Out of 86 pairs, 36 pairs produced 149 hatchlings (day 0) from which 35 pairs raised 108 fledglings (day 17), from which 33 pairs raised 96 offspring until independence (day 35).
To this end, zebrafish hatchlings (5 d post-fertilization) were exposed to 0, 0.3, 3 and 30 µg/L microcystin-LR (MC-LR) for 90 d until they reached sexual maturity.
In the present study, zebrafish hatchlings (5 d post-fertilization) were exposed to 0, 0.3, 3 and 30 μg/L MC-LR for 90 d until reaching sexual maturity.

Irradiated fish produced fewer eggs per day (p=0.03); had a lower percentage of viable eggs (p=0.04), and produced a lower percentage of hatchlings (p=0.05).
Field studies of reptiles commonly show that earlier hatching can increase the survival rate of hatchlings [30], [31], [32].
Prior to hatch, maternal IgY is absorbed into embryonic circulation [16], where it confers passive immunity to immunologically immature hatchlings [4], [6], [7], [10], [11], [17], [20].
Although a predominantly herbivorous omnivore [51], Birgus is known to prey on vertebrates, including tortoise and turtle hatchlings [53], [97] and even rats [98].
Furthermore, the "leftovers" of these defenses are in fact storage proteins consumed at a later time by developing embryos and hatchlings [5].
For the common snapping turtle Chelydra serpentina chemicals including organochlorine pesticides, polychlorinated biphenyls and mercury were identified as main causes of developmental abnormalities in both embryos and hatchlings [7], [17].
