| Mature eggs were expressed from captured female and fertilised artificially with slightly bloody sperm, in dry conditions or in a humid atmosphere, both at 13 degree C. The best incubation conditions proved to be 13 degree C, with streptomycin and penicillin. Another sample was kept at 18 degree C. Hatching occurred after 4 or 5 days, larvae showing positive phototropism. The system of renewal of water and artificial food is described. The embryonic reserve drop of lipid disappeared between day 14 and 16. Observations on larvae were like previous ones, but live larvae had larger mouths than had fixed specimens, and it was found that temperatures of 13 degree C or 18 degree C were suitable beyond the egg stage. A sudden change in temperature caused by a... |

| Before I get to the heart of the matter, I would like to precise the main objectives of this cruise as well as the conditions in which it took place. A year earlier, we had managed to obtain for the first time 12 000 Atlantic wolffish fries from farmed spawners. Therefore we had to demonstrate that these experiments were repeatable and that they could be adapted to a mass production leading to the rearing of 30 000 to 50 000 fries. These are the terms of the collaboration contract between the C.N.E.X.O. and the Sete Station. |

| On Languedoc shore, several hatcheries may be used at research and development level, to solve tuna aquaculture problems. Therefore, incubation and hatching of air-transported eggs collected on spawning ground with different technics are possible. Natural zooplancton now used to feed bass larvae in Sète is to be used for tuna rearing. |
