 1999).

Because both stocks experienced hatchery environments and were compared against the same wild population, the difference between them is likely to be genetic in origin.

In order to investigate stability in family performance across the physical hatchery environments, Pearson correlations were performed between mean family log10-weight in the hatchery control treatment and the restricted hatchery treatment.
