| Au cours de l'année 1928, les travaux de la Station de Boulogne-sur-Mer sur la Biologie du Hareng se sont poursuivis, suivant le programme précédemment adopté et exposé, avec une intensité accrue : les mensurations s'étant étendues à plus de 5.000 harengs provenant des diverses régions de pêche de la Mer du Nord, de la Manche et de l'Atlantique, et les observations scalimétriques ayant porté sur près de 2.000 écailles préparées à la Station. Nous avons encore poursuivi nos prélèvements d'échantillons de la même façon, convaincus que des résultats plus probants doivent être obtenus par des prélèvements fréquents effectués dans chaque région, à des époques et en des points bien déterminés, plutôt que par un seul ou de rares prélèvements massifs effectués, à... |

| The repopulation of the oyster deposits of the Auray River seems to take place with a lot less intensity downstream than upstream. One might take into account the fact that the bottom of the oyster part of the river (Ours, Rohello, Loqueltas banks) counts less adult oysters than the top (Rosnarho, Plessis, Marie, Sainte-Avoye banks). But one must also note that the deposits stand next to each other and that the top of the most upstream bank is only 5 kilometres away from the bottom of the most downstream one. Consequently, the oyster larvae from the "abounding" part of the river can easily, thanks to the currents, go and fix in the "poorer" part. [...] |

| The pout belongs to the Gadidae family, which can be defined as follows: Fish with a more or less long body, covered with small smooth scales. Soft fins, 1 to 3 for the dorsal fins, 1 to 4 for the anal-pelvic fins located below the throat. Swim bladder and pyloric appendix generally existing. The Gadidae family is the largest of the sub-order of the Anacanthini, among the teleosts. |

| In a recent note I reported the high exceptional mortality which hit, in 1926, the young Portuguese oysters aged one month. I demonstrated that this mortality was caused by the high temperatures of August. The maximum was reached on the 25th of August, with 33°, and corresponds with the day the young oysters were affected. This temperature corresponded to a very high tide coefficient. In 1927, there was, as in any other year, a first fixation of the larvae on the collectors over the second fortnight of July and a second one around the 10th of August. At the end of this month, even if the temperature was not as high as the previous year and stayed constant, we still observed an abnormal mortality in the young oysters recently fixed and especially in those... |

| Le Merlu a toujours été très estimé et sa pêche est fort ancienne. Les souverains des Iles britanniques accordaient même, des privilèges aux étrangers moyennant certains droits pour leur permettre d'exercer cette pêche sur leurs côtes. Au IX° et X° siècles, les Danois avaient des pêcheries sur la côte d'Irlande. Sous le règne de la reine Mary, le roi Philippe II payait la somme de 1.000 livres pour conserver aux Espagnols le droit de pêcher dans les eaux irlandaises. Les Allemands avaient une autorisation semblable de Charles II, au prix de 30.000 livres, et " il était aussi garanti, comme une faveur », au royaume de Suède d'employer une centaine de bateaux à cette pêche (26). Avant la pêche sur les bancs de Terre-Neuve, le merlu salé remplaçait la morue,... |

| Au cours de l'année 1928, les travaux à la mer de la Station de Boulogne se sont poursuivis de la façon habituelle, et des embarquements ont été effectués, chaque fois qu'il a été possible, soit à bord des garde - pêche de la Station de la Manche et de la Mer du Nord, soit à bord des bâtiments de pêche, chalutiers ou drifters. Les garde-pêche de la Marine Nationale : Quentin-Roosevelt, Sentinelle et Estafette ont collaboré cette année encore, d'une façon très active aux travaux du Laboratoire de Boulogne, et, au cours de leurs croisières : à l'entrée occidentale de la Manche : sur les pêcheries de maquereaux, ou en Mer du Nord : sur les pêcheries harenguières, leur collaboration a été des plus précieuses par les nomhreuses et précises observations faites... |

| Numerous scientific works, some of which have been dealt with here, have demonstrated the important part played by the soiled shellfishes in the spreading of the typhoid fever. These works resulted in a stricter regulation of the fishery, the production and the commercialization of shellfishes, especially oysters; a regulation whose terms have been summarized and specified in the July 31, 1923 decree. This text focuses mainly on oyster production. Some of its articles, which deal with the freshness guarantee and the prohibition of some practices likely to soil the molluscs, either on the stalls or in the warehouse, can apply to all shellfishes. However, the decree's key article, requiring a healthy certificate of origin is only applicable to oysters. |

| In his work on the bream (Paf/ellus centrodonius'ï (1), Mr. R. Olivier gives the following figures on the gender proportionality in the breams: Females 60 % Males 30 % Hermaphrodites 10 %, which means that the bream normally is gonochoric, only 10 % of the individuals are hermaphrodites. And yet, on November 12th, 1927, at his request, I had provided the author with the following information: Out of 100 breams: 30 are functionally male, 60 are functionally female, and 10 have their sexual organs equally developed.

| During the summer of 1928, some observations were carried out by the laboratory of La Tremblade in order to initiate the study of the reproduction of the Portuguese oysters in the Marennes area. This issue is of a great interest as numerous oyster farmers and shippers set up various types of collectors each year in order to obtain Portuguese spats. [...] |
