Breeding Design for Atlantic Cod (Gadus morhua L.)
… of the Icelandic 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 …

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 …

Individual variability in the behaviour and morphology of larval Atlantic cod (Gadus morhua, L.)
… useful in the rearing of species such as Atlantic cod, which are highly cannibalistic in the larval and early juvenile period of development. The purpose of the work outlined in this thesis was to elucidate certain aspects of individual variability in predominantly larval cod that relate …

Population variation in the life history traits and thermal responses of Atlantic cod, Gadus morhua L.
… the population and thermal responses of Atlantic cod, a species with a wide distribution and geographic variation in life history traits. Life history traits were investigated in cod from three areas around the British Isles of differing thermal regimes, namely St Andrews Bay on the …

Challenges in Reconstructing Past Exploitations of Atlantic Cod: A Zooarchaeological Case Study from Early Medieval England
… which to date 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, …

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 …

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 …

Preventive Measures in Aquaculture: Isolation, Application and Effects of Probiotics on Atlantic cod (Gadus morhua L.) Rearing at Early Stages
… and larval 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 …

Photo-identification of White-Beaked Dolphins and their relations with Atlantic Cod and sea surface temperature fluctuations in Skjálfandi Bay, Iceland
… one 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 …

The Comparative Effects of a Thermal Gradient on the Age and Growth Characteristics of Largemouth Bass (Micropterus Nigricans), and Atlantic Cod (Gadus Morhua)
… on Largemouth 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 …

The use of multibeam and split-beam echo sounders for assessing biomass and distribution of spring-spawning Atlantic cod in the Gulf of Maine
… measure of 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 …
-
The Effects of Global Change on Avian Biodiversity
… I used relationships between abundances of Atlantic Cod and other fish and invertebrate species to improve predictions of Atlantic Cod, whose populations have declined dramatically. These improved predictions can enhance management and reduce bycatch of cod. In each of these cases, …

Biophysical interactions in the Iceland Basin
The Iceland Basin in the N. Atlantic has attracted considerable recent attention because the spring bloom in this region acts as the most powerful biological carbon pump anywhere in the world oceans. Furthermore, the link between primary productivity and herbivory by the calanoid copepod, Calanus …

Profiling extracellular vesicles signatures and deiminated protein cargo across phylogeny and pilot assessment of in vitro application of EVs in tissue regeneration, with focus on selected taxa displaying unusual immunological properties.
… the regenerative potential of EVs derived from Atlantic cod mucus and serum. Proteomic analysis of cod-derived EVs uncovers a distinct cargo of proteins contributing to wound healing processes. Functional assays demonstrate the efficacy of cod serum-derived EVs in enhancing wound closure and …

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 …

The development of a modular integrated recirculating aquaculture system using Porphyra (nori) for the bioremediation of marine finfish effluent
… production 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. …

Ecological impacts of shrimp trawling on juveniles of selected benthic fish species in the southwestern Gulf of Maine
… flounder (Pseudopleuronectes americanus), and Atlantic cod (Gadus morhua) were the four species selected for study. Only H. platessoides and M. bilinearis were caught in sufficient numbers to enable the correlation of their abundance with environmental variables ordered into PCs. The result was …

Investigating group behavioral quantization of oceanic fish with Continental-shelf scale ocean-acoustic sensing
… continental-shelf scale acoustic measurements of Atlantic cod over thousands of square kilometers using towed source and receiver arrays were made by an international, multi-disciplinary team led by MIT researchers including myself in the historic Lofoten cod spawning ground in Norway during the …

Instantaneous continental-shelf scale sensing of cod with Ocean Acoustic Waveguide Remote Sensing (OAWRS)
Reported declines in the population of Atlantic cod have a potential to affect long-term ecological balance and the sustainability of the cod fishery along the US northeast coast. These assessments have led to severe fishing cuts over the past few years, have consequently threatened the …

Creating sense from non-sense DNA: de novo genesis and evolutionary history of antifreeze glycoprotein gene in northern cod fishes (gadidae)
Gadids (cod fishes) are ecologically prominent and important species of the north polar marine fauna. Seven gadid species are known to have evolved antifreeze glycoproteins (AFGPs) that enable their survival from inoculative freezing by environmental ice in frigid Arctic and sub-Arctic waters. …
