Acclimation potential of Arctic cod (Boreogadus saida) from the rapidly warming Arctic Ocean.
As a consequence of the growing concern about warming of the Arctic Ocean, this study quantified the thermal acclimation responses of Boreogadus saida, a key Arctic food web fish. Physiological rates for cardio-respiratory functions as well as critical maximum temperature (Tc,max) for loss of equilibrium (LOE) were measured. The transition temperatures for these events (LOE, the rate of oxygen ...
متن کاملTemperature Modulates the Effects of Ocean Acidification on Intestinal Ion Transport in Atlantic Cod, Gadus morhua
CO2-driven seawater acidification has been demonstrated to enhance intestinal bicarbonate secretion rates in teleosts, leading to an increased release of CaCO3 under simulated ocean acidification scenarios. In this study, we investigated if increasing CO2 levels stimulate the intestinal acid-base regulatory machinery of Atlantic cod (Gadus morhua) and whether temperatures at the upper limit of ...
متن کاملEffects of ocean acidification on the calcification of otoliths of larval Atlantic cod Gadus morhua
The growth and development of the aragonitic CaCO3 otoliths of teleost fish could be vulnerable to processes resulting from ocean acidification. The potential effects of an increase in atmospheric CO2 on the calcification of the otoliths were investigated by rearing Atlantic cod Gadus morhua L. larvae in 3 pCO2 concentrations — control (370 μatm), medium (1800 μatm) and high (4200 μatm) — from ...
متن کاملIodine nutrition and toxicity in Atlantic cod (Gadus morhua) larvae
Copepods as feed promote better growth and development in marine fish larvae than rotifers. However, unlike rotifers, copepods contain several minerals such as iodine (I), at potentially toxic levels. Iodine is an essential trace element and both under and over supply of I can inhibit the production of the I containing thyroid hormones. It is unknown whether marine fish larvae require copepod l...
متن کاملDescription of Embryogenesis of Atlantic Cod Gadus Morhua
This paper presents a description of the embryonic development of Atlantic cod Gadus morhua. In addition, an equation describing the effect of temperature on developmental rate was developed. The whole period of embryogenesis was divided into 6 subperiods and 75 specific stages based on the distinctive characteristics. Temperature effects on the developmental rate of Atlantic cod embryos were s...
