  • Early Stages of Fishes in the Western North Atlantic Ocean Volume
    ISBN 0-9689167-4-x Early Stages of Fishes in the Western North Atlantic Ocean (Davis Strait, Southern Greenland and Flemish Cap to Cape Hatteras) Volume One Acipenseriformes through Syngnathiformes Michael P. Fahay ii Early Stages of Fishes in the Western North Atlantic Ocean iii Dedication This monograph is dedicated to those highly skilled larval fish illustrators whose talents and efforts have greatly facilitated the study of fish ontogeny. The works of many of those fine illustrators grace these pages. iv Early Stages of Fishes in the Western North Atlantic Ocean v Preface The contents of this monograph are a revision and update of an earlier atlas describing the eggs and larvae of western Atlantic marine fishes occurring between the Scotian Shelf and Cape Hatteras, North Carolina (Fahay, 1983). The three-fold increase in the total num- ber of species covered in the current compilation is the result of both a larger study area and a recent increase in published ontogenetic studies of fishes by many authors and students of the morphology of early stages of marine fishes. It is a tribute to the efforts of those authors that the ontogeny of greater than 70% of species known from the western North Atlantic Ocean is now well described. Michael Fahay 241 Sabino Road West Bath, Maine 04530 U.S.A. vi Acknowledgements I greatly appreciate the help provided by a number of very knowledgeable friends and colleagues dur- ing the preparation of this monograph. Jon Hare undertook a painstakingly critical review of the entire monograph, corrected omissions, inconsistencies, and errors of fact, and made suggestions which markedly improved its organization and presentation.

The Committee reviewed environmental conditions in the Northwest Atlantic during 1999, convened a workshop on the Cod Recruitment Dilemma, reviewed additional papers on physical and biological oceanography and on changes in cod diets, and conducted its annual business meeting. 1. Physical Environment in 1999: Eight papers were reviewed on the meteorological and physical oceanographic conditions in 1999. Air temperature warmed relative to 1998 throughout most of the northwest Atlantic, reaching record high values in the Gulf of St. Lawrence, on the Scotian Shelf and over eastern Newfoundland. Sea ice coverage and duration were below average in most areas. Water temperatures from southern Labrador to the Grand Bank and off southern Newfoundland were generally above normal values.This was reflected in below-average volumes of the cold intermediate layer (CIL) and warmer- than-average bottom waters off Newfoundland, especially on the Grand Bank where bottom temperatures were 1-3°C above average.

    SECTION C 435 C-l C-1 REMARKS ON EFFECT OF FOOD ANIMALS ON COD BEHAVIOUR By Sv. Aa. Horsted and Erik Smidt1 ABSTRACT In Greenland waters cod make long spawning and feeding migrations. The most important feeding ugrations take place in early summer, when cod follow the capelin into the fjords to the shore, lnd later in the summer, when cod follow the launce over the banks in the Davis Strait and in coastal iaters. Later on cod have been observed feeding quite near the shore in coastal areas, where the food consists of small capelin, Arctic squid and euphausiids. Cod may also be concentrated near lcebergs in summer and autumn. Finally. when cod have disappeared from the upper water layers be­ :ause of winter cooling, large numbers can be taken on the prawn grounds, where PandaZua borealis Ls the main food. COD PURSUING THE CAPELIN INTO THE FJORDS IN THE EARLY SUMMER In West Greenland large shoals of capelin (Mal lotus villosus) migrate into many 'of the fjords :or spawning, and in Southwest Greenland they are often pursued by cod. Both when the capelin ,efore spawning swim in shoals over the deeper parts of the fjords and coastal waters and when they ~ather near shore to spawn, one can follow the cod hunting them right up to the surface (Hansen, L949, p. 40), and investigations of cod stomachs show that they are full of capelin. During this Jeriod it is often difficult to catch cod with jig or long-line, as they pay no attention to the looks, even when baited with fresh capelin.

In this study I examine trophic vulnerability of 0-group Atlantic cod (Gadus morhua) and saithe (Pollachius virens) during late summer and fall. This period coincides with the Atlantic cod juvenile settlement from the pelagic to the benthic habitat in the northwest of Iceland.

Swedish University of Agricultural Sciences Faculty of Natural Resources and Agricultural Sciences Department of Aquatic Resources Abstract Pelagic and demersal cod (Gadus Morhua) specimens were collected respectively during a pelagic and a demersal survey in the Eastern Baltic sea in the fourth quarter of the years 2015-2017. Stomach contents were analysed and compared for the pur- pose of evaluating differences in the diet among pelagic and demersal specimens. Furthermore, generalized additive models (GAMs) were employed to investigate the daily fluctuations of stomach content weights of this predator. My results showed significant differences in the diet composition of demersal and pelagic cod mainly attributable to the higher weight share of sprat in the pelagic stomachs. Moreover, a remarkable diel variation in the stomach contents weights was present, indicating morning and evening peaks. The present study furnished novel insights into cod feed- ing pattern in the South-Western Baltic Sea.
