TLDR
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.Abstract:
During the summer of 1912 the Bureau of Fisheries with the cooperation of the Museum of Com;arative Zoology of Harvard Un~vers~ty, cOInInenced an oceanographic and bIOlogIcal survey of the Gulf of Maine, with special reference to its fishes to its floating plants and animals (Plankton), to the physical and chemical state of its waters and to the circulation of the latter. Cruises ;ere made on the Fisheries schooner Grampu8 during the summers and autumns of 1912, 1913, 1914, 1915 and 1916, and during the winters and springs of 1913 and 1915. The work Was interrupted by the war, but was resumed with a cruise of the Fisheries steamer Albatross in the late winter and spring of 1920, and was continued by the Fisheries steamer Halcyon during the winter and spring of 1920-21, and the summers of 1921 and 1922. The first part of the general report, dealing with the fishes was published in 1925, as Bulletin ~o (Pt. 1) of the United States Bureau of FisherIes; 1 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. The preparation of the section on the fishes was assigned originally to W. W. Welsh, who had gathered a large body of original observations on the growth, reproduction, diet, and other phases of the lives of many of the more important species. The report was far advanced when it was interrupted by his untimely death, and H. B. Bigelow ~dertook to carry it to publication along the Imes originally laid down. The new edition, entailing a general revision and the addition of In'Uch new lnaterial, has been prepared jointly by !: B. Bigelow and by W. C. Schroeder.read more

Effects of temperature and salinity on the survival of winter flounder embryos
TL;DR: The optimum temperature and salinity ranges for the development and sur vival of winter flounder embryos and larvae are reported and the relationship between the two fac tors as it affects embryo development is discussed.

Otolith microstructure of three larval gadids in the Gulf of Maine, with inferences on early life history
TL;DR: A detailed analysis of the assumptions underlying the application of otolith microstructure was undertaken for three gadid species from the Gulf of Maine, finding that daily increment counts provided a precise and accurate index of age in cod and haddock, but the widths of increments formed shortly after hatch approached the resolution limit of light microscopy.

Role of egg predation by haddock in the decline of an Atlantic herring population.
TL;DR: Evidence that egg predation by haddock can cause alternate stable population levels in Georges Bank Atlantic herring is presented and how efforts to rebuild fisheries can be undermined by not incorporating ecological interactions into fisheries models and management plans is illustrated.

TL;DR: It is shown that four general groups of cod can be distinguished: those of the northern Gulf of Maine heavily infcstcd, the moderately infested central and southern Gulf cod, the lightly infested Gcorgcs Bank population, and the southern New England group which is fret of infestation.

Environmental and Endogenous Factors Influencing Emigration in Juvenile Anadromous Alewives
TL;DR: Migration of juvenile anadromous alewives Alosa pseudoharengus at Bride Lake, a coastal lake in Connecticut, during summer 2006 and found that migration on 24-h and seasonal time scales was influenced by conditions of the environment and characteristics of the individual fish.
