Embryonic development of the circulatory and respiratory systems of teleost fishes
Abstract
Scope and Method of Study: A survey of the literature was conducted to determine the embryonic development of the circulatory and respiratory system of teleost fishes; including a description of pelagic and demersal eggs, and fertilization of the eggs; origin of the circulatory system from the embryonic mesoderm, and the development of the heart; changes that occur in the circulatory system as organs and appendages develop: origin of the visceral arches and changes produced in the circulatory system as gills develop; development of jaws and tongue, with a description of the oral valves; origin of the gas bladder, and its development in physostomous and physoclistic fishes. Findings and Conclusions: Embryonic development is considered to be the same in all teleost fishes. The differences occur in the time intervals of different stages in development.
