Ammonia distribution and excretion in fish

Fish Physiology and Biochemistry, 1987
This paper reviews the literature concerning ammonia production, storage and excretion in fish. Ammonia is the end product of protein catabolism and is stored in the body of fish in high concentrations relative to basal excretion rates. Ammonia, if allowed to accumulate, is toxic and is converted to less toxic compounds or excreted.

Distribution and translocation of micro- and nanoplastics in fish

Critical Reviews in Toxicology, 2021
Microplastics (MPs) and nanoplastics (NPs) are regarded as emerging particulate contaminants. Here, we first summarize the distribution of plastic particles in fish. Field investigations verify the presence of various kinds of fibrous, spherical, and fragmentary MPs in fish gastrointestinal tract and gills, and specifically in muscle and liver ...

The Distribution of Freshwater Fishes

Nature, 1926
As a mere sciolist in geology it sometimes occurs to me to wonder whether enough attention has been given to the distribution of freshwater fauna, in estimating the origin of British land contours and the course of rivers. It is generally accepted that until the North Sea was formed by an extensive subsidence of land in an age not geologically remote ...

Nonuniform distribution of enzymes in fish eggs

Journal of Experimental Zoology, 1982
AbstractThe distribution of enzymes in the blastoderm and the yolk was investigated in the eggs of the bony fish, Misgurnus fossilis. The total activities of lactate dehydrogenase (LDH), glucose‐6‐phosphate dehydrogenase (G‐6‐PD), and aldolase (ALD) did not change during early development.

A Size Distribution Model Applied to Fish Farming

2003
This paper presents an age-structured control model applied to the size variability problem in fish farming. This phenomenon is common in commercial culture due to the principal of competition among individuals in ecosystems with high density. The usual consequences are higher differences in fish growth, together with an increase in mortality rate ...

Occurrence and Distribution of Catecholamines in the Fish Brain

Acta Physiologica Scandinavica, 1961
AbstractRelatively high amounts of catecholamines were found in the brains of an elasmo‐branch, Squalus acanthias and a teleost, Gadus callarias. Only small quantities could be demonstrated in the brain of a cyclostome, Myxine glutinosa. Both adrenaline and noradrenaline occurred in the brains of Squalus and of Gadus although noradrenaline was ...
