On the Seasonal Abundance of Young Fish. V. the Year 1937

Abstract

The present report continues the observations on the seasonal abundance of the pelagic young of teleostean fish in the plankton off Plymouth(Russell, 1937) and gives the results for the year 1937. These results are published in the same form as in previous reports. The dates on which collections were made with the 2-metre stramin ringtrawl are given in Table I and the monthly average catches of the young fish per half-hour haul in Table II. In Fig. 1 is given the curve for the average catches for each fortnight of all young fish, excluding clupeids, and superimposed upon this the corresponding curve for the average catches over the period 1930–1934 inclusive.
