Depth-frequency diagrams and trap results of Tortanus discaudatus females and males during the 24-h study. Incident radiation recorded on deck is indicated in the upper panel; arrows indicate sunset and sunrise. The actual number of individuals moving up or down into the traps at 8, 14, 21 and 28 m is indicated next to each arrow. Trap deployment and retrieval time was set to coincide with the middle of adjacent horizontal, net-tow series. The 25 and 75 % population quartiles are connected by broken lines and the population median is indicated by a black dot. The number located inside each depth-frequency diagram (scale lower right) is the estimated number of individuals/ m3 in the water column during this series of horizontal net tows. Sampling for eight and four periods, respectively, between 10:30 August 19 and 09:30 August 20, 1980, at St. Georges Bay, shallow marine embayment open on the north to Northumberland Strait and the southern Gulf of St. Lawrence.
Nota: Engine and deployment of mooring traps figured in Harding & al. (1987) and Harding & al. (1986).
