Tuna Family
Skipjack Tuna [family Scombridae (Mackerels)]

Tuna include the largest members of the Mackerel family. Unlike those called "Mackerel", tunas have deep flattened bodies. Most have scales only in a few places but that's enough to be kosher. Bluefin Tuna (all varieties) is to be avoided as all Bluefins are critically endangered. Yellowfin, Bonito, Tongal, Skipjack, Bigeye and Albacore are acceptable for eating.

Bonito - [Island Skipjack, Black Skipjack, Kawakawa (Hawaii), Tongol Tuna, Little Tuna, Mackerel Tuna (English); Tulingan (Philippine); Tongkol (Malay); Euthynnus affinis]
Fresh Fish

This small Indo Pacific tuna is found from the east coast of Africa to Hawaii and is an important commercial fish. Unlike the Skipjack proper (Katsuwonus pelamis) it stays fairly close to shore. It can grow to 39 inches and over 30 pounds, but the photo specimen was 19-1/2 inches and 3-1/4 pounds, about typical for Southern California markets. This fish is not currently considered endangered, IUCN Red List status is NE (Not Evaluated).   Details and Cooking.

Bonito / Skipjack Tuna - [Katsuo (sushi); Katsuwonus pelamis]
Fresh Fish

These small tuna can grow to over 43 inches and over 76 pounds, but the photo specimen was 18-1/2 inches and 3 pounds 13 ounces, about average in Southern California markets. Skipjack is found worldwide in tropical and warm-temperate seas but not in the Eastern Mediterranean or Black Sea.

Commercially Skipjack is sold fresh, frozen and canned, with a small amount sold smoked and dried. This fish is not considered endangered. IUCN Red List status NE (Not Evaluated).   Details and Cooking.

Bluefin Tuna - [Kuromaguro, Hon Maguro, Toro (Japan); Thunnus thynnus (Northern / Atlantic) | Thunnus maccoyii (Southern) | Thunnus orientalis (Pacific)]
Fish Drawing

Bluefin Tuna is the most prestigious sushi / sashimi fish in Japan, and the Japanese are eating them to extinction. Bluefins are listed as Critically Endangered in all conservation lists, but the Japanese simply don't care - the scarcer they are the more they'll pay, because the higher the cost of a fish the better it tastes to the Japanese. It has been reported that a single large Atlantic Bluefin can now fetch as much as US $100,000 in the Japanese fish markets. Do not eat this fish, and strongly discourage others from eating it.

Note that "farmed" is not an acceptable alternative, in fact for Atlantic Bluefin (the most threatened) farming, which depends on wild fish captured before reproductive maturity, is a major cause of depletion. For Pacific and Southern Bluefin, there has recently been some success in captive breeding, but this is still in early experimental stages and is in no way able to impact the market at this time.   Drawing from U.S. National Oceanic and Atmospheric Administration = public domain.
