Breeding Design for Atlantic Cod (Gadus morhua L.)
… family breeding program for Atlantic cod (Gadus morhua L.). The development of the base population began in the year 2003 when eggs were collected from wild brood fish from different spawning sites around Iceland. Approximately 350 viable families have been established and were later used …

Integrating bioenergetics and foraging behavior : the physiological ecology of larval cod (Gadus morhua)
How do larval cod, Gadus morhua, balance foraging effort against the high cost of swimming in a viscous hydrodynamic regime? A respirometry system was developed to measure the activity metabolism of individual larvae. The cost of swimming was modeled as a power-performance relationship (energy …

Individual variability in the behaviour and morphology of larval Atlantic cod (Gadus morhua, L.)
Individuals both within and between populations can vary markedly in a number of traits, including behaviour, life-history patterns and morphology. These differences do not simply reflect noise around a mean, but reflect real and important variability that can have a number of important …

Parasite abundance in Atlantic cod (Gadus morhua) in shallow and deep waters around Iceland
Proper stock identification of atlantic cod (Gadus morhua) is necessary in modern Icelandic fisheries management to ensure that stocks of cod are not overfished. Today the cod fishery in Iceland is treated as a single stock but studies have shown that there might in fact be two. In addition to …

Population variation in the life history traits and thermal responses of Atlantic cod, Gadus morhua L.
Studies of the phenotypes of animals at different parts of their geographic range often reveal striking variability. It is of considerable fundamental and applied interest to discover the extent to which such variation depends on genetic as opposed to environmental differences. A first step towards …

Control of sexual maturation and growth in Atlantic cod (Gadus morhua) by use of cold cathode light technology
The once abundant stocks of Atlantic cod in the North Atlantic have declined and now the fisheries are either severely restricted or even closed in order to preserve the remaining stocks. As a result, there is a growing interest in cod aquaculture to bridge the gap between decreasing supply and …

Effects of Pan-I genotype and family cross on oxygen consumption rate among juvenile Atlantic Cod (Gadus morhua)
Atlantic cod has been proved to be adapted genotypic and behavioural to different environmental temperatures. We compared the oxygen consumption rate (VO2/M) of juvenile Atlantic cod from both different family crosses and with different Pan-I genotypes acclimated to 4ºC, 8ºC and 12ºC and when …

Preventive Measures in Aquaculture: Isolation, Application and Effects of Probiotics on Atlantic cod (Gadus morhua L.) Rearing at Early Stages
… development at early stages of Atlantic cod (Gadus morhua L.) rearing. The first part of the study was designed to search for probiotics to target this critical period in cod rearing. Potential probionts were selected from the natural microbiota of cod larviculture at an experimental station …

The occurrence and behaviour of Pseudoterranova decipiens and Anisakis simplex (Nematoda) in Gadus morhua and their impacts on commercial processing
A Scottish seafood processor commissioned this study because the high prevalence of parasitic nematodes in their cod fillets meant they were unable to meet the standards demanded by their retailer. The aims were to determine which species of nematode were present, and whether the detection or …

The Comparative Effects of a Thermal Gradient on the Age and Growth Characteristics of Largemouth Bass (Micropterus Nigricans), and Atlantic Cod (Gadus Morhua)
… Bass (Micropterus nigricans) and Atlantic Cod (Gadus morhua) using data from peer-reviewed journals, state records, and fisheries agencies. For Largemouth Bass, I analyzed the relationships between air temperature (MAT<sub>min</sub>°C, MAT24hr°C, and MAT<sub>max</sub>°C), and growth parameters …

Food Resource Utilization By Five Species Of Benthic Feeding Fish In Passamaquoddy Bay, New Brunswick
… plaice (Hippoglossoides platessoides), cod (Gadus morhua) and witch flounder (Glyptocephalus cynoglossus). After reducing the size of the data matrix by removing redundant variables (prey items), interspecific diet overlap and the degree to which stomach contents reflect benthic composition …

Social capital and sustainability in a Newfoundland fishing community
… to what was its primary fishery, Northern cod (Gadus morhua). This ended in 1992 when the Canadian government implemented an indefinite moratorium on Northern cod. Historically the community has exhibited high levels of activism aimed for the most part at protectionism of its primary economic …

The development of a modular integrated recirculating aquaculture system using Porphyra (nori) for the bioremediation of marine finfish effluent
… rates were determined for Atlantic cod ( Gadus morhua L.) and nutrient uptake rates for Porphyra umbilicalis Kutzing and P. linearis Greville. The ammonium kinetic characteristics of the fish and seaweed were used to develop a model to predict the system ammonium dynamics. Integrated …

Photo-identification of White-Beaked Dolphins and their relations with Atlantic Cod and sea surface temperature fluctuations in Skjálfandi Bay, Iceland
… of its primary prey species, the Atlantic Cod (Gadus morhua), and the sea surface temperature fluctuations in Skjálfandi Bay, Iceland, over a period of ten years (2014-2024). The hypotheses suggest that an increase in sea surface temperature is expected to lead to a direct decline in the …

Ecological impacts of shrimp trawling on juveniles of selected benthic fish species in the southwestern Gulf of Maine

The use of multibeam and split-beam echo sounders for assessing biomass and distribution of spring-spawning Atlantic cod in the Gulf of Maine
… abundance of the spring-spawning Atlantic cod (Gadus morhua) in the western Gulf of Maine. Specifically, the main objectives of this research were 1) to test the feasibility of a multibeam echo sounder to detect changes in volume backscatter proportional to incrementally decreasing quantities of …

Challenges in Reconstructing Past Exploitations of Atlantic Cod: A Zooarchaeological Case Study from Early Medieval England
… have not been widely researched. Atlantic cod (Gadus morhua) was selected as the main focus of the study due to its prominence in modern and historical fishery economies, based on studies of modern and archaeological materials. Identifications of diverse marine taxa, including cod, were part of …
