In 1961, as in previous years, two observers collected data aboard the trawlers "Vendaval" and "Aquilon", mainly for the study of length and age distribution of cod. B.- Age and Growth of Cod caught by Spanish Fishing Vessels in the Northwest Atlantic Ocean in 1961. A. Figueras Monfort. The paper presents a summary of the results of investigations on the cod (Gadus morhua) in the ICNAF Convention Area in 1961. The summary includes growth and corresponding mean lengths by age-groups; relative abundance of year-classes by divisions of area; age at first spawning; and proportion of sexes. C.- Observations on the Fishery in Subareas 2 and 3 Made by Captains of Spanish Trawlers. J.L. Arambarri. The fishing season in Subareas 2 and 3 which are closely related from the point of view of the Spanish commercial fishermen, lasted for the Spanish trawlers from the last days of April until December, 1961. About 90% of the fishing days were spent on the Belle Isle ground (3K) and the Hamilton Bank (2J). The peak of the fishing occurred in May, thereafter it gradually decreased to a low catch through the summer and until October, with the minimum catch in August. During this period a few occas-ional good catches were obtained. In 3K and 2J, May was the best month of the whole season. The average size of the cod (total length) was close to 60 cm
