| Two international research cruises on board of the research vessel 'Ichthys' the first one in Aug-Sept 1971, and the second other in June-July 1972, have shown the reproduction of Thunnus thynnus, T.alalunga, Auxis thazard and Sarda in the surroundings of the Balearic Islands. The observations were made on the planctonic stages of these spp and on the physico-chemical and biological conditions of the environment. Some data were also collected on the presence of juvenile or mature stages of these fishes and on their fishery. |

| Ce problème pouvait être abordé de deux façons différentes; il était en effet possible soit de s'orienter vers les technIques Japonaises (expérimentations en semi-intensif avec utilisation de grands volumes supérieurs au m3 , procédés donnant des résultats Immédiats mais à reproductivité incertaine, emploi d'une main-d'oeuvre nombreuse et peu spécialisée), soit d'adopter pour le système clos à forte production contrôlée (mis en oeuvre assez longue, investissement immédiat plus important, utilisation en série de petits volumes à forte concentration, nourriture naturelle produite artificiellement et donnée en quantité connue, main-d'oeuvre peu abondante mais très spécialisée) . Pour une meilleure connaissance des problèmes et pour une adaptation future plus... |

| The problem of the clogging up of sea water pipes by Mytilus edulis larvae is a very real problem. A study has been made of the ways to destroy these larvae, (1) by electricity (publication in preparation), (2) by ultrasound. This last technique has given interesting data, but exploitation of results on a large scale presents many difficulties. An interesting general phenomenon is to be underlined. For ultrasound treatments of short duration (10s), many larvae are simply stressed and recover later on. For longer treatments, there is actual dislocation of the larvae and instant mortality, this mortality increases with time. |

| For characterization of strains of the brine shrimp <i>Artemia</i> of different geographical origin, a standard culture test has been developed in order to compare statistically growth and survival of larvae of different strains. 25 geographical strains have been studied so far -including, for 3 strains, analyses of cysts harvested at different times. Important differences in rates of growth and survival were observed between strains but not among batches of the same strain. Best performances were noted for strains from Bahia Salinas (Puerto Rico), Buenos Aires (Argentina), Chaplin Lake (Canada), Great Salt Lake (Utah, USA), Galera Zamba and Manaure (Colombia). |

| Using a continuous breeding of T. brevicornis the authors try to approach an experimental procedure in order to estimated the effects of thermal stresses on larvae produced by ovigerous females. In spite of the main factor driving to successful breeding was the healthiness of algal food, sublethalt or inhibitory effects were observed with duration were only observed to LT 50 level. On opposite, decrease in nauplii production is noted just after ovigerous females are exposed to 35 degree C of final temperature. |
