title: [Spawning induced by injection of progesterone into the teleost crenimugil labrosus (risso, 1826) in a brackish milieu (author's transl)].
abstract: 10 In the euryhaline fish Crenimugil labrosus, complete oocyte maturation does not occur in a brackish milieu. 20 The injection of progesterone induces complete maturation in 30% and 14% salinities, allowing larvae to be formed after artificial fertilization of the eggs. 30 The same result is obtained with hypophysectomized animals: thus the pituitary is not involved in this maturation.
