TLDR
Ammodytes americanus larvae were collected from 22 stations in the Atlantic Ocean and 3 in the Chesapeake Bay from January through April, 1960 as discussed by the authors, and the rate of larval development was approximated at 11.7 mm per month for the first four months.Abstract:
Plankton samples were collected monthly from 22 stations in the Atlantic Ocean and 3 in Chesapeake Bay. Numerous larvae of sand lance,Ammodytes americanus, were taken from January through April, 1960. Larvae were widely distributed over the survey area but were most abundant beyond 25 miles from shore. Statistical analysis of sample mean lengths indicated movement offshore and a tendency for a group hatched together to remain together. Rate of larval development was approximated at 11.7 mm per month for the first four months. It is believed that spawning occurred at 5–12 fathoms in the study area. Hatching began in late November, reached a peak sometime after mid-December, and continued until mid-March. Few larvae were collected in waters with salinities less than 30%.read more

TL;DR: The first part of the general report, dealing with the fishes was published in 1925, as Bulletin of the United States Bureau of FisherIes, and subsequent parts describing the plankton of the offshore waters of the Gulf and the physical Characteristics of its waters were published in 1926-27, as Part 2. as discussed by the authors.

TL;DR: Analyses in the gulf of Maine and bay of Fundy show the zooplankton population to be dominated by a relatively few species of boreal endemic crustaceans.
