Gonadal Development of Peprilus medius (Peters, 1869) (Perciformes: Stromateidae) from Southeast of the Gulf of California, Mexico

The gonadal development assessment is a fundamental work in researching the reproduction of Peprilus medius, on the way to understand its population dynamics and to achieve a sustainable management of its fisheries. The diagnosis based on morphochromatic features is the quicker, more practical and c...
