Interannual variation in condition of the mackerel icefish
Journal of Fish Biology, 1997 Mackerel icefish Champsocephalus gunnari are widespread on the South Georgia (54° S, 36° W) shelf. Analysis of condition indicated a strong interannual variation. High condition indices, indicative of good feeding conditions, were present when krill were abundant in the region. Years when krill were scarce and condition index was consequently low, were

The lactate dehydrogenase of the icefish heart: biochemical adaptations to hypoxia tolerance
BBA - Proteins and Proteomics, 1991 Cardiac lactate dehydrogenase from the hemoglobin- and myoglobin-free antarctic icefish has been purified by affinity chromatography. Structural and kinetic properties of the enzyme were found close or identical to those of its skeletal muscle counterpart and other M-type lactate dehydrogenases.

Investigations Of Demersal Mackerel Icefish (C.Gunnari)
, 2003 No abstracts are to be cited without prior reference to the author.Conventionally, quantitative assessment of mackerel icefish C. gunnari, as a demersal fish species, has been made based on the results of inventory bottom trawling surveys in Subarea 48.3.

Immunolocalisation of angiotensin II receptors in icefish (Chionodraco hamatus) tissues
Journal of Endocrinology, 1997 Abstract The monoclonal antibody 6313/G2 raised against the mammalian type I (AT1) angiotensin II (Ang II) receptor (Ang II-R) also recognises a component in teleost (eel) tissue preparations that binds radiolabelled Ang II, and has an isoelectric point (pI) of 6·5 and molecular mass of 75 kDa.

Adaptations of the hemoglobinless Antarctic icefish (Channichthyidae) to hypoxia tolerance
Comparative Biochemistry and Physiology A, Comparative Physiology, 1997 peer reviewedAntarctic fish of the family Channichthyidae, or icefish, represent a unique model for the study of physiological and biochemical responses to chronic hypoxia since the genes coding for hemoglobin and possible myoglobin are not expressed by ...

Daily otolith increment validation in larval mackerel icefish, Champsocephalus gunnari
Fisheries Research, 2005 Mackerel icefish, Champsocephalus gunnari, larvae were sampled by weekly plankton tows in Cumberland Bay South Georgia. The formation of daily growth increments in sagittal otoliths was validated from larvae sampled 34 days apart. A mean increase of 33.7

Evolution of the myoglobin gene in Antarctic Icefishes (Channichthyidae)
Polar Biology, 2010Antarctic icefishes (Family: Channichthyidae) are the only adult vertebrate animals that do not express the circulatory oxygen-binding protein, hemoglobin. Six species of icefishes, including Dacodraco hunteri, also do not express myoglobin (Mb), an oxygen-binding protein found in ventricular tissue of Antarctic notothenioids.

Evolutionary Adaptation and Disaptation in the Cold: the Icefish Paradigm
2012The aim of this chapter is to illustrate in the context of cold adaptation of the Antarctic teleosts the icefish as a unique case-study of physiological responses to genetic changes, i.e. loss of hemoglobin (Hb) and myoglobin (Mb), without apparent immediate compensatory mutations.
