Umbrina roncador (yellowfin croaker) is a nearshore fish that is found from Point Conception in California to Bahia Magdalena in Baja California, Mexico, as well as in the northern part of the Gulf of California (Radford and Walker 1992). Their nomenclature refers to their coloring and their place within the Sciaenidae (croaker) family, which is characterized by the unique drumming noises produced by fish in this family (Pondella et al. 2008). Some of the yellowfin croaker’s distinguishing characteristics are its short chin barbel and its distinctive yellow fins. The majority of the yellowfin croaker’s body is a silver shade with a blue tinge on its back (Skogsberg 1939). Yellowfin croaker grow at a faster rate until three years of age, around when they reach sexual maturity (Pondella et al. 2008) and their lifespan can be as much as 15 years. Female yellowfin croakers reach their adult size faster than the males (Miller et al. 2011) and their reproductive season usually occurs in the summer months (Pondella et al 2008).
