Book excerpt: A comprehensive handbook, covering all aspects of the Atlantic cod including the biology, ecology, life histories, behaviour, commercial exploitation and conservation Not only is Atlantic cod one of the most valuable food fish in the world’s oceans, it is an important component of North Atlantic ecosystems and has been subject to much research into its biology, ecology and exploitation. After hundreds of years of exploitation, overfishing in the last half of the 20th Century caused many stocks to collapse, most famously the Northern cod stock off Newfoundland and Labrador, Canada. Since then, most cod stocks have been better researched and managed, but remain in a variety of states, from fully recovered to continued decline. This book, written by world experts, describes that research and management, and the importance of cod and its fisheries on North Atlantic cultures and economies, with impacts well beyond the range of the species. Atlantic Cod: Bio-Ecology of the Fish offers insightful chapter coverage of cod nomenclature, taxonomy, phylogeny and morphology; physiology and ecophysiology; reproduction and spawning behavior; early life history and pre-recruitment processes; migrations, movements and stock identity; feeding, growth and energetics; the place of cod in the ecosystem; the exploitation of cod through history and present day commercial fisheries and precautionary management for sustainable fisheries; impacts of climate change on cod biology and ecology; and the future of the species and its fisheries. Discusses the major commercial importance of Atlantic cod through history Provides a comprehensive treatment of the bio-ecology of the most researched and highly exploited fully marine species Examines how the decline (and recovery) of cod stocks is of great political and scientific interest An essential purchase for marine fisheries scientists Atlantic Cod: Bio-Ecology of the Fish is a vital book for all fisheries scientists, managers and fish biologists.

This book was released on 2014 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis examined the effects of partial dietary supplementation with wild- zooplankton or fish protein hydrolysate on cod production traits, and how they related to the cod's physiology and the expression of growth and appetite regulating genes. Atlantic cod larvae were fed three different diets: enriched rotifers / Artemia (RA); RA + fish protein hydrolysate (RA-PH); and RA supplemented with 5-10% wild zooplankton (RA-Zoo). Partial supplementation with zooplankton significantly improved the dry weight at 60 dph (by approximately 4-fold), specific growth rate (by 2.5% day-1) and the general development of cod larvae. In contrast, the protein hydrolysate enrichment did not improve growth, had a negative effect on survival, and increased the incidence of external deformities in 18 month post-hatch juveniles. Although the zooplankton fed cod were still larger at approximately 1.5 years of age, the growth advantage of this group decreased with age (the difference in wet mass decreasing from approx. 30% at 0.5 years old to 11% at 1.5 years old). Metabolic parameters, and pre- and post-stress cortisol levels, were similar in juvenile cod from the RA and RA-Zoo groups. Finally, the growth enhancement observed in the zooplankton fed larvae was not related to alterations in the mRNA expression of the main growth regulating genes [Insulin-Like Growth Factor 1 (IGF-1); IGF-2; Growth Hormone (GH); GH Receptor-1 (GHR-1); GHR-2; and myostatin] or appetite regulating hormones [(Cocaine and Amphetamine Regulated Transcript (CART) and Neuropeptide Y (NPY)]. This latter finding suggests that the transcript levels of these hormones and hormone receptors are not a valuable biomarker for growth in cod larvae.

This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Human-induced climate change has been affecting oceans' temperatures for several decades (IPCC, 2014). Temperature is one of the most important environmental factors influencing metabolic rates and therefore development, growth and reproduction of terrestrial and marine organisms (Clarke, 2017). Growth rates of ectotherms (e.g. fish species) are expected to be altered by climate-induced temporal and spatial changes in ocean temperatures (Pörtner, 2010; Pörtner et al., 2014). Studies suggest that warming will have differential effects on fish body size with the major trend of reduction in mean species size across latitudes (Forster et al., 2012; Cheung et al., 2013; Audzijonyte et al., 2020). The thesis aims to bridge advanced knowledge and methodology of various kinds of research, such as climate physics and climate modelling, theoretical, experimental and observational biology, and biophysical modelling in order to investigate temperature effects on fish growth from both historical and future climate perspectives. In particular, the study is dedicated to the main subject - the role of different thermal environments in shaping the growth patterns of Atlantic cod (Gadus morhua) with the focus on the Northeast Atlantic populations. Additionally, the author addresses methodological aspects, advantages and limitations of a modelling study in a context of eco-physiological research and introduces an open source modelling tool that can help link findings from experimental (physiology) and observational (ecology) studies.

This book was released on 2011 with total page 52 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Mariculture of Atlantic cod (Gadus morhua) in the Bay of Fundy was initiated in the early 2000s and early maturation has been a persistent problem since its inception. The objectives of the present study were to evaluate, over separate two-year periods, whether 20 and 24 h light exposure compared to natural photoperiod in sea cages will (i) increase body growth, (ii) halt or delay sexual maturation, (iii) influence investment in reproductive tissue as reflected in gonad weight, and (iv) affect seasonal levels of water content in muscle and liver tissue of Atlantic cod."
