Figure 8.21 Route followed by fish larvae from the spawning ground to eventual settlement on
Georges Bank (based on Lough and Manning, 2001, with permission from Elsevier).
(a) The path followed by developing fish larvae within the along-bank residual jet
(see Fig. 8.7a ), transferring them from the spawning ground to eventual settlement on the
Bank. (b) Schematic of the mechanism that transfers larvae from the jet onto the bank. Arrows
indicate the directions of the residual flows within the front.
