Abstract
IN the Bulletin Trimestriel, 1911, the second part of the “Résumé des Observations” continues the summary of the plankton investigations carried out under the international programme in the north-east Atlantic and north-west European waters during the years 1902–8. The subjects here dealt with are the Copepoda, Tunicata, Ostracoda, Chaetognatha, Amphipoda, Rotatoria, and Ceratium. With the vast amount of material collected in course of the investigations external records are incorporated in a discussion of the seasonal occurrence and distribution of the species considered, and the hydrographic conditions associated in each case with such. The annual and seasonal distribution and intensity of many of the more important species are shown in a number of separate charts. From an economic point of view, attention is directed to the importance of many of the Copepoda and Amphipoda as constituting in a large measure the food supply of Clupeoids, Gadidae, the mackered, and other marketable fishes.
