This isn't quite exact, but 1/4 cup of butter (so a half stick if you're in the US) is 57 grams according to the conversion chart from allrecipes below. So use just a slightly heavy 1/4 cup or 1/2 stick.
Yellowtail, including Yellowtail Jack (Seriol landei), are recognized by a yellow stripe across their body and their yellow tail. Range & Habitat: Yellowtail is caught year round, but more commonly during summer in the Pacific Coast and the Sea of Cortez. They are caught primarily with hook and line, and their average weight is 10 to 20 lbs.
Yearling bucks average 150 pounds, while does of the same age average about 20 percent less, or about 120 pounds. Some older bucks weigh 200 pounds or more when field dressed (about 250 pounds live weight) and the heaviest Nebraska whitetail on record was 287 pounds field dressed (about 355 pounds live weight). A buck fawn has bumps on his skull where antlers will grow when he is older.
