information on its anatomic and structural status during ontogeny,
and it can be useful for establishing the functional systemic capabilities
and physiological requirements of larvae for optimal welfare, growth
and survival. Based upon its feeding mode, and analysing the main
morphohistological characteristics of the different organs and systems,
larval development in Atlantic bluefin tuna was divided into four
stages: stage 1: 0–1 dph; stage 2: 2–3 dph; stage 3: 4–10 dph and
stage 4 from 11 dph and around the first month of larval life.
