Do zebra fish go through embryonic stages?
development of the embryo of the zebrafish, Danio (Brachydanio) rerio. We define seven broad peri- ods of embryogenesis-the zygote, cleavage, blas- tula, gastrula, segmentation, pharyngula, and hatching periods.
How long does it take for a zebrafish embryo to develop?
Zebrafish develop rapidly from a one-cell zygote that sits on top of a large yolk cell. Gastrulation begins approximately 6 h post fertilization, hatching at 2 days as a free-swimming larvae. Zebrafish reach sexual maturity around 3 months of age and can live for up to 5 years.

What are the stages in life cycle of zebra fish?
The zebrafish lifecycle is divided into four major periods: Embryo, larva, juvenile, and adult. The full life cycle from fertilized egg to adult is a quick 90 days.
What is zebrafish embryo?
The zebrafish embryo offers unmatched opportunities to identify bioactive molecules in the context of an intact, complex organism. This is particularly relevant in the areas of stem cell research, as these cells can best be studied in their natural environment.
What are the stages of fish?
Life Cycle of a Fish:
- The Egg – Stage 1 –
- The Larvae – Stage 2 –
- The Fry – Stage 3 –
- The Juvenile – Stage 4 –
- The Adult – Stage 5 –
- The Spawning – Stage 6 –
What are the four stages of embryonic development?
Briefly, embryonic development have four stages: the morula stage, the blastula stage, the gastrula stage, and the neurula stage. Prior to implantation, the embryo remains in a protein shell, the zona pellucida , and undergoes a series of cell divisions, called mitosis.
What is the proper order of embryonic development?
The stages of embryonic development in the correct order; 1. egg fertilized to form a zygote 2. cell division in a zygote to form a morula 3. cell division to form a blastocyst 4. differentiation of cells in the blastocyst 5. development of tissues 6. development of organs
What is process starts at the embryonic period?
Fertilization. Fertilization is the union of the female gamete (egg) and the male gamete (spermatozoa).
What does embryonic development begin with?
Embryonic development starts with the fertilization of the egg cell (ovum) by a sperm cell, (spermatozoon).
