Abstract

BackgroundMahi‐mahi (Coryphaena hippurus) is a commercially and ecologically important fish species that is widely distributed in tropical and subtropical waters. Biological attributes and reproductive capacities of mahi‐mahi make it a tractable model for experimental studies. In this study, life development of cultured mahi‐mahi from the zygote stage to adult has been described.ResultsA comprehensive developmental table has been created reporting development as primarily detailed observations of morphology. Additionally, physiological, behavioral, and molecular landmarks have been described to significantly contribute in the understanding of mahi life development.ConclusionRemarkably, despite the vast difference in adult size, many developmental landmarks of mahi map quite closely onto the development and growth of Zebrafish and other warm‐water, active Teleost fishes.

Highlights

Coryphaena hippurus, known as the common dolphin fish or mahi-mahi,[1] is a highly migratory epipelagic fish distributed in the world's tropical and subtropical waters, where temperatures are typically between 25C and 30C.2–4
During the last few decades, mahi has become an emergent model for examining population genetics,[10] developmental physiology,[11,12] metabolic responses,[13] nutritional physiology,[7] egg and larval performance over time,[14] and climate change effects.[15,16]
Mahi have been studied extensively regarding the impact of environmental toxicants.[17,18,19,20,21,22,23,24,25,26,27,28,29,30]. The emergence of this model fish has been accelerated by the need to develop more sophisticated scientific approaches for understanding the impact of environmental stressors, especially the impacts of the Deepwater Horizon Oil spill in 2010

Introduction

Coryphaena hippurus, known as the common dolphin fish or mahi-mahi,[1] is a highly migratory epipelagic fish distributed in the world's tropical and subtropical waters, where temperatures are typically between 25C and 30C.2–4 Mahi-mahi (hereafter “mahi”) is economically important for recreational and commercial fisheriesDevelopmental Dynamics. 2019;248:337–350.wileyonlinelibrary.com/journal/dvdy throughout this species' global range.[5]. Urea transporter genes begin their expression.[42] At 22 hpf (SL = 2.6-2.8 mm; 26 somites; Figure 1P), the onset of the heartbeat begins with irregular peristaltic movements, which closely resemble those of the Zebrafish embryo, where heartbeat occurs at ~24 hpf.
