It is still unclear about the timing and location of spawning of Sphyraena barracuda. Some research reports that they spawn in the spring. Others claim that they spawn in association with particular phases of the moon. Still others claim that great barracudas spawn throughout the year with the exception of the winter months when it is cooler. It may be that great barracudas show different spawning patterns in different areas of the world. Overall, the picture of spawning patterns in great barracudas is incomplete (Paterson 2000).
Great barracuda do not care for their fertilized eggs. They are left to drift out into the ocean and eventually take form (Paterson 2000). When the fish spawn they enter shallow waters such as estuaries. The larvae hatches and seeks shallow weedy areas on the margins of clear-water estuaries. When the larvae reach a length of about 80mm they move to the deeper waters of adjacent reed beds. At about 300mm they will move to open waters and eventually they will move out of the estuaries completely at about 500mm in length (Blaber 1997). (Blaber, 1997; Paterson, 2000)
