amplification of pathogens and parasites and subsequent infection of wild fish, as well as between farms. Escape of cultured fish is also a concern, which can have effects on wild stocks in terms of competition, predation, and genetic alterations, depending on vulnerability and robustness. A risk of pollution and habitat effects via nutrient losses and chemical additives always remains, which can cause problems depending on habitat vulnerability and where the farms are in relation to the coast. With effective management of regulations and good farming practices, these problems can be avoided. To address these impacts, the WWF is creating the Seriola and Cobia Aquaculture Dialogue, the purpose of which is to create standards that will minimize the key impacts of Seriola/Cobia aquaculture and move producers towards better performance. This will be done by identifying the key environmental and social impacts associated with the farming of three types of Seriola (S. rivoliana, S. quinqueradiata and S. lalandi) and cobia, and principles established for addressing each impact. Then, criteria will be developed to provide direction on how to reduce each impact. It is open to all stakeholders, including producers and other members of the supply chain, researchers, nongovernmental and governmental organizations, and investors. The standards (finalised late 2011) will be adopted by the Aquaculture Stewardship Council, which will then work with independent, third-party entities to certify farms that are in compliance with the standards. Species Nine recognized species are placed in this genus: Seriola carpenteri F. J. Mather, 1971 (Guinean amberjack) Seriola dumerili (A. Risso, 1810) (greater amberjack) Seriola fasciata (Bloch, 1793) (lesser amberjack) Seriola hippos Günther, 1876 (samson fish) Seriola lalandi Valenciennes, 1833 (yellowtail amberjack) Seriola peruana Steindachner, 1881 (fortune jack) Seriola quinqueradiata Temminck & Schlegel, 1845 (Japanese amberjack) Seriola rivoliana Valenciennes, 1833 (long-fin yellowtail, almaco jack, high-fin jack) Seriola zonata (Mitchill, 1815) (banded rudderfish) Fishbase includes populations of fish similar to S. lalandi in the Northern Hemisphere within that species, but other authorities regard Seriola aureovittata from the North Pacific Ocean around Japan and Seriola dorsalis of the northeastern Pacific as separate, valid species, with S. lalandi being restricted to the Southern Hemisphere.
