Egg Development of Paralichthys orbignyanus (Valenciennes, 1839)

Brazilian Archives of Biology and Technology, 2005
Eggs of the Southern Brazilian flounder Paralichthys orbignyanus were obtained through spawning induction and reared in laboratory. The eggs released were free-floating or pelagic.

Blastopore closure at high and low temperatures.

, 2014
(A) Upper: vegetal view of an embryo showing the blastopore soon after the start of dorsal superficial involution. Lower left: kymograph of blastopore closure at 26°C, taken along the yellow line from the dorsal side to the ventral side, showing the ...

Large, long range tensile forces drive convergence during [PDF]

, 2018
Indirect evidence suggests that blastopore closure during gastrulation of anamniotes, including amphibians such as Xenopus laevis, depends on circumblastoporal convergence forces generated by the marginal zone (MZ), but direct evidence is lacking.

Egg quality markers in domesticated broodstock of Atlantic halibut (Hippoglossus hippoglossus) with relevance for optimization of hatchery protocols

Frontiers in Aquaculture
IntroductionCommercial production of Atlantic halibut (Hippoglossus hippoglossus) has many obstacles, such as low and highly variable egg quality and survival rates during early developmental stages.

A novel role for MAPKAPK2 in morphogenesis during zebrafish development.

PLoS Genetics, 2009
One of the earliest morphogenetic processes in the development of many animals is epiboly. In the zebrafish, epiboly ensues when the animally localized blastoderm cells spread, thin over, and enclose the vegetally localized yolk.

Dynamics of Size and Shape Variation During Embryonic Development in the Balkan Crested Newt

Journal of Experimental Zoology Part B: Molecular and Developmental Evolution, EarlyView.
Morphological variance in Triturus ivanbureschi embryos fluctuates during the tailbud phase, coinciding with developmental arrest caused by the balanced lethal system. Prehatching embryos show uniform variance. Our study reveals dynamics of morphological variability during early development and provides a baseline for further studies.

Rescue of pkdcc1Mo and pkdcc2Mo phenotype by JNK and dnJNK, respectively.

, 2015
(A- G) Four cell stage embryos were injected dorsally with coMo (A), pkdcc1Mo (B-D) or pkdcc2Mo (E-G) and incubated until blastopore closure. The pkdcc1Mo phenotype (delay in blastopore closure) was rescued by injection with JNK mRNA (C) but not with ...

Developmental Fates of Progenitor/Undifferentiated Cells With Histone Trimethylation Tags in the Stony Coral, Acropora tenuis

Development, Growth &Differentiation, Volume 68, Issue 7, September 2026.
In the stony coral, Acropora tenuis, embryos and larvae have progenitor/undifferentiated cells. Undifferentiated‐like cells differentiate into the pharyngeal stomodeum at an early larval stage, and nerve progenitors possess the dual potential to differentiate into nerve cells and vacuolated hyaline cells, depending on the oral‐aboral position ...

Early and Larval Development of the Marine Species Grey Triggerfish (Balistes capriscus, Gmelin, 1789) and the Use of Different Organisms as First Food Sources

Aquaculture, Fish and Fisheries, Volume 6, Issue 3, June 2026.
ABSTRACT The aim of this study was to provide an initial description of the embryology and larval development of Balistes capriscus species obtained from natural spawning in captivity. The study also aimed to assess the stocking density and the impact of offering four types of live food as the initial feed during the larviculture phase. Observations of
