Embryonic development and sensitive stages of Atlantic salmon
2024年1月30日 · The normal embryonic development was recorded through pictures from fertilization to hatching. Since salmon eggs have a thick eggshell making it difficult to observe the embryo, different concentrations of acetic acid (5–10% in …
(PDF) Embryonic development and sensitive stages of Atlantic salmon …
2023年10月1日 · The normal embryonic development of Atlantic salmon eggs was described and illustrated from fertilization to hatching. Additionally, sensitivity based on acute mortality 7 days after mechanical...
Maturation in Atlantic salmon (Salmo salar, Salmonidae): a
2021年6月7日 · We summarize the current state of knowledge: 1) maturation in Atlantic salmon takes place over the entire life cycle, starting as early as embryo development, 2) variation in the timing of maturation promotes diversity in life history strategies, 3) ecological and genetic factors influence maturation, 4) maturation processes are sex-specific ...
Inside the egg, the developing embryo feeds from its yolk sac and obtains oxygen through the egg membrane, through which the oxygen passes from the running water flowing through the gravel of the stream or lakebed. The eggs can smother if the gravel is covered with silt or if the water flows too slowly and stagnates.
The embryology of the Atlantic Salmon (Salmo salar Linnaeus)
2011年4月13日 · We evaluate the usefulness of gill rakers as a post-hatch developmental marker in salmon by tracking development in undisturbed and stressed yolk-bearing salmon embryos.
Simplified Timeline of Atlantic Salmon Embryonic Development
2023年11月8日 · In this regard, the study meticulously detailed and illustrated the normal embryonic development of Atlantic salmon eggs, from the moment of fertilization to hatching. This comprehensive analysis provides a roadmap of the stages an Atlantic salmon embryo goes through on its way to becoming an adult fish.
Salmonid Embryo Development and Pathology - Semantic Scholar
This chapter provides an overview of fish gametogenesis, fertilization physiology and behavior, and documented embryo development stages and improves quantitative assessment of spawning habitat remediation projects in disturbed habitats. The development of each salmonid egg follows a predetermined course.
Postovulatory maternal transcriptome in Atlantic salmon and …
2019年4月24日 · Until zygotic genome activation, translational activity in a fish early embryo is limited to parentally inherited transcripts only. In this study, we asked whether egg transcriptome is associated with egg quality in Atlantic salmon (Salmo salar), which is capable of storing ovulated eggs in its abdominal cavity for a long time before spawning.
Color Photographic Index of Fall Chinook Salmon Embryonic
2010年7月29日 · Fall Chinook salmon eggs were fertilized in a hatchery environment and sampled approximately every 72 h post-fertilization until 50% hatch. Known embryonic developmental features described for sockeye salmon were used to describe development of Chinook salmon embryos.
SALMOCODE: the Salmon Map of Organs and Cells for the …
2023年9月27日 · SALMOCODE will explore the hypothesis that production conditions during embryonic development of Atlantic salmon can have a negative impact on organogenesis, the initial phase of organ development, roughly between gastrulation and hatching.
