Common name: THREADFIN SHAD

Overview:

Threadfin Shad (Dorosoma petenense) are native to the Mississippi and Gulf of Mexico drainages from Indiana and Illinois south to Guatemala. They have been introduced in introduced to Gulf drainages east of the Mississippi River, the Florida peninsula, and California, Oregon an and Washington. They were stocked as a forage fish for popular game fishes throughout California because of their small size and planktivorous, pelagic habits starting in the 1950s and spread northward along the coast. Many consider the intentional introduction of Threadfin Shad successful because they do provide forage for game fish. However, negative impacts include long distance dispersal, colonization of new habitats, tendency for dramatic population fluctuations, die-offs due to cold weather, and competition with larval and juvenile, gamefish and endangered species.
