King Mackerel - Life History

Life History

Eggs and sperm are shed into the sea and their union is by chance. Depending on size, a female may shed from 50,000 to several million eggs over the spawning season. Fertilized eggs hatch in about 24 hours. The newly hatched larva is about 0.1 inches (2.5 mm) long with a large yolk sack. Little is known about king mackerel in their first year of life. Yearling fish typically attain an average weight of 3 to 4 pounds (1.4–1.8 kg) and a fork length of 25 inches (60 cm). At age seven, females average 21 lb (9.5 kg), males 11 lb (5 kg). King mackerel may attain 90 lb (40 kg), but any over 15 pounds (7 kg) is almost certainly a female.

Famous quotes containing the words life and/or history:

    Still we live meanly, like ants; though the fable tells us that we were long ago changed into men; like pygmies we fight with cranes; it is error upon error, and clout upon clout, and our best virtue has for its occasion a superfluous and evitable wretchedness. Our life is frittered away by detail.
    Henry David Thoreau (1817–1862)

    The steps toward the emancipation of women are first intellectual, then industrial, lastly legal and political. Great strides in the first two of these stages already have been made of millions of women who do not yet perceive that it is surely carrying them towards the last.
    Ellen Battelle Dietrick, U.S. suffragist. As quoted in History of Woman Suffrage, vol. 4, ch. 13, by Susan B. Anthony and Ida Husted Harper (1902)
