| Artificial insemination mastery in red drum, Sciaenops ocellatus, requires a first experimental step wOOng at getting basic biological data. Regarding males, a relation between optical density of the solution (OD) measured by spectrophotometry and sperm concentration (SC) has been established : OD O,161*SC + 0,119. Mean sperm concentration measured is 4,36.10 10 spz.mL-1. This study shows an influence of the solution of dilution on spermatozoa motility and its evolution during short term preservation. As far as females are concemed, the follow-up of final maturation through the observation of samples taken during reguIar strippings, seems to he a good technique to limit overripening and spontaneous liheration of ovules. Some artificial insemination trials... |

| This article of the number 10 of Tai Kona is the natural complement to the article appeared under the number 8, dedicated to the submarine geodiversity of the New Caledonian EEZ. The first article notably put the bases of knowledge on the history, the origins and the specificities of the geodiversity of the maritime spaces of the New Caledonian EEZ. The present article focuses on four of the major stakes which are put: 1/ the scientific ones relative to an exceptional submarine geologic context, 2 /the economic ones connected to such a favorable geologic context and to mineral resources exploitation perspectives which are no more domain of the utopia, 3/ the major environmental ones with the existence of a semi deep and deep major biodiversity and 4/ the... |
