How do they reproduce?
The mating season of the monogamous shovelnose shark is in the summer season. During this time, the males arrive in the shallow waters and estuaries of the ocean and the females follow after a while. The females are ovoviviparous, just like most sharks and rays. This means that fertilization takes place inside the females where the embryos receive all the nutrition from the yolk sac and after nine to 12 months of gestation, they give birth to six to 28 well-developed young ones. The females return to the mating area which is usually along the coasts of Baja and southern California to give birth from June to October.
The juveniles tend to look after themselves and receive no parental care after taking birth. The sexual maturity of shovelnose guitarfish is usually reached when they are seven to eight years old.

According to the International Union for Conservation of Nature (IUCN) Red List, the shovelnose guitarfish conservation status is Near Threatened. Their numbers are quickly diminishing since there is no conservation policy to protect them in the United States and Mexico waters due to scarce information about this species. They were previously rejected from commercial catches but are now retained as part of a regular and small fishery in northern and central California. The shovelnose guitarfish fishery is controlled by NOAA (The National Oceanic and Atmospheric Administration) Fisheries and the Pacific Fishery Management Council (PFMC) through the Pacific Coast Groundfish Fishery Management Plan (FMP).
