    Method according to claim 3, characterized in that the hyberbare shock is performed at a pressure of to bar for 1 to 4 minutes.

    In particular, it allows the diversification of livestock available for fish farming, with a hybrid with a higher market value. The advantages that flow from the present invention consist, essentially, in obtaining a sterile hybrid, having a good breeding yield and advantageous morphological characteristics.

    The invention relates to a method for obtaining a triploid interspecific hybrid of lean and another fish belonging to the Sciaenidae family comprising the following two steps: a crossing a lean Argyrosomus regius with another fish belonging to the family Sciaenidae b perform an induction treatment of triploidy on the progeny obtained. Indeed, the lean has a fine and tasty meat very appreciated and whose quality is comparable to that of other marine species raised.

    Moreover, it is not an essentially biological process. The tropical umbrella inhabits mainly coastal and estuarine waters from the northeast of the Atlantic Ocean to the Gulf of Mexico.

    A method according to any one of claims 2 to 7 comprising the following two steps: a crossing a lean male Argyrosomus regius with a female Sciaenops ocellatus ombrine, and b performing an induction treatment of triploidy on the progeny obtained. This technique has advantages over intraspecific hybridization that can lead to problems of loss of genetic diversity.

    Conventionally, the ombrine females have been induced by hormone injection. They were not enumerated so as not to add dangerous handling just after the stress of the trip.

    Additionally, triploids can provide a compromise between wild and stocked fisheries. More on Fish Untamed. The morphology of the resulting hybrid, which has a reduced head compared to lean, as shown in Figure 7, achieves significant gains in processing yields, which is a very interesting advantage compared to the objective initial, which was to obtain a hybrid with high commercial potential. In pressure treatment, the fertilized egg is given enough time to produce the polar body with the third chromosome, ready to be expelled.
